Free CPNP-PC Practice Test: 60 Questions With Explanations

Correct answer: A. Complete the M-CHAT-R/F Follow-Up interview for the items that screened at risk.

On the M-CHAT-R, a total of 3 to 7 is medium risk, and the scoring algorithm calls for the Follow-Up interview on the at-risk items. If the Follow-Up score is 2 or higher, the child has screened positive and should be referred for diagnostic evaluation and early intervention eligibility. A Follow-Up score of 0 or 1 is a negative screen.

Why the other choices are less suitable:

• B. That is the plan for a low-risk total of 0 to 2.
• C. Referring without the Follow-Up is the path for a high-risk total of 8 to 20.
• D. The algorithm's next step is the Follow-Up interview, not a delayed repeat.

Takeaway: M-CHAT-R total of 3–7: do the Follow-Up interview before deciding.

Correct answer: B. Supine on a flat, firm, separate infant surface in the parents' room, with no inclined or weighted products.

The AAP's 2022 safe sleep policy recommends placing infants on their backs on a firm, flat, non-inclined surface; room-sharing without bed-sharing, ideally for at least the first 6 months; and avoiding weighted sleep products and inclined sleepers. Supporting breastfeeding still matters, but it doesn't change the sleep-surface advice.

Why the other choices are less suitable:

• A. The AAP advises a flat, non-inclined sleep surface; inclined products are not safe for sleep.
• C. The AAP advises against weighted sleep sacks, swaddles, and blankets.
• D. The AAP recommends room-sharing without bed-sharing.

Takeaway: Back to sleep on a flat, firm, separate surface in the parents' room—nothing inclined or weighted.

Correct answer: A. Amoxicillin-clavulanate: amoxicillin 90 mg/kg/day plus clavulanate 6.4 mg/kg/day, divided twice daily, for 10 days.

The AAP's AOM guidance uses high-dose amoxicillin (80–90 mg/kg/day) first-line but switches to amoxicillin-clavulanate—90 mg/kg/day of the amoxicillin component with 6.4 mg/kg/day of clavulanate, divided twice daily—when the child has had amoxicillin in the past 30 days, has concurrent purulent conjunctivitis, or has recurrent AOM that didn't respond to amoxicillin. Her fever is a severe feature; the AAP course table calls for 10 days in children with severe symptoms.

Why the other choices are less suitable:

• B. Amoxicillin within the past 30 days calls for beta-lactamase coverage.
• C. Azithromycin isn't among the recommended first-line regimens for AOM.
• D. A temperature of 39 °C or higher is a severe feature; antibiotics are indicated now, not observation.

Takeaway: Amoxicillin in the past 30 days: switch to high-dose amoxicillin-clavulanate.

Correct answer: A. Send a backup throat culture, and arrange to treat if it is positive.

RADTs are highly specific but vary in sensitivity. CDC advises following a negative RADT with a throat culture in symptomatic children older than 3 years, with a plan to contact the family and start antibiotics if the culture is positive; treating confirmed strep lowers the risk of acute rheumatic fever. A positive RADT doesn't need a backup culture.

Why the other choices are less suitable:

• B. Exam findings alone can't confirm strep; antibiotics are for confirmed infection.
• C. A negative RADT in a child this age needs a backup culture.
• D. Repeating the antigen test doesn't replace the recommended culture.

Takeaway: Child over 3 with a negative RADT: send a backup throat culture.

Correct answer: B. Give both vaccines today; a household member's pregnancy is not a reason to delay them.

CDC's table of conditions incorrectly perceived as contraindications includes pregnancy of the recipient's mother or another household contact, for both MMR and varicella vaccines. Contraindications and precautions are judged in the person receiving the vaccine, and this healthy 12-month-old has none.

Why the other choices are less suitable:

• A. No contraindication exists, so waiting only leaves the child unprotected longer.
• C. CDC lists a pregnant household contact as a misperceived contraindication for varicella vaccine as well as MMR.
• D. The mother's immunity doesn't decide whether her child can be vaccinated; contraindications are judged in the child.

Takeaway: A pregnant household contact is not a reason to delay MMR or varicella vaccine for the child.

Correct answer: D. Attempt clinician-performed reduction using hyperpronation of the forearm.

This history and exam fit radial head subluxation (nursemaid's elbow). Reduction is appropriate in this typical presentation. The Royal Children's Hospital guideline describes both hyperpronation and supination-flexion; hyperpronation is the appropriate reduction option offered here. Reassess arm use afterward. Atypical findings or unsuccessful attempts require reassessment and may require imaging.

Why the other choices are less suitable:

• A. Imaging is not routinely needed for a classic pulled elbow without swelling, deformity, or focal bony tenderness; atypical findings or failed reduction change that decision.
• B. Splinting doesn't reduce the subluxation; a reduction maneuver is the treatment.
• C. A trained clinician can attempt reduction in a typical uncomplicated case; specialist referral is not required before every first attempt.

Takeaway: Classic nursemaid's elbow without injury red flags: attempt reduction and reassess arm use.

Correct answer: C. Ferrous sulfate 3 mg/kg of elemental iron daily, reduce excessive milk intake, and arrange follow-up to assess response.

His excessive milk intake, few iron-rich foods, microcytic anemia, and low ferritin fit iron deficiency anemia. Oral iron and dietary change address both the deficiency and its cause. The Royal Children's Hospital guideline recommends 3–6 mg/kg/day of elemental iron for treatment; 3 mg/kg/day is the appropriate lower-end treatment dose offered here. Reduce excessive milk, add iron-rich foods, and follow the blood count and iron stores to document response.

Why the other choices are less suitable:

• A. His history, microcytic anemia, and low ferritin already confirm iron deficiency anemia.
• B. This otherwise well child needs oral iron and dietary treatment, not a routine red blood cell transfusion.
• D. His blood lead level is low; chelation has no role here.

Takeaway: Toddler with iron deficiency anemia from excess milk: reduce excessive milk, give an appropriate elemental-iron treatment dose, and follow the response.

Correct answer: A. Apply fluoride varnish today, repeat every 3 to 6 months based on caries risk, and refer to a dental home.

The Bright Futures/AAP periodicity schedule recommends applying fluoride varnish to all infants and children starting at primary tooth eruption, then every 3 to 6 months in the primary care or dental office based on caries risk. It also calls for checking whether the child has a dental home and referring if not.

Why the other choices are less suitable:

• B. Fluoride varnish is recommended from the time the first tooth erupts.
• C. Oral fluoride supplements are considered only when the primary water source is deficient in fluoride.
• D. One erupted tooth is enough to start.

Takeaway: Fluoride varnish starts at first tooth eruption; oral supplements only if the water is fluoride-deficient.

Correct answer: A. Supportive care, including nasal suctioning and fluids, with clear return precautions.

The Royal Children's Hospital bronchiolitis guideline bases diagnosis and severity assessment on the history and exam and recommends against albuterol, epinephrine, systemic corticosteroids, and routine radiographs or lab tests. Care is supportive, with fluids if the infant can't stay hydrated by mouth.

Why the other choices are less suitable:

• B. Bronchodilators are not routinely recommended for typical bronchiolitis.
• C. Systemic corticosteroids are not recommended for bronchiolitis.
• D. Routine imaging and lab tests aren't recommended; the diagnosis is clinical.

Takeaway: Bronchiolitis: supportive care; no albuterol, steroids, or routine X-rays.

Correct answer: C. Two yes answers in Part B indicate higher risk and the need for further assessment.

On CRAFFT 2.1, any reported use in Part A means asking all six Part B questions. The form states that two or more yes answers suggest a serious problem and the need for further assessment. Her two yes answers meet that threshold.

Why the other choices are less suitable:

• A. Two or more yes answers is the threshold for further assessment.
• B. The CRAFFT threshold is 2.
• D. Asking only the CAR question applies when Part A shows no use at all.

Takeaway: CRAFFT: any use means all six questions; 2 or more yes answers means further assessment.

Correct answer: A. A temperature of 38.5 °C (101.3 °F) or higher needs immediate medical evaluation.

Children with sickle cell anemia are at high risk for invasive bacterial infection. NHLBI guidance teaches families and clinicians that a fever of 38.5 °C (101.3 °F) or higher is an emergency needing prompt evaluation. Daily penicillin through at least age 5 and vaccination reduce the risk, but they don't remove it.

Why the other choices are less suitable:

• B. Waiting for a higher fever delays care for a possible serious bacterial infection.
• C. Fever in a child with sickle cell anemia is treated as an emergency, not watched at home.
• D. Prophylaxis lowers the risk of invasive infection but doesn't eliminate it.

Takeaway: Sickle cell disease plus fever of 38.5 °C or higher = immediate evaluation.

Correct answer: B. Doxycycline 100 mg by mouth twice daily for 7 days, with retesting in about 3 months.

CDC's 2021 STI treatment guidelines made doxycycline 100 mg twice daily for 7 days the recommended chlamydia regimen for adolescents and adults, with azithromycin 1 g once or levofloxacin as alternatives; azithromycin is recommended in pregnancy. Retesting about 3 months after treatment is recommended because reinfection is common.

Why the other choices are less suitable:

• A. Azithromycin is an alternative (and the recommended regimen in pregnancy); doxycycline is preferred for nonpregnant adolescents.
• C. That regimen treats gonorrhea, not chlamydia.
• D. Metronidazole treats trichomoniasis, not chlamydia.

Takeaway: Chlamydia, not pregnant: doxycycline for 7 days; retest at 3 months.

Correct answer: A. Order a hip ultrasound at about 6 weeks of age.

Breech presentation remains a risk factor even when the newborn hip examination is normal. Seattle Children's pathway recommends an ultrasound at 6 weeks followed by a single AP pelvis radiograph at 6 months for breech infants. The normal examination does not end surveillance. This planned screening schedule is not a reason to delay evaluation of an abnormal hip examination.

Why the other choices are less suitable:

• B. For a breech infant with a normal examination, the Seattle Children’s screening pathway schedules the ultrasound at about 6 weeks. An abnormal examination would require a different, prompt assessment pathway.
• C. Breech presentation is a major risk factor, and a normal early exam doesn't rule out dysplasia.
• D. Ultrasound is the early screening study in this pathway; the follow-up AP pelvis radiograph is obtained at 6 months, not at this 2-week visit.

Takeaway: Breech infant with a normal hip examination: plan ultrasound at about 6 weeks and continue follow-up.

Correct answer: D. Don't give honey in any form until 12 months, because of the risk of infant botulism.

CDC advises that children younger than 12 months should not be given honey—not in food, water, or formula, and not on a pacifier—because it can cause botulism, a severe type of food poisoning.

Why the other choices are less suitable:

• A. CDC's advice not to give honey before 12 months makes no exception for pasteurized honey.
• B. CDC specifically advises against putting honey on a pacifier.
• C. The concern is botulism, not allergy.

Takeaway: No honey before 12 months: botulism risk.

Correct answer: C. Daily emollient plus a low- to mid-potency topical steroid twice daily on the flare until it improves.

The AAP's atopic dermatitis guidance addresses four targets together: moisturizing the skin, reducing itch, treating inflammation, and managing infection. For a flare, a topical corticosteroid is applied twice daily to affected areas until improvement—usually a few days to 2 to 3 weeks—using low potency, or mid potency if needed, in young children (away from the face), alongside daily emollients.

Why the other choices are less suitable:

• A. Systemic steroids aren't first-line for a mild flare in a young child.
• B. There is no sign of infection; the flare needs anti-inflammatory treatment.
• D. Moisturizer is the foundation, but an active flare also needs anti-inflammatory treatment.

Takeaway: Atopic dermatitis flare: daily emollient plus an age-appropriate topical steroid.

Correct answer: D. Get an exposure history, educate the family, report to the health department, and plan follow-up testing.

CDC uses a blood lead reference value of 3.5 µg/dL. For confirmed levels of 3.5 to 19 µg/dL, CDC recommends education about lead sources, reporting the result to the state or local health department, an environmental exposure history, attention to iron and calcium intake, developmental monitoring, and follow-up blood lead testing (early retests about every 3 months for levels up to 9). The reference value flags children with more lead than most children; it is not a safe threshold. CDC also advises checking for iron deficiency and arranging an environmental investigation as required; access to investigations varies by jurisdiction and resources.

Why the other choices are less suitable:

• A. CDC's blood lead reference value is 3.5 µg/dL, and 4.2 is above it.
• B. Chelation isn't part of CDC's recommended actions for levels of 3.5 to 19 µg/dL.
• C. CDC advises early follow-up testing—about 3 months for levels of 3.5 to 9 µg/dL.

Takeaway: Confirmed venous lead 3.5–19 µg/dL: exposure history, education, reporting, nutritional/developmental follow-up and repeat testing—not chelation.

Correct answer: A. Strongly consider peanut-specific IgE and/or skin prick testing, then plan early peanut introduction.

NIAID's addendum guidelines place infants with severe eczema, egg allergy, or both in the highest-risk group. For them, the guideline recommends introducing age-appropriate peanut-containing food as early as 4 to 6 months, after other solids show developmental readiness, and strongly considering peanut-specific IgE, skin prick testing, or both beforehand to decide whether and how to introduce it.

Why the other choices are less suitable:

• B. Delaying peanut doesn't prevent allergy; early introduction is recommended for this high-risk group.
• C. This skips the 4-to-6-month window recommended for high-risk infants.
• D. For infants with severe eczema or egg allergy, the guideline recommends strongly considering evaluation first.

Takeaway: Severe eczema or egg allergy: evaluate, then introduce peanut early (4–6 months).

Correct answer: C. Don't use codeine; use weight-based acetaminophen or ibuprofen instead.

In 2017 the FDA made codeine and tramadol contraindicated in children younger than 12 because of the risk of slowed or difficult breathing and death. Tramadol is also contraindicated under 18 for pain after tonsillectomy or adenoidectomy. Medicine prescribed for someone else shouldn't be used either.

Why the other choices are less suitable:

• A. Codeine is contraindicated under age 12 at any dose.
• B. Tramadol carries the same contraindication under age 12.
• D. The FDA contraindication applies to all children younger than 12.

Takeaway: Codeine and tramadol: contraindicated under 12.

Correct answer: C. Arrange immediate surgical (urologic) evaluation without waiting for imaging.

Testicular torsion is a clinical diagnosis. Classic findings are sudden, severe, one-sided pain, nausea and vomiting, a high-riding testis, and an absent cremasteric reflex. When the history and exam suggest torsion, immediate surgical exploration is indicated and should not be postponed for imaging. Delay can result in permanent injury and loss of the testis.

Why the other choices are less suitable:

• A. Sudden severe pain with these findings points to torsion, which must be excluded first.
• B. Waiting risks losing the testis; the salvage window is measured in hours.
• D. Symptom relief doesn't address possible torsion.

Takeaway: Suspected torsion: surgery now—don't wait for an ultrasound.

Correct answer: B. Use a qualified medical interpreter—in person, by phone, or by video—at no cost to the family.

Under the Section 1557 regulations (45 CFR 92.201), covered entities must offer a qualified interpreter free of charge. They may not require someone with limited English proficiency to bring their own interpreter, and may not rely on a minor child to interpret except as a temporary measure in an emergency involving an imminent threat to safety or welfare when no qualified interpreter is immediately available. This is a non-urgent visit.

Why the other choices are less suitable:

• A. A covered entity may rely on a minor child only as a temporary measure in an emergency.
• C. A covered entity can't require patients to supply their own interpreter.
• D. Staff who aren't qualified interpreters shouldn't be relied on to interpret.

Takeaway: Non-emergency visit: a qualified interpreter, never the child.

Correct answer: B. School first, then a supervised stepwise return to play; he won't be ready for Friday's game.

CDC's HEADS UP return-to-play progression has six steps, each typically taking at least 24 hours: back to regular activities such as school, light aerobic activity, moderate activity, heavy non-contact activity, full-contact practice, and then competition. The athlete moves forward only if no symptoms return, with a health care provider's approval. From Tuesday, there isn't time to complete it by Friday.

Why the other choices are less suitable:

• A. Being symptom-free starts the return-to-play process; it doesn't complete it.
• C. CDC's plan moves him back to regular activities such as school, not prolonged strict rest.
• D. Full-contact practice comes late in the progression, after light, moderate, and heavy non-contact steps.

Takeaway: School first, then a stepwise progression—each step at least 24 hours.

Correct answer: C. Low-dose ICS-formoterol in a single inhaler, used both daily and as needed (SMART).

The 2020 NAEPP focused update recommends single maintenance and reliever therapy (SMART) with ICS-formoterol for people 4 and older with moderate to severe persistent asthma. Stepping up from daily low-dose ICS, the preferred next step is low-dose ICS-formoterol used daily and as needed. Checking adherence, technique, and environment first—as was done here—comes before any step-up. This is a guideline-supported strategy, not a statement of U.S. reliever-use approval: the U.S. budesonide-formoterol product information does not indicate it for relief of acute bronchospasm, so its as-needed reliever use in SMART is off-label.

Why the other choices are less suitable:

• A. Adding a leukotriene receptor antagonist is an alternative, not the preferred step for ages 4 and older.
• B. Repeated systemic steroids aren't a controller strategy.
• D. Short-acting bronchodilators don't control the underlying inflammation.

Takeaway: Under NAEPP, age 4 or older stepping up from low-dose ICS: consider SMART with ICS-formoterol; reliever use is off-label under the U.S. product indication.

Correct answer: D. Screen him privately with a validated depression tool and a suicide-specific tool—for example, PHQ-9A plus the Ask Suicide-Screening Questions (ASQ).

The Bright Futures/AAP periodicity schedule includes depression and suicide-risk screening at annual visits beginning at age 12. A depression screen alone, including the PHQ-9 Modified for Adolescents (PHQ-9A), does not adequately identify all suicide risk. AAP describes pairing the PHQ-9A with a suicide-specific tool such as the Ask Suicide-Screening Questions (ASQ). Screen privately when possible, and follow a positive suicide screen with an appropriate safety assessment and response.

Why the other choices are less suitable:

• A. Screening at this age is routine, not symptom-driven.
• B. The periodicity schedule starts routine depression and suicide-risk screening at 12.
• C. Adolescent depression tools such as the PHQ-A are built on the teen's own answers.

Takeaway: At age 12 and older, screen for depression and suicide risk; do not substitute a depression-only tool for suicide-specific screening.

Correct answer: C. Give the other vaccines planned for today, but do not give rotavirus vaccine.

CDC lists a history of intussusception as a contraindication to rotavirus vaccine, along with severe combined immunodeficiency and a severe allergic reaction to a prior dose or vaccine component. It is not a contraindication to the other vaccines planned for this visit, so those go ahead as planned.

Why the other choices are less suitable:

• A. A history of intussusception is a contraindication to rotavirus vaccine, even after full recovery.
• B. Intussusception affects only the rotavirus decision; the other vaccines should stay on schedule.
• D. A normal ultrasound doesn't remove the contraindication.

Takeaway: Intussusception history rules out rotavirus vaccine only.

Correct answer: A. Oral polyethylene glycol (PEG) to clear the impaction, then daily maintenance PEG and toilet sitting.

The ESPGHAN/NASPGHAN guideline recommends oral PEG, 1 to 1.5 g/kg/day for 3 to 6 days, as first-line treatment for fecal impaction, followed by PEG as first-line maintenance (starting around 0.4 g/kg/day and adjusted to response). Maintenance continues for at least 2 months and until symptoms have been gone for at least 1 month. Behavioral steps such as scheduled toilet sitting support it.

Why the other choices are less suitable:

• B. Fiber doesn't clear an impaction; normal fiber and fluid intake supports treatment but isn't the treatment.
• C. Adding enemas to long-term treatment isn't recommended; PEG is first-line maintenance.
• D. Stimulant laxatives are considered only as additional or second-line options.

Takeaway: Clear the impaction with oral PEG, then maintain with PEG.

Correct answer: A. Tinea capitis.

Scaly patches of hair loss studded with broken-off hairs ('black dots') are a classic presentation of tinea capitis. Obtain appropriate fungal testing to confirm the diagnosis before treatment. Treatment requires an oral antifungal such as terbinafine or griseofulvin; topical creams alone are not adequate treatment for scalp ringworm.

Why the other choices are less suitable:

• B. Alopecia areata typically causes smooth patches without scale.
• C. Seborrheic dermatitis causes scale, but not patches of broken-off hairs.
• D. Traction hair loss follows tight hairstyles, usually along the hairline, without scale.

Takeaway: Scaly hair loss with black dots: think tinea capitis, which needs oral treatment.

Correct answer: C. Keep the seat rear-facing until the child reaches the seat's rear-facing height or weight limit.

NHTSA advises keeping children ages 1 to 3 rear-facing as long as possible, until they reach the top height or weight limit allowed by the car seat's manufacturer. Only then should they move to a forward-facing seat with a harness.

Why the other choices are less suitable:

• A. Age and weight rules of thumb don't decide this; NHTSA advises staying rear-facing as long as the seat allows.
• B. The seat's limits, not a birthday, decide when to switch.
• D. Boosters are for older children who have outgrown a forward-facing seat with a harness.

Takeaway: Rear-facing until the seat's rear-facing limit.

Correct answer: D. Topical mupirocin (or retapamulin) ointment applied to the lesions.

Limited nonbullous impetigo responds well to topical antibiotics such as mupirocin or retapamulin. The IDSA guideline recommends either agent twice daily for 5 days. Oral antibiotics active against staphylococci and streptococci are preferred for numerous lesions, ulceration into the dermis, or outbreaks.

Why the other choices are less suitable:

• A. Oral antibiotics are for numerous lesions, deeper infection, outbreaks, or failure of topical therapy.
• B. Honey-colored crusts point to impetigo, not herpes simplex.
• C. A steroid doesn't treat a bacterial skin infection.

Takeaway: Limited impetigo: topical antibiotic first.

Correct answer: B. Diagnose acute bacterial sinusitis clinically; no imaging is needed.

CDC’s pediatric outpatient guidance makes a clinical diagnosis of acute bacterial sinusitis when URI symptoms persist more than 10 days without improvement, worsen after initial improvement, or start severely (fever of at least 39 °C with purulent nasal discharge for 3 or more days). Clinicians should not order imaging to tell bacterial sinusitis from a viral URI. For persistent illness, CDC allows either antibiotics or 3 more days of observation.

Why the other choices are less suitable:

• A. Imaging doesn't distinguish bacterial sinusitis from a viral URI; CT is for suspected orbital or CNS complications.
• C. Plain films aren't recommended for this purpose either.
• D. Symptoms lasting more than 10 days without improvement meet the definition of persistent illness.

Takeaway: Pediatric sinusitis is a clinical diagnosis—no imaging unless complications are suspected.

Correct answer: C. Give intramuscular epinephrine with the auto-injector right away, then call 911.

Hives with throat tightness and coughing after a known allergen exposure signals anaphylaxis. AAAAI advises immediate epinephrine and emergency care, not waiting for collapse. Use the child's prescribed epinephrine autoinjector promptly and activate the school emergency plan. Antihistamines and bronchodilators such as albuterol are not substitutes for epinephrine.

• A. Antihistamines are add-on treatment and do not replace epinephrine.
• B. Bronchodilators are adjuncts; they don't treat anaphylaxis.
• D. Waiting for signs of shock delays the treatment that changes outcomes.

Takeaway: Anaphylaxis in this school scenario: use the prescribed epinephrine autoinjector immediately and call 911.

Correct answer: A. Arrange prompt evaluation for physical abuse and occult injury, including a skeletal survey, and make a suspected-abuse report under applicable state law.

An unexplained bruise in a non-mobile infant is a concerning possible sentinel injury. The infant needs prompt assessment for abuse and occult injury, not a watch-and-wait visit. The UCSF consensus guideline includes a skeletal survey and age-appropriate head-injury evaluation in very young infants when abuse is suspected. Consider medical causes of bruising as part of that assessment, but do not let a normal bleeding workup end the safety evaluation. Follow the applicable state's suspected-abuse reporting process.

Why the other choices are less suitable:

• B. Bruising in a non-mobile infant isn't expected and may be a sentinel injury.
• C. A bleeding workup may be part of the evaluation, but normal results don't replace an abuse evaluation.
• D. Waiting risks further, possibly more serious, injury.

Takeaway: Unexplained bruise in a non-mobile infant: prompt abuse and occult-injury evaluation, with reporting under applicable state law.

Correct answer: B. Screen the mother again at this visit.

The Bright Futures/AAP periodicity schedule includes maternal depression screening at the 1-, 2-, 4-, and 6-month visits. A negative screen at 1 month doesn't replace the 2-month screen.

Why the other choices are less suitable:

• A. Screening is also recommended at the 2- and 4-month visits.
• C. The schedule calls for routine screening at these visits, not symptom-triggered screening.
• D. The periodicity schedule includes maternal depression screening in the infant's well visits.

Takeaway: Maternal depression screening: 1-, 2-, 4-, and 6-month visits.

Correct answer: C. Give an injectable inactivated influenza vaccine instead.

CDC lists live attenuated influenza vaccine (LAIV, the nasal spray) as contraindicated in children 2 through 4 years old who have asthma or who have had wheezing in the past 12 months. An injectable inactivated influenza vaccine protects this child without that concern.

Why the other choices are less suitable:

• A. The contraindication is based on wheezing in the past 12 months, not on today's exam.
• B. The family wants the child vaccinated and nothing rules that out; only the live nasal product is the problem.
• D. Pretreatment does not remove the contraindication.

Takeaway: Ages 2–4 with wheezing in the past 12 months: use injectable flu vaccine, not LAIV.

Correct answer: D. Permethrin 5% cream for the child, with repeat treatment about 1 week later as directed, and simultaneous age-appropriate treatment of household members and close contacts.

Permethrin 5% cream is an appropriate treatment for this 6-year-old. CDC advises applying prescribed scabicide to the entire head, neck, and body in children; follow the clinician's directions and avoid the eyes and mouth. Permethrin is washed off after 8 to 14 hours, and a repeat application about a week later may be needed. Everyone in the household and other close contacts should be treated at the same time, even if they have no rash, using a regimen appropriate for their age and circumstances. Itching can last several weeks after successful treatment and doesn't by itself mean treatment failed.

Why the other choices are less suitable:

• A. Contacts can be infested before symptoms appear; treating everyone at once prevents reinfestation.
• B. Antihistamines ease itching but don't kill mites.
• C. Steroids can help itching after treatment, but they don't treat the infestation.

Takeaway: Scabies: treat the patient and all close contacts at the same time.

Correct answer: D. Abdominal (pyloric) ultrasound.

Forceful nonbilious vomiting right after feeds in a hungry, weight-losing infant a few weeks old suggests hypertrophic pyloric stenosis. The Royal Children's Hospital guideline recommends abdominal ultrasound for this suspected diagnosis. Ultrasound shows the pylorus directly and uses no radiation. An early equivocal study may need repeating if clinical suspicion remains.

Why the other choices are less suitable:

• A. Ultrasound is preferred first because it shows the pyloric muscle directly without radiation.
• B. Progressive projectile vomiting with weight loss needs evaluation for pyloric stenosis.
• C. CT adds radiation and isn't a first-line study for this question.

Takeaway: Suspected pyloric stenosis: ultrasound first.

Correct answer: C. Store the firearm unloaded and locked, with ammunition locked separately.

CDC recommends secure storage to prevent unauthorized access: keep firearms unloaded and locked, with ammunition stored securely separately. A hiding place or verbal warning is not a substitute for preventing access. Safer-storage counseling is part of anticipatory guidance.

Why the other choices are less suitable:

• A. Education alone doesn't stop curious children from handling a gun they find.
• B. A hidden, loaded gun is still accessible and isn't safe storage.
• D. A loaded gun does not follow the unloaded, locked, separate-ammunition storage guidance.

Takeaway: Store firearms unloaded and locked, with ammunition locked separately.

Correct answer: B. Parent training in behavior management, plus behavioral classroom interventions if available.

The AAP's 2019 ADHD guideline recommends evidence-based parent training in behavior management and/or behavioral classroom interventions as first-line treatment for children 4 to 5 years old, with medication an option in certain circumstances. CDC notes that parent training has been shown to work as well as medication in young children, who also have more side effects from ADHD medications.

Why the other choices are less suitable:

• A. For children younger than 6, behavioral treatment comes first; medication may be considered in certain circumstances later.
• C. Medication isn't first-line at this age.
• D. Treatment shouldn't wait; effective behavioral treatment is available now.

Takeaway: Preschool ADHD: parent training in behavior management first.

Correct answer: D. Bilateral AP and frog-leg lateral hip radiographs, no weight-bearing, and urgent orthopedic referral.

Slipped capital femoral epiphysis (SCFE) is an adolescent hip disorder that can be missed because pain may be felt in the thigh or knee. Obesity is a risk factor. Diagnosis is confirmed with bilateral hip radiographs, including AP and frog-leg views when the slip is stable. Because delay can cause lasting hip damage, the child should stop weight-bearing and be referred urgently.

Why the other choices are less suitable:

• A. Hip disease often causes referred knee pain; imaging only the knee can miss it.
• B. The hip findings point to slipped capital femoral epiphysis, which must be ruled out.
• C. The knee exam is normal; the hip is the problem.

Takeaway: Knee pain and a limp in an adolescent: examine and image both hips.

Correct answer: D. Vitamin D 400 IU by mouth every day, starting now.

CDC notes that breast milk alone does not give infants enough vitamin D. The Dietary Guidelines for Americans and the AAP recommend 400 IU of vitamin D daily for breastfed and partially breastfed infants, beginning in the first few days of life.

Why the other choices are less suitable:

• A. Breast milk alone doesn't provide enough vitamin D.
• B. Supplementation should start in the first days of life, not months later.
• C. The recommendation for breastfed infants doesn't depend on sun exposure.

Takeaway: Breastfed infants: vitamin D 400 IU daily from the first days of life.

Correct answer: B. 6

Number needed to treat (NNT) = 1 ÷ absolute risk reduction. The absolute reduction is (268 − 94) per 1,000, or 0.174. 1 ÷ 0.174 = 5.75, which is conventionally rounded up to 6 people for this calculation. The hypothetical outcome here is avoiding one first-attempt failure; it is not a comparison of long-term outcomes.

Why the other choices are less suitable:

• A. That is 1 ÷ 0.268—the inverse of the technique A failure rate, not of the difference.
• C. That is 1 ÷ 0.094—the inverse of technique B's failure rate, not the inverse of the absolute reduction.
• D. That is the absolute reduction per 1,000 children, not the number needed to treat.

Takeaway: NNT = 1 ÷ absolute risk reduction, rounded up.

Correct answer: B. Karyotype.

In a girl, short stature with falling height percentiles, absent pubertal development, and features such as a low posterior hairline and widely spaced nipples should prompt evaluation for Turner syndrome. The diagnosis is made by chromosome analysis (karyotype), as described by NICHD. The Pediatric Endocrine Society identifies no breast development by age 13 as a delayed-puberty finding.

Why the other choices are less suitable:

• A. Falling height percentiles, absent puberty, and these physical features call for testing for Turner syndrome, not reassurance.
• C. Turner syndrome should be diagnosed or excluded first; stimulation testing isn't the first study here.
• D. Hypothyroidism can slow growth, but it doesn't explain this combination of findings on its own.

Takeaway: Girl with growth failure and delayed puberty: get a karyotype.

Correct answer: C. Refer promptly to a hemangioma specialist, ideally by 1 month of age.

The AAP's 2019 guideline classifies hemangiomas with potential for functional impairment—such as periorbital lesions—as high risk. Because the most rapid growth happens between 1 and 3 months, it recommends early consultation, ideally by 1 month of age, and evaluation by a hemangioma specialist as soon as possible. Oral propranolol is first-line when systemic treatment is needed.

Why the other choices are less suitable:

• A. Most do, but a periocular hemangioma is high risk because it can threaten vision.
• B. The fastest growth happens between 1 and 3 months; waiting misses the treatment window.
• D. Imaging isn't needed unless the diagnosis is uncertain, there are 5 or more skin hemangiomas, or associated anomalies are suspected.

Takeaway: Periocular hemangioma is high risk: refer by 1 month.

Correct answer: D. Give the vaccines that are due today.

CDC lists mild acute illness with or without fever, and current antimicrobial therapy, among conditions incorrectly perceived as contraindications. Moderate or severe acute illness is a precaution, but a playful toddler who is eating well with a low-grade fever doesn't fit that picture. Delaying turns the visit into a missed opportunity.

Why the other choices are less suitable:

• A. Taking an antibiotic such as amoxicillin is not a contraindication to routine vaccines.
• B. Mild illness with a low-grade fever is not a reason to delay.
• C. Amoxicillin and a mild illness don't change eligibility for the live viral vaccines due at this age.

Takeaway: Mild illness, low-grade fever, and antibiotics are not reasons to delay vaccines; moderate or severe illness is a precaution.

Correct answer: D. Use instrument-based vision screening.

The periodicity schedule notes that instrument-based screening may be used to assess vision risk at 12 and 24 months and at the 3- through 5-year visits. It is a practical option for a child who can't yet complete chart (optotype) testing.

Why the other choices are less suitable:

• A. Vision screening is due at 3 years, and instrument-based screening is an option now.
• B. Instrument-based screening can be done first in primary care.
• C. A red reflex check doesn't substitute for vision screening at this age.

Takeaway: Can't do the chart at 3? Use instrument-based screening.

Correct answer: A. Go to the emergency department now for an X-ray; if honey is available, give 10 mL every 10 minutes on the way, up to 6 doses, without delaying travel.

The National Capital Poison Center guideline calls for urgent evaluation in this child's situation: don't induce vomiting, get an X-ray right away to locate the battery, and remove it urgently if it's in the esophagus. For children 12 months or older who can swallow, when a lithium coin cell may have been swallowed within the past 12 hours, 10 mL of honey every 10 minutes (up to 6 doses) on the way can reduce injury—without delaying the trip. (Honey is not used in infants younger than 12 months.)

Why the other choices are less suitable:

• B. A battery lodged in the esophagus can cause serious injury quickly, even when the child seems fine.
• C. The poison center guideline says not to induce vomiting.
• D. Waiting for symptoms delays finding and removing a battery that may be in the esophagus.

Takeaway: Suspected button battery in this toddler: emergency evaluation now; honey only if age >=12 months, ingestion <12 hours ago, and able to swallow—10 mL every 10 minutes, up to 6 doses, without delay.

Correct answer: C. Levonorgestrel 1.5 mg is sold over the counter with no age limit; take it as soon as possible.

The FDA approved levonorgestrel 1.5 mg (Plan B One-Step) for nonprescription use without age restrictions on June 20, 2013. It is a backup method, labeled to be taken as soon as possible within 3 days after unprotected sex. The visit is also a chance to talk about ongoing contraception and STI testing.

Why the other choices are less suitable:

• A. That age restriction was removed in 2013.
• B. It is labeled for use as soon as possible within 3 days; sooner is better.
• D. Over-the-counter sale has no age or point-of-sale restriction.

Takeaway: Levonorgestrel emergency contraception: over the counter, no age limit, take as soon as possible.

Correct answer: D. Repeated urinalysis and blood pressure checks to detect kidney involvement.

Palpable purpura on the buttocks and legs with a normal platelet count, plus abdominal pain and arthritis, fits IgA vasculitis (Henoch-Schönlein purpura), the most common vasculitis of childhood. Kidney involvement can appear weeks or months after the rash, so blood pressure and urine are checked several times during the illness and again about 6 months after it resolves.

Why the other choices are less suitable:

• A. The platelet count is normal; the purpura comes from vasculitis, not thrombocytopenia.
• B. Normal platelets and this classic pattern don't point to a marrow disorder.
• C. He is afebrile and well, and the rash distribution with joint and abdominal findings fits IgA vasculitis.

Takeaway: IgA vasculitis: follow urine and blood pressure for months.

Correct answer: C. Refer to a pediatric urologist or surgeon now.

A testis that has not descended by 6 months, corrected for gestational age, needs timely surgical-specialist evaluation. The European Association of Urology guideline explains that spontaneous descent after that age is unlikely and routine localizing imaging has limited value. It recommends surgery within the subsequent year, preferably by 12 months and no later than 18 months. Do not delay this referral for an ultrasound.

Why the other choices are less suitable:

• A. Routine localizing ultrasound does not reliably settle whether or where an undescended testis is present and should not delay specialist evaluation.
• B. Descent is unlikely after 6 months, and referral is due now.
• D. The EAU guideline does not recommend hormonal therapy solely to induce descent in a unilateral undescended testis.

Takeaway: Undescended testis at 6 months: refer—no ultrasound first.

Correct answer: D. Give varicella vaccine once at least 28 days have passed since the MMR dose.

Live injectable vaccines such as MMR and varicella can be given at the same visit. If they aren't, CDC advises waiting at least 28 days (4 weeks) before giving the second one. This child can receive varicella vaccine 12 days from now.

Why the other choices are less suitable:

• A. Live injectable vaccines not given on the same day need at least 28 days between them; only 16 days have passed.
• B. That repeats measles, mumps, and rubella vaccine too soon and still gives varicella inside the 28-day window.
• C. Waiting that long isn't necessary; the minimum spacing is 28 days.

Takeaway: MMR and varicella: same day, or at least 28 days apart.

Correct answer: B. Screen for anxiety with a validated tool, such as the SCARED.

In 2022 the USPSTF recommended screening for anxiety in children and adolescents ages 8 to 18 (grade B), including those without recognized signs or symptoms. For children 7 and younger, it found the evidence insufficient.

Why the other choices are less suitable:

• A. USPSTF recommends anxiety screening starting at age 8.
• C. The recommendation covers all youth 8 to 18 without symptoms, not just those with risk factors.
• D. Routine depression screening begins at 12; at 9, anxiety screening is the recommended one.

Takeaway: Anxiety screening: ages 8 to 18.

Correct answer: B. 5 mL twice daily.

Dose: 16 kg × 25 mg/kg = 400 mg per dose, which is under the 500 mg maximum. Concentration: 400 mg ÷ 5 mL = 80 mg/mL. Volume: 400 mg ÷ 80 mg/mL = 5 mL per dose, twice daily for 10 days. CDC lists this regimen (25 mg/kg twice daily, maximum 500 mg per dose) as an alternative to 50 mg/kg once daily.

Why the other choices are less suitable:

• A. That delivers 200 mg per dose—half the intended 400 mg.
• C. That delivers 800 mg per dose—the whole daily amount at each dose, and above the 500 mg maximum.
• D. That comes from misreading the concentration as 100 mg/5 mL (20 mg/mL); it would deliver 1,600 mg per dose.

Takeaway: Work it step by step—mg/kg to mg per dose, mg/mL, then mL—and check the maximum.

Correct answer: D. Discuss the infant’s iron needs and supplementation plan now, and plan iron-rich complementary foods at about 6 months.

CDC advises discussing a breastfed infant’s iron needs and supplementation with the healthcare provider during the first 6 months. By about 6 months, an external source of iron is needed, including iron-rich complementary foods and, when indicated, iron supplementation. This healthy infant’s preventive nutrition plan does not require waiting for anemia to develop or replacing breast milk with cow’s milk.

Why the other choices are less suitable:

• A. By about 6 months, infants need an iron source outside breast milk; waiting until 12 months leaves that need unaddressed.
• B. Supplementation here is preventive, so it doesn't wait for abnormal lab results.
• C. Cow's milk (or plant-based milk) shouldn't be offered in place of human milk or formula before 12 months.

Takeaway: For a breastfed infant, plan iron intake before 6 months and add iron-rich complementary foods at about 6 months.

Correct answer: B. Look for the source of the fever; no routine LP, EEG, blood tests, or neuroimaging solely because of the simple febrile seizure.

This is a simple febrile seizure: brief, generalized, not repeated, and followed by recovery in a developmentally normal child. Evaluation should focus on finding the cause of the fever. The Royal Children’s Hospital guideline does not recommend extra investigations for a simple febrile seizure beyond those needed for the febrile illness. Signs of meningitis, incomplete recovery, focal features, or other concerning findings change the assessment.

Why the other choices are less suitable:

• A. EEG is not part of the routine evaluation of a simple febrile seizure in this otherwise well child.
• C. Neuroimaging isn't recommended for a simple febrile seizure.
• D. A lumbar puncture isn't routine in a well-appearing, fully immunized child without meningeal signs.

Takeaway: Simple febrile seizure: assess the fever source; do not order routine seizure tests, but investigate the febrile illness as indicated.

Correct answer: C. No removal is needed, since the wax causes no symptoms and doesn't block the exam.

The AAO-HNSF cerumen guideline defines impaction as cerumen that causes symptoms or keeps the clinician from examining the ear. Removal shouldn't be routine when there are no symptoms and the ears can be evaluated. When removal is needed, options include cerumenolytic drops, irrigation, or manual removal; ear candling is not recommended.

Why the other choices are less suitable:

• A. Treatment isn't recommended when there are no symptoms and the ears can be examined.
• B. Putting objects into the canal can push wax deeper or injure the canal.
• D. The guideline recommends against ear candling.

Takeaway: Asymptomatic wax that doesn't block the view: leave it.

Correct answer: B. A 4-foot, four-sided fence separating the pool from the house and yard, with a self-closing, self-latching gate.

CDC recommends a four-sided fence at least 4 feet high that separates the pool from the house, with a self-closing, self-latching gate. Swimming lessons and alarms do not replace that barrier. Close, constant adult supervision remains necessary whenever children are in or near the water.

Why the other choices are less suitable:

• A. Lessons don't replace a barrier for a 3-year-old.
• C. Using the house as one side leaves direct access from the home to the pool.
• D. Alarms and covers can add layers of protection, but they don't replace a four-sided fence.

Correct answer: B. A standardized general developmental screen, such as the Ages & Stages Questionnaire.

The periodicity schedule calls for standardized developmental screening at 9, 18, and 30 months and autism-specific screening at 18 and 24 months, with developmental surveillance at every visit. A negative autism screen doesn't replace the 30-month general screen.

Why the other choices are less suitable:

• A. Surveillance continues at every visit, but a standardized screen is also due at 30 months.
• C. Autism-specific screening is scheduled at 18 and 24 months; 30 months calls for general developmental screening.
• D. The 30-month visit is one of the scheduled general screening visits.

Correct answer: A. Start now: introduce the transition policy, then build self-care skills and a plan; transfer is usually at 18–21.

Got Transition's Six Core Elements, which put the 2018 AAP/AAFP/ACP clinical report into practice, lay out a timeline: share and discuss a transition policy at ages 12 to 14; track progress, assess self-care skills, and develop a transition plan with a medical summary from 14 to 18; transfer to adult care at 18 to 21; and then confirm the transfer is complete.

Why the other choices are less suitable:

• B. Preparation should begin in early adolescence, well before transfer.
• C. That leaves little time to build self-management skills.
• D. Transition planning doesn't depend on a lab target.

Correct answer: A. You may send the records for the pulmonologist's treatment of him without his written authorization.

HIPAA's Privacy Rule (45 CFR 164.506) lets a covered entity use or disclose protected health information for treatment without the individual's authorization, including disclosure for the treatment activities of any health care provider. The details in the stem matter: psychotherapy notes have separate authorization rules and limited exceptions, and agreed-to restrictions, substance use treatment records, or stricter state laws can change the answer.

Why the other choices are less suitable:

• B. Disclosures between providers for treatment are permitted without an authorization.
• C. Being a patient since childhood does not create a parental-authorization requirement for this provider-to-provider treatment disclosure under HIPAA.
• D. HIPAA permits disclosure for the treatment activities of any health care provider.

Correct answer: D. Screen with a standardized tool and examine him today, and refer now for evaluation and early intervention.

CDC lists walking without holding on to anyone or anything as an 18-month milestone—something at least 75% of children do by that age. When a milestone is missed, CDC advises acting early: developmental screening, referral for further evaluation, and contact with the state's early intervention program. The 18-month visit is also a scheduled standardized developmental screening visit.

Why the other choices are less suitable:

• A. Not walking independently by 18 months is a missed milestone that warrants action now.
• B. Shoes don't treat a motor delay, and waiting delays services.
• C. CDC advises acting early when a milestone is missed rather than waiting.
