VTNE Exam Prep: Free Study Guide

Start your VTNE exam prep with 25 original, unofficial questions written by Castleport Test Prep, not real VTNE items. Your score here is feedback on 25 questions, not a VTNE score or a prediction.

25 free VTNE practice questions

These questions use the VTNE's format of four options with one best answer. The set is weighted roughly like the exam: 5 Animal Care, 3 each for Pharmacy, Surgical Nursing, and Anesthesia, and 2 each for the six smaller domains except Communication, which gets 1.

Done? Count your correct answers by domain. If you stop early, record how many you answered and how many of those were correct. A miss in a 2-question domain tells you to look closer at that topic. It doesn't measure the whole domain. Pick two topics you missed or guessed and add them to the error log below.

Turn missed questions into your next study session

Write down why you chose a wrong answer. "Didn't know it," "unit error," "misread the question," and "guessed" each need a different fix.

Two rules make this work:

• Revisit later without the answer showing. If you can explain why the right answer is right and why the others are wrong, you've demonstrated the reasoning for that item. If you only remember the letter, you haven't. Recheck the topic later with a new question or example.
• Re-learn, don't just re-quiz. A question bank tells you what you missed. A textbook chapter or guideline teaches it back to you. Do both.

Your 6-week VTNE study plan

Time assumption: five 60-minute sessions plus one 2-hour block a week. That's 7 hours a week, 42 hours total, with one day off or kept for catch-up. This is our editorial plan, not an AAVSB requirement, and six weeks isn't guaranteed to be enough for everyone. If you've been out of school a while, stretch it (see below).

Every 60-minute session: 10 minutes recalling the topic from memory before you open anything, 25 minutes of focused review, 20 minutes of questions or worked problems, and 5 minutes updating your error log. Use 10–15 minutes of the 20-minute questions or worked-problems block for math on most days.

The weekly 2-hour block: mixed questions across everything you've covered so far, then checking your reasoning against sources, then planning next week.

Your first 35-minute study session

1. 25 minutes: Answer the 25 practice questions above without notes. Mark any you guessed, even if you got them right.
2. 10 minutes: Begin reviewing the explanations for missed or guessed questions; continue in your next session if needed. Write two topics in the error log to start this week's study.

That's it. You now know where to begin, and the 6-week plan tells you what to do next.

For the timed blocks, the 25 questions on this page take about 27 minutes at the exam's average pace; use the rest of the 2-hour block to check reasoning, revisit review points, and plan next week. Repeating familiar questions practices recall, so a higher repeat score is not a fresh readiness measure. A timed mixed set from your existing course materials works too.

If you have less time, more time, or only two weeks

• Fewer hours a week: Split each 60-minute session into two 30-minute sessions, and stretch the plan across more weeks if your exam date allows. If the date is fixed, focus on the misses in your error log and accept that you'll cover less depth.
• More than six weeks: Repeat the repair-and-mix approach from Week 6 with new questions, and keep the final week for light review and logistics.
• Two weeks left:

Retaking the VTNE

You can retake no sooner than 31 days after your last attempt. Each retake means a new application and the full fee, and you're limited to three attempts per calendar year (handbook, pp. 14 and 26). The next attempt also depends on approved eligibility, any required board approval, the application cutoff, a testing window, and an available appointment. A workable first 30 days of study:

• Days 1–3: write down the broad topics and study skills that felt hardest, without reconstructing exam questions, then take the 25 questions here.
• Days 4–24: use the topics in Weeks 1–5 to plan three weeks of review, biggest domains and worst misses first.
• Days 25–30: timed practice and logistics.

If you studied mainly with a question bank last time, add textbook re-learning. Retake limits are stricter in some places. AAVSB requires Board review and approval before attempts beyond five, counting attempts since January 1, 2006 (AAVSB retake rules). In Tennessee, an unsuccessful candidate's application file closes after the opportunity for three VTNE attempts; a new application and fees are required before further board action (Tennessee rules, 1730-03-.07(3)–(4), p. 8). Missouri won't accept a fifth attempt or beyond; before a fourth, you must appear before the board and complete a board-approved continuing-education program (20 CSR 2270-3.020(6), printed p. 3). Check your own state or provincial board for its additional conditions.

VTNE math, worked step by step

Pharmacy calculations, fluid therapy rates, and applied math all appear in the official content outline. The exam gives you an on-screen calculator, not your own. Write the units on every line, and they'll tell you when you've gone wrong. All numbers below are practice inputs, not dosing recommendations.

1. Weight → amount → volume. A 33-lb dog has an order for 4 mg/kg. The solution is 10 mg/mL. Use 1 kg = 2.2 lb. 33 lb ÷ 2.2 = 15 kg → 15 kg × 4 mg/kg = 60 mg → 60 mg ÷ 10 mg/mL = 6 mL. mg/kg × kg gives mg. mg ÷ (mg/mL) gives mL.

2. Percent solutions. A percent (w/v) solution means grams per 100 mL, so 1% = 10 mg/mL (e-SAFE Anaesthesia). An 8-kg dog has an order for 5 mg/kg of a 2.5% w/v solution. 2.5% = 25 mg/mL → 8 kg × 5 mg/kg = 40 mg → 40 mg ÷ 25 mg/mL = 1.6 mL.

3. Fluid deficit. AAHA's 2024 fluid therapy guidelines give: fluid deficit (L) = body weight (kg) × % dehydration as a decimal (AAHA, Box 3). A veterinarian estimates a 12-kg dog at 6% dehydrated. 12 × 0.06 = 0.72 L = 720 mL. That's the estimated deficit volume, not an hourly rate. Maintenance needs and ongoing losses are added separately in a real fluid plan.

4. Drip rate. Drops per minute = mL per hour × drops per mL ÷ 60. An order is 12 mL/h through a 60 drops/mL microdrip set. 12 × 60 ÷ 60 = 12 drops/min. With a 60-drop set, drops per minute always equals mL per hour, which is a handy check.

5. Constant rate infusion (CRI) added to a fluid bag. A 10-kg dog has an order for 0.1 mg/kg/h of a drug added to fluids running at 50 mL/h. The stock is 10 mg/mL. For this calculation, the final mixed volume, including the drug, is exactly 1 L. Drug per hour: 0.1 × 10 = 1 mg/h. One liter lasts 1,000 ÷ 50 = 20 h, so the bag needs 1 mg/h × 20 h = 20 mg. Volume to add: 20 mg ÷ 10 mg/mL = 2 mL.

Sanity check every answer. Recheck the weight conversion, prescribed amount, concentration, and units; tablet count depends on tablet strength as well as the prescribed dose.

What to review in each VTNE domain

The Veterinary Technician National Examination (VTNE) has 170 questions in 3 hours. 150 of them are scored, across 10 domains, and a scaled score of 425 passes (AAVSB handbook, pp. 7 and 29). Put your time where the questions are.

Source: AAVSB VTNE Content Outline (PDF, p. 1), content outline approved March 2023. Percentages are AAVSB's rounded figures.

Four domains (Animal Care, Pharmacy, Surgical Nursing, and Anesthesia) make up 90 of the 150 scored questions, or exactly 60%. Still, your own misses matter more than the averages. If you miss every dentistry question, dentistry moves up your list.

Each domain below lists what the content outline's task statements ask you to do, then a few points worth knowing cold. The points are examples to anchor your review, not the whole domain.

The VTNE isn't a dogs-and-cats-only exam. AAVSB says the species covered are those in the AVMA's essential and recommended skills list for accredited programs (AAVSB study page). Review horses, food animals, lab animals, and exotics along with companion animals; those groups also appear in the AAVSB-linked CVMA essential and recommended tasks list.

Animal Care and Nursing (30 questions)

The tasks: assess and document patients, perform nursing procedures, take blood pressure, ECG, and tonometry, give medications by the right route, collect specimens, and handle and restrain safely.

• Blood pressure: For Doppler measurement, use a cuff width about 30–40% of the limb circumference. Let the patient settle 5–10 minutes, discard the first reading, and average 5–7 consistent readings (ACVIM 2018). In that statement's risk categories, 160–179 mmHg systolic is hypertensive and 180 or above is severely hypertensive.
• Specimens: For dogs, cystocentesis is the preferred urine collection for culture (Merck). For routine canine hematology, EDTA (purple top) is preferred, and heparin causes clumping and staining artifacts (eClinpath).
• Feline vaccine sites: In the supported distal-limb pattern, rabies goes below the right stifle and FeLV below the left; the guidelines allow medically appropriate practitioner discretion. Avoid the area between the shoulder blades (AAHA/AAFP 2020).
• Species: An adult cow's stomach has four compartments: rumen, reticulum, omasum, and abomasum. The rumen is the fermentation vat, and the abomasum is the glandular "true" stomach (UMN Extension). Horses have a simple stomach and a hindgut that handles fiber digestion (UMN Extension). To lift a rabbit, support the chest and the hind end, hold it close, and stay near the floor (University of Illinois CVM).

Common trap: Rushing BP technique questions. The protocol details are the answer.

Pharmacy and Pharmacology (20 questions)

The tasks: prepare and dispense to the veterinarian's orders, calculate doses, fluid rates, and CRIs, recognize drug classes and side effects, keep controlled-drug logs, and store and dispose of drugs safely.

• U.S. schedules for common veterinary drugs: Hydromorphone is Schedule II. Ketamine and buprenorphine are Schedule III. Butorphanol, diazepam, midazolam, phenobarbital, and tramadol are Schedule IV (21 CFR Part 1308).
• Ordering: A DEA-registered practice purchasing Schedule II clinic stock from a supplier uses DEA Form 222 or the electronic version, CSOS (21 CFR 1305.03).
• Records: Controlled-substance records are kept at least 2 years (21 CFR 1304.04).
• Theft or significant loss: The DEA registrant must send written notice to the DEA Field Division Office within one business day of discovery, then file DEA Form 106 within 45 days of discovery (21 CFR 1301.76(b)). These are federal rules; states can be stricter. Canadian candidates follow Canada's controlled-drug regulations, which AAVSB also lists as references.

Common trap: Mixing up mg, mg/kg, and mL. See the math section.

Surgical Nursing (20 questions)

The tasks: prepare the room, instruments, and patient, work as a sterile or circulating technician, keep conditions aseptic, and clean and sterilize equipment.

• Monitoring sterilization: Biological indicators with Geobacillus stearothermophilus spores test steam-sterilization kill. Chemical indicators only show exposure to the process (CDC).
• Ethylene oxide: EO-sterilized items need completed aeration to remove residual gas; finishing the exposure phase alone is not enough (CDC).
• Damaged packs: A pack that's wet, torn, punctured, or damaged gets pulled, repackaged, and reprocessed (University of Michigan).

Common trap: Treating a color-changed indicator as proof of sterility.

Anesthesia (20 questions)

The tasks: help build the anesthetic plan, prepare and maintain equipment, intubate, and monitor and respond before, during, and after anesthesia.

• Ventilation (ETCO2): about 35–45 mmHg awake, and about 40–50 (up to 55) acceptable at a surgical plane. Above 60 mmHg is hypercapnia; report it to the veterinarian and assess the cause (AAHA 2020, p. 19).
• Oxygenation (SpO2): With a reliable reading, below 95% is hypoxemia, and below 90% is severe.
• Match each monitor to what it tells you: capnography for ventilation, pulse oximetry for oxygenation, ECG for heart rhythm, and temperature for thermal status. One normal number doesn't mean every system is fine (AAHA monitoring guidance).

Common trap: Mixing up ventilation (CO2) and oxygenation (O2).

Laboratory Procedures (14 questions)

The tasks: prepare and handle samples, run microbiology, serology, cytology, hematology, urinalysis, and parasitology, and keep equipment quality-controlled.

• Platelet clumps falsely lower analyzer platelet counts, so check the smear (eClinpath).
• New methylene blue precipitates RNA so reticulocytes can be identified (eClinpath).
• Urine specific gravity: Isosthenuria is 1.008–1.012. Interpret concentration with hydration status and other findings; the number alone does not diagnose kidney disease (eClinpath).

Common trap: Trusting the machine number without checking the sample.

Dentistry (10 questions)

The tasks: dental anatomy, setting up equipment, the comprehensive oral health assessment and treatment (COHAT), and dental radiographs.

• Modified Triadan quadrants: 1 = right maxillary, 2 = left maxillary, 3 = left mandibular, 4 = right mandibular. Deciduous teeth use 5–8. Canines are always 04 and first molars 09 (AVDC).
• Tooth counts: Adult dogs have 42 permanent teeth (Merck) and adult cats have 30 (Iowa State CVM).
• Awake exams underestimate disease. Probing and intraoral radiographs under anesthesia show the full picture, and probing should never be done on an awake patient (AAHA 2019).

Common trap: Swapping 104 and 204. Quadrant 1 is the patient's right maxilla.

Emergency Medicine/Critical Care (10 questions)

The tasks: triage for shock, trauma, and toxicity, perform CPR, control bleeding, stabilize fractures, and assist with transfusion, fluid resuscitation, and oxygen therapy.

• CPR (RECOVER 2024):
  • 100–120 compressions per minute
  • In intubated dogs and cats, use uninterrupted 2-minute compression cycles
  • For dogs and cats in lateral recumbency, compress one-third to one-half of the chest's width at the compression point
  • Intubated patients are ventilated at 10 breaths per minute
• Xylitol causes a rapid insulin release in dogs, which can lead to profound hypoglycemia, and some dogs develop severe liver injury (Merck).

Common trap: Confusing the compression rate with the breathing rate.

Pain Management/Analgesia (10 questions)

The tasks: recognize when a patient needs analgesia, and help build and carry out the pain plan.

• Quiet doesn't mean comfortable. Calm behavior and poor appetite can be subtle signs of pain in dogs (AAHA 2022).
• Scale validity, per AAHA 2022: The Feline Grimace Scale and the UNESP-Botucatu scale are rated valid for cats. The Glasgow short form is moderately validated for dogs. The Colorado State scales are listed as not validated (AAHA 2022 PDF, Tables 1–2).

Common trap: Assuming no vocalizing means no pain.

Diagnostic Imaging (9 questions)

The tasks: produce and document diagnostic images safely, and maintain equipment.

• Inverse square law: For a constant-output point source, ignoring absorption and scatter, double the distance and the intensity drops to one-fourth (IAEA, pp. 30–31).
• Keep body parts out of the primary beam, even when shielded. In the study, fully enclosing gloves cut scatter far more than open-palm shields (Mayer et al. 2019).

Common trap: Thinking a lead glove makes the primary beam safe.

Communication and Veterinary Professional Support Services (7 questions)

The tasks: educate clients (including about zoonoses), communicate professionally, take histories, and support the euthanasia process.

• Toxoplasmosis: Change litter daily, because the parasite takes 1–5 days to become infectious. Pregnant clients should have someone else change it, or wear gloves and wash their hands. Cat owners don't have to give up their cat (CDC, CDC handout).
• Open-ended inquiry and reflective listening (paraphrasing what the client said back to them) are core client-communication skills (AAHA 2026). "What part of the plan seems hard to manage at home?" uncovers more than "Do you understand?"
• Professional ethics, including the Veterinary Technician Code of Ethics, is one of the outline's knowledge areas (handbook, p. 40). NAVTA publishes its code on its policies page.

Common trap: Reassuring a client instead of finding out what's actually worrying them.

Applying, testing windows, and fees

The VTNE runs in four testing windows a year. Finish your application by the cutoff, and apply early: AAVSB's eligibility review can take up to two weeks once all documents are received.

As of October 17, 2026, the next window is November 15, 2026 – January 15, 2027, with a December 15, 2026 completed-application cutoff.

• Fee: $375, nonrefundable. You can move once to the very next window for $90, requesting the transfer at least 48 hours before a booked appointment or before the current window ends if you have not booked. An unexcused missed appointment forfeits the fee; contact AAVSB immediately about a documented excused absence.
• Eligibility pathways:
  • Accredited programs (AVMA-CVTEA or CVMA): this is the accredited-education pathway, with AAVSB confirming eligibility for your selected jurisdiction. Under the current roster process, your program director must upload you on a roster before you can test. Some programs let students test in their last semester; graduates outside the roster process should follow the transcript instructions on the official pathway page.
  • On-the-job training: available only in participating jurisdictions.
  • Alternate pathways: accepted in select jurisdictions.

Taking the VTNE through on-the-job training or an alternate pathway can limit where you become licensed later; another jurisdiction may not recognize that pathway (AAVSB pathway guidance).

• Credentialing: AAVSB runs the exam and sends your score, but it doesn't license anyone. Your state or provincial board grants the credential. Find yours with the AAVSB board lookup.

If you need testing accommodations, follow the AAVSB application instructions early, before scheduling.

Official study resources worth using

• VTNE content outline (PDF): your checklist of every task and knowledge area.
• AAVSB study page: links to 10 free sample questions, a common-abbreviations list, and the reference list. The older sample PDF uses an outdated domain map; use the current content outline for today's domains.
• AAVSB reference list (PDF, updated April 2026): use this index to match topics to reference materials you already have.
• Free web references on that list: the RECOVER CPR guidelines, eClinpath, and the AAHA infection-control, prevention, and biosecurity guidelines.

Questions candidates ask

How long should I study for the VTNE? AAVSB doesn't set a study time. Our plan assumes about 42 hours over six weeks. Give yourself longer if you've been out of school a while or work full-time.

Is the VTNE hard? What's the pass rate? Pass rates vary widely by program. Our VTNE pass rates by school audit lays out the reported numbers and their limits.

Does the VTNE cover large animals and exotics? Yes. The species covered follow the AVMA essential and recommended skills list, not just dogs and cats.

Can I take the VTNE before I graduate? Some accredited programs allow last-semester testing; your program must upload you on its roster before you test. AAVSB must also confirm eligibility for your selected jurisdiction.

Sources and how we checked

By Castleport Test Prep Editorial Team. Last verified: October 17, 2026.

We checked the exam format, domain counts, scoring, fees, testing windows, retake rules, and eligibility pathways against the current AAVSB candidate handbook and AAVSB's VTNE pages. Every fact behind a practice question or review point was checked against the guideline, regulation, or other authoritative source linked beside it, and every calculation was recalculated. The study plan is our own editorial schedule. AI tools assisted with drafting, source checking, and editing. Source-checking is not professional veterinary review, and nothing here replaces your program's training or a veterinarian's instructions for a real patient.
