The questions

Domain: Pharmacy & Pharmacology

Question 1. A 48 lb dog needs medication at 20 mg/kg. How many mg are required?

  1. A220 mg
  2. B440 mg
  3. C960 mg
  4. D968 mg
Show answer and rationale

Answer: B. 440 mg

Convert pounds to kilograms first: 48 lb ÷ 2.2 = 21.8 kg, rounded to 22 kg. Then multiply by the dose: 22 kg × 20 mg/kg = 440 mg (436.4 mg without rounding, so 440 mg is still the closest option). Multiplying the dose by the weight in pounds instead of kilograms is the classic error.

Domain: Dentistry

Question 2. Using the modified Triadan system, what is the designation for the right maxillary central incisor in a cat?

  1. A1
  2. B101
  3. C111
  4. D201
Show answer and rationale

Answer: B. 101

In the modified Triadan system the first digit is the quadrant (1 right maxilla, 2 left maxilla, 3 left mandible, 4 right mandible) and the last two digits are the tooth position counted from the midline, with the canine always 04 and the first molar always 09. The right maxillary central incisor is therefore 101.

Domain: Laboratory Procedures

Question 3. A canine PCV is 12%. Which finding on the blood smear would indicate the anemia is regenerative?

  1. ANumerous target cells only
  2. BNumerous polychromatophils
  3. CMarked rouleaux formation
  4. DMany hypersegmented neutrophils
Show answer and rationale

Answer: B. Numerous polychromatophils

Polychromatophils are immature red cells released early from marrow and stain bluish with Romanowsky stains; they correspond to reticulocytes and are the smear hallmark of regeneration. Rouleaux reflects protein changes, not regeneration.

Domain: Diagnostic Imaging

Question 4. If a radiograph of the abdomen appears too dark and lacks contrast (overpenetrated), what adjustment should be made for the retake?

  1. AIncrease kVp by 10-15%
  2. BDecrease mAs by 30-50%
  3. CIncrease mAs by 30-50%
  4. DDecrease kVp by 10-15%
Show answer and rationale

Answer: D. Decrease kVp by 10-15%

Radiographic density is primarily controlled by mAs, while contrast (penetration) is controlled by kVp. If the image is too dark and lacks contrast (overpenetrated), the correct adjustment is to decrease kVp by 10-15%. A 10-15% change in kVp alters penetration and the scale of contrast; mAs stays the same when overall density is otherwise acceptable.

Domain: Anesthesia

Question 5. When should the endotracheal tube cuff be deflated during recovery?

  1. AOnly after removal, as it should never be deflated in the trachea
  2. BJust before extubation, once protective swallowing reflexes are returning
  3. CImmediately after the procedure ends, before the vaporizer is even turned off
  4. DAbout ten minutes before the patient is expected to wake up
Show answer and rationale

Answer: B. Just before extubation, once protective swallowing reflexes are returning

The cuff is the airway protection, so it stays inflated while the patient is still obtunded and at risk of regurgitation. It is deflated immediately before removal, and the tube is withdrawn as swallowing returns.

Domain: Animal Care & Nursing

Question 6. An 18 kg patient needs maintenance fluids at 40 mL/kg/day. What is the required hourly fluid rate?

  1. A30 mL/hr
  2. B14 mL/hr
  3. C66 mL/hr
  4. D720 mL/hr
Show answer and rationale

Answer: A. 30 mL/hr

Daily requirement: 18 kg × 40 mL/kg/day = 720 mL/day. Hourly rate: 720 mL ÷ 24 hours = 30 mL/hr, rounded to 30 mL/hr. Forgetting to divide by 24 gives the daily volume (720) as a rate, a common and dangerous error.

Domain: Surgical Nursing

Question 7. Which part of a draped surgical table is regarded as sterile?

  1. AOnly the top surface; anything below table level is non-sterile
  2. BThe entire draped table, including the sides down to the floor
  3. CThe top and the first few centimeters of the sides below the edge
  4. DAll of the drape, until it has been touched by a non-sterile item
Show answer and rationale

Answer: A. Only the top surface; anything below table level is non-sterile

Drape edges hanging below the table cannot be monitored and may contact non-sterile surfaces. An instrument that slips below table level is contaminated even if it never visibly touches anything.

Domain: Emergency & Critical Care

Question 8. What is the immediate first aid for a chemical splash to the eye?

  1. AApplying an antibiotic ointment and rechecking
  2. BCovering the eye and waiting for the veterinarian
  3. CNeutralizing the chemical with an opposite pH solution
  4. DImmediate prolonged lavage with saline or clean water
Show answer and rationale

Answer: D. Immediate prolonged lavage with saline or clean water

Dilution and removal limit the depth of injury, and every minute of delay increases damage. Attempting chemical neutralization generates heat and worsens the injury.

Domain: Pain Management & Analgesia

Question 9. What should be documented after giving a rescue analgesic dose?

  1. AThe drug name only, since dose and time are recorded in the drug log
  2. BNothing beyond the drug log, because it was a single additional dose
  3. COnly the time of administration, so the next scheduled dose can be adjusted
  4. DThe score prompting it, drug, time, and the reassessment score afterwards
Show answer and rationale

Answer: D. The score prompting it, drug, time, and the reassessment score afterwards

The reassessment closes the loop and demonstrates whether the intervention worked. Without it, a repeatedly ineffective drug can be given for days without anyone noticing the pattern.

Domain: Communication & Professional Support

Question 10. Why must the correct disinfectant contact time be observed?

  1. ALonger contact times damage treated surfaces, so the time is a maximum
  2. BContact time affects only how much product is used, not how well it works
  3. CA brief wipe is as effective as a longer one once the surface is visibly clean
  4. DDisinfectants need a set wet contact time to achieve their claimed kill
Show answer and rationale

Answer: D. Disinfectants need a set wet contact time to achieve their claimed kill

Wiping a surface and drying it immediately does not disinfect it regardless of the product used. Parvovirus in particular requires a specific agent and an adequate wet contact period.
