Q1. What is the normal resting heart rate range for a healthy adult medium to large breed dog?
Correct answer: A. 60-120 bpm
A resting heart rate of roughly 60-120 bpm is normal for a medium to large adult dog. Small dogs and cats normally run faster.
Q2. Which restraint method is most appropriate for safely performing jugular venipuncture on an uncooperative cat?
Correct answer: B. Full body wrap ("cat burrito") with the head extended
Wrapping the cat's body in a towel while extending the head and neck immobilizes the limbs and reduces the risk of scratches or bites during jugular draws.
Q3. A veterinary technician assigns a body condition score (BCS) of 8/9 to a canine patient. Which finding best supports this score?
Correct answer: C. Ribs difficult to palpate under a heavy fat layer, with no visible waist
A BCS of 8/9 indicates obesity, characterized by a thick fat layer over the ribs and loss of a visible waist or abdominal tuck.
Q4. When placing an indwelling urinary catheter in a male dog, which step helps reduce the risk of introducing contamination into the bladder?
Correct answer: D. Using strict aseptic technique and a new sterile catheter for each attempt
Aseptic technique with a sterile, single-use catheter and sterile lubricant minimizes the risk of ascending urinary tract infection.
Q5. Which behavioral sign is most consistent with acute pain in a hospitalized cat as assessed using the Feline Grimace Scale?
Correct answer: A. Squinted eyes, flattened ears, and a tense muzzle
The Feline Grimace Scale scores facial features including orbital tightening, ear position, and muzzle tension; squinted eyes, flattened ears, and a tense muzzle indicate pain.
Q6. A 20 kg dog is assessed as 8% dehydrated. Using the standard formula (body weight in kg x % dehydration x 1000 = mL fluid deficit), what is the calculated fluid deficit to replace, not including maintenance needs?
Correct answer: B. 1600 mL
20 kg x 0.08 x 1000 = 1600 mL. This is the estimated volume needed to correct the fluid deficit, separate from ongoing maintenance fluid requirements.
Q7. Current pre-anesthetic fasting guidelines recommend withholding food from a healthy adult dog for approximately how long before elective anesthesia?
Correct answer: C. 6-12 hours
Most healthy adult dogs are fasted approximately 6-12 hours before elective anesthesia to reduce the risk of regurgitation and aspiration, while avoiding prolonged fasting that can cause hypoglycemia.
Q8. During general anesthesia, a patient in a surgical plane of anesthesia (stage III, plane 2) typically shows which combination of signs?
Correct answer: D. Central, ventromedially rotated eye position with relaxed jaw tone and slow regular respiration
A light-to-moderate surgical plane is characterized by central eye position, relaxed jaw tone, and slow regular respiration, indicating adequate depth without excessive depression.
Q9. A dog becomes markedly bradycardic after receiving dexmedetomidine as part of a premedication protocol. Which drug can be administered to reverse this effect?
Correct answer: A. Atipamezole
Atipamezole is an alpha-2 adrenergic antagonist that specifically reverses the sedative and cardiovascular effects of dexmedetomidine.
Q10. A patient anesthetized with isoflurane develops progressive hypotension despite an adequate anesthetic depth. Which mechanism most likely explains isoflurane's contribution to this hypotension?
Correct answer: B. Isoflurane causes dose-dependent vasodilation and decreased systemic vascular resistance
Isoflurane primarily lowers blood pressure through dose-dependent peripheral vasodilation and reduced systemic vascular resistance rather than direct myocardial depression.
