GRADED A+
1. A veterinary technician is preparing to induce anesthesia in a healthy canine patient. Which
injectable anesthetic is classified as a dissociative anesthetic and is commonly combined with
a benzodiazepine to improve muscle relaxation?
A. Propofol
B. Ketamine
C. Alfaxalone
D. Thiopental
Answer: B
Rationale: Ketamine is a dissociative anesthetic that produces analgesia and amnesia but poor
muscle relaxation when used alone. It is commonly combined with a benzodiazepine such as
diazepam or midazolam to improve muscle relaxation and provide smoother induction and
recovery.
2. A blood sample for a complete blood count (CBC) should be collected in which type of
tube?
A. Red-top tube
B. Green-top tube
C. Lavender-top EDTA tube
D. Gray-top tube
,Answer: C
Rationale: Lavender-top tubes contain EDTA, an anticoagulant that preserves blood cell
morphology and prevents clotting, making them the preferred tube for hematology testing.
3. A dog presents with pale mucous membranes and a capillary refill time of 3 seconds. Which
condition is most likely?
A. Adequate tissue perfusion
B. Hypertension
C. Hypovolemia or poor peripheral perfusion
D. Hyperthyroidism
Answer: C
Rationale: Pale mucous membranes together with a prolonged capillary refill time indicate
decreased peripheral circulation, commonly associated with hypovolemia, shock, severe
anemia, or cardiovascular compromise.
4. Which surgical instrument is specifically designed to grasp and hold a suture needle during
tissue closure?
A. Mosquito hemostat
B. Allis tissue forceps
C. Thumb forceps
D. Mayo-Hegar needle holder
Answer: D
Rationale: Mayo-Hegar needle holders are designed specifically to hold suture needles
securely while suturing. Mosquito hemostats are used to clamp small blood vessels, Allis
tissue forceps grasp tissue, and thumb forceps assist in tissue manipulation.
5. Which parasite is transmitted by mosquitoes and commonly infects the pulmonary arteries
of dogs?
A. Ancylostoma caninum
B. Dipylidium caninum
,C. Dirofilaria immitis
D. Toxocara canis
Answer: C
Rationale: Dirofilaria immitis, commonly known as heartworm, is transmitted by mosquitoes.
Adult worms reside primarily in the pulmonary arteries and may extend into the right side of
the heart in severe infections. Prevention through routine heartworm prophylaxis is
recommended.
6. Which monitoring device continuously measures end-tidal carbon dioxide (ETCO₂) during
anesthesia?
A. Pulse oximeter
B. Electrocardiograph (ECG)
C. Capnograph
D. Doppler blood pressure monitor
Answer: C
Rationale: A capnograph measures end-tidal carbon dioxide, providing continuous assessment
of ventilation, airway patency, and the effectiveness of cardiopulmonary function. It is one of
the most valuable anesthetic monitoring tools.
7. The normal resting heart rate of a healthy adult cat is approximately:
A. 60–100 beats per minute
B. 80–120 beats per minute
C. 100–140 beats per minute
D. 140–220 beats per minute
Answer: D
Rationale: The normal resting heart rate for an adult cat ranges from approximately 140 to
220 beats per minute. Stress and excitement during examination can temporarily increase the
heart rate.
8. Which instrument is routinely used to determine urine specific gravity?
A. Hemocytometer
, B. Spectrophotometer
C. Refractometer
D. Centrifuge
Answer: C
Rationale: A refractometer measures the refractive index of urine to determine urine specific
gravity. This test provides valuable information regarding kidney concentrating ability and the
patient's hydration status.
9. Persistent vomiting most commonly results in which acid-base imbalance?
A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Respiratory alkalosis
Answer: B
Rationale: Vomiting results in the loss of gastric hydrochloric acid, leading to metabolic
alkalosis. Associated electrolyte abnormalities often include hypochloremia and hypokalemia.
10. Which vaccine is classified as a core vaccine for dogs?
A. Bordetella bronchiseptica
B. Lyme disease vaccine
C. Rabies vaccine
D. Canine influenza vaccine
Answer: C
Rationale: Rabies vaccination is considered a core vaccine because rabies is a fatal zoonotic
disease and vaccination is legally required in many jurisdictions.
11. During cardiopulmonary resuscitation (CPR), chest compressions should generally be
delivered at which rate?
A. 60–80 compressions per minute
B. 80–100 compressions per minute
