B. 101.0–102.5°F
C. 97.0–98.0°F
D. 103.0–104.0°F
Answer: B
Rationale: Dogs normally maintain a temperature between 101–
102.5°F due to their metabolic rate and thermoregulation.
2. Which parasite is identified by the presence of ova with bipolar
plugs?
A. Toxocara canis
B. Ancylostoma caninum
C. Trichuris vulpis
D. Dipylidium caninum
Answer: C
Rationale: Trichuris vulpis (whipworm) eggs have characteristic
bipolar plugs.
3. A vaccine that contains live, weakened organisms is classified as:
A. Killed vaccine
B. Modified-live vaccine
C. Recombinant vaccine
D. Toxoid
Rationale: Modified-live vaccines contain attenuated organisms that
replicate to induce strong immunity.
,4. Which needle size is most appropriate for a feline SQ injection?
A. 16 gauge
B. 18 gauge
C. 22–25 gauge
D. 12 gauge
Rationale: Small-gauge needles minimize discomfort and are suitable

Rationale: RBCs transport oxygen via hemoglobin.
7. Which instrument is used to measure intraocular pressure?
A. Otoscope
B. Endoscope
C. Tonometer
D. Cautery unit
Rationale: A tonometer measures eye pressure for diagnosing
glaucoma.
, 8. A cat exhibiting icterus likely has elevated:

Rationale: Lead PPE reduces radiation exposure to the operator.
11. Which species is especially prone to hyperthermia during
anesthesia?
A. Goat
