1. What is the primary function of erythrocytes in animals?
A. Transport oxygen to tissues
B. Produce antibodies
C. Regulate blood clotting
D. Destroy pathogens
A. Transport oxygen to tissues
Rationale: Erythrocytes (red blood cells) contain hemoglobin, which binds
oxygen in the lungs and delivers it to body tissues while also carrying a portion
of carbon dioxide back for exhalation. This oxygen transport is essential for
cellular metabolism and survival.
2. Which instrument is commonly used to administer injectable vaccines in
small animals?
A. Scalpel
B. Syringe
C. Otoscope
D. Hemostat
B. Syringe
Rationale: A syringe is the standard device used to deliver injectable medications
,and vaccines. It allows precise dosing and is commonly paired with needles of
appropriate gauge for intramuscular, subcutaneous, or intravenous
administration.
3. What is the normal body temperature range for a healthy adult dog?
A. 32.5–34.0°C
B. 35.0–36.5°C
C. 38.0–39.2°C
D. 40.0–41.5°C
C. 38.0–39.2°C
Rationale: Dogs typically maintain a body temperature between 38.0°C and
39.2°C. Temperatures outside this range may indicate hypothermia or fever,
requiring further clinical evaluation.
4. Which parasite is commonly transmitted by fleas in cats?
A. Toxocara canis
B. Dipylidium caninum
C. Ancylostoma braziliense
D. Giardia lamblia
D. Giardia lamblia
Rationale: Giardia is a protozoan parasite causing intestinal infection, often
transmitted via contaminated water rather than fleas. Although not flea-borne,
it is a common feline intestinal parasite.
5. What is the correct position for restraining a dog for venipuncture?
A. Lateral recumbency
B. Standing or sitting
C. Supine only
D. Hanging restraint
,A. Lateral recumbency
Rationale: Lateral recumbency allows controlled access to veins such as the
cephalic or saphenous veins while minimizing stress and movement, making it
ideal for venipuncture procedures.
6. Which organ is primarily responsible for detoxification of drugs in animals?
A. Kidney
B. Liver
C. Pancreas
D. Spleen
B. Liver
Rationale: The liver metabolizes drugs and toxins through enzymatic processes,
converting them into more water-soluble compounds for elimination via bile or
urine.
7. What is the purpose of an autoclave in veterinary clinics?
A. Measuring temperature
B. Sterilizing instruments
C. Diagnosing infections
D. Mixing medications
C. Diagnosing infections
Rationale: This option is incorrect because autoclaves are not diagnostic tools.
They are used for sterilization using high-pressure steam.
8. Which of the following is a zoonotic disease?
A. Canine distemper
B. Feline leukemia virus
C. Rabies
D. Canine parvovirus
, C. Rabies
Rationale: Rabies is a viral zoonotic disease transmitted through saliva, typically
via bites, and can infect all mammals including humans, making it highly
significant in veterinary medicine.
9. What is the main function of leukocytes?
A. Oxygen transport
B. Blood clot formation
C. Immune defense
D. Hormone secretion
D. Hormone secretion
Rationale: This is incorrect because hormone secretion is performed by
endocrine glands. Leukocytes function in immune defense against pathogens.
10.Which route is most appropriate for rapid drug absorption in emergencies?
A. Oral
B. Topical
C. Intravenous
D. Rectal
C. Intravenous
Rationale: Intravenous administration delivers medication directly into the
bloodstream, providing immediate therapeutic effect, which is critical in
emergency situations.
11.What is the primary purpose of aseptic technique?
A. Increase drug potency
B. Prevent infection
C. Reduce animal stress
D. Improve nutrition
