Subject Code: FVR-C-P
Duration: 3 hours
Total Marks: 100
Instructions: Answer all questions. Select the single best answer for each multiple-choice
question. Each question is worth 2 marks unless otherwise stated.
Section A: Feline Vaccination Protocols
Question 1
A kitten presents for its initial vaccination series. According to current feline vaccination
guidelines, what is the recommended age to administer the first FVRCP (modified live) vaccine?
A. 4-5 weeks
B. 6-9 weeks
C. 10-12 weeks
D. 16 weeks
Answer: B
Explanation: The FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia) vaccine series
typically begins at 6-9 weeks of age. A total of 3 doses are recommended in the initial series,
usually given every 3-4 weeks.
Question 2
A kitten receives its first FeLV (subunit) vaccine at 8 weeks of age. How many total FeLV
vaccines are required for the initial immunization series?
A. 1
B. 2
C. 3
D. 4
,Answer: B
Explanation: The feline leukemia virus (FeLV) subunit vaccine requires a total of 2 doses in the
initial series, starting at 6-9 weeks of age. This ensures adequate protective immunity.
Question 3
At what minimum age should the rabies (killed) vaccine be administered to a kitten according to
standard veterinary guidelines?
A. 8 weeks
B. 10 weeks
C. 12 weeks
D. 16 weeks
Answer: C
Explanation: The killed rabies vaccine is recommended starting at 12 weeks of age. Local legal
requirements may vary, but this is the standard medical recommendation.
Question 4
Which of the following correctly categorizes feline core vaccines by their vaccine type?
A. FVRCP (killed), FeLV (modified live), rabies (subunit)
B. FVRCP (modified live), FeLV (subunit), rabies (killed)
C. FVRCP (subunit), FeLV (killed), rabies (modified live)
D. FVRCP (modified live), FeLV (modified live), rabies (killed)
Answer: B
Explanation: Feline core vaccines include FVRCP as a modified live vaccine, FeLV as a
subunit vaccine, and rabies as a killed (inactivated) vaccine. This combination provides optimal
safety and efficacy.
, Section B: Parasitology & Immunology Fundamentals
Question 5
Why are cats considered less susceptible to heartworm disease (Dirofilaria immitis) compared to
dogs?
A. Cats produce microfilariae that are rapidly cleared
B. Cats are natural hosts with high worm burdens
C. Cats typically harbor only 1-3 adult worms and do not produce microfilariae
D. Cats have innate immunity that completely prevents infection
Answer: C
Explanation: Cats are less susceptible because they are not a natural host for heartworms. When
infection occurs, cats typically harbor only 1-3 adult worms and rarely produce microfilariae,
leading to lower diagnostic rates and milder clinical signs.
Question 6
A dog presents with pruritus, erythema, and urticaria within 30 minutes of exposure to an
allergen. This reaction is mediated by which immune mechanism?
A. Type IV hypersensitivity, T-cell mediated
B. Type I hypersensitivity, mast cell degranulation
C. Type II hypersensitivity, antibody-dependent cytotoxicity
D. Type III hypersensitivity, immune complex deposition
Answer: B
Explanation: Atopic dermatitis involves Type I hypersensitivity, where IgE antibodies bind to
mast cells. Upon allergen re-exposure, mast cells degranulate and release histamine and other
mediators, causing rapid-onset pruritus and inflammation.
