1. Which of the following drugs is classified as a full mu-opioid agonist?
A. Butorphanol
B. Hydromorphone
C. Buprenorphine
D. Naloxone
Correct Answer: B
Rationale: Hydromorphone is a full mu-opioid agonist that provides potent analgesia for
moderate to severe pain. Butorphanol is a mixed agonist-antagonist, while buprenorphine
is a partial mu agonist. Naloxone is an opioid antagonist used to reverse the effects of
opioids.
2. When performing a Schirmer Tear Test, what is the minimum normal value for a healthy
canine patient?
A. 15 mm/min
B. 10 mm/min
,C. 5 mm/min
D. 25 mm/min
Correct Answer: A
Rationale: A normal Schirmer Tear Test result for a dog is typically 15 mm of moisture or
greater within one minute. Values between 11 and 14 mm are considered borderline, while
values below 10 mm indicate Keratoconjunctivitis Sicca. This test must be performed
before any drops or ointments are placed in the eye.
3. What is the dental formula for an adult feline?
A. 2(I 3/3, C 1/1, P 3/3, M 1/1) = 32
B. 2(I 3/3, C 1/1, P 4/4, M 2/3) = 42
C. 2(I 2/2, C 1/1, P 3/3) = 24
D. 2(I 3/3, C 1/1, P 3/2, M 1/1) = 30
Correct Answer: D
Rationale: The adult feline dental formula consists of 30 teeth in total, including incisors,
canines, premolars, and molars. Specifically, cats are missing the first upper premolar and
the first and second lower premolars. Understanding dental formulas is essential for
accurate charting and radiographic interpretation in veterinary dentistry.
, 4. In radiography, which setting primarily controls the quality or penetrating power of the X-
ray beam?
A. mA (milliamperage)
B. kVp (kilovoltage peak)
C. Exposure time (seconds)
D. Focal-film distance
Correct Answer: B
Rationale: Kilovoltage peak (kVp) determines the speed and energy of electrons hitting the
target, which controls the penetrating power of the X-ray beam. Increasing the kVp allows
the beam to pass through thicker or denser tissues. Milliamperage (mA) primarily controls
the quantity or total number of X-rays produced.
5. Which of the following suture materials is categorized as non-absorbable?
A. Silk
B. Polyglactin 910 (Vicryl)
C. Polydioxanone (PDS)
D. Chromic Gut
Correct Answer: A
Rationale: Silk is a natural, non-absorbable suture material often used for cardiovascular
or ophthalmic procedures. Polydioxanone and Polyglactin 910 are synthetic absorbable
