Q1.
A research facility introduces a new transgenic mouse line with a mutation in the leptin
receptor. Compared to wild-type controls, these mice exhibit hyperphagia, obesity, and
glucose intolerance. Which behavioral change is most likely to be observed during the
light phase of a 12:12 light-dark cycle?
A. Increased stereotypic grooming B. Decreased nesting behavior
C. Increased feeding bouts during the light D. Reduced locomotor activity in the dark
phase phase
Correct: C - Increased feeding bouts during the light phase
Rationale:Leptin receptor-deficient mice lack satiety signaling, leading to hyperphagia.
Normally nocturnal, they show increased feeding during the light phase due to constant
hunger. Stereotypic grooming is not directly linked; nesting may be reduced due to obesity but
not specific. Locomotor activity in dark phase may be normal or reduced, but light phase
feeding is the key behavioral shift.
Q2.
A technician notices that a group of Sprague-Dawley rats housed in solid-bottom cages
with corncob bedding have developed alopecia and erythema on their ventral surfaces.
The facility uses automated watering and the cages are changed weekly. Which
environmental factor is most likely contributing to this condition?
A. Ammonia concentration due to infrequent B. Contact dermatitis from corncob bedding
cage changes
C. High humidity from poor ventilation D. Urine scald from wet bedding
Correct: D - Urine scald from wet bedding
Rationale:Ventral alopecia and erythema in rats housed on solid-bottom cages with corncob
bedding often result from urine scald when bedding becomes saturated. Automated watering
can leak, and weekly changes may be insufficient. Ammonia causes respiratory issues, not
localized dermatitis. Corncob is generally non-irritating. Humidity is systemic, not localized to
ventral skin.
Q3.
In a study using C57BL/6 mice, researchers need to collect blood samples for
pharmacokinetic analysis. They require serial sampling from the same animal over 24
hours with minimal stress and maximum sample volume per time point. Which blood
collection method is most appropriate?
Page 3
, Section A - Animal CARE AND Husbandry
A. Retro-orbital sinus puncture under B. Saphenous vein puncture without
isoflurane anesthesia anesthesia
C. Tail vein nick with manual restraint D. Submandibular vein puncture with
isoflurane anesthesia
Correct: A - Retro-orbital sinus puncture under isoflurane anesthesia
Rationale:Retro-orbital sinus puncture allows rapid collection of large volumes (up to 200 µL)
and can be repeated after a recovery period, ideal for serial PK studies. Saphenous and tail
vein yield smaller volumes and are more stressful. Submandibular is good for single samples
but less suitable for serial large volumes. Anesthesia reduces stress.
Q4.
A veterinarian prescribes buprenorphine (0.1 mg/kg SC) for postoperative analgesia in a
25 g mouse. The available solution is 0.3 mg/mL. What volume (in mL) should be
administered?
A. 0.0083 B. 0.083
C. 0.83 D. 8.3
Correct: A - 0.0083
Rationale:Dose = 0.1 mg/kg × 0.025 kg = 0.0025 mg. Volume = dose / concentration =
0.0025 mg / 0.3 mg/mL = 0.00833 mL. Option B is 0.083 mL (10× too large), C is 0.83 mL
(100×), D is 8.3 mL (1000×). Accurate calculation is critical for safe dosing.
Q5.
During a routine health monitoring, a technician observes that a group of New Zealand
White rabbits have soft feces, reduced appetite, and are grinding their teeth. No other
clinical signs are present. Which condition is most likely?
A. Mucoid enteropathy B. Dental malocclusion
C. Cecal dysbiosis D. Pasteurellosis
Correct: C - Cecal dysbiosis
Rationale:Soft feces, anorexia, and bruxism (teeth grinding) in rabbits are classic signs of
cecal dysbiosis, often due to stress or diet change. Mucoid enteropathy presents with mucoid
feces and more severe GI stasis. Dental malocclusion causes weight loss and drooling but
not soft feces. Pasteurellosis typically involves respiratory signs.
