1. A canine patient presents with severe vomiting and diarrhea. The
veterinarian suspects acute pancreatitis. Which of the following
laboratory findings is most consistent with this diagnosis?
A. Increased serum amylase and lipase
B. Decreased serum ALT
C. Increased serum BUN and creatinine
D. Decreased serum glucose
Answer: A
Explanation: In acute pancreatitis, pancreatic enzymes such as amylase
and lipase leak into the bloodstream, resulting in elevated serum levels.
While ALT may be elevated due to hepatobiliary involvement, it is not
decreased. BUN and creatinine elevations suggest renal impairment,
and glucose may be increased due to stress or decreased insulin
production, not decreased.

2. A feline patient is receiving intravenous fluid therapy. Which of the
following indicates that the patient is developing fluid overload?
A. Decreased respiratory rate
B. Decreased heart rate
C. Increased body weight and chemosis
D. Decreased packed cell volume (PCV)
Answer: C
Explanation: Chemosis (conjunctival edema) and acute weight gain are
early clinical signs of fluid overload. Respiratory rate typically increases,
not decreases, and heart rate may increase. PCV may decrease due to
hemodilution but is not a primary indicator of overload.
3. Which of the following anesthetic drugs is classified as a dissociative
anesthetic and is commonly used for restraint in feline patients?
A. Propofol
B. Ketamine
C. Isoflurane
D. Acepromazine
Answer: B
Explanation: Ketamine is a dissociative anesthetic that produces
catalepsy and analgesia while maintaining pharyngeal and laryngeal

reflexes. Propofol is a general intravenous anesthetic, isoflurane is an
inhalant, and acepromazine is a tranquilizer.
4. In a lateral thoracic radiograph of a dog, the cardiac silhouette
appears elevated and separated from the sternum. This finding is most
suggestive of:
A. Cardiomegaly
B. Pericardial effusion
C. Megaesophagus
D. Diaphragmatic hernia
Answer: C
Explanation: Megaesophagus causes the air-filled esophagus to displace
the heart dorsally, creating a separation between the cardiac silhouette
and the sternum. Cardiomegaly and pericardial effusion typically
enlarge the cardiac silhouette but do not elevate it.
5. A technician is performing a dental prophylaxis on a dog. Which of
the following teeth are most likely to be affected by the presence of a
carnassial tooth abscess?
A. Premolar 4 and molar 1
B. Incisor 1 and incisor 2
C. Canine and premolar 2
D. Molar 2 and premolar 3
, 4|Page
Answer: A
Explanation: In the dog, the maxillary fourth premolar and the
mandibular first molar are the carnassial teeth. Abscesses most
commonly involve the maxillary fourth premolar (carnassial tooth) due
to its large root structure and deep periodontal pockets.
6. A feline patient presents with a history of chronic weight loss,
polyuria, polydipsia, and a plantigrade stance. Which of the following is
the most likely diagnosis?
A. Hyperthyroidism
B. Diabetes mellitus
C. Chronic kidney disease
D. Hypothyroidism
Answer: B
Explanation: The classic clinical signs of diabetes mellitus in cats include
polyuria, polydipsia, weight loss, and distal neuropathy leading to a
plantigrade stance. Hyperthyroidism also causes weight loss but
typically with polyphagia, not polyuria/polydipsia. Chronic kidney
disease causes PU/PD but not plantigrade stance.
7. During a surgical procedure, the patient's heart rate drops from 120
bpm to 60 bpm, and the mucous membranes become pale. The most
appropriate immediate action is to:
