Question 1

A dog undergoing surgery develops bradycardia. Which drug is most commonly used to treat this condition intraoperatively?

Accepted Answer

Atropine

Answer

Atropine is an anticholinergic drug that blocks vagal tone and increases heart rate, making it the first-line treatment for intraoperative bradycardia.

Question 2

What type of needle is preferred for suturing skin in veterinary patients?

Accepted Answer

Reverse cutting needle

Answer

Reverse cutting needles have the cutting edge on the outer curve, making them ideal for tough tissues like skin because they resist cutting through the suture line.

Question 3

Which laboratory value is most useful for evaluating hepatic (liver) function in dogs and cats?

Accepted Answer

Alanine aminotransferase (ALT)

Answer

ALT is a liver-specific enzyme in dogs and cats; elevations indicate hepatocellular damage, making it the primary marker for hepatic disease.

Question 4

During patient preparation for surgery, what is the minimum distance the clipped area should extend beyond the incision site?

Accepted Answer

2 inches (5 cm) on each side

Answer

The standard is to clip at least 2 inches (5 cm) beyond the planned incision on all sides to provide an adequate sterile surgical field.

Question 5

Which type of suture material is absorbable and commonly used for internal tissues in veterinary surgery?

Accepted Answer

Polyglycolic acid (PGA)

Answer

Polyglycolic acid (PGA) is a synthetic absorbable suture material commonly used for internal tissues because it degrades by hydrolysis over time.
