BCSE Veterinary Surgical Principles 5

Question 1

Which of the following suture materials has the LONGEST retention of tensile strength, making it suitable for closure of body wall in large-breed dogs?

Accepted Answer

Polydioxanone (PDS)

Answer

Polydioxanone (PDS) retains approximately 70% of its tensile strength at 2 weeks and 50% at 4 weeks, making it ideal for slowly healing tissues such as the linea alba.

Question 2

A dog undergoing orthopedic surgery develops shivering and a rectal temperature of 35.5°C (95.9°F). Which intraoperative measure is MOST effective in preventing further heat loss?

Accepted Answer

Use forced-air warming blankets and warm IV fluids

Answer

Forced-air warming blankets are the most effective active rewarming modality during surgery, and warming IV fluids prevents further core temperature loss.

Question 3

During a cystotomy closure, which suture pattern is recommended for the bladder wall to provide a watertight seal?

Accepted Answer

Two-layer closure with an inverting pattern such as Cushing or Lembert over a simple continuous

Answer

A two-layer closure using a simple continuous first layer followed by an inverting Cushing or Lembert pattern provides a secure, watertight, leak-resistant bladder closure.

Question 4

Which of the following is the most important principle when selecting a surgical approach (incision location) for an abdominal procedure?

Accepted Answer

The incision should provide adequate exposure of the target structure while minimizing trauma to surrounding tissues

Answer

The surgical approach should balance adequate exposure of the target organ with minimal disruption to surrounding structures, nerves, and vasculature.

Question 5

A ferret presents for adrenalectomy. Which vessel must be carefully preserved or managed to avoid serious intraoperative hemorrhage, particularly during right adrenalectomy?

Accepted Answer

Caudal vena cava

Answer

The right adrenal gland is intimately associated with the caudal vena cava, and inadvertent laceration during right adrenalectomy can cause life-threatening hemorrhage.
