CVA Surgical and Exam Procedures 4 — Questions and Answers
Question 1: During a physical exam, a veterinary assistant notices a patient's mucous membranes are pale and tacky. What does this most likely indicate?
- Hypertension
- Dehydration or poor perfusion (Correct answer)
- Fever
- Hypoglycemia
Correct answer: Dehydration or poor perfusion
Pale, tacky mucous membranes are classic signs of dehydration or inadequate tissue perfusion.
Question 2: Which knot is most commonly used to tie off suture in veterinary surgery due to its security?
- Slip knot
- Square knot (Correct answer)
- Granny knot
- Half-hitch knot
Correct answer: Square knot
The square knot is the standard surgical knot because it lies flat and is less likely to loosen than a granny knot.
Question 3: A dog is recovering from anesthesia and begins paddling its legs and vocalizing. What is the most appropriate initial response?
- Administer additional anesthetic
- Restrain firmly with a muzzle
- Keep the patient calm, padded, and notify the veterinarian (Correct answer)
- Leave the patient to recover undisturbed
Correct answer: Keep the patient calm, padded, and notify the veterinarian
Dysphoric or excitatory recovery requires gentle restraint, padding to prevent injury, and immediate veterinarian notification.
Question 4: When preparing a surgical site, in what direction should you clip and scrub the skin?
- From the periphery toward the incision site
- From the incision site outward in a circular motion (Correct answer)
- In random directions to cover the entire area
- Parallel to the spine only
Correct answer: From the incision site outward in a circular motion
Surgical scrubbing moves from the clean center outward to avoid introducing contaminants to the incision site.
Question 5: Which of the following is the correct capillary refill time (CRT) in a healthy dog or cat?
- Less than 1 second
- 1–2 seconds (Correct answer)
- 3–4 seconds
- More than 5 seconds
Correct answer: 1–2 seconds
A normal CRT is 1–2 seconds; prolonged CRT suggests poor perfusion or cardiovascular compromise.
Question 6: What is the purpose of a Balfour retractor during abdominal surgery?
- To clamp bleeding vessels
- To hold abdominal walls open for better visualization (Correct answer)
- To aspirate fluid from the abdominal cavity
- To anchor sutures to the abdominal wall
Correct answer: To hold abdominal walls open for better visualization
The Balfour retractor is a self-retaining instrument used to hold the abdominal incision open during surgery.
Question 7: During a routine physical exam, you auscultate lung sounds and hear a crackling noise on inspiration. What might this indicate?
- Normal breath sounds
- Upper airway obstruction
- Fluid in the lower airways (pulmonary edema or pneumonia) (Correct answer)
- Cardiac arrhythmia
Correct answer: Fluid in the lower airways (pulmonary edema or pneumonia)
Crackles (rales) on auscultation are associated with fluid or exudate in the alveoli, suggesting pulmonary edema or pneumonia.
