VTNE Emergency and Critical Care Questions and Answers

Question 1

A 10-year-old male cat is presented to the emergency clinic for straining to urinate with no urine production for the past 12 hours. Upon examination, he is bradycardic (110 bpm), and his bladder is large and firm. Which of the following is the most immediate life-threatening concern for this patient?

Accepted Answer

Life-threatening hyperkalemia

Answer

While azotemia, pain, and bladder rupture are all serious concerns, severe hyperkalemia (high potassium) is the most immediate threat to life. Urethral obstruction prevents the excretion of potassium, which leads to toxic levels in the blood, causing severe bradycardia and potentially fatal cardiac arrhythmias.

Question 2

According to the most recent RECOVER guidelines for veterinary CPR, what is the recommended rate and depth for chest compressions in most dogs and cats?

Accepted Answer

100-120 compressions per minute, compressing the chest by 1/3 to 1/2 its width.

Answer

The RECOVER (Reassessment Campaign on Veterinary Resuscitation) initiative has established evidence-based guidelines for CPR. The recommended rate for chest compressions is 100-120 per minute, and the depth should be 1/3 to 1/2 the width of the chest, allowing for full chest recoil between compressions.

Question 3

A dog is presented after being hit by a car. The technician notes a heart rate of 160 bpm, pale mucous membranes, and a capillary refill time of 3 seconds. Which stage of shock is this patient most likely exhibiting?

Accepted Answer

Decompensated shock

Answer

These clinical signs—tachycardia, pale mucous membranes, and prolonged capillary refill time—are classic indicators of decompensated shock. The body's initial compensatory mechanisms (like increasing heart rate to maintain blood pressure) are starting to fail, leading to poor tissue perfusion.

Question 4

A 4-year-old dog presents with acute onset of weakness, ataxia, and vomiting after the owner says he ate a pack of sugar-free gum. The most immediate life-threatening metabolic disturbance to monitor for is:

Accepted Answer

Profound hypoglycemia

Answer

Sugar-free gum often contains xylitol, which is extremely toxic to dogs. Ingestion causes a massive, rapid release of insulin, leading to profound and life-threatening hypoglycemia (low blood sugar). While high doses can also cause liver failure, hypoglycemia is the most immediate and acute concern.

Question 5

A cat presents in severe respiratory distress. Radiographs confirm a large volume of pleural effusion. What is the primary therapeutic goal of performing an immediate thoracocentesis?

Accepted Answer

To allow for lung re-expansion and improve ventilation.

Answer

The primary goal of a therapeutic thoracocentesis is to remove the fluid from the pleural space that is physically compressing the lungs and preventing them from inflating. Removing the fluid relieves this pressure, allows the lungs to re-expand, and immediately improves the patient's ability to breathe.
