Free VTNE Emergency and Critical Care Questions and Answers — Questions and Answers
Question 1: A client rushes into the clinic with a cat that was just hit by a car. The cat is laterally recumbent, has pale mucous membranes, a weak, thready femoral pulse at 220 bpm, and is vocalizing. According to the principles of triage, which immediate action is the highest priority?
- Obtaining a detailed history from the owner.
- Placing an intravenous catheter and starting shock-rate fluids. (Correct answer)
- Administering pain medication.
- Taking thoracic and abdominal radiographs.
Correct answer: Placing an intravenous catheter and starting shock-rate fluids.
The cat is presenting with classic signs of hypovolemic shock (pale mucous membranes, tachycardia, weak/thready pulses). The highest priority in emergency triage is to address life-threatening circulation problems. Placing an IV catheter and initiating fluid resuscitation is essential to restore intravascular volume and improve tissue perfusion.
Question 2: According to the RECOVER (Reassessment Campaign on Veterinary Resuscitation) guidelines, what is the recommended rate for chest compressions during cardiopulmonary resuscitation (CPR) in most dogs and cats?
- 60-80 compressions per minute
- 80-100 compressions per minute
- 100-120 compressions per minute (Correct answer)
- 120-150 compressions per minute
Correct answer: 100-120 compressions per minute
The RECOVER guidelines, which are the evidence-based standard for veterinary CPR, recommend a chest compression rate of 100-120 per minute for both dogs and cats. This rate is crucial for maintaining adequate blood flow to vital organs during cardiac arrest.
Question 3: A dog presents to the emergency service after ingesting a large amount of dark chocolate. Which of the following clinical signs is most commonly associated with methylxanthine toxicity?
- Bradycardia and lethargy
- Hypothermia and ataxia
- Tachycardia and hyperactivity (Correct answer)
- Anemia and jaundice
Correct answer: Tachycardia and hyperactivity
The toxic compounds in chocolate are methylxanthines (theobromine and caffeine), which act as stimulants. They primarily affect the central nervous and cardiovascular systems, leading to signs such as restlessness, hyperactivity, tremors, tachycardia, and arrhythmias.
Question 4: A 10 kg dog is diagnosed with severe dehydration and hypovolemic shock. The veterinarian orders an initial fluid bolus of isotonic crystalloids to be administered over 15 minutes. Based on standard resuscitation protocols, what is the most appropriate volume for this initial bolus?
- 900 mL
- 225 mL (Correct answer)
- 500 mL
- 100 mL
Correct answer: 225 mL
The standard shock dose of isotonic crystalloids for a dog is approximately 90 mL/kg. The total shock volume for a 10 kg dog would be 900 mL. An initial bolus is typically one-quarter (1/4) of the total shock dose. Therefore, 900 mL / 4 = 225 mL. This initial bolus is given rapidly, usually over 15-20 minutes, before the patient is reassessed.
Question 5: A cat presents with an open-mouth breathing pattern, cyanotic mucous membranes, and muffled heart and lung sounds on auscultation. A thoracic FAST scan reveals a large volume of pleural effusion. The veterinarian will likely perform which of the following emergency procedures to stabilize the patient?
- Pericardiocentesis
- Thoracocentesis (Correct answer)
- Abdominocentesis
- Tracheostomy
Correct answer: Thoracocentesis
Thoracocentesis is the procedure of draining fluid or air from the pleural space (the space surrounding the lungs). In a patient with significant pleural effusion causing respiratory distress, this procedure is both diagnostic and therapeutic, as it removes the fluid that is compressing the lungs and preventing them from expanding fully.
Question 6: A 7-year-old Doberman Pinscher presents for collapse. An ECG reveals a heart rate of 180 bpm with wide, bizarre QRS complexes that do not have associated P waves. This arrhythmia is best identified as:
- Sinus tachycardia
- Atrial fibrillation
- Third-degree AV block
- Ventricular tachycardia (Correct answer)
Correct answer: Ventricular tachycardia
Ventricular tachycardia (V-tach) is a life-threatening arrhythmia characterized by a rapid heart rate originating from an ectopic focus within the ventricles. The classic ECG findings are a rapid rate with wide and bizarrely shaped QRS complexes and a lack of association with P waves (AV dissociation).
