A patient with ventricular tachycardia and a pulse needs electrical intervention. What is the appropriate action?
- A. Defibrillation
- B. Synchronized cardioversion
- C. Pacing
- D. Medication administration
Correct Answer: B
Rationale: For a patient with ventricular tachycardia and a pulse, the appropriate action is synchronized cardioversion. Defibrillation is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing is typically used for bradycardias. Medication administration may be considered in stable ventricular tachycardia cases but electrical intervention is preferred for immediate correction in this scenario.

What is the first-line treatment for a patient experiencing wheezing and coughing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Methylprednisolone 100 mg IV
- C. Cromolyn 20 mg via nebulizer
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction as it quickly opens the airways, providing rapid relief. Choice B, Methylprednisolone 100 mg IV, is a systemic corticosteroid that may be used in severe cases to reduce inflammation but is not the initial treatment for acute wheezing. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that is more commonly used for prophylaxis rather than acute relief in allergic conditions. Choice D, Aminophylline 500 mg IV, is a bronchodilator that is less commonly used now due to its narrow therapeutic window and potential for toxicity, making it less preferred than Albuterol for initial treatment of wheezing.
What dietary recommendations should be provided for a patient with pre-dialysis end-stage kidney disease?
- A. Reduce phosphorus intake to 700 mg/day
- B. Increase sodium intake
- C. Restrict protein intake to 0.55-0.60 g/kg/day
- D. Limit potassium-rich foods
Correct Answer: A
Rationale: The correct recommendation for a patient with pre-dialysis end-stage kidney disease is to reduce phosphorus intake to 700 mg/day. Excessive phosphorus can be harmful to individuals with kidney disease as the kidneys may not be able to effectively remove it from the body. Choices B, C, and D are incorrect. Increasing sodium intake is generally not recommended for patients with kidney disease as it can lead to fluid retention and high blood pressure. Restricting protein intake is important in later stages of kidney disease, but for pre-dialysis end-stage kidney disease, protein intake should be individualized based on the patient's condition. Limiting potassium-rich foods is more relevant for patients with advanced kidney disease or those on dialysis, as impaired kidney function can lead to high potassium levels in the blood.
What precaution should be advised to a patient following a cataract surgery?
- A. Wear dark glasses while outdoors
- B. Avoid NSAIDs
- C. Use warm compresses
- D. Apply cold packs
Correct Answer: A
Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.
What should be done if a patient experiences abdominal cramping during enema administration?
- A. Lower the height of the enema solution container
- B. Stop the procedure and remove the tubing
- C. Continue the enema at a slower rate
- D. Increase the flow of the enema solution
Correct Answer: A
Rationale: When a patient experiences abdominal cramping during enema administration, the appropriate action is to lower the height of the enema solution container. This adjustment helps alleviate the cramping by reducing the pressure of the solution entering the colon. Stopping the procedure and removing the tubing (Choice B) is not necessary unless there are other complications. Continuing the enema at a slower rate (Choice C) may not address the immediate discomfort caused by cramping. Increasing the flow of the enema solution (Choice D) can exacerbate the cramping and should be avoided.
What are the signs of compartment syndrome?
- A. Unrelieved pain, pallor, pulselessness
- B. Muscle weakness, hyporeflexia
- C. Pins-and-needles sensation, swelling
- D. Severe swelling and tightness in the affected extremity
Correct Answer: A
Rationale: The correct signs of compartment syndrome include unrelieved pain, pallor, and pulselessness due to increased pressure within a muscle compartment. Choice B, muscle weakness, and hyporeflexia are not typical signs of compartment syndrome. Choice C, pins-and-needles sensation and swelling, are not specific signs of compartment syndrome. Choice D, severe swelling and tightness in the affected extremity, could be seen in compartment syndrome but are not the primary signs.
