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 medication to administer for a patient experiencing wheezing due to an allergic reaction?
- A. Albuterol 3 ml via nebulizer
- B. Cromolyn 20 mg via nebulizer
- C. Methylprednisolone 100 mg IV
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is the first-line medication for wheezing due to its rapid bronchodilatory effects. Choice B, Cromolyn, is used more for preventing allergic reactions rather than acute relief of wheezing. Choice C, Methylprednisolone, is a steroid used for its anti-inflammatory effects and is not the initial choice for acute relief of wheezing. Choice D, Aminophylline, is a bronchodilator but is not the first-line treatment for wheezing due to allergic reactions.
What are the expected manifestations in a patient experiencing a thrombotic stroke?
- A. Sudden numbness or loss of function on one side of the body
- B. Sudden loss of consciousness and seizure
- C. Gradual onset of difficulty speaking
- D. Loss of sensation in the affected limb
Correct Answer: A
Rationale: The correct manifestation in a patient experiencing a thrombotic stroke is sudden numbness or loss of function on one side of the body. This is due to the blockage of a blood vessel by a clot, leading to a lack of blood flow to a specific part of the brain. Choices B, C, and D are incorrect. Sudden loss of consciousness and seizure are more commonly associated with hemorrhagic strokes. Gradual onset of difficulty speaking is often seen in ischemic strokes affecting language areas, not specifically in thrombotic strokes. Loss of sensation in the affected limb is more indicative of sensory nerve damage rather than the motor deficits seen in thrombotic strokes.
What are the priority lab values to monitor in a patient with HIV?
- A. CD4 T-cell count below 180 cells/mm3
- B. White blood cell count
- C. Hemoglobin levels
- D. Serum albumin levels
Correct Answer: A
Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A CD4 count below 180 cells/mm3 is considered severe immunocompromise and requires close monitoring and intervention. Choices B, C, and D are not the priority lab values to monitor in HIV patients. While white blood cell count, hemoglobin levels, and serum albumin levels can provide valuable information about the patient's health status, they are not as specific or indicative of HIV disease progression and management as the CD4 T-cell count.
What is the priority dietary modification for a patient with pre-dialysis end-stage kidney disease?
- A. Limit phosphorus intake to 700 mg/day
- B. Increase potassium intake to 3 g/day
- C. Eat three large meals per day
- D. Restrict protein intake to 1 g/kg/day
Correct Answer: A
Rationale: The correct answer is A: Limit phosphorus intake to 700 mg/day. In patients with pre-dialysis end-stage kidney disease, restricting phosphorus intake is crucial to manage their condition. Excessive phosphorus can lead to mineral and bone disorders, which are common in kidney disease. Choice B, increasing potassium intake, is not the priority and can be harmful as kidney disease often leads to hyperkalemia. Choice C, eating three large meals per day, is not recommended as smaller, frequent meals are usually better tolerated. Choice D, restricting protein intake to 1 g/kg/day, is important in later stages of kidney disease but is not the priority at the pre-dialysis stage.
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.
