What is the most appropriate intervention for a patient with a suspected stroke?

Correct Answer: B

Rationale: The most appropriate intervention for a patient with a suspected stroke is to perform a CT scan. A CT scan is crucial for diagnosing a stroke by visualizing any bleeding or blockages in the brain. Administering IV fluids (Choice A) may be necessary based on the patient's condition, but it is not the primary intervention for a suspected stroke. Performing a lumbar puncture (Choice C) is not indicated for stroke evaluation and may not provide relevant information. Administering anticoagulants (Choice D) is a treatment option for certain types of strokes but should be based on the CT scan results and specific guidelines.

Correct Answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.

Correct Answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

Correct Answer: D

Rationale: Instructing the patient to use the spirometer every hour is crucial for optimal lung expansion and to prevent postoperative pulmonary complications. This regular use helps to keep the lungs clear and maintain their capacity. Choices A, B, and C are incorrect because deep breathing, forceful coughing, and blowing into the spirometer do not specifically address the proper use of the incentive spirometer, which is essential for postoperative respiratory recovery.

Correct Answer: A

Rationale: The correct answer is to monitor the patient's respiratory rate. This assessment is essential as it ensures that the patient is breathing adequately post-surgery. Maintaining a patent airway and adequate oxygenation are the top priorities in the immediate postoperative period. Monitoring blood pressure, checking the surgical site, or monitoring heart rate are important assessments but are not the priority immediately upon the patient's return from surgery.
