A nurse in a provider's office is reviewing the laboratory results of a client who takes furosemide for hypertension. The nurse notes that the client's potassium level is 3.3 mEq/L. The nurse should monitor the client for which of the following complications?

Rationale: A. Seizures are more commonly associated with severe electrolyte imbalances like hyponatremia, not mild hypokalemia. B. Neurogenic shock is related to spinal cord injury, not potassium imbalance. C. Hypokalemia (potassium 3.3 mEq/L; normal 3.5–5.0 mEq/L) increases the risk of ventricular arrhythmias, palpitations, and potentially life-threatening cardiac complications, especially in clients taking diuretics like furosemide. D. Low potassium does not directly cause hypoglycemia.
