A patient receiving loop diuretics is at risk for which electrolyte imbalance?

Correct Answer: B

Rationale: The correct answer is B: Hypokalemia. Loop diuretics inhibit the reabsorption of sodium and water in the loop of Henle, leading to increased excretion of potassium, which can result in hypokalemia. Hypernatremia (A) is not a common electrolyte imbalance associated with loop diuretics. Hypercalcemia (C) is not typically caused by loop diuretics and is more commonly associated with other conditions. Hypophosphatemia (D) is not a primary concern with loop diuretics compared to the risk of hypokalemia.
