The nurse is assessing a client who takes a loop diuretic. For what adverse effect should the nurse assess?

A. Hyperkalemia: Loop diuretics, such as furosemide, can cause hypokalemia (low potassium levels), not hyperkalemia. These diuretics increase potassium excretion, so it is important to monitor for low potassium rather than high potassium. B. Alkalosis: Loop diuretics can lead to metabolic alkalosis due to the loss of hydrogen ions and potassium in the urine. This can cause an imbalance in the body’s acid-base levels, so monitoring for signs of alkalosis is necessary. C. Hypertension: Loop diuretics are typically prescribed to treat hypertension and fluid overload, so they are not expected to cause hypertension. In fact, they help reduce blood pressure by reducing fluid volume. D. Hypercalcemia: Loop diuretics are more commonly associated with hypocalcemia (low calcium levels) because they increase calcium excretion. Hypercalcemia is not a typical adverse effect of these medications.
