A nurse is providing discharge teaching for parents of a child who has congestive heart failure and is about to start taking furosemide. Which of the following instructions should the nurse include?

A. Furosemide is a loop diuretic that can cause potassium loss; therefore, it is essential for the child to eat potassium-rich foods to prevent hypokalemia. B. Taking furosemide at bedtime is not advisable due to the increased risk of nocturia and sleep disturbances from frequent urination. C. Aspirin is not recommended without medical guidance, especially for children, as it can increase the risk of Reye's syndrome. D. Expecting swelling in the hands and feet contradicts the purpose of furosemide, which is to reduce fluid overload; parents should report any unexpected swelling to the healthcare provider.
