A client reports muscle cramps in the calves and feeling "tired a lot." The client is taking ethacrynic acid (Edecrin) for hypertension. Based on these symptoms, the client will be evaluated for which electrolyte imbalance?

furosemide

A client with severe hypervolemia is prescribed a loop diuretic and the nurse is concerned with the client experiencing significant sodium and potassium losses. What drug was most likely prescribed?
