The nurse is preparing to teach a client about the prescribed furosemide (Lasix). The nurse should instruct the client about which adverse effect?

Number 4 is correct.

Furosemide (Lasix) is a diuretic that inhibits the absorption of sodium and chloride from the loop of Henle and distal renal tubule. This action increases renal excretion of water, sodium, chloride, magnesium, potassium, and calcium. This reduction of body fluid and electrolytes may produce a dry mouth. Appetite is not affected by furosemide. Leg cramps are an adverse effect of hypokalemia.
