A nurse is caring for a client who has pulmonary edema and a new prescription for furosemide 40 mg IV twice daily. Which of the following client findings indicates the prescription is appropriate?

A. Bilateral coarse, crackle breath sounds: These are common findings in pulmonary edema due to fluid accumulation in the lungs. Furosemide, a diuretic, helps reduce fluid overload, making it an appropriate medication to help improve these symptoms by promoting diuresis. B. Vesicular breath sounds over the peripheral lung fields: Vesicular breath sounds are normal, and do not indicate the need for diuretics. The prescription for furosemide would be more appropriate if the client had signs of fluid overload, such as crackles. C. Potassium 3.2 mEq/L (3.5 mEq/L to 5.0 mEq/L): This indicates hypokalemia. Since furosemide can cause potassium depletion, the nurse should verify the prescription and monitor the client’s potassium levels closely, as additional supplementation may be needed. D. Blood pressure 100/70 mm Hg: This blood pressure is on the lower side of normal. While furosemide can lower blood pressure, this finding alone doesn't specifically indicate that the pulmonary edema is being effectively treated.
