The nurse is reinforcing discharge teaching with a client about a new prescription for furosemide. Which of the following client statements indicates an understanding of the teaching?

A. "I need to limit my sun exposure and wear sunscreen while on this medication.": Furosemide is known to cause photosensitivity reactions, making the skin more susceptible to severe sunburns and rashes. Clients should be educated to practice sun safety, including the use of protective clothing and high-SPF sunscreen. This statement demonstrates an understanding of the dermatological risks associated with loop diuretics. B. "I should limit my fluid intake while taking this medication.": Unless the client has a specific fluid restriction due to heart or kidney failure, they should maintain adequate hydration to prevent dehydration. Furosemide promotes significant diuresis, and excessive restriction can lead to severe volume depletion and hypotension. The medication is designed to remove excess fluid, not necessarily restrict intake. C. "My blood pressure will increase while I am taking this medication.": Furosemide typically causes a decrease in blood pressure by reducing the total circulating fluid volume. It is often used as an antihypertensive agent to manage fluid-related hypertension. A client expecting a blood pressure increase does not understand the primary hemodynamic effect of the drug. D. "I should eat a diet low in potassium while taking this medication.": Furosemide is a potassium-wasting diuretic that increases the excretion of potassium in the distal convoluted tubule. Clients usually require a high-potassium diet or supplements to prevent hypokalemia and associated cardiac arrhythmias. A low-potassium diet would exacerbate the risk of a dangerous electrolyte deficiency.
