A nurse is reinforcing teaching with a client who takes furosemide and has a serum potassium level of 3.1 mEq/L. Which of the following foods should the nurse instruct the client to include in his daily diet?

Choice A rationale: Tuberculosis treatment with rifampin typically lasts 6 to 9 months. Lifelong therapy is not required for TB, and unnecessary prolonged use increases the risk of drug resistance and hepatotoxicity.

Choice B rationale: Rifampin induces liver enzymes that accelerate the metabolism of oral contraceptives, making them less effective. It does not cause amenorrhea, but it necessitates the use of non-hormonal backup contraception.

Choice C rationale: Rifampin causes a harmless reddish-orange discoloration of urine, sweat, tears, and saliva. This can permanently stain soft contact lenses, so clients are advised to wear eyeglasses during the treatment course.

Choice D rationale: A yellow tint to the skin or sclera indicates jaundice, which is a sign of hepatotoxicity. This is a serious adverse effect rather than an expected reaction and must be reported immediately.

Choice A rationale:

The nurse should instruct the client to consume foods rich in potassium because furosemide, a loop diuretic, can lead to potassium depletion. By consuming potassium-rich foods, the client can help maintain proper electrolyte balance. Common potassium-rich foods include bananas, oranges, potatoes, and leafy greens. It is crucial to prevent hypokalemia, as it can result in adverse effects such as cardiac dysrhythmias and muscle weakness.

Choice B rationale:

Taking furosemide at bedtime is not necessary, and it is not a standard instruction. Furosemide is usually taken in the morning to avoid nocturia, as it increases urine output. This option does not address the primary concern of managing pulmonary edema and the potential electrolyte imbalances associated with furosemide use.

Choice C rationale:

Taking aspirin for headaches is not relevant to the client's condition of pulmonary edema or the use of furosemide. This choice does not provide valuable guidance to the client and may lead to unnecessary medication use.

Choice D rationale:

Expecting swelling in the hands and feet is not an appropriate instruction for a client with pulmonary edema. The goal of furosemide therapy is to reduce edema and fluid retention, not to expect or tolerate swelling. This option does not contribute to the client's well-being and recovery.
