A nurse is reinforcing discharge teaching with a client who has pulmonary edema and is about to start taking furosemide.
Which of the following instructions should the nurse include?

Choice A rationale:

The nurse should identify that the client needs liver function tests while taking pyrazinamide. Pyrazinamide is one of the drugs used to treat tuberculosis, and it is known to potentially cause hepatotoxicity (liver damage). Regular monitoring of liver function tests, including liver enzymes like ALT and AST, is essential to detect any liver-related issues early and ensure the client's safety during the medication therapy.

Choice B rationale:

Thyroid function studies are not typically necessary while a client is taking pyrazinamide. Pyrazinamide is not known to have a direct effect on thyroid function.

Choice C rationale:

Blood glucose levels do not need to be monitored specifically due to pyrazinamide therapy. Although some antituberculosis drugs may affect blood sugar levels, pyrazinamide is not a common culprit for such side effects.

Choice D rationale:

Gallbladder studies are not typically indicated while taking pyrazinamide. Pyrazinamide is not known to cause specific issues related to the gallbladder. Monitoring liver function is more critical due to its potential hepatotoxicity.

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.
