A nurse is caring for a client whose partner died in a fire that destroyed their home. Which of the following actions should the nurse take first?

A. This choice is incorrect because verapamil and TPN do not have a significant food and medication interaction. Verapamil is a calcium channel blocker that can lower blood pressure and heart rate, while TPN is a form of intravenous nutrition that provides calories, electrolytes, vitamins, and minerals. The nurse should monitor the client's vital signs and blood glucose levels, but there is no need to intervene to prevent an interaction.

B. This choice is incorrect because phenytoin and milkshakes do not have a significant food and medication interaction. Phenytoin is an anticonvulsant that can decrease the absorption of some vitamins, such as folic acid and vitamin D, but milkshakes are not a major source of these nutrients. The nurse should encourage the client to eat a balanced diet and take supplements as prescribed, but there is no need to intervene to prevent an interaction.

C. This choice is incorrect because potassium-rich foods and furosemide do not have a significant food and medication interaction. Furosemide is a loop diuretic that can cause hypokalemia, or low potassium levels, but potassium-rich foods can help prevent this complication. The nurse should monitor the client's electrolyte levels and fluid balance, but there is no need to intervene to prevent an interaction.

D. This choice is correct because MAOIs and cheeseburgers have a significant food and medication interaction. MAOIs are antidepressants that can cause hypertensive crisis, or dangerously high blood pressure, if the client consumes foods that contain tyramine, such as aged cheeses, cured meats, fermented foods, and beer. The nurse should intervene to prevent the client from eating a cheeseburger and educate the client about avoiding tyramine-containing foods while taking MAOIs.

Choice A reason

Ensuring that the client's family supports the provider's decision for surgery is not an appropriate action. While family support is essential in the decision-making process, the primary responsibility lies with the client's health care surrogate or designated decision-maker. The family's support is not a substitute for obtaining informed consent from the designated decision-maker.

Choice B reason

Sending the unsigned informed consent form to the facility's risk manager is not appropriate action. The nurse should not send an unsigned informed consent form to the facility's risk manager. Unsigned consent forms do not have any legal significance or validity. The nurse should work with the health care surrogate to ensure that the consent form is appropriately completed and signed.

Choice C reason

Determining if the procedure is medically necessary for the client is not appropriate action. While the medical necessity of the procedure is important, the decision about the procedure's necessity should be made by the medical team and discussed with the health care surrogate. The nurse's role is to facilitate communication and ensure that the surrogate is informed and involved in the decision-making process.

Choice D reason

When a client is in a coma and unable to provide informed consent, the health care surrogate or designated decision-maker becomes responsible for making medical decisions on behalf of the client. It is essential for the nurse to ensure that the health care surrogate is aware of the situation, understands the risks and benefits of the surgical procedure, and has provided informed consent on behalf of the client.
