A nurse is caring for a group of clients. Which of the following clients should the nurse attend to 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.

- A. Assessing fluid intake every 24 hr is important for a postoperative client, but it is not the priority action. The nurse should monitor fluid intake and output more frequently, such as every 8 hr or every shift, to detect any imbalances or complications.

- B. Ambulating three times a day is beneficial for a postoperative client, but it is not the priority action. The nurse should encourage early and frequent ambulation to promote circulation, prevent thromboembolism, and enhance bowel function, but only after ensuring that the client is stable and has adequate pain control.

- C. Assisting with deep breathing and coughing is the priority action for a postoperative client who had abdominal surgery. The nurse should help the client perform these exercises every 1 to 2 hr to prevent atelectasis, pneumonia, and respiratory failure, which are common and serious complications after abdominal surgery.

- D. Monitoring the incision site for findings of infection is important for a postoperative client, but it is not the priority action. The nurse should inspect the wound for signs of infection, such as redness, swelling, warmth, drainage, or odor, but this can be done during routine dressing changes or as needed.
