A nurse is admitting a client who has pneumonia. The nurse should initiate which of the following isolation precautions for the client?

Choice A rationale:

Hanging the transfusion with dextrose 5% in 0.9% sodium chloride is incorrect. Packed red blood cells (PRBCs) are transfused with normal saline (0.9% sodium chloride) and not with dextrose-containing solutions. Using dextrose can cause the red blood cells to hemolyze.

Choice B rationale:

Infusing the transfusion over 5 hours is incorrect. PRBC transfusions are typically administered over 2-4 hours, not 5 hours. Infusing the blood too slowly may cause the patient discomfort and may also increase the risk of bacterial growth in the blood product.

Choice C rationale:

Using a 20-gauge IV catheter to transfuse the blood is incorrect. While a 20-gauge IV catheter is suitable for most blood transfusions, it may not be appropriate for older adults or patients with fragile veins. A smaller gauge, such as 22 or 24, might be more suitable to prevent phlebitis and ensure a steady flow without damaging the blood cells.

Choice D rationale:

Monitoring vital signs every hour throughout the transfusion is the correct action. During a blood transfusion, it's crucial to monitor the patient's vital signs frequently to detect any adverse reactions promptly. Vital signs, including blood pressure, heart rate, respiratory rate, and temperature, should be assessed before the transfusion, 15 minutes after starting the transfusion, and then hourly thereafter. This vigilant monitoring helps in identifying potential transfusion reactions, such as fever, chills, or hypotension, allowing for immediate intervention if needed.

- 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.
