Which intervention is important to include in the care plan while a patient receives multiple immunosuppressants?

• A. Instruct client to wear a mask when walking in the halls.
• B. Instruct visitors that fresh flowers should not be taken into the room.
• C. Monitor immunosuppression drug levels regularly.
• D. The client should be assisted with mobility and not restricted.

Answer: (C)

Regular monitoring of immunosuppressant drug levels is essential when a patient is on multiple immunosuppressants. These medicines have narrow therapeutic windows and their levels can be affected by interactions with other drugs, organ function (liver and kidneys), and adherence. By routinely measuring trough (and sometimes peak) levels, the care team can adjust dosing to keep exposure in the therapeutic range, reducing the risk of organ rejection from too little exposure and toxicity or infection from too much exposure. Infection precautions and mobility support are important for overall safety, but they don’t directly ensure proper drug exposure like ongoing drug level monitoring does.
