Final answer:
The client's statement that alerts the nurse to the need for clarification of the post-transplant drug regimen is that they should stop taking corticosteroids if they develop an infection.
Step-by-step explanation:
The correct statement from the client that alerts the nurse to the need for clarification of the post-transplant drug regimen is A.) "If I develop an infection, I should stop taking my corticosteroid."
This is incorrect because corticosteroids, like cyclosporine, are immunosuppressive drugs that are given to transplant recipients to prevent rejection. If the client develops an infection, stopping the corticosteroid can lead to an increased risk of rejection, as the immune system might become more active. Therefore, the client should continue taking the corticosteroids as prescribed and inform the healthcare team about any signs of infection.
