A nurse is teaching a client who is awaiting a heart transplant. Which statement indicates the client understands what is required to help minimize rejection?

When a person receives a heart transplant, their immune system may recognize the new heart as foreign and try to attack it. To prevent this, the client will need to take medication to suppress their immune system and prevent rejection. Option A is incorrect because it states that the client will need to take three different types of medication for the rest of their life, which is not necessarily true. Option B is incorrect because there is always a risk of rejection, even if the donor heart is a close match. Option D is incorrect because medication before and during surgery is not enough to eliminate the risk of rejection. Option C is the correct answer because it acknowledges the need for medication to prevent rejection and the possibility of not needing medication if the body does not reject the new heart. Therefore, the correct answer is C.
