Final answer:
The statement indicating a need for further instruction is: d) "I should take the medication with grapefruit juice."
Step-by-step explanation:
Immunosuppressive drugs are used to suppress the immune system in organ transplant recipients. It is important to take these medications as prescribed to prevent rejection of the transplanted organ. However, taking the medication with grapefruit juice can interfere with the metabolism of the drug, leading to higher levels of the drug in the body.
This can increase the risk of side effects and toxicity. Therefore, it is important to avoid taking immunosuppressive drugs with grapefruit juice.
