Final answer:
The client should be advised to take the cyclosporine solution on an empty stomach. Taking it with grapefruit juice should be avoided. Regular blood pressure monitoring is important.
Step-by-step explanation:
The client should be advised to take the oral cyclosporine solution on an empty stomach.
Taking the medication with grapefruit juice should be avoided, as it can increase the concentration of cyclosporine in the blood and potentially lead to toxicity.
Regular blood pressure monitoring is important for a client who has received a heart transplant, so option a) should be avoided. Additionally, discontinuing the medication if side effects occur (option d) should only be done under the guidance of a healthcare provider.
