A nurse is caring for a client who is prescribed cyclosporine. Which of the following findings should the nurse report to the provider immediately?

Choice A rationale Grapefruit juice contains compounds that inhibit cytochrome P450 3A4 (CYP3A4) enzymes in the small intestine. Cyclosporine is metabolized by CYP3A4. Concomitant ingestion of grapefruit juice can lead to increased serum cyclosporine levels, raising the risk of toxicity, including nephrotoxicity and neurotoxicity. Choice B rationale An increased serum bilirubin level can indicate liver dysfunction, which is a potential adverse effect of cyclosporine. However, without specific values or other symptoms, this finding alone might not be an immediate emergency, though it warrants further investigation to assess liver health. Normal total bilirubin is 0.3 to 1.2 mg/dL. Choice C rationale Hair growth (hirsutism) is a common and recognized side effect of cyclosporine therapy, particularly in women. While it can be bothersome cosmetically, it is generally not indicative of an immediate or life-threatening adverse event and does not require urgent reporting. Choice D rationale A blood pressure of 128/82 mm Hg is slightly elevated but generally considered within an acceptable range, although on the higher side of normal. Cyclosporine can cause hypertension, but this specific reading does not represent a hypertensive crisis or an immediate emergency requiring urgent intervention.
