A nurse is providing teaching about the use of transdermal fentanyl patches to a client. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Folding the patch in half with the medication side touching before disposal is correct because it prevents accidental exposure to residual medication. Fentanyl patches contain potent opioids, and improper disposal can lead to accidental ingestion or misuse. This practice ensures safety for both the client and others in the household. Choice B reason: Cutting the patch in half is unsafe. Transdermal patches are designed to deliver medication at a controlled rate. Cutting them compromises the integrity of the delivery system, leading to unpredictable dosing and risk of overdose. Choice C reason: Applying a heating pad to the patch is contraindicated. Heat increases absorption of fentanyl through the skin, which can result in toxic levels and respiratory depression. Clients should avoid external heat sources on or near the patch. Choice D reason: Rotating the patch to a different extremity each day is incorrect. Patches should be applied to intact, non-irritated skin on the upper torso or upper arm, not rotated daily to extremities. Rotation is important, but it should be between recommended sites every 72 hours, not daily.
