Which statement indicates that a client with cancer understands the proper disposal of fentanyl transdermal patches?

The statement indicating proper disposal of fentanyl transdermal patches is that the client will fold the patch with the adhesive sides inward before discarding it. This method is critical because it minimizes the risk of accidental exposure to the medication for anyone who may come into contact with the discarded patch. Fentanyl is a potent opioid, and inappropriate exposure can pose significant health risks.

The safe disposal practices for transdermal patches are designed to ensure that the potent medication does not accidentally affect others, including children, pets, and healthcare workers. By folding the patch with the sticky sides together, the client effectively prevents any remaining medication from leaking out during disposal, thereby enhancing safety.

The other disposal methods mentioned in the other choices either pose risks or are not recommended guidelines for handling controlled substances such as fentanyl. Throwing the patch in the regular trash or flushing it down the toilet could lead to unintended exposure or environmental contamination. Reusing the patch is also unsafe, as it can lead to inadequate pain management and potential for adverse effects.
