A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?

A) Check for correct placement of the patch behind the client's ear: While it's important to ensure the patch is properly placed, the timing of the client’s symptoms suggests that the patch might not be the appropriate treatment for pain, rather than a placement issue. B) Offer to apply a new transdermal patch to relieve the pain: This action is not appropriate. Scopolamine is primarily used to prevent nausea and motion sickness, not to treat pain. Applying a new patch without understanding the client’s needs could lead to unnecessary medication administration. C) Explain that the medication is not given to prevent pain: This is the correct response. The nurse should clarify that scopolamine is intended for managing nausea and not for pain relief. This understanding is crucial for the client’s expectations regarding treatment. D) Advise the client that the effects of the medication have worn off: This statement is misleading because scopolamine is not meant to provide pain relief. The effects of the patch would not wear off in a way that would result in pain unless the client was experiencing nausea or another issue that the patch is designed to prevent.
