A nurse is caring for a client who has a prescription for a fentanyl transdermal patch and had one patch applied 4 hr ago. The client reports breakthrough pain. Which of the following actions should the nurse take?

A. A long-acting NSAID is not appropriate for breakthrough pain when a fentanyl patch is already in use, as it is not fast-acting enough. B. Applying heat to the patch can increase the absorption of fentanyl, which could cause an overdose. C. The fentanyl patch is a long-acting opioid, and a new patch should not be applied for breakthrough pain so soon. D. A short-acting opioid is appropriate for treating breakthrough pain, as it provides rapid relief.
