A nurse is caring for a client who has an acute exacerbation of chronic pain. Which of the following medications should the nurse anticipate administering for the client?

Rationale: A. Naloxone: Naloxone is an opioid antagonist used to reverse opioid overdose. It does not provide pain relief and is not appropriate for managing acute exacerbations of chronic pain. B. Acetaminophen: Acetaminophen is useful for mild to moderate pain but may be insufficient for an acute exacerbation of chronic pain, especially if the client has severe or breakthrough pain. C. Fentanyl: Fentanyl is a potent opioid analgesic appropriate for managing severe acute pain or acute exacerbations of chronic pain. It acts rapidly to relieve pain and is often used in clients already tolerant to opioids. D. Zolpidem: Zolpidem is a sedative-hypnotic used to treat insomnia. It does not have analgesic properties and is not indicated for pain management.
