In the case of a client with a history of drug addiction, which medication should the nurse avoid using immediately after administering nalbuphine?

In a client with a history of drug addiction, it is crucial to be cautious about the administration of medications that could precipitate withdrawal symptoms or adverse effects. Nalbuphine is an opioid analgesic that can act as both an agonist and antagonist at opioid receptors, which means it can block the effects of other opioids.

Using naloxone hydrochloride immediately after administering nalbuphine is not advisable because naloxone is an opioid antagonist. If naloxone is administered after nalbuphine, it could negate the analgesic effects of nalbuphine and potentially precipitate withdrawal symptoms, especially in someone with a history of opioid dependency. This is significant because clients with a background of drug addiction may be more sensitive to changes in opioid modulation and could experience discomfort or a resurgence of craving if withdrawal is triggered.

Other choices such as local anesthetics or a pudendal block do not interact with nalbuphine in the same way and can be used safely to manage pain without risking withdrawal or antagonist effects. Therefore, naloxone should be avoided immediately after nalbuphine administration in this context to ensure the safety and comfort of the client.
