What is the preferred nursing intervention for a client taking hydromorphone and requesting pain medication again after receiving the medication four hours prior?

The preferred nursing intervention in this scenario, where a client is taking hydromorphone (Dilaudid) and requesting pain medication again after receiving it four hours prior, is to administer only the Dilaudid every four hours as needed for pain. This approach prioritizes the safe and effective management of the client's pain while adhering to the medication's prescribed dosing schedule.

Hydromorphone is a powerful opioid analgesic used for severe pain management. Its pharmacokinetics typically allow for administration every four to six hours, depending on the individual’s pain level and the prescribing guidelines. Administering hydromorphone within the recommended time frame is critical to prevent both inadequate pain control and the risk of overdose.

Using only Dilaudid ensures that the client receives consistent pain relief in a controlled manner, minimizing potential adverse effects associated with polypharmacy or medication interactions. The other options imply a combination of medications that might not be appropriate without specific orders and can introduce unnecessary risks of overdose or inadequate pain management.
