Final answer:
Before administering hydromorphone, the nurse should notify the provider of an allergy to aspirin.
Step-by-step explanation:
Before administering hydromorphone for postoperative pain, the nurse should notify the provider of allergy to aspirin. Hydromorphone belongs to the opiate analgesics class, which includes substances such as morphine, oxycodone, and codeine. It is important to be cautious when administering opioids to individuals with a known allergy to aspirin because they may also have cross-sensitivity to opioids, which can lead to an allergic reaction.
