Final answer:
The nurse should dispose of the hydromorphone with a second nurse as a witness after the client declines to take the medication and document the disposal according to facility policy. This ensures medication safety and adherence to healthcare regulations.
Step-by-step explanation:
If a client declines to take medication after the nurse has already prepared the dose, the nurse should immediately adhere to the proper protocol for the disposal of medications. According to most healthcare facility policies, the correct action is for the nurse to dispose of the medication with a second nurse as a witness. This ensures that the medication is not misused or taken by someone for whom it was not prescribed, which could lead to medication errors or potential harm. Completing an occurrence report or encouraging the client to take the medication against their will would not be appropriate responses. Leaving the medication at the client's bedside also poses a significant safety risk and is against policy due to the possibility of the medication being taken incorrectly or by another person.
Furthermore, considering the seriousness of medication management and safety, particularly with controlled substances such as hydromorphone, the nurse should document the refusal and the disposal of the medication per the facility's policy. A witness is required for the disposal of controlled substances to prevent potential abuse or diversion, which could lead to incidents like the one mentioned where a healthcare worker tampered with syringes, leading to severe consequences for patients.
