Final answer:
The nurse should notify the prescribing provider about the client's refusal to accept the new pouch containing the fentanyl patch.
Step-by-step explanation:
The correct action for the nurse to take when the client declines to accept the new pouch is option D: Notify the prescribing provider about the situation.
This is important because fentanyl is a strong opioid medication that requires strict handling and monitoring. The nurse should inform the prescribing provider about the client's refusal to accept the new pouch to ensure appropriate patient care and to follow the necessary protocols.
By notifying the prescribing provider, the nurse can seek further guidance and discuss alternatives or adjustments to the medication plan to address the client's concerns.
