Problem: The health care provider (HCP) has prescribed hydrocodone/APAP 1 tablet by mouth every 4 to 6 hours as needed for pain for a client who underwent right total knee replacement. When the nurse reassesses pain following administration, the client reports pain is still a 9 on a 10-point scale. When the nurse informs the HCP, the HCP states that one hydrocodone/APAP tablet should be sufficient and refuses to issue a new prescription. Which measure should the nurse select to act as an advocate for the client? Give the client 2 hydrocodone/APAP tablets every 4 hours. Document that the HCP was notified of the client's pain and continue to administer hydrocodone/APAP as prescribed. Give the client 1 hydrocodone/APAP tablet every 3 hours. Follow the chain of command to obtain adequate pain relief for the client.
