Question : 1 / 258

You are consulted for management of delirium in a 53- year-old woman with metastatic renal cell carcinoma, severe pain, and metabolic disarray. Her pain is being managed unsuccessfully with a morphine-based regimen. Part of the problem is that she seems to become increasingly confused with the morphine even though it is underdosed. The team is distressed; they recognize that the morphine may be contributing to her delirium but feel stymied about how to manage her significant, multi-site cancer pain. What might be an appropriate initial strategy to improve analgesia without worsening delirium?
