A 72-year-old patient with advanced pancreatic cancer is receiving palliative care. She experiences persistent, severe nausea and vomiting despite receiving standard antiemetics (ondansetron, prochlorperazine). Her pain is well-controlled with opioids. What is the most appropriate next step in managing her nausea and vomiting?
✓ Correct Answer: Option D
In patients with advanced cancer and refractory nausea on opioids, it's crucial to evaluate for underlying treatable causes like opioid-induced gastroparesis or bowel obstruction. Managing these specific issues is often more effective than adding more symptomatic antiemetics.
