Match each clinical scenario in advanced illness with the most appropriate next step in targeted symptom management.
- A patient with NYHA class IV heart failure who struggles with intractable shortness of breath at rest despite maximal medical optimization, and has never received opioid therapy.Initiate low-dose oral morphine
- An individual with terminal pancreatic malignancy complicated by an inoperable malignant bowel obstruction, experiencing recurrent crampy abdominal pain and profuse emesis.Administer subcutaneous octreotide
- A patient with diffuse spinal metastases from breast carcinoma who reports severe, sharply localized back pain that worsens with movement despite around-the-clock opioid administration.Prescribe dexamethasone and refer for palliative radiation
- A patient with advanced renal cell carcinoma and declining kidney function who develops progressive confusion, diffuse tactile sensitivity, and spontaneous muscle jerks while receiving high-dose oral morphine.Rotate to an alternative opioid such as fentanyl or methadone
Answer
Intractable dyspnea is managed with low-dose morphine; malignant bowel obstruction with octreotide; focal metastatic bone pain with dexamethasone and palliative radiation; and opioid-induced neurotoxicity requires rotation to fentanyl or methadone.
Each scenario requires a precise palliative approach: modifying central respiratory drive for dyspnea, decreasing GI secretions for bowel obstruction, reducing peritumoral inflammation for bone metastases, and clearing toxic metabolites by rotating therapies for neurotoxicity.
