A nurse is assessing a client who is receiving morphine IV for pain. Which of the following findings should the nurse report to the provider first?

Rationale: A. Pupil diameter 6 mm: Dilated pupils may indicate CNS stimulation or sensitivity, but this finding is less immediately life-threatening than significant hypotension. Pupil size should still be monitored, especially for signs of overdose or neurologic changes. B. Blood pressure 80/40 mm Hg: Severe hypotension is a critical adverse effect of IV morphine that can compromise perfusion to vital organs. It requires immediate attention to prevent shock, making this the highest priority finding to report. C. Urinary output 120 mL/4 hr: While this output is slightly below normal, it does not yet indicate acute kidney injury. Continued monitoring is warranted, but it is not the most urgent issue compared to hypotension. D. Bowel movement 5 days ago: Constipation is a common side effect of opioids, but it typically develops gradually and can be managed with bowel protocols. It is not as urgent as hypotension and can be addressed after stabilizing the client.
