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?

A. Bowel movement 5 days ago: Constipation is a common side effect of morphine and should be addressed, but it is not immediately life-threatening and can be managed with laxatives or stool softeners. B. Pupil diameter 6 mm: Pupil dilation is not a typical concern with morphine; miosis (constriction) is more commonly expected. While abnormal pupil size can indicate neurologic or drug-related issues, hypotension takes priority here. C. Blood pressure 80/40 mm Hg: Hypotension is a serious adverse effect of morphine that may indicate circulatory depression. It requires immediate intervention to prevent inadequate organ perfusion and potential shock. D. Urinary output 120 mL/4 hr: This output equals 30 mL/hr, which is within the expected minimum range. No immediate intervention is required, though continued monitoring is appropriate.
