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. Urinary output 120 mL/4 hr. This is on the lower end of normal but not critical. It should be monitored, especially in clients on opioids, but does not require immediate reporting ahead of more life-threatening findings. B. Pupil diameter 6 mm. Dilated pupils may suggest other issues such as anxiety, medication effects, or pain, but are not a common concern with morphine, which usually causes miosis (pupil constriction). Still, this is not the most urgent concern. C. Bowel movement 5 days ago. Constipation is a common side effect of opioids, including morphine, and should be addressed with stool softeners or laxatives. However, it is not an emergency. D. Blood pressure 80/40 mm Hg. This indicates hypotension, a potentially life-threatening side effect of IV morphine, especially if it results in decreased perfusion or shock. It requires immediate intervention and provider notification.
