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. Morphine typically causes miosis (constricted pupils), not dilation. A pupil diameter of 6 mm (dilated pupils) is not an expected therapeutic effect, but it is not the most immediately life-threatening finding in this scenario compared with severe hypotension. B. This equates to about 30 mL/hr, which is borderline low but still may be acceptable depending on the client’s weight, hydration status, and clinical context. Morphine can also cause urinary retention, so this finding should be monitored but is not the priority. C. Constipation is a very common adverse effect of morphine due to decreased gastrointestinal motility. While important to address with stool softeners or laxatives, it is not an acute emergency. D. This is the priority finding because it indicates severe hypotension, which can lead to decreased tissue perfusion, shock, and organ failure. Morphine can cause vasodilation and histamine release, contributing to hypotension, especially when given IV. This requires immediate intervention and provider notification first, as it is life-threatening.
