A nurse is caring for a group of adolescents. Which of the following findings should be reported to the provider immediately?

A. A client's blood pressure changes from 112/60 mm Hg to 90/54 mm Hg when standing: This significant drop in blood pressure upon standing indicates orthostatic hypotension, which can be an early sign of hypovolemia or autonomic instability. It requires immediate evaluation to prevent complications like syncope or shock. B. A client who has an ankle fracture reports a pain level increase from 3 to 5 after initial ambulation: A mild to moderate increase in pain after activity is expected in injuries. While it should be monitored, it does not require immediate provider notification unless unrelieved by interventions or accompanied by neurovascular changes. C. A client who has a burn injury to an estimated 5% of his leg and is crying: Crying in response to a burn injury reflects pain or emotional distress but is not an urgent clinical concern with only 5% total body surface area involvement. Pain should be managed, but the situation is not immediately life-threatening. D. A client who is 1 day postoperative and has a temperature of 37.5° C (99.5° F): This temperature is within the normal postoperative range and can reflect the body's inflammatory response to surgery. It does not indicate infection or a critical issue that needs immediate reporting.
