A nurse is caring for four clients who are all requesting assistance. Which of the following clients should the nurse assist first?

A. A client who has fallen represents an acute change in status and a high risk for physical injury, such as fractures or intracranial hemorrhage. According to nursing prioritization frameworks, actual safety threats and acute incidents take precedence over routine care or discomfort. The nurse must immediately assess the client for stability, neurological deficits, and musculoskeletal integrity to prevent further harm or complications. B. Nausea in a postoperative client is a common clinical finding often related to anesthesia or opioid analgesics. While it causes significant distress and carries a risk of emesis and aspiration, it is generally considered a "stable" discomfort compared to an acute fall. The nurse should address this by administering prescribed antiemetics, but only after ensuring that no other clients are in immediate physical danger. C. A beeping IV pump typically indicates an occlusion, an empty infusion bag, or a low battery. While this requires intervention to maintain the scheduled delivery of fluids or medications, it is a technical issue that does not pose an immediate threat to the client's life. Most IV pumps have a built-in "keep vein open" (KVO) rate or battery backup, allowing for a brief delay in troubleshooting. D. Requesting a bedpan is a basic physiological need related to elimination. While timely assistance is necessary to maintain skin integrity and prevent the patient from attempting to ambulate unassisted (which could lead to a fall), it is a routine care task. In a prioritization scenario, the nurse must first attend to the client who has already experienced an injury or acute event.
