A nurse in the emergency department is receiving report on a group of clients. Which of the following clients should the nurse assess first?

Rationale: A. A client who has a complete femur fracture and reports a pain level of 7 on a scale from 0 to 10: Severe pain is significant and requires timely management, but it is not immediately life-threatening compared to acute cardiac events. Pain control should follow stabilization of critical conditions. B. A client who has left shoulder pain and S-T elevation on a 12-lead ECG: ST-segment elevation indicates a possible acute myocardial infarction, which is a life-threatening emergency. Prompt assessment and intervention are crucial to prevent cardiac damage or death, making this the highest priority. C. A client who has Clostridium difficile and a temperature of 38.5°C (101.5°F): Fever and infection require attention, but this client is currently stable compared with someone experiencing an acute myocardial infarction. Infection control and monitoring can follow stabilization of higher-priority emergencies. D. A client who has orthostatic hypotension and 4+ pitting edema in the lower extremities: These findings indicate fluid imbalance and cardiovascular compromise, but they are not as immediately life-threatening as an acute STEMI. Monitoring and management should follow urgent cardiac care.
