In the ED, a patient with suspected left lower extremity fractures and a pain score of 10: what is the most important initial action?

• A. Administer high-dose analgesia.
• B. Assess for life-threatening injuries.
• C. Obtain X-ray of the leg.
• D. Immobilize the leg.

Answer: (B)

In trauma care, the first priority is to identify and manage life-threatening conditions through the primary survey. For a patient with suspected leg fracture and severe pain, you must immediately assess for threats to life—airway, breathing, circulation, and neurologic status. If there are any airway issues, signs of breathing trouble, heavy bleeding, or signs of shock, those problems must be stabilized right away. Focusing on the limb or giving analgesia before ruling out or treating these threats can delay care for conditions that could otherwise become fatal. Once the patient’s airway, breathing, and circulation are secure and stabilized, you can immobilize the leg, manage pain appropriately, and obtain imaging to evaluate the fracture.
