In an emergency scenario, which of the following would be a priority action concerning a patient with a cool and pulseless limb?

In an emergency scenario involving a patient with a cool and pulseless limb, splinting in the position found is a priority action because it minimizes further injury and preserves the limb's current state. If the limb is cool and lacks a pulse, it may indicate a severe condition, such as a vascular compromise or potential limb-threatening injury. By splinting the limb, you stabilize any fractures or soft tissue injuries, preventing movement that could exacerbate the situation.

Additionally, splinting helps to protect the limb while preparing for transport; it reduces the risk of further complications during movement. Other actions, such as evaluating temperature changes or attempting to obtain a pulse, may not provide immediate benefit in stabilizing the patient or preventing further harm, and transporting slowly to the hospital may delay care for an urgently injured limb. Thus, prioritizing splinting allows for a more effective response in a critical situation while ensuring the patient is as stable as possible for transport.
