In an emergency department, a healthcare provider is preparing to care for a client with multiple system trauma following a motor vehicle crash. What should be the priority focus of care?
Correct Answer: A
Rationale: The correct answer is A: Airway protection. The priority focus of care in a client with multiple system trauma is to ensure a patent airway to maintain oxygenation and ventilation. Without a clear airway, the client can rapidly deteriorate. Airway management takes precedence over other interventions to prevent hypoxia and respiratory failure. Decreasing intracranial pressure (B) and stabilizing cardiac arrhythmias (C) are important but secondary to ensuring adequate oxygenation. Preventing musculoskeletal disability (D) is not the immediate concern in this critical situation.
