A nurse in an emergency department is planning care for a client who has abdominal trauma from a motor-vehicle crash. Which of the following provider prescriptions should the nurse implement first?

Rationale: A. Insert an indwelling urinary catheter: While important for monitoring urine output and renal perfusion, catheter insertion is not the immediate priority in a trauma situation. It should be done after vascular access is secured and life-threatening conditions are addressed. B. Administer packed RBCs: Blood transfusion is critical for managing hemorrhagic shock, but it cannot be initiated until a large-bore IV is placed. Vascular access is necessary before any fluid or blood product administration. C. Obtain a specimen for ABG analysis: ABGs provide valuable data on oxygenation and acid-base balance but are diagnostic rather than life-sustaining. This step is less urgent than establishing IV access for fluid resuscitation or transfusion. D. Place a large-bore IV catheter in an upper extremity: In trauma care, rapid IV access is the top priority to allow fluid and blood product resuscitation. A large-bore catheter ensures high-volume administration, which is essential in potential hemorrhagic shock.
