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?

A. Insert an indwelling urinary catheter: Monitoring urine output is essential for assessing renal perfusion and fluid status. However, it should be done only after hemodynamic stability is established and internal bleeding is ruled out, as catheterization can pose risks if pelvic fractures are present. B. Administer packed RBCs: Blood transfusion is necessary if the client is actively bleeding or hemodynamically unstable. However, access must first be secured to safely administer the transfusion, making IV insertion a priority. C. Place a large-bore IV catheter in an upper extremity: Establishing IV access is the first step in stabilizing a trauma patient. It allows for rapid fluid resuscitation, administration of medications, and drawing of lab specimens necessary for further assessment. D. Obtain a specimen for ABG analysis: Evaluating gas exchange and acid-base balance is important in trauma care, but it is not immediately life-saving. It should follow stabilization efforts like fluid resuscitation and hemorrhage control.
