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?
Administer packed RBCS.
Obtain a specimen for ABG analysis.
Place a large-bore IV catheter in an upper extremity.
Insert an indwelling urinary catheter.
The Correct Answer is C
A. Administer packed RBCs. While blood transfusion may be urgently needed for hemorrhagic shock, it cannot be initiated until vascular access is established. It is important, but not the first step.
B. Obtain a specimen for ABG analysis. Arterial blood gases can provide valuable information about respiratory and metabolic status, but they are not the top priority in an unstable trauma patient.
C. Place a large-bore IV catheter in an upper extremity. Establishing IV access is the priority in trauma care, as it allows for rapid fluid resuscitation and medication administration. This intervention supports all subsequent emergency treatments.
D. Insert an indwelling urinary catheter. A catheter may be necessary for monitoring urine output as a sign of perfusion, but this is not the first action in a trauma situation where immediate stabilization is the priority.

Correct Answer is B
Explanation
A. Open the outermost flap of the sterile kit toward the body. The outermost flap should always be opened away from the body first to prevent contamination of the sterile field by leaning over it. This helps maintain sterility by minimizing the risk of contact.
B. Place the cap from the solution sterile side up on a clean surface. Placing the cap sterile side up prevents the sterile inner surface from touching the contaminated surface and helps maintain aseptic technique during solution use.
C. Place the sterile dressing within 1.25 cm (0.5 in) of the edge of the sterile field. The outer 2.5 cm (1 inch) border of a sterile field is considered contaminated. Placing items too close to the edge increases the risk of contamination and compromises the field's sterility.
D. Set up the sterile field 5 cm (2 in) below waist level. Any sterile item held or placed below waist level is considered contaminated. The sterile field must always be maintained above waist level to preserve asepsis.
Correct Answer is B
Explanation
A. Premature atrial complexes. These are early electrical impulses originating in the atria that cause premature heartbeats, but they do not consistently lengthen the P-R interval. The P-R interval usually remains within normal limits unless another condition is present.
B. First-degree atrioventricular (AV) block. A constant P-R interval longer than 0.20 seconds (normal range: 0.12–0.20 seconds) is characteristic of a first-degree AV block. A P-R interval of 0.35 seconds indicates a prolonged conduction delay through the AV node, consistent with this dysrhythmia.
C. Complete heart block. In complete (third-degree) heart block, there is no consistent relationship between P waves and QRS complexes, and the P-R interval is not constant. This is not consistent with a stable, prolonged P-R interval.
D. Atrial fibrillation. Atrial fibrillation is marked by irregularly irregular rhythm and absent, unidentifiable P waves, not a consistent P-R interval. The atria are quivering, not contracting in a coordinated way.
