The nurse is caring for an 11-year-old patient being treated for a fractured right femur with balanced suspension traction with a Thomas splint and Pearson attachment.
- A. What should the nurse do if the patient’s left leg is externally rotated?
- B. Place a trochanter roll on the outer aspect of the thigh.
- C. Perform resistive range of motion of the left leg.
- D. Adduct and internally rotate the left leg.
- E. Instruct the patient to maintain the left leg in a neutral position.
Correct Answer: A
Rationale: A trochanter roll placed on the outer aspect of the thigh prevents external rotation by holding the hip in a neutral position and maintaining normal leg alignment. Resistive exercises, manual repositioning, or instructing the patient to maintain position are less effective, as they do not provide sustained support to prevent rotation.

- A. Lumbar puncture
- B. CT scan

The nurse is caring for a newborn with tracheoesophageal fistula. Which nursing diagnosis is a priority?
- A. Risk for dehydration
- B. Ineffective airway clearance
- C. Altered nutrition
- D. Risk for injury
