On entering the room of a child in Buck traction, the nurse makes all of the following observations. Which observation requires a nursing intervention?

Child's heels are placed firmly against the foot of the bed.

Head of bed is elevated 20 degrees.

Ropes are on pulleys.

Weights are hanging freely.

Answer and Explanation

The Correct Answer is A

A. In Buck traction, the child’s heels should not be pressed against the foot of the bed, as this disrupts the traction force and may lead to skin breakdown or impaired circulation. The body must remain in proper alignment, and the child should be positioned so that traction can pull effectively.
B. Elevating the head of the bed up to 20 degrees is acceptable to promote comfort and prevent respiratory complications without affecting traction.
C. Ropes must be aligned properly on pulleys to ensure smooth traction force. This is a correct observation.
D. Weights should hang freely at all times to maintain consistent traction; this is the correct setup.

Correct Answer is ["38.3"]

Explanation

Use the conversion formula:
°C = (°F − 32) × 5⁄9

Substitute the values:
°C = (100.9 − 32) × 5⁄9
°C = 68.9 × 5⁄9
°C = 344.5 ÷ 9
°C ≈ 38.28

Rounded to one decimal place: 38.3°C

Final Answer:38.3 C
