Correct Answer is B
Explanation
A. Using elbows to reposition could cause discomfort or skin damage. Clients in skeletal traction should avoid shifting weight in ways that might disrupt the alignment of the traction apparatus.
B. Providing a trapeze bar helps clients reposition themselves and adjust their position while maintaining the traction. It allows for safer and more effective movement while in traction.
C. Removing the weights disrupts the traction and could affect the alignment and healing process. Weights should only be removed by a healthcare professional when necessary and per specific guidelines.
