Final answer:
Option 3.
In Buck's extension traction, countertraction can be provided by using a footboard, an overhead trapeze, or slightly elevating the foot of the bed.
Explanation:
In Buck's extension traction, countertraction is provided to maintain the alignment and stability of the leg. The nurse can provide countertraction by using a footboard, which provides a surface for the patient to push against. This helps to prevent the leg from being pulled out of alignment by the traction force. Additionally, an overhead trapeze can be used to allow the patient to use their upper body strength to counteract the pull of traction. By holding onto the trapeze, the patient can maintain their position and prevent the leg from being displaced.
Slightly elevating the foot of the bed can also assist in providing countertraction. This helps to create an opposing force that counteracts the pull of traction. Elevating the head of the bed, on the other hand, does not provide countertraction in Buck's extension traction.
