What nursing action will significantly decrease the risk of serious complications for a child in Bryant's traction?

A. Restricting movement can cause discomfort and is not the priority intervention to prevent serious complications. B. Bandages should be snug but not tight, as tight wrapping can impair circulation. C. In Bryant's traction, the buttocks should be slightly elevated off the bed, not resting on it, to maintain proper traction. D. Neurovascular checks done frequently are critical in Bryant’s traction to assess circulation, sensation, and movement. These checks help detect early signs of complications like compartment syndrome or impaired perfusion, making this the most important action.
