Which material is NOT considered a rigid splint?

A rigid splint is designed to immobilize a body part to prevent further injury and provide support. Options such as metal strips, plastic boards, and rolled magazines are all materials that provide hard support, which is essential for the stabilization of broken bones or sprains.

In contrast, soft cloth does not provide the necessary rigidity to hold a limb in a fixed position. Instead, it can conform to the shape of the body part and does not prevent movement. Therefore, it does not serve the purpose of a rigid splint, which is to immobilize an injured area. Understanding the difference between rigid and soft supports is critical when applying first aid, as choosing the right type of splint can significantly affect the outcome of the injury being treated.
