Which of the following materials should not be used to secure a splint?

The correct answer is that cord should not be used to secure a splint because it may not provide the necessary support and stability needed for an injury. When securing a splint, it's essential to use materials that are both strong and capable of holding the splint firmly in place to prevent further injury and allow for effective healing. Bandages, wire, and tape are designed to stabilize and provide support, ensuring the splint remains securely in place while offering the necessary cushioning.

Cord, on the other hand, may lack the rigidity or sufficient surface area to anchor the splint effectively. It might not distribute pressure evenly and could lead to slippage or inadequate immobilization of the injured limb, increasing the risk of further injury or complications. Therefore, using appropriate materials like bandages, wire, or tape is crucial for proper splint application.
