Step-by-step explanation:
The recommended length for a support bandage placed on a limb before applying a splint varies depending on the specific situation and the type of injury. However, a general guideline is to wrap the bandage around the limb at least two to three times, ensuring adequate coverage for optimal support.
For example, when applying a splint to a broken arm, the support bandage should start at the wrist and wrap upwards towards the elbow, covering the entire forearm. The bandage should be wrapped snugly, but not too tight to restrict blood flow. It should also extend beyond the edges of the splint to provide additional support to the limb.
