What should be padded and tied on the injured side when using a large arm sling?

When using a large arm sling, the correct approach is to pad and tie on the injured side the knot of the sling. This is important for several reasons.

First, securing the knot on the injured side helps to provide stability and support for the injured arm while preventing unnecessary movement, which could exacerbate the injury. Padding around the knot creates a cushioning effect, reducing friction against the skin and minimizing discomfort for the patient.

Moreover, placing the knot on the injured side allows for a more effective distribution of weight and helps to keep the arm in a comfortable position, promoting better healing. This technique is especially vital in scenarios where the injury involves fractures or soft tissue damage, as proper immobilization can significantly affect recovery time and overall treatment success.

In contrast, the other options do not focus on the primary goal of immobilizing and protecting the injured arm appropriately. The strap of the sling, shoulder padding, and elbow support play roles in distribution and comfort, but they do not address the crucial aspect of knot placement, which is key to maintaining stability and ensuring effective immobilization of the injured area.
