What action should you take if the injured area feels cold after immobilizing?

When the injured area feels cold after immobilization, loosening the splint is the appropriate action to take. Coldness in an extremity may indicate compromised circulation, which can occur if the splint is too tight and is restricting blood flow. By loosening the splint, you relieve the pressure on the blood vessels, potentially restoring circulation to the area. This action helps ensure that the tissue receives adequate blood supply, which is vital for healing and preventing further complications.

Applying heat to the area does not address the underlying issue of compromised blood flow and could worsen the situation. Reapplying the splint tighter would likely exacerbate the problem of restricted circulation, leading to further coldness and potential tissue damage. Keeping the splint in place without adjusting it does not sufficiently address the signs of decreased circulation and may put the individual at risk for additional harm. Therefore, loosening the splint is a critical step in ensuring the injured area maintains proper blood flow and warmth.
