What is NOT a function of dressings and bandages?

The function of dressings and bandages primarily revolves around protecting the wound and managing injuries. While immobilization of the injury can sometimes be a secondary consequence of how a dressing or bandage is applied, it is not their primary function. Dressings are mainly designed to cover an open wound to prevent contamination, while bandages are intended to secure dressings in place, protect the area from further injury, and help control external bleeding.

The primary roles of dressings include prevention of contamination, ensuring that the wound is sealed from dirt and bacteria, and protection from further injury by providing a barrier. Controlling external hemorrhage is also a critical function of both dressings and bandages, as they can help apply pressure to a bleeding site effectively.

In summary, while immobilization may occur depending on the type of injury and method of application, it does not represent the fundamental purpose of dressings and bandages, making it the option that is not a function of these medical supplies.
