What is the primary function of a dressing?

The primary function of a dressing is to cover and protect the wound while being sterile. This is essential for promoting healing and preventing infections. A sterile dressing minimizes the risk of contaminants entering the wound, which is crucial for preventing complications such as infections or delayed healing. By providing a barrier against pathogens and foreign substances, a sterile dressing helps to maintain a favorable environment for wound healing.

While securing the wound is an important aspect of dressing application, it is not the primary function. A dressing must also serve to cover and protect the wound effectively. Options suggesting non-sterile coverings or ventilation of the wound do not align with the fundamental purpose of a dressing, which emphasizes sterility and protection.
