The primary purpose of using sterile dressings is to secure the wound and keep it clean from dirt and bacteria. Sterile dressings are specifically designed to create a barrier that prevents contaminants from entering the wound, which is crucial for preventing infection. By keeping the area free from harmful pathogens, sterile dressings promote healing and protect the wound from external irritants and damage.

While other functions, such as absorbing blood and fluids, and providing warmth can be secondary benefits of certain types of dressings, the main intent of using sterile dressings is to maintain a clean environment for the wound to facilitate optimal healing conditions. Immobilization is also not the primary consideration with sterile dressings; rather, that is usually addressed with other methods or materials intended for immobilizing injured areas. Thus, the explanation for the choice focuses on the essential role sterile dressings play in wound care and their effectiveness in maintaining cleanliness in the healing process.
