What should the EMR do to minimize the risk of infection at the site of injury?

Applying a sterile dressing is the best method for minimizing the risk of infection at the site of an injury. A sterile dressing acts as a barrier that protects the wound from external contaminants, such as bacteria and other pathogens that could lead to an infection. It provides a clean environment for the wound, which is crucial for promoting healing.

In addition to preventing contamination, a sterile dressing can also help absorb any exudate and protect the area from further injury. By maintaining a sterile environment around the wound, the risk of introducing or allowing growth of infectious agents is significantly reduced.

While other options can have their uses, they do not offer the same level of protection as a sterile dressing. For instance, covering a wound with a non-occlusive dressing may not prevent contaminants from entering. Keeping the wound open to air can expose it to bacteria and dirt, increasing the risk of infection. Using antibiotic ointment may seem beneficial, but it does not provide a barrier against potential pathogens unless combined with a sterile dressing. Therefore, the application of a sterile dressing is the most effective strategy to protect the injury site from infection.
