Which of the following instructions should a medical assistant provide regarding dressing changes to reduce the spread of infection?

Applying disinfectant directly to the dressing may not effectively eliminate bacteria or viruses already present on the skin or surrounding areas. Furthermore, this practice could potentially irritate the wound or compromise the dressing's integrity, which is crucial for preventing infection.

While iodine can be an effective antiseptic, using it on hands after changing a dressing does not address the critical need for hand hygiene before and during the procedure. The primary goal is to prevent contaminating the wound, which requires clean hands at the outset rather than post-application treatment.

Removing gloves before changing a dressing introduces a significant risk of contamination. Gloves serve as a barrier to protect both the healthcare provider and the patient from pathogens, and they should only be removed after the dressing change is complete and hands are thoroughly washed.
