Which of the following is a type of antimicrobial dressing?

1. Cadexomer iodine

2. Hydrocolloid dressing

3. Foam dressing

4. Transparent film dressing

The correct answer is: Cadexomer iodine

Cadexomer iodine is a type of antimicrobial dressing that contains iodine in a gel form. This dressing is designed to slowly release iodine over time, which helps to reduce bacterial load in the wound, management of exudate, and promotes a moist wound healing environment. Iodine has broad-spectrum antimicrobial properties, effective against a variety of microorganisms, which makes cadexomer iodine particularly useful in treating infected or at-risk wounds. The other options do not possess the same antimicrobial properties. Hydrocolloid dressings are mainly used for maintaining a moist environment and might facilitate autolytic debridement, but they do not inherently have antimicrobial features. Foam dressings are designed to absorb exudate and provide cushioning but do not have antimicrobial properties. Transparent film dressings are primarily used to provide a barrier against moisture and bacteria while allowing for visualization of the wound but lack inherent antimicrobial actions as well. Thus, cadexomer iodine distinguishes itself as an effective option in the realm of antimicrobial dressings.
