Certified Wound Ostomy Nurse (CWON) Practice Test

Which of the following is a type of antimicrobial dressing?

1. Hydrocolloid dressing

2. Cadexomer iodine

3. Gauze dressing

4. Transparent film dressing

The correct answer is: Cadexomer iodine

Cadexomer iodine is classified as an antimicrobial dressing due to its active component that provides antibacterial effects. This dressing utilizes iodine in a form that releases into the wound exudate, effectively reducing bacterial load and promoting healing in contaminated or infected wounds. The presence of iodine helps to eliminate a wide range of bacteria, making it particularly useful in managing infection risks. In contrast, hydrocolloid dressings primarily function by providing a moist wound environment and do not have intrinsic antimicrobial properties. Gauze dressings are versatile for various wound types but typically lack antimicrobial activity unless they are specifically treated or impregnated with an agent. Transparent film dressings serve as protective barriers that allow for moisture vapor permeability but do not impart antimicrobial benefits on their own.
