Certified Wound Ostomy Nurse (CWON) Practice Test

For what purpose are cadexomer iodine dressings used?

1. To completely sterilize wounds

2. To control bacterial loads without damaging good cells

3. To provide moisture to the wound

4. To cover the wound in all conditions

The correct answer is: To control bacterial loads without damaging good cells

Cadexomer iodine dressings are specifically designed to manage bacterial loads in wounds while maintaining the integrity of surrounding healthy tissue. These dressings release iodine in a controlled manner, allowing for the antimicrobial properties of iodine to act without harming the vital cells necessary for wound healing. By effectively reducing the presence of bacteria, they help to decrease the risk of infection while promoting a healthier wound environment. While there are other considerations in wound care, such as moisture balance and coverage, cadexomer iodine dressings are distinct in their primary function of antimicrobial action. Other options may suggest purposes like total sterilization, moisture provision, or covering wounds under all conditions, but these do not align with the specific therapeutic intent of cadexomer iodine dressings.
