Which dressing is most appropriate for a wound with heavy, foul-smelling, greenish exudate?

1. Hydrocolloid

2. Transparent film

3. Calcium alginate

4. Foam

The correct answer is: Calcium alginate

A dressing that is most appropriate for a wound with heavy, foul-smelling, greenish exudate should have properties that manage exudate effectively and address potential infections. Calcium alginate is particularly suited for this type of wound because it is highly absorbent, making it ideal for managing significant amounts of exudate. Additionally, calcium alginate dressings are derived from seaweed and can help create a moist environment that is conducive to wound healing. They also facilitate autolytic debridement, which aids in the removal of necrotic tissue and debris, thereby addressing foul-smelling drainage that might accompany an infected wound. This type of dressing also has antimicrobial properties, which can help combat infection, making it suitable for a wound with potentially foul-smelling exudate indicative of infection. The gel-like consistency formed when the alginate comes into contact with exudate also helps to prevent further tissue damage and supports the healing process. In contrast, other dressing options like hydrocolloids, transparent films, and foams might not be as effective in scenarios of heavy exudate or infection. Hydrocolloid dressings may not absorb enough moisture, while transparent films are typically used for shallow or dry wounds. Foam dressings can
