Correct answer: C) Foul odor from the wound

Rationale: Foul odor from the wound may indicate an infection or necrotic tissue, which can impair wound healing and increase the risk of sepsis. The nurse should notify the provider and obtain a wound culture if indicated.

Incorrect options:

A) Serous drainage from the wound - This is a normal finding, as serous drainage is clear and watery and indicates fluid leakage from damaged capillaries.

B) Erythema around the wound edges - This is a normal finding, as erythema (redness) around the wound edges indicates inflammation and increased blood flow to the area, which are part of the normal healing process.

D) Granulation tissue in the wound bed - This is a normal finding, as granulation tissue is pink or red and indicates new tissue growth and blood vessel formation in the wound.

Correct answer: D) Silver dressing

Rationale: Silver dressing is a type of antimicrobial dressing that contains silver ions, which have bactericidal properties and can prevent or treat wound infections. Silver dressing can also reduce pain, inflammation, and odor from the wound. Silver dressing is often used for burn injuries, as they are at high risk of infection due to loss of skin integrity and exposure to pathogens.

Incorrect options:

A) Hydrocolloid dressing - This is a type of occlusive dressing that forms a gel-like substance when in contact with wound exudate. Hydrocolloid dressing can promote moist wound healing, reduce pain, and protect the wound from contamination. However, it is not suitable for infected wounds or wounds with heavy drainage, as it can trap bacteria and fluid in the wound and cause maceration of the surrounding skin.

B) Hydrogel dressing - This is a type of dressing that contains water or glycerin and provides moisture to dry wounds. Hydrogel dressing can hydrate necrotic tissue, reduce pain, and facilitate autolytic debridement. However, it is not suitable for wounds with heavy drainage, as it can increase fluid loss and cause maceration of the surrounding skin.

C) Alginate dressing - This is a type of dressing that contains seaweed fibers and forms a gel-like substance when in contact with wound exudate. Alginate dressing can absorb large amounts of fluid, fill dead space in the wound, and facilitate hemostasis. However, it is not suitable for dry wounds or wounds with minimal drainage, as it can dehydrate the wound and cause trauma to granulation tissue when removed.

Correct answer: A) Decreased edema in the wound area

Rationale: Decreased edema in the wound area indicates that NPWT is effective, as NPWT applies negative pressure (suction) to the wound, which removes excess fluid, reduces swelling, and improves blood circulation to the area.

Incorrect options:

B) Increased drainage from the wound - This indicates that NPWT is ineffective, as NPWT should reduce drainage from the wound by removing excess fluid and promoting wound closure.

C) Decreased granulation tissue in the wound bed - This indicates that NPWT is ineffective, as NPWT should increase granulation tissue in the wound bed by stimulating cell proliferation and angiogenesis.

D) Increased eschar formation on the wound surface - This indicates that NPWT is ineffective, as NPWT should decrease eschar formation on the wound surface by facilitating debridement and removing necrotic tissue.
