A nurse is applying a dressing to a wound that has moderate to heavy exudate. Which of the following types of dressing would be most appropriate for this wound?

Transparent film

Hydrogel

Foam

Alginate

Answer and Explanation

The Correct Answer is D

Answer: D

Alginate dressing is a type of dressing that is made from seaweed fibers and is highly absorbent. It is suitable for wounds that have moderate to heavy exudate, as it can absorb up to 20 times its weight in fluid. It also forms a gel-like substance when in contact with wound fluid, which creates a moist environment that facilitates wound healing and autolytic debridement.

C. Foam dressing is a type of dressing that is made from polyurethane or silicone and is moderately absorbent. It is suitable for wounds that have light to moderate exudate, as it can absorb up to four times its weight in fluid. It also provides cushioning and insulation for the wound, and prevents bacterial contamination.

B. Hydrogel dressing is a type of dressing that is made from water or glycerin and is minimally absorbent. It is suitable for wounds that have minimal exudate, as it can only absorb up to 10% of its weight in fluid. It also provides hydration and cooling for the wound, and promotes autolytic debridement and granulation tissue formation.

A. Transparent film dressing is a type of dressing that is made from polyurethane and is non-absorbent. It is suitable for wounds that have no exudate, as it does not absorb any fluid. It also provides protection and visualization for the wound, and allows gas exchange and moisture vapor transmission.

Correct Answer is B

Explanation

Answer: B

The wound has decreased in drainage is an outcome that would indicate that NPWT is successful. NPWT is a type of therapy that uses a vacuum device to apply negative pressure to the wound, which removes excess fluid, debris, and infectious material from the wound bed. This reduces edema, inflammation, and bacterial load, and promotes blood flow, oxygenation, and granulation tissue formation.

A. The wound has increased in size is an outcome that would indicate that NPWT is unsuccessful or harmful. NPWT should not cause wound enlargement, as this may indicate tissue damage, infection, or poor healing.

C. The wound has increased in pain is an outcome that would indicate that NPWT is unsuccessful or harmful. NPWT should not cause excessive pain, as this may indicate tissue damage, infection, or poor healing.

D. The wound has decreased in granulation tissue is an outcome that would indicate that NPWT is unsuccessful or harmful. NPWT should promote granulation tissue formation, as this indicates healthy wound healing.

A. Change the dressing every 12 hours or as needed. B. Irrigate the wound with normal saline before applying the dressing. C. Ensure that the dressing is sealed and airtight around the wound. D. Clamp the tubing when ambulating or repositioning the client.

Correct Answer is C

Explanation

Correct answer: C) Ensure that the dressing is sealed and airtight around the wound.

Rationale: Negative pressure wound therapy (NPWT) is a device that applies

subatmospheric pressure to the wound bed, which promotes granulation tissue formation, removes excess fluid and debris, and reduces edema and bacterial colonization. The nurse should ensure that the dressing is sealed and airtight around the wound to maintain negative pressure and prevent air leaks.

Incorrect options:

A) Change the dressing every 12 hours or as needed. - This is not recommended for NPWT, as frequent dressing changes can disrupt wound healing and increase the risk of infection. The nurse should change the dressing every 48 to 72 hours or as prescribed by the provider.

B) Irrigate the wound with normal saline before applying the dressing. - This is not recommended for NPWT, as irrigation can introduce bacteria into the wound and interfere with negative pressure. The nurse should clean the wound with normal saline or sterile water and pat it dry gently before applying the dressing.

D) Clamp the tubing when ambulating or repositioning the client. - This is not recommended for NPWT, as clamping can interrupt negative pressure and cause tissue damage. The nurse should secure the tubing to prevent kinking or dislodgment and keep the device below the level of the wound when ambulating or repositioning the client.
