Certified Wound Ostomy Nurse (CWON) Practice Test

Which scenario is an indication for using NPWT?

1. Shallow wounds with minimal exudate

2. Deep wounds with large amounts of exudate

3. Aseptic surgical sites

4. Simple lacerations

The correct answer is: Deep wounds with large amounts of exudate

The scenario involving deep wounds with large amounts of exudate is an appropriate indication for the use of Negative Pressure Wound Therapy (NPWT). This form of therapy is specifically designed to manage complex wounds that are typically difficult to heal due to factors such as excess fluid and tissue factors present in deep wounds. NPWT helps to promote a moist wound environment, reduces edema, and enhances perfusion by applying negative pressure to the wound area. The vacuum effect created helps to remove excess exudate, which is crucial in managing wounds that produce significant drainage. In contrast, shallow wounds with minimal exudate do not require the intensive management that NPWT provides, and aseptic surgical sites typically do not present the complications that NPWT is designed to address. Simple lacerations also do not warrant the use of NPWT, as they are generally superficial and can be managed with basic wound care practices. Thus, NPWT is most beneficial in scenarios like deep wounds with large amounts of exudate, where its unique properties can facilitate improved healing outcomes.
