The nurse understands that negative-pressure wound therapy may be used in the treatment of partial-thickness burn wounds to do which of the following?

Correct Answer: B

Rationale: Negative-pressure wound therapy can be used to treat grafts or partial-thickness burns by decompressing edematous interstitial spaces that enhance local perfusion, optimizing wound healing. This therapy also provides a moist wound-healing environment. The system is closed and may reduce the risk of infection but may not prevent infection. Patients are less mobile because the system needs an electrical source to function. Wound drainage is quantified by using the negative-pressure wound therapy system, but this is not a primary indication for the therapy.

Correct Answer: A

Rationale: Syme amputation (modified ankle disarticulation amputation) is performed most frequently for extensive foot trauma and produces a painless, durable extremity end that can withstand full weight-bearing. Therefore, each of the other teaching statements is incorrect.

Correct Answer: C

Rationale: Inadequate fracture immobilization can delay or prevent union. A short-term vitamin D deficiency would not likely prevent bone union. VTE is a serious complication but would not be a cause of nonunion. Similarly, bleeding would not likely delay union.

Correct Answer: D

Rationale: Reduced immune cell activity in aging slows wound healing.

Correct Answer: B

Rationale: Pain during hydrotherapy is procedural pain, caused by the specific activity of wound care, requiring targeted pain management.
