Which device provides negative pressure wound therapy to promote granulation tissue?

• A. Nasal cannula
• B. TED Hose
• C. Foley catheter
• D. Wound VAC provides negative pressure wound therapy to promote granulation tissue

Answer: (D)

Negative pressure wound therapy uses a sealed dressing connected to a pump to apply controlled suction to a wound. The Wound VAC is the device that provides this therapy, promoting granulation tissue by removing excess fluid, reducing edema, improving blood flow, and helping wound edges come together. The other devices don’t apply negative pressure to a wound: a nasal cannula delivers supplemental oxygen, TED Hose are compression stockings to support venous return, and a Foley catheter drains urine.
