NPTE-PTA Integumentary Physical Therapy 3

Question 1

Negative pressure wound therapy (NPWT) promotes wound healing PRIMARILY by:

Applying subatmospheric pressure to remove exudate and stimulate granulation tissue

Answer

Elevating wound bed temperature to accelerate cellular metabolism

Answer

Delivering topical antibiotic solution continuously to the wound

Answer

Supplying supplemental oxygen directly to the wound bed

Answer

Conventional transcutaneous electrical nerve stimulation (TENS)

Answer

Interferential current (IFC)

Answer

Neuromuscular electrical stimulation (NMES)
