Question 1

Negative Pressure Wound Therapy (NPWT) promotes wound healing primarily by:

Accepted Answer

Removing excess exudate and promoting granulation tissue formation

Answer

NPWT uses sub-atmospheric pressure to remove exudate, reduce edema, and stimulate angiogenesis and granulation tissue formation.

Question 2

Which of the following is a contraindication for Negative Pressure Wound Therapy (NPWT)?

Accepted Answer

Wound with untreated osteomyelitis

Answer

NPWT is contraindicated in wounds with untreated osteomyelitis because negative pressure can spread infection into bone or surrounding tissue.

Question 3

The standard negative pressure setting for NPWT in most clinical applications is:

Accepted Answer

-75 to -125 mmHg

Answer

Most NPWT protocols use -75 to -125 mmHg, with -125 mmHg being the most commonly used therapeutic pressure.

Question 4

Hyperbaric Oxygen Therapy (HBOT) for chronic wounds works by:

Accepted Answer

Delivering high concentrations of oxygen under increased atmospheric pressure to hypoxic tissue

Answer

HBOT increases dissolved oxygen in plasma under pressure, delivering oxygen to hypoxic wound tissue where hemoglobin-bound oxygen cannot reach.

Question 5

Biological skin substitutes used in chronic wound care are best indicated for:

Accepted Answer

Full-thickness wounds failing to progress with conventional therapy

Answer

Bioengineered skin substitutes are indicated for non-infected, clean full-thickness wounds that have not healed adequately with standard wound care.
