Question 1

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

Accepted Answer

Applying subatmospheric pressure to remove exudate and stimulate granulation tissue

Answer

NPWT applies controlled subatmospheric pressure through a foam dressing to remove excess exudate, reduce wound edema, and mechanically stimulate granulation tissue formation.

Question 2

Which type of electrical stimulation has the MOST research evidence supporting its use for wound healing promotion?

Accepted Answer

High-voltage pulsed current (HVPC)

Answer

High-voltage pulsed current (HVPC) has the strongest evidence base for wound healing, demonstrating improvements in tissue perfusion, antimicrobial effects, and granulation tissue formation.

Question 3

A PTA uses therapeutic ultrasound on a deep wound cavity (approximately 4 cm depth). Which frequency is MOST appropriate?

Accepted Answer

1 MHz

Answer

1 MHz ultrasound penetrates to depths of 3–5 cm, making it appropriate for deep wounds, while 3 MHz is used for superficial structures within 1–2 cm of the skin surface.

Question 4

The standard clinical method for measuring wound dimensions requires length to be measured along which axis?

Accepted Answer

Along the head-to-toe (craniocaudal) axis of the body

Answer

Standard wound measurement defines length along the head-to-toe (craniocaudal) body axis and width perpendicular to it (side to side), ensuring consistent serial measurements across clinicians.

Question 5

Which wound characteristic represents a PRIMARY contraindication to pulsed lavage wound irrigation?

Accepted Answer

Exposed vasculature or tendons without protective paratenon

Answer

Exposed vasculature or tendons without the protective paratenon are primary contraindications to pulsed lavage because pressurized irrigation can cause mechanical damage to these delicate structures.
