SMS Pressure Injury Prevention and Skin Integrity

Question 1

According to the National Pressure Injury Advisory Panel (NPIAP), a Stage 2 pressure injury is characterized by:

Accepted Answer

Partial-thickness skin loss with exposed dermis

Answer

Stage 2 pressure injuries involve partial-thickness skin loss with exposed dermis; the wound bed is pink or red and moist.

Question 2

Which seated position places the highest pressure on the ischial tuberosities?

Accepted Answer

Upright 90-degree hip flexion without cushion

Answer

An upright 90-degree seated position without a pressure-relieving cushion concentrates the highest interface pressures directly on the ischial tuberosities.

Question 3

Shear forces in seating contribute to pressure injury development primarily by:

Accepted Answer

Causing tissue deformation and disrupting microcirculation in deeper tissues

Answer

Shear forces cause mechanical deformation of deeper tissues, disrupting microcirculation and accelerating ischemia even at lower interface pressures.

Question 4

A pressure mapping system in seating evaluation is used to:

Accepted Answer

Visualize and quantify interface pressure distribution between the client and the seating surface

Answer

Pressure mapping provides a visual map of interface pressure distribution to help identify high-pressure areas and evaluate the effectiveness of different cushion options.

Question 5

Which client population is at HIGHEST risk for seated pressure injuries?

Accepted Answer

Clients with spinal cord injury, insensate skin, and limited mobility

Answer

Clients with spinal cord injury have insensate skin, limited mobility to shift weight, and often circulatory impairment, placing them at the highest risk for seated pressure injuries.
