Question 1

What is the PRIMARY cause of pressure injuries (pressure ulcers)?

Accepted Answer

Prolonged pressure that restricts blood flow to skin

Answer

Pressure injuries are caused by sustained pressure that reduces or cuts off blood supply to the skin and underlying tissue, leading to ischemia and tissue death.

Question 2

Which bony prominence is at the HIGHEST risk for pressure injury development?

Accepted Answer

Sacrum and coccyx

Answer

The sacrum and coccyx (tailbone area) are the most common sites for pressure injuries because they bear substantial weight when a person lies in bed or sits.

Question 3

A Stage 1 pressure injury appears as:

Accepted Answer

Non-blanchable redness of intact skin

Answer

A Stage 1 pressure injury is characterized by non-blanchable erythema (redness that does not turn white when pressed) on intact skin, indicating early tissue damage.

Question 4

What does 'blanchable' redness mean?

Accepted Answer

The skin turns white when pressure is applied, then returns to red

Answer

Blanchable redness temporarily turns white when pressure is applied and returns to red when released, indicating intact capillary blood flow. Non-blanchable redness suggests pressure injury.

Question 5

Which of the following is a risk factor for pressure injury development?

Accepted Answer

Urinary incontinence

Answer

Urinary incontinence exposes the skin to moisture and ammonia, which break down skin integrity and increase the risk of pressure injuries.
