Latest Update with complete solution
Question 1
Which statement best defines a pressure injury?
A. A skin tear caused by friction
B. A wound caused by infection of the skin
C. A wound caused by unrelieved pressure over a bony prominence resulting
in ischemia and tissue necrosis ✅
D. A superficial abrasion from shearing forces
Rationale:
Pressure injuries result from prolonged pressure that exceeds capillary closure
pressure, leading to ischemia, hypoxia, and tissue death.
Question 2
Which patient population has the highest lifetime risk of developing pressure
injuries?
A. Pediatric patients
B. Pregnant women
C. Patients with spinal cord injuries ✅
D. Athletes
Rationale:
SCI patients have impaired mobility and sensation, with lifetime risk reported as
high as 50–85%.
Question 3
What does the NPUAP staging system evaluate?
,ESTUDYR
A. Wound size and drainage
B. Infection severity
C. Wound depth and tissue destruction only ✅
D. Pain and odor
Rationale:
The NPUAP system classifies pressure injuries based on depth and tissue
involvement only; staging cannot be reversed.
Question 4
Which description is consistent with a suspected deep tissue injury (DTI)?
A. Shallow open ulcer with pink wound bed
B. Purple or maroon intact skin or blood-filled blister ✅
C. Exposed bone or tendon
D. Non-blanchable erythema only
Rationale:
DTI reflects underlying soft-tissue damage and may feel boggy, firm, warmer, or
cooler than surrounding tissue.
Question 5
Which finding is characteristic of a Stage 1 pressure injury?
A. Partial thickness skin loss
B. Non-blanchable redness of intact skin ✅
C. Exposed subcutaneous fat
D. Eschar covering wound base
Rationale:
Stage 1 involves intact skin with persistent redness that does not blanch under
pressure.

Question 6
Which feature defines a Stage 2 pressure injury?
A. Full-thickness tissue loss
B. Exposed bone or muscle
C. Partial-thickness loss with shallow open ulcer or blister ✅
D. Covered by slough
Rationale:
Stage 2 injuries involve partial-thickness dermal loss and often heal quickly if
managed properly.
Question 7
Which statement best describes a Stage 3 pressure injury?
A. Bone is visible
B. Full-thickness tissue loss with visible subcutaneous fat ✅
C. Only epidermal involvement
D. Intact skin with discoloration
Rationale:
Stage 3 involves full-thickness skin loss but does not expose bone, tendon, or
muscle.
Question 8
What differentiates a Stage 4 pressure injury from Stage 3?
A. Presence of erythema
B. Depth of blister
C. Exposed bone, tendon, or muscle ✅
D. Presence of slough only
Rationale:
Stage 4 injuries expose deeper structures and often include tunneling and
undermining.
