Wound Care Certification Exam Wound Care Certification Pressure Injury Prevention 2

Question 1

A patient with a Stage 3 pressure injury has a BMI of 16.2 and serum albumin of 2.1 g/dL. Which nutritional intervention is MOST appropriate to support wound healing?

Accepted Answer

Provide 1.25–1.5 g/kg/day protein with caloric supplementation

Answer

Restrict protein to 0.8 g/kg/day to prevent renal strain

Answer

Initiate parenteral nutrition immediately regardless of GI function

Answer

Supplement with vitamin C only and recheck albumin in 4 weeks

Question 2

Which Braden Scale subscale directly measures the patient's ability to change and control body position?

Accepted Answer

Mobility

Answer

Moisture

Answer

Activity

Answer

Friction and Shear

Question 3

A critically ill patient in the ICU is placed on a vasopressor. How does this medication increase pressure injury risk?

Accepted Answer

It causes peripheral vasoconstriction, reducing tissue perfusion to bony prominences

Answer

It increases urine output, causing moisture-related skin breakdown

Answer

It raises core body temperature, accelerating skin breakdown

Answer

It causes agitation, increasing friction and shear forces

Question 4

Which support surface feature is MOST important for a patient with a pressure injury on the sacrum who is fully dependent for repositioning?

Accepted Answer

Alternating pressure to cyclically relieve pressure

Answer

Low air-loss capability to manage moisture

Answer

Lateral rotation to prevent pulmonary complications

Answer

High-density foam for cost-effective immobility support

Question 5

A nurse notices a dark purple discoloration on an intact heel of a patient admitted 6 hours ago. The area is firm and painful. This finding is BEST classified as:

Accepted Answer

Deep tissue pressure injury (DTPI)

Answer

Stage 1 pressure injury

Answer

Stage 2 pressure injury

Answer

Unstageable pressure injury

Question 6

When repositioning a patient to prevent pressure injury, which technique BEST reduces shear forces?

Accepted Answer

Using a draw sheet or friction-reducing slide sheet to move the patient

Answer

Elevating the head of bed to 90 degrees before turning

Answer

Rolling the patient directly across the mattress surface

Answer

Asking the patient to push with their heels during repositioning

Question 7

According to NPUAP/EPUAP guidelines, what is the MAXIMUM recommended head-of-bed elevation for patients at risk for pressure injuries, unless medically contraindicated?

Accepted Answer

30 degrees

Answer

15 degrees

Answer

45 degrees

Answer

60 degrees
