WGU D219 EVIDENCE BASED PRACTICE TASK 1
PREVENTING PRESSURE INJURIES ACTUAL
QUESTIONS AND CORRECT ANSWERS
◉ What does NPO mean?
Answer: Nothing by mouth
◉ What is TPN?
Answer: Total parenteral nutrition
◉ What should be evaluated to assess risk for pressure injuries?
Answer: Level of mobility, safety devices, neurovascular and
circulatory status, health problems, nutritional and hydration status,
laboratory results, incontinence, and current medications.
◉ Why is it important for nurses to perform skin assessments on
patients?
Answer: To prevent pressure injuries, which are associated with
increased treatment costs and diminished quality of life.
◉ What is the relationship between immobility and pressure
injuries?
,Answer: Pressure injuries develop due to prolonged pressure on the
skin and subcutaneous tissue from immobility.
◉ Which areas of the body are most susceptible to pressure injuries?
Answer: Sacrum, coccygeal areas, ischial tuberosities, greater
trochanter, heel, knee, malleolus, medial condyle of the tibia, fibular
head, scapula, and elbow.
◉ What factors contribute to the development of pressure injuries in
patients with impaired sensory perception?
Answer: They may not feel discomfort from prolonged pressure and
thus do not change positions to relieve it.
◉ How does decreased tissue perfusion increase the risk of pressure
injuries?
Answer: It reduces circulation and nourishment to the skin and
subcutaneous tissue, making them more susceptible to injury.
◉ What nutritional factors can contribute to pressure injuries?
Answer: Nutritional deficiencies, anemias, and metabolic disorders
can predispose patients to pressure injuries.
◉ What serum albumin level is associated with increased risk of
pressure injuries?
, Answer: Levels less than 3 g/dL.
◉ What is the difference between friction and shear in the context of
pressure injuries?
Answer: Friction is the force of rubbing surfaces together, while
shear occurs when tissue layers slide over one another, disrupting
microcirculation.
◉ What can prolonged moisture contact do to the skin?
Answer: It can cause maceration, irritation, and increase
vulnerability to pressure injuries.
◉ What are common microorganisms that can infect pressure
injuries?
Answer: Streptococci, staphylococci, Pseudomonas aeruginosa, and
Escherichia coli.
◉ What are gerontologic considerations regarding pressure
injuries?
Answer: Older adults have diminished skin elasticity, sensory
perception, and mobility, increasing their risk for pressure injuries.
◉ What nursing actions should be taken to assess skin for pressure
injuries?
