WGU D219 EVIDENCE BASED PRACTICE TASK 1
PREVENTING PRESSURE INJURIES
COMPREHENSIVE TASK PAPER QUESTIONS
AND SOLUTIONS
◉ What is the role of serum prealbumin levels in assessing
nutritional status?
Answer: They are sensitive indicators of protein deficiency and can
help assess risk for pressure injuries.
◉ What is a sinus tract in relation to pressure injuries?
Answer: An area of destroyed tissue extending from the edge of a
wound, creating dead space susceptible to abscess formation.
◉ What is the impact of spastic muscles and paralysis on pressure
injury risk?
Answer: They increase vulnerability to pressure injuries related to
friction and shear.
◉ What is the consequence of impaired skin barrier due to pressure
injuries?
Answer: It allows for invasion by microorganisms, leading to
potential infections.
, ◉ What is the relationship between anemia and pressure injuries?
Answer: Anemia decreases the blood's oxygen-carrying ability,
increasing the risk for pressure injuries.
◉ What is the effect of mechanical forces like friction and shear on
pressure injuries?
Answer: They contribute to the development of pressure injuries by
disrupting microcirculation and causing tissue damage.
◉ What are the signs of deep tissue damage in pressure injuries?
Answer: Slow development of damage, possibly presenting as a
sinus tract.
◉ What should a nurse document when a pressure injury is seen?
Answer: The size and location of the injury, its severity using a
grading system, and a description of the site.
◉ What does the appearance of purulent drainage or foul odor
indicate?
Answer: It suggests an infection in the pressure injury.
◉ What serious conditions can result from an extensive pressure
injury?
