A nurse is assessing a client who is receiving treatment for psoriasis. Which of the following images depicts what the nurse should expect to observe?
A. Hypertrophic Scar
B. Dermatographia
C. Psoriatic Plaque
D. Folliculitis
The Correct Answer is C
Rationale:
A. Hypertrophic Scar: This image shows an abnormal, raised scar that is wider and more prominent than a normal healing scar, likely a hypertrophic scar which results from excessive collagen deposition during the healing process.
B. Dermatographia: This image displays urticarial (hive-like) lesions that appear as linear welts or swelling (wheals) on the skin of an arm. This is a common form of physical urticaria (hives). It is an exaggerated local skin response where light pressure, friction, or scratching results in localized vasodilation (redness) and edema (swelling/wheals) along the line of contact.
C. Psoriatic Plaque: This image displays a classic plaque-like lesion characteristic of Psoriasis. The characteristic features, a sharply demarcated, thickened (plaque), silvery-white scale covering a bright red, erythematous base. These plaques are often found symmetrically on the elbows, knees, scalp, and lower back.
D. Folliculitis: The lesions typically present as small, red bumps or pimples that may have a white or yellow center (a pustule) and usually center around a hair. The lesions in the image are discrete, erythematous (reddened), and scattered.

Correct Answer is D
Explanation
Rationale
A. Replace the NPWT dressing every 12 hours: NPWT dressings are typically changed every 48–72 hours, or sooner if the dressing is saturated or malfunctioning. Changing the dressing every 12 hours is excessive and can disrupt wound healing and increase infection risk.
B. Allow the wound to be open to air at least once per shift: Negative-pressure wound therapy requires a sealed environment to maintain suction and promote healing. Exposing the wound to air would compromise negative pressure, delay healing, and increase infection risk.
C. Shave the skin around the wound prior to applying the wound therapy device: Shaving can cause microabrasions and increase the risk of infection. Hair should be gently trimmed if necessary, but shaving is not recommended prior to applying NPWT dressings.
D. If client reports pain, decrease the suction to 75 mm Hg: Pain during NPWT can occur if suction pressure is too high. Reducing suction to 75 mm Hg helps minimize discomfort while maintaining therapeutic negative pressure. Adjusting suction appropriately promotes client comfort and adherence to therapy.
Correct Answer is C
Explanation
Rationale
A. Apply an abduction pillow to the legs: An abduction pillow is used to maintain proper hip alignment, especially after hip surgery, but it does not prevent plantar flexion contractures. Its purpose is to keep the lower extremities in proper abduction rather than address ankle mobility.
B. Use a trochanter roll: A trochanter roll helps prevent external rotation of the hip in immobile clients but does not influence ankle positioning. While important for hip alignment, it does not prevent plantar flexion contractures of the feet.
C. Use foot splints: Foot splints (or ankle-foot orthoses) maintain the feet in a neutral position, preventing plantar flexion and subsequent contracture. Regular use supports joint flexibility, reduces muscle shortening, and helps preserve functional mobility in immobile clients.
D. Prop the feet up: Elevating the feet may relieve pressure and promote circulation, but it can allow the toes to point downward and contribute to plantar flexion over time. This method is not effective in preventing contractures and may worsen the problem if used as the sole intervention.
