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?
Explanation & Rationale
A. This image shows well-demarcated, erythematous plaques covered with silvery-white scales—classic features of plaque psoriasis. These lesions typically appear on extensor surfaces like the elbows, knees, and scalp, and may itch or crack. B. This image shows a yellow crusting lesion which suggests impetigo or a secondary skin infection, not psoriasis. Impetigo typically presents with honey-colored crusts, caused by bacterial infection, usually. Psoriasis lesions are usually dry and scaly, not moist or oozing. C. This image shows red bumps on arm suggesting an allergic reaction, folliculitis, or possibly contact dermatitis. These are small papules often scattered or in clusters, and do not have the thick scaling seen in psoriasis. D. The fourth image shows linear striae-like marks likely striae distensae (stretch marks), unrelated to psoriasis. Stretch marks are atrophic, linear scars typically due to skin stretching from growth or weight changes. They lack inflammation, plaques, and scale—all key signs of psoriasis.
