The nurse is caring for a young adult who reports uncontrolled acne vulgaris. Which pathological findings should the nurse observe on inspection of skin areas commonly affected in acne vulgaris?

A) Small, skin-colored, pedunculated papules in areas of skin folds and on other areas as skin tags: This description is more characteristic of acrochordons (skin tags), which are benign skin growths often found in skin folds. Skin tags are typically not associated with acne vulgaris. B) Hyperpigmented areas that vary in form and color and are slightly elevated from the skin: This description may be indicative of post-inflammatory hyperpigmentation, which can occur after resolution of acne lesions. However, it does not represent the primary pathological findings observed in acne vulgaris. C) Hyperactive sebaceous areas forming comedones, papules, pustules on the face, neck, and upper back: Correct. Acne vulgaris is characterized by hyperactive sebaceous glands, leading to the formation of comedones (blackheads and whiteheads), papules, and pustules. These lesions commonly occur on the face, neck, and upper back due to the high density of sebaceous glands in these areas. D) Sharply demarcated silvery scaling plaques with underlying redness on the elbows and knees: This description is more indicative of psoriasis, a chronic autoimmune skin condition characterized by silvery scaling plaques and inflammation. Psoriasis typically affects extensor surfaces such as the elbows and knees, rather than the areas commonly affected by acne vulgaris.
