A teenage client is diagnosed with acne. Which assessment finding supports the existence of acne?

A. Ulcers: Ulcers are deep, open lesions that extend through the skin and may involve the dermis or deeper tissues. They are commonly associated with conditions such as pressure injuries, vascular insufficiency, infections, or severe inflammatory skin diseases. Acne typically presents with superficial inflammatory lesions rather than deep ulcerative tissue destruction. B. Pustules: Pustules are small, elevated lesions that contain purulent material and are a characteristic manifestation of inflammatory acne. Acne develops when hair follicles become obstructed by excess sebum and keratin, allowing bacterial proliferation, particularly Cutibacterium acnes. The inflammatory response leads to formation of pustules, papules, and sometimes nodules on the skin. C. Vesicles: Vesicles are small, fluid-filled blisters that contain clear serous fluid and are commonly associated with viral infections such as herpes simplex or varicella. They may also occur in allergic or inflammatory conditions like contact dermatitis. Acne lesions generally contain pus rather than clear fluid, making vesicles inconsistent with the typical presentation. D. Wheals: Wheals are transient, raised areas of skin edema often associated with urticaria or allergic reactions. They usually appear suddenly, are intensely pruritic, and resolve within hours as the allergic response subsides. Acne lesions persist longer and involve follicular inflammation rather than the temporary dermal swelling seen in wheals.
