A nurse performs a skin screening for a client who has numerous skin lesions. Which lesion does the nurse evaluate first?

A. Beige freckles on the backs of both hands: Freckles (ephelides) are common benign pigmented lesions caused by increased melanin production, often related to sun exposure. They are typically uniform in color, small, and symmetric, and do not carry malignant potential. These findings do not require urgent evaluation compared to suspicious lesions. B. Irregular blue mole with white specks on the lower leg: This lesion raises concern for malignant melanoma based on the ABCDE criteria—irregular borders, color variation (blue with white areas), and atypical appearance. Such features suggest dysplastic or malignant changes, requiring immediate evaluation to rule out melanoma, which has high metastatic potential. C. Large cluster of pustules in the right axilla: Pustules suggest a localized bacterial skin infection such as folliculitis or hidradenitis suppurativa. While potentially uncomfortable and requiring treatment, these lesions are not typically life-threatening and do not take priority over possible malignant lesions. D. Thick, reddened papules covered by white scales.: These findings are characteristic of psoriasis, a chronic inflammatory skin condition involving rapid epidermal turnover and immune dysregulation. Although it may require management, it is not immediately life-threatening and does not carry the same urgency as a potentially malignant lesion.
