ATI Physical Assessment Practice Test

A characteristic that indicates a potential malignant skin lesion is an irregular border. Malignant lesions often have edges that are not smooth, which can appear jagged or blurred. This irregularity may be a sign of the lesion's invasive characteristics and its potential to spread beyond the original site.

Additionally, asymmetrical shape is another crucial indicator of skin lesions that may be cancerous. In general, benign lesions tend to be symmetrical, while malignant lesions may exhibit uneven growth patterns, leading to an asymmetrical appearance.

The size of a pencil eraser is relatively small and may not be alarming on its own; however, larger lesions or changes in existing moles can warrant further examination. Color uniformity suggests that there is consistent pigmentation throughout the lesion, which is typically a sign of a benign lesion rather than malignancy.

Understanding these characteristics—irregular shapes, borders, and asymmetry—can help in the accurate assessment of skin lesions and the decision to pursue further evaluation or intervention.
