A client tells a nurse that "this dark spot on my left shoulder has gotten bigger, changed from a reddish to a brownish color, and used to be flat but is now like a small bump." The nurse knows that these findings may suggest

A. Changes in size, color, and shape of a mole or spot, especially with the development of a bump, could be indicative of skin cancer, particularly melanoma. B. That there is nothing to be concerned about. Given the changes in the spot's appearance, this is a concerning sign and requires further investigation, so this choice is not correct. C. Wounds typically heal without such significant color and shape changes, so this is unlikely to be a normal healing process. D. A secondary lesion is caused by trauma or infection, but the described changes are more concerning for a potential primary skin malignancy, such as melanoma.
