A client has sought care because they are concerned that a mole on the scalp may be skin cancer. Which finding would the nurse identify as being most suggestive of melanoma?
Solid, dark brown color
Asymmetric, irregular borders
Flat with silvery scales
Diameter of 3 mm
The Correct Answer is B
A. A solid, dark brown color alone is not necessarily indicative of melanoma. Melanomas often have multiple colors, including black, brown, blue, or red.
B. Asymmetric, irregular borders is correct. Melanoma lesions are often asymmetrical, with irregular, poorly defined borders. They also tend to have varied pigmentation and may change over time. The ABCDE rule (Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolution) is used to assess suspicious moles.
C. Flat with silvery scales describes psoriasis, not melanoma.
D. A diameter of 3 mm is smaller than the typical >6 mm size seen in melanoma.

B. Aneurysms, particularly abdominal aortic aneurysms, may present with a pulsatile mass and deep, dull pain rather than sharp pain and guarding.
C. Hernias can cause pain, but they typically present with a bulging mass that increases with straining, not sharp pain with reflex guarding.
