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.

Correct Answer is D
Explanation
A. Placing the diaphragm against clothing can interfere with sound transmission. The stethoscope should be placed directly on the skin.
B. Earpieces should fit snugly in the ears to optimize sound conduction, rather than being loose.
C. Asking the client to hold their breath is not a standard technique for improving heart sound auscultation; it is more useful for breath sounds or murmurs.
D. "Eliminate distracting noises from the environment and ensure a snug fit with the ear pieces" is correct because background noise can interfere with auscultation, and a proper fit enhances sound transmission.
Correct Answer is D
Explanation
A. Documenting information directly from a textbook is incorrect because textbooks provide general guidelines, not client-specific data. The student's assessment findings should be based on the actual client’s condition.
B. Copying a previous nursing assessment is incorrect and unethical. Each assessment must be conducted independently to ensure accurate and up-to-date client care.
C. Documenting findings without confidence in their accuracy can lead to errors in client care. If the student is uncertain, verification is necessary before documentation.
D. Seeking clarification from a more experienced nurse is correct. If a student nurse is unsure of their assessment findings, they should ask a preceptor or experienced nurse for guidance to ensure accuracy and safe client care.
