A nurse is observing a newly licensed nurse who is performing a focused skin assessment on a client who reports a skin condition. Which of the following questions by the newly licensed nurse requires intervention?

Choice A reason:
Squamous cell carcinoma typically presents as a rough, scaly, red patch, open sore, or raised growth with a central depression, often on sun-exposed areas of the body. While it can appear as a lesion that varies in color, it is not commonly associated with a nevus that has increased in size.

Choice B reason:
Malignant melanoma is associated with changes in preexisting nevi, such as an increase in size and variations in color. It often appears as a mole that changes in color, size, or feel and may have irregular edges. The description of the lesion provided by the client is characteristic of malignant melanoma, making this the correct diagnosis.

Choice C reason:
Kaposi's sarcoma is a cancer that forms in the lining of blood and lymph vessels and typically appears as patches of abnormal tissue on the skin or mucous membranes. These lesions are usually red or purple and look similar to bruises¹. They are not typically described as nevi that increase in size or lesions that vary in color.

Choice D reason:
Basal cell carcinoma often appears as a slightly transparent bump on the skin, though it can take other forms. It usually presents as a pearly white or pink bump on white skin, or a brown or black bump on darker skin, and is most often found on sun-exposed areas. It is not typically associated with a nevus that has increased in size or an irregularly shaped lesion that varies in color.

Choice A reason:
The statement about eating a high fiber diet reducing the risk for developing skin cancer is misleading. While a high fiber diet has many health benefits, there is no direct evidence that it significantly reduces the risk of skin cancer. Skin cancer prevention primarily focuses on protecting the skin from excessive sun exposure and avoiding ultraviolet (UV) light sources.

Choice B reason:
Avoiding the use of tanning booths is correct advice. Tanning booths emit UV radiation, which can increase the risk of skin cancer, including melanoma, the deadliest form of skin cancer. The use of tanning beds is strongly discouraged by health professionals.

Choice C reason:
Using sunscreen even on cloudy days is also correct. UV rays can penetrate through clouds, and sun protection is necessary regardless of the weather to reduce the risk of skin cancer. Sunscreen should be applied to all exposed skin and reapplied regularly, especially after swimming or sweating.

Choice D reason:
Checking the skin monthly for any changes is an important part of skin cancer prevention. Early detection of changes in moles or new skin growths can lead to early diagnosis and treatment, which is crucial for a better prognosis. This practice should be encouraged as part of routine self-care.
