Final answer:
Light skin pigmentation is a risk factor for skin cancer due to reduced melanin protection against UV light, while psoriasis is not directly related to skin cancer risk. Screening for skin cancer typically involves a visual inspection of the skin.
Step-by-step explanation:
The nurse should include the following risk factors in the teaching regarding skin cancer: having light skin pigmentation, because individuals with lighter skin are at a higher risk of developing skin cancer due to less melanin, which offers some protection against UV radiation. A history of frostbite is less directly related to skin cancer but may indicate skin that has been damaged and could potentially be more vulnerable. However, psoriasis is an autoimmune condition and not directly a risk factor for skin cancer, though individuals with psoriasis may have an increased risk due to treatments involving UV light exposure.
Screening for Skin Cancer
One way that screening for skin cancer is performed is through a visual inspection of the skin for any unusual moles or growths that could indicate malignancy.
