A nurse is assessing a client at a dermatology clinic. Which of the following findings places the client at risk for developing malignant melanoma?

Choice A reason:
Determining the client's understanding of the procedure is important as it ensures informed consent and can help alleviate anxiety. However, while this is a necessary part of preoperative care, it may not be the immediate priority¹.

Choice B reason:
Establishing the need for psychological support is a valuable aspect of holistic care. It addresses the client's emotional well-being and can improve overall satisfaction with the surgical experience. Nonetheless, it is not the primary focus of the preoperative assessment².

Choice C reason:
Identifying possible surgical risks is the priority in a preoperative assessment. This includes evaluating the client's medical history, current health status, and any factors that could increase the risk of complications during or after surgery. A thorough risk assessment is crucial for planning safe surgical care and for making decisions about proceeding with the surgery¹³.

Choice D reason:
Recognizing resources needed postoperatively is part of discharge planning and is essential for ensuring continuity of care. While it is an important consideration, it is not the immediate priority during the preoperative assessment².

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.
