A nurse is assessing a client who reports a nevus that has increased in size and an irregularly shaped lesion that varies in color. These findings are consistent with which of the following medical diagnoses?
Squamous cell carcinoma
Malignant melanoma
Kaposi's sarcoma
Basal cell carcinoma
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A reason:
While autoimmune disorders are associated with type 1 diabetes, where the immune system attacks the pancreas, they are not typically a direct risk factor for type 2 diabetes. Type 2 diabetes is more closely related to lifestyle factors and insulin resistance.
Choice B reason:
A 40-year-old client with hypoglycemia may be at risk for developing type 2 diabetes. Hypoglycemia can be a sign of pre-diabetes or insulin resistance, where the body's response to insulin is not as effective, leading to fluctuations in blood sugar levels. As individuals age, their risk for type 2 diabetes increases, particularly if they have other risk factors such as a sedentary lifestyle, overweight, or a family history of diabetes.
Choice C reason:
Lack of sleep can contribute to the development of type 2 diabetes by affecting the body's ability to regulate glucose and by increasing insulin resistance. However, without additional risk factors, it is not as strong a predictor of type 2 diabetes as the presence of hypoglycemia or other metabolic conditions.
Choice D reason:
Having never given birth is not a recognized risk factor for type 2 diabetes. While gestational diabetes is a risk factor for developing type 2 diabetes later in life, the absence of pregnancy does not increase the risk.
Correct Answer is B
Explanation
Choice A reason:
This statement is misleading. While many herbal therapies are generally considered safe, they can have side effects and interact with other medications. It is important to consult with a healthcare provider before starting any new herbal therapy.
Choice B reason:
This statement is accurate. Many herbal products have not been subjected to rigorous long-term testing that is required for conventional medications. Therefore, their long-term safety and efficacy profiles are not always well-established.
Choice C reason:
This statement is incorrect. Some herbal therapies have been found to be beneficial in reducing menopausal discomfort, such as hot flashes and night sweats. However, their effectiveness can vary from person to person.
Choice D reason:
This statement is not advisable without further assessment. While some herbal therapies may help with menopausal symptoms, it is important for the client to discuss with a healthcare provider to consider personal health history, potential side effects, and interactions with other medications.
