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 D
Explanation
Choice A reason:
While examining the client for areas of skin breakdown is an important part of ongoing care, especially for clients with spinal cord injuries who are at increased risk for pressure ulcers, it is not the first action to take when autonomic dysreflexia is suspected. Skin breakdown is not an immediate life-threatening issue compared to the potential complications of autonomic dysreflexia.
Choice B reason:
Checking the client's bladder for distention is a critical step in the management of autonomic dysreflexia, as an overfull bladder is a common trigger for this condition. However, the very first action should be to place the client in a sitting position to lower blood pressure, which can be dangerously high during an episode of autonomic dysreflexia.
Choice C reason:
Checking for fecal impaction is another important intervention for managing autonomic dysreflexia, as an impacted bowel can also trigger an episode. However, similar to checking for bladder distention, this is not the first action to take. Immediate measures to lower blood pressure are prioritized for the safety of the client.
Choice D reason:
Placing the client in a sitting position, or elevating the head of the bed to at least 45 degrees, is the first and most critical action when autonomic dysreflexia is suspected. This position helps to lower blood pressure by promoting venous return to the heart and can prevent complications such as stroke from the sudden hypertension associated with autonomic dysreflexia.
Correct Answer is B
Explanation
Choice A reason:
In primary hypothyroidism, the thyroid gland is underactive and does not produce sufficient thyroid hormones, including Free T4. Therefore, we would not expect an elevation of Free T4 in primary hypothyroidism; instead, its levels would typically be low or normal.
Choice B reason:
Thyroid stimulating hormone (TSH) levels are elevated in primary hypothyroidism because the pituitary gland releases more TSH in an attempt to stimulate the thyroid gland to produce more thyroid hormones. This is a compensatory response to the low levels of circulating thyroid hormones, particularly thyroxine (T4).
Choice C reason:
Serum T3 levels may be low or normal in primary hypothyroidism. T3 is the active form of thyroid hormone and is usually converted from T4. If T4 levels are low, T3 levels may also be affected; however, T3 levels are not the primary diagnostic marker for hypothyroidism and do not typically show elevation in this condition.
Choice D reason:
Serum T4 levels are typically low in primary hypothyroidism because the thyroid gland is not producing enough of this hormone. An elevation of serum T4 would not be expected unless the patient is receiving treatment for hypothyroidism.
