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 C
Explanation
Choice A reason:
Hay fever allergy, also known as allergic rhinitis, is primarily associated with the action of Immunoglobulin E (IgE) antibodies and not directly with T-cells. T-cells can contribute to the regulation of the immune response in allergies, but IgE is the main immunoglobulin involved in the typical symptoms of hay fever.
Choice B reason:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that involves the release of large amounts of histamine and other chemicals from mast cells and basophils, often triggered by IgE antibodies. While T-cells can play a role in the sensitization phase of allergy, anaphylaxis itself is not directly caused by T-cells.
Choice C reason:
Transplant rejection is a process in which T-cells play a central role. When a transplant recipient's immune system recognizes the donated organ as foreign, T-cells can mediate the rejection by attacking the transplanted tissue, leading to its failure.
Choice D reason:
Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. T-cells are involved in the adaptive immune response and can activate phagocytes, but they do not directly perform phagocytosis.
Correct Answer is ["B","C"]
Explanation
The correct answer is b. Minimize skin exposure to moisture and c. Use pillows to keep heels off the bed surface.
Choice A reason:
a. Massage over erythematous bony prominences: This is incorrect because massaging erythematous (reddened) areas can cause further tissue damage and exacerbate skin breakdown.
Choice B reason:
b. Minimize skin exposure to moisture: This is correct. Moisture can lead to skin maceration, increasing the risk of skin breakdown. Keeping the skin dry helps maintain its integrity.
Choice C reason:
c. Use pillows to keep heels off the bed surface: This is correct. Elevating the heels reduces pressure on them, preventing pressure ulcers.
Choice D reason:
d. Implement a turning schedule every 4 hours: This is incorrect. To prevent pressure injuries, turning should be done every 2 hours, not every 4 hours.
Choice E reason:
e. Keep the client’s skin dry with powder: This is incorrect. Powder can cause skin irritation and breakdown.
