A nurse is planning to teach a client who is scheduled for an intravenous pyelogram (IVP). Which of the following statements should the nurse include in the teaching?

Choice A reason:
A personal trainer working with a client who has HIV is at low risk for contracting the virus. HIV is not transmitted through casual contact, sweat, or saliva. The risk would increase only if there were exposure to blood or other body fluids through an open wound or mucous membrane.

Choice B reason:
An occupational therapist working with a client who has HIV also has a low risk of contracting the virus. Similar to a personal trainer, unless there is direct exposure to blood or body fluids, the transmission risk is minimal.

Choice C reason:
A phlebotomist who collects blood from clients who have HIV is at the greatest risk among the listed individuals. Phlebotomists are healthcare professionals who are frequently exposed to blood, which is a bodily fluid that can transmit HIV if proper precautions are not taken.

Choice D reason:
A nurse who collects urine samples is at a lower risk compared to a phlebotomist. HIV is not typically transmitted through urine unless it contains blood. However, the risk is still present if there is exposure to blood-contaminated urine through cuts or mucous membranes.

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.
