Which instruction is most important for the nurse to give a client who is receiving radiation therapy for lung cancer when teaching about skin care?

Ice packs may be applied to the site for 30 minutes every hour for comfort

Wear loose soft clothing over the treated area

Do not share bathrooms or toilets with others for 48 hours after treatment

Incorporate rest periods within the day

Answer and Explanation

The Correct Answer is B

A. Applying ice packs to the radiated area is not typically recommended, as it can cause additional skin irritation or damage. Skin care after radiation usually focuses on keeping the skin moisturized and protected.
B. Wear loose soft clothing over the treated area is the most important instruction because radiation therapy can cause skin irritation and sensitivity. Wearing loose, soft clothing helps to avoid further friction or irritation on the sensitive skin in the treated area.
C. Avoiding sharing bathrooms or toilets with others for 48 hours after treatment is not a required precaution for external radiation therapy, as there is no significant risk of radiation exposure to others through contact with shared bathroom facilities. This is more applicable to certain types of radioactive implants or internal radiation therapies.
D. While rest is important during cancer treatment, this instruction is more general and not as specific to skin care management during radiation therapy. The primary focus for skin care would be preventing irritation and damage to the skin in the radiated area.

A. Decreased surface antigens B. Increased CD4 cells C. Decreased killer T cells D. Increased viral burden

Correct Answer is B

Explanation

A. Decreased surface antigens are more relevant to hepatitis B infection than to monitoring HIV treatment effectiveness.
B. Increased CD4 cells indicate an effective response to antiretroviral therapy, as CD4 cells are a key component of the immune system that HIV targets and destroys. Effective therapy allows CD4 counts to recover.
C. Decreased killer T cells (CD8 cells) would not be a desired effect; these cells help control viral infections, including HIV.
D. Increased viral burden (or viral load) suggests worsening of the infection, not improvement. Effective therapy should decrease the viral load.
