Correct Answer: A

Rationale: As people age, the immune system becomes less efficient, a phenomenon known as immunosenescence. This decline in immune function includes reduced production of immune cells (such as T cells and B cells) and diminished responses to infections. During chemotherapy, which further suppresses the immune system, older clients are at a significantly higher risk of developing infections due to this age-related decrease in immune function. This is especially concerning because chemotherapy targets rapidly dividing cells, which include immune cells, making it even harder for the body to fight off infections.

Correct Answer: B

Rationale: For patients undergoing consolidation therapy for leukemia, severe fatigue is a common side effect of treatment due to factors such as anemia, decreased nutritional intake, and the body's response to chemotherapy. While exercise is beneficial, the patient's fatigue may limit their ability to engage in strenuous activity. Assisting the patient to sit in a chair during awake times is a practical way to encourage some physical activity while respecting their fatigue levels. This intervention helps prevent complications associated with immobility, such as muscle atrophy and venous stasis, without overwhelming the patient. It allows the patient to engage in light activity that is manageable and promotes recovery.

Correct Answer: C

Rationale: Patients with non-Hodgkin lymphoma (NHL) often experience a compromised immune system due to both the disease itself and the effects of treatments like chemotherapy and radiation, which cause myelosuppression (decreased production of blood cells, including white blood cells). This puts them at significant risk for infections. Avoiding crowded places is a crucial preventive measure, as it reduces the patient's exposure to pathogens that could lead to infections, which can be particularly severe due to their weakened immune system.

Correct Answer: B

Rationale: The best time to perform a testicular self-examination (TSE) is after a warm shower or bath. The heat from the water relaxes the scrotal skin, making it easier to feel any abnormalities, lumps, or changes in the testicles. This relaxation allows for a more thorough and accurate examination.

Correct Answer: B

Rationale: Radiation therapy can cause skin irritation, dryness, and sensitivity in the treated area. Wearing loose, soft clothing helps minimize friction and pressure on the skin, reducing irritation and promoting comfort. The skin in the treated area is often more sensitive and vulnerable to damage, so this intervention helps protect the skin while maintaining the client's comfort during the course of treatment.
