ATI Oncology Questions

Correct Answer: A

Rationale: Chemotherapy drugs are often vesicants, meaning they can cause severe tissue damage if they leak (extravasate) outside of the vein. When chemotherapy is administered through a peripheral IV line, it is crucial for the nurse to frequently assess the IV site for signs of complications such as redness, swelling, or pain, which could indicate extravasation. Checking for blood return ensures the IV catheter is still in the vein and functioning properly. Preventing tissue damage from chemotherapy extravasation is a top priority, and frequent monitoring helps ensure the infusion is proceeding safely.

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: An elevated white blood cell (WBC) count, also known as leukocytosis, is most commonly a response to infection. When the body detects an infection, the immune system responds by increasing the production of white blood cells to fight off the invading pathogens. The accompanying symptoms of fever and malaise are typical signs of infection, supporting the likelihood that this patient's health status is related to an infectious process rather than a more serious hematologic condition like lymphoma or leukemia.

Correct Answer: D

Rationale: The optimal time for performing a breast self-examination (BSE) is about one week after menstruation begins, as this is when the breasts are least likely to be swollen, tender, or affected by hormonal changes. Hormonal fluctuations during the menstrual cycle can cause temporary changes in breast tissue, such as swelling, lumpiness, or tenderness, which may make it more difficult to detect any unusual lumps or changes. Conducting the examination during this period ensures that the breasts are in their natural state, making it easier to notice any abnormalities.

Correct Answer: C

Rationale: Patients with myelodysplastic syndrome (MDS) have a dysfunctional bone marrow that leads to ineffective blood cell production, including white blood cells, which are crucial for fighting infections. As a result, they are at high risk for infections. Even a slight elevation in temperature, such as 37.5�C (99.5�F), could be an early sign of infection in an immunocompromised patient. Early detection and treatment of infections are critical in MDS patients, as infections can quickly become severe or life-threatening due to their compromised immune system.
