ATI Oncology Questions

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: D

Rationale: While chemotherapy does affect normal, healthy cells-particularly those that divide rapidly-it is not "more likely" to kill normal cells compared to cancer cells. Chemotherapy targets rapidly dividing cells, which includes both cancer cells and some normal cells (like those in hair follicles, the gastrointestinal tract, and bone marrow). However, its primary goal is to kill cancer cells, and its effects on normal cells are a side effect, not the main function. Therefore, the statement that chemotherapy is "more likely" to kill normal cells is inaccurate and indicates a need for further teaching.

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: 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: C

Rationale: Superior vena cava syndrome (SVCS) occurs when the superior vena cava, the large vein that carries blood from the upper body to the heart, becomes compressed or obstructed, often by a tumor or enlarged lymph nodes, typically in cancers like lung cancer or lymphoma. The obstruction leads to increased venous pressure and reduced blood flow, resulting in swelling and edema in areas drained by the superior vena cava. Periorbital edema (swelling around the eyes) is one of the earliest signs of SVCS. This occurs because the impaired venous return causes fluid to accumulate in the soft tissues of the face, especially around the eyes. As the condition progresses, facial swelling can worsen, and other symptoms develop.
