ATI Oncology Questions

Correct Answer: B

Rationale: Before any invasive procedure, such as placing a catheter to deliver chemotherapy beads into a liver tumor, it is essential to ensure that informed consent has been obtained from the client. This is a legal and ethical requirement that ensures the client understands the procedure, its risks, benefits, and alternatives. Ensuring that the signed consent is on the chart is the most important action the nurse can take before the procedure, as the procedure cannot legally proceed without it.

Correct Answer: A

Rationale: Fatigue and weakness are common side effects of radiation therapy, often due to the body's response to radiation damage and the energy required to repair both cancerous and healthy cells affected by the treatment. Reassuring the patient that these symptoms are expected while also emphasizing ongoing monitoring (through lab and x-ray studies) provides both comfort and a sense of proactive care. It ensures the patient that their symptoms are being addressed in a safe and medically appropriate way.

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.

Correct Answer: B

Rationale: Malignant (cancer) cells often express tumor-specific antigens (TSAs), which are proteins or markers on the surface of cancer cells that are not found on normal cells. These antigens are produced due to genetic mutations in cancer cells and can sometimes be used to help the immune system recognize and attack cancerous cells. Tumor-specific antigens play a key role in cancer diagnosis, monitoring, and targeted therapies.
