ATI Oncology Questions
1. An oncology nurse educator is providing health education to a patient who has been diagnosed with skin cancer. The patient’s wife has asked about the differences between normal cells and cancer cells. What characteristic of a cancer cell should the educator cite?
- A. Malignant cells contain more fibronectin than normal body cells.
- B. Malignant cells contain proteins called tumor-specific antigens.
- C. Chromosomes contained in cancer cells are more durable and stable than those of normal cells.
- D. The nuclei of cancer cells are unusually large, but regularly shaped.
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.
2. In an adult patient, which assessment finding is considered diagnostic of Hodgkin lymphoma?
- A. Schwann cells
- B. Reed-Sternberg cells
- C. Lewy bodies
- D. Loops of Henle
Correct answer: B
Rationale: The correct answer is B: Reed-Sternberg cells. In Hodgkin lymphoma, the presence of Reed-Sternberg cells in lymph node biopsy is diagnostic. These cells are large, atypical cells originating from B-lymphocytes. They are distinctive in appearance and are key to diagnosing Hodgkin lymphoma. Choices A, C, and D are incorrect because Schwann cells are related to nerve function, Lewy bodies are associated with Parkinson's disease, and Loops of Henle are structures in the kidney, none of which are specific to Hodgkin lymphoma.
3. A client hospitalized for chemotherapy has a hemoglobin of 6.1 mg/dL (61 mmol/L). The client is symptomatic but refuses blood transfusions. What medication does the nurse prepare to administer?
- A. Epoetin alfa.
- B. Filgrastim.
- C. Mesna.
- D. Dexrazoxane.
Correct answer: A
Rationale: Epoetin alfa stimulates the production of red blood cells, which is important for a client who refuses blood transfusions.
4. Nurse Joy is caring for a client with cancer who has been receiving cisplatin (Platinol-AQ). Which laboratory result requires an intervention by the nurse?
- A. White blood cell count of 6000 cells/microL
- B. Serum potassium level of 3.5 mEq/L
- C. Blood urea nitrogen (BUN) of 18 mg/dL
- D. Platelet count of 150,000 cells/microL
Correct answer: C
Rationale: The correct answer is C. A BUN level of 18 mg/dL is within the normal range; however, since cisplatin is nephrotoxic, it requires close monitoring. Elevated BUN levels can indicate impaired kidney function. Choices A, B, and D are within normal ranges and do not directly relate to cisplatin therapy or require immediate intervention.
5. The nurse is caring for a client who is at risk for tumor lysis syndrome. Which laboratory value requires the nurse to intervene?
- A. Decreased blood urea nitrogen (BUN)
- B. Increased serum calcium
- C. Increased creatinine level
- D. Increased blood glucose level
Correct answer: C
Rationale: Tumor lysis syndrome (TLS) is a potentially life-threatening condition that occurs when large numbers of cancer cells die rapidly, releasing their contents into the bloodstream. This can overwhelm the kidneys and lead to acute kidney injury. Creatinine is a waste product filtered out of the blood by the kidneys, and an elevated creatinine level is a sign of kidney dysfunction or damage. In TLS, increased creatinine levels indicate that the kidneys are struggling to filter out the excess waste products from cell breakdown, requiring immediate intervention to prevent further complications, such as acute renal failure.
