Oncology Certified Nurse (OCN®) — Questions and Answers
Question 1: CAR T-cell therapy can cause a potentially fatal immune complication characterized by high fever, hypotension, hypoxia, and multi-organ dysfunction. This is called:
- Cytokine release syndrome (CRS) (Correct answer)
- Tumor lysis syndrome
- Infusion-related hypersensitivity reaction
- Hemophagocytic lymphohistiocytosis (HLH) only
Correct answer: Cytokine release syndrome (CRS)
Cytokine release syndrome is a major toxicity of CAR T-cell therapy caused by massive cytokine secretion from activated CAR T-cells, leading to systemic inflammatory response and potential multi-organ failure.
Question 2: A patient is to begin treatment with Zometa for bone metastasis. Which laboratory tests or test is indicated prior to each dose of treatment?
- Serum creatinine/creatinine clearance (Correct answer)
- Liver function tests
- Carcinoembryonic antigen (CEA)

Question 14: According to a current theory of carcinogenesis, which of the following are not required to transform normal cells into malignant ones?
- A carcinogenic initiating agent
- Apoptosis (Correct answer)
- A promoter
- Permanent DNA mutation
Correct answer: Apoptosis
Explanation: <br> According to the three-stage theory of carcinogenesis, the malignant transformation of normal cells involves three distinct mechanisms. An initiator substance, which may be a chemical, physical, or biological carcinogen, damages DNA that affects a genetic change. <br><br> The damaged DNA may then undergo repair and no initiation occurs. However, if the damage is permanent (mutation), it may be subject to further modification of the cell physiology by a promoter substance that can lead to alterations in the cell's proliferative capacity or inhibit apoptosis (genetically programmed cell death). Some substances such as asbestos, tobacco smoke, or alcohol have both initiator and promoter properties.
