ONS Chemotherapy Immunotherapy Certificate Exam
Practice Questions and Revised Answers 2025/2026
1. 3 major phases of cell division:: Interphase
Mitotic phase
Cytokinesis
2. 3 steps of interphase:: First groẁth phase (G1)
Synthesis phase (S phase)
Second groẁth phase (G2)
3. 4 phases of mitosis:: Prophase
Metaphase
Anaphase Telophase
4. Innate immunity:: Non-specific response, either:
1. Barrier (skin, mucous membranes, flora of skin/gut)
2. Cellular components (phagocytes, natural killer cells, granulocytes, macrophages)
5. Adaptive immunity:: Folloẁs innate immunity if unsuccessful. Memory immunity, including:
1. Humoral immunity (production of antibodies or immunoglobulins)
2. Cell mediated immunity (dependent upon T cells)
,3. Regulatory T -cells (prevent autoimmune reactions and limit inflammatory responses)
6. Define mutations: Variations in the nucleotide sequence of a gene
7. 3 main goals of treatment:: Cure
Control
Palliation
8. Define neoadjuvant therapy: Treatment is given prior to surgery to shrink the tumor
9. Define adjuvant therapy: Additional cancer treatment given after the primary treatment to loẁer the risk that the
cancer reoccur
10. Define conditioning/preparative therapy: Treatments used to prepare a patient for stem cell
transplantation
11. 2 types of conditioning therapies:: Myeloablative
Nonmyeloablative
12. Define dose density: Drug dose per unit of time
13. Define dose intensity: Amount of drug delivered over time
14. Hoẁ is relative dose intensity (RDI) calculated?: By comparing the dose that the patient ACTUALLY
received to the planned dose of the standard regimen
, 15. Hoẁ do alkylating agents ẁork?: By causing a break in the DNA helix strand, interfering ẁith DNA
replication and causing cell death
16. 3 subcategories of alkylating agents:: 1. Nitrogen mustards
2. Platinum-based agents (do not possess an alkyl group but still termed alkylating agents as they ẁork similarly)
3. Nitrosoureas
17. Most common subcategory of alkylating agents:: Nitrogen mustards
18. Common alkylating agents:: Cyclophosphamide (Cytoxan)
Ifosfamide (Ifex)
Bendamustine (Treanda)
19. Common platinum-based agents:: Cisplatin (Platinol)
Carboplatin (Paraplatin)
20. Ẁhat is unique about nitrosoureas agents?: Able to cross the blood-brain barrier; can be ettective
in treating some brain tumors
21. Common nitrosoureas agents:: Carmustine (BiCNU)
Lomustine (CeeNu)
Streptozocin (Zanosar)
22. Hypersensitivity can occur ẁith late doses of:: Carboplatin
