Chemotherapy Practice Exam Questions and Answers
Chemotherapy is a cornerstone of cancer treatment, targeting rapidly dividing cells. To excel in chemotherapy exams, it’s essential to grasp the mechanisms, classifications, and side effects of these drugs. Here’s a quick guide to help you prepare effectively.
Understand the Basics
- Cell Cycle Phases: Know which drugs target specific phases (e.g., S phase: Methotrexate, G2-M phase: Bleomycin).
- Cancer Biology: Learn how chemotherapy exploits the differences between cancerous and normal cells.
Major Drug Classes
- Alkylating Agents: Cyclophosphamide, Cisplatin
- Antimetabolites: Methotrexate, 5-Fluorouracil
- Natural Products: Vincristine, Paclitaxel, Doxorubicin
- Targeted Therapy: Imatinib, Trastuzumab
- Hormonal Agents: Tamoxifen, Anastrozole
Mechanisms of Action
- Focus on how drugs interfere with DNA replication, mitosis, or specific signaling pathways (e.g., tyrosine kinase inhibitors).
Adverse Effects
- Common Toxicities: Nausea, myelosuppression, alopecia.
- Organ-Specific Effects: Nephrotoxicity (Cisplatin), cardiotoxicity (Doxorubicin).
Clinical Applications
- Identify drugs used for specific cancers (e.g., Tamoxifen for breast cancer, Cisplatin for testicular cancer).
Practice Questions
- Questions often test mechanisms, adverse effects, and clinical scenarios.
- Example:
“Which chemotherapeutic agent causes dose-limiting cardiotoxicity?”
(Answer: Doxorubicin)
Study Tips
- Use mnemonics for side effects (e.g., Cisplatin → C for ears → ototoxicity).
- Practice with reliable question banks, such as those on examsage.com.
