Oncology Nursing Practice: Scope, Ethics, Trials, and Safety
What the exam tests
Scope and standards of oncology nursing, the interdisciplinary team, evidence-based practice, clinical trial phases, informed consent, confidentiality and advocacy, safe handling of hazardous drugs, and central vascular access device management.
Clinical trials
- Phase I: safety, dose finding, maximum tolerated dose - not effectiveness.
- Phase II: does it work in a specific cancer type?
- Phase III: is it better than the current standard?
- Phase IV: post-marketing surveillance and long-term or late effects.
Safe handling
USP <800> expectations: closed system transfer devices, double gloves, gown, eye and face protection, spill kits, and precautions with body fluids and excreta for at least 48 hours after chemotherapy administration. Pregnant or breastfeeding staff should be reassigned away from hazardous drug handling. Oral chemotherapy is hazardous too - never crush or open capsules without protection.
Vascular access
Confirm patency and blood return before giving a vesicant. Stop the infusion immediately for pain, resistance, or swelling and follow the extravasation protocol; do not flush.
Traps
- "The nurse obtains informed consent." Not correct - the prescriber obtains it; the nurse witnesses the signature and verifies understanding.
- Describing phase I as testing effectiveness.
- Assuming oral agents are safe to handle bare-handed.
- Forgetting that documentation and timely escalation of abnormal findings are core professional standards.
Rule of thumb
For trial phases think Safe, Effective, Better, Long-term: I safety, II effect, III better than standard, IV long-term effects.
