ONCC Radiation Oncology Certified Nurse Examination Practice Test
Radiation oncology nursing focuses on safe, supportive care for patients receiving therapeutic radiation. The practice questions sample patient teaching and symptom assessment across external-beam treatment, including skin care, fatigue, swallowing changes, cough, and nutrition. They also touch on treatment scheduling and concerns about medications or new symptoms during a course of therapy.
Exam overview
About the ONCC Radiation Oncology Certified Nurse Examination Exam
Radiation-related nursing decisions include distinguishing expected local effects from symptoms that need prompt assessment or escalation. Patients may need guidance about skin irritation, sore throat, hoarseness, esophageal discomfort, reduced appetite, and when to report respiratory changes. Care also involves explaining that external-beam treatment does not make the patient radioactive, while avoiding assumptions that apply to other radiation modalities. Practical work includes supporting attendance when transportation is a barrier, responding to a missed session through the treatment team, and reinforcing that prescribed medicines should not be stopped without clinical guidance. New arm swelling after lymph-node surgery calls for assessment and timely follow-up rather than a casual reassurance. These topics connect symptom triage, treatment education, adherence support, and coordination with radiation oncology clinicians.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A patient receiving radiation to the breast asks whether deodorant can be used in the treatment area. What is the best nursing response?
Show answer
Correct answer: CSkin-care recommendations can vary with the treatment area and the patient’s skin condition. The patient should follow the radiation team’s instructions about products and report skin changes rather than applying products that might irritate the area or interfere with care.
A patient scheduled for external-beam radiation asks whether they will be radioactive after treatment. What is the best response?
Show answer
Correct answer: BExternal-beam radiation delivers radiation from a machine and does not leave the patient radioactive. This differs from some forms of internal radiation therapy, for which temporary precautions may be needed.
A patient receiving radiation to the chest develops a persistent dry cough and increasing shortness of breath. What should the nurse do first?
Show answer
Correct answer: ANew or worsening cough and dyspnea during or after chest radiation require assessment because they may reflect treatment effects or another clinically important condition. The nurse should promptly communicate the symptoms rather than dismissing them.
A patient is receiving radiation to the upper abdomen and has a reduced appetite. Which nutritional approach is generally appropriate to discuss with the care team?
Show answer
Correct answer: ASmall, frequent meals may be easier to tolerate when appetite is reduced. Persistent low intake or weight loss should be reported so the team can assess nutritional needs and offer individualized support.
A patient receiving radiation to the head and neck reports a new sore throat and hoarseness. What is the best nursing action?
Show answer
Correct answer: AThroat symptoms can affect swallowing, hydration, and nutrition and should be assessed. The nurse should clarify severity and functional impact and communicate concerning or worsening symptoms so the team can determine appropriate care.
A patient receiving radiation to the chest has difficulty swallowing pills because of treatment-related esophageal irritation. What should the nurse recommend?
Show answer
Correct answer: BNot all pills can be crushed or altered safely, and stopping prescribed medications without advice may be harmful. The prescriber or pharmacist can review the medication list and identify suitable formulations or routes.
A patient receiving radiation asks what to do after accidentally missing a scheduled treatment session because of transportation problems. What is the best advice?
Show answer
Correct answer: ATreatment timing and any schedule changes should be coordinated by the radiation oncology team. Patients should not attempt to compensate with extra doses or independently change treatment locations.
How to use this practice test
Access is free. The published bank contains 50 questions; each practice session presents up to 20 questions selected at random and shows results afterward. Use a session to identify gaps in radiation-treatment teaching, symptom recognition, and escalation decisions, then revisit any missed concepts.
Preparation tips
- Compare common localized radiation effects, such as skin irritation or swallowing discomfort, with new respiratory symptoms that warrant prompt assessment.
- Practice explaining external-beam radiation precautions accurately, and distinguish them from instructions that may apply to internal radiation treatments.
- Review how to respond when treatment attendance is disrupted: identify the barrier and involve the radiation oncology team rather than advising patients to change the schedule independently.
- For medication questions, reinforce adherence to prescribed therapy and direct concerns about anticoagulants or other drugs to the prescribing clinician and treatment team.
- Connect nutrition and swallowing concerns with practical assessment: note reduced intake, difficulty taking pills, or worsening throat symptoms and coordinate appropriate follow-up.
