OCN Practice Test

Sample Questions and Answers

Question 1. A patient receiving chemotherapy develops a temperature of 38.5°C (101.3°F) and reports chills several days after treatment. What should the oncology nurse recognize as the highest priority?

A. Encourage the patient to rest at home until symptoms improve.

B. Suspect febrile neutropenia and notify the healthcare provider immediately.

C. Recommend over-the-counter pain medication only.

D. Schedule the patient for a routine clinic visit the following week.

Correct Answer: B. Suspect febrile neutropenia and notify the healthcare provider immediately.

Explanation:
Febrile neutropenia is a life-threatening oncologic emergency that commonly occurs after chemotherapy because of a reduced neutrophil count. Patients may have little ability to fight infection, making even a low-grade fever a medical emergency. Prompt assessment, laboratory evaluation, blood cultures, and initiation of broad-spectrum antibiotics are critical to reducing morbidity and mortality. Oncology nurses must recognize the signs of infection early and act quickly to ensure timely treatment. Febrile neutropenia management is a major topic on the OCN certification exam.

Question 2. An Oncology Certified Nurse is administering chemotherapy through a central venous catheter. During the infusion, the patient reports burning pain and swelling around the catheter insertion site. What should the nurse do first?

A. Continue the infusion at a slower rate.

B. Stop the chemotherapy infusion immediately and assess for possible extravasation.

C. Flush the catheter rapidly with saline.

D. Remove the central venous catheter immediately without further assessment.

Correct Answer: B. Stop the chemotherapy infusion immediately and assess for possible extravasation.

Explanation:
Pain, burning, swelling, or redness during chemotherapy administration may indicate extravasation, which occurs when a vesicant medication leaks into surrounding tissues. Immediate discontinuation of the infusion is essential to minimize tissue damage. The nurse should follow institutional protocols, assess the site, notify the healthcare provider, and initiate appropriate treatment. Early recognition and intervention help reduce the risk of severe tissue injury. Safe chemotherapy administration is a core competency assessed on the OCN certification examination.

Question 3. A patient receiving radiation therapy asks why fatigue has gradually worsened during treatment. Which response by the oncology nurse is most appropriate?

A. Fatigue is uncommon during radiation therapy.

B. Fatigue is a common side effect of radiation treatment and may increase as therapy continues.

C. Fatigue indicates that the treatment is no longer effective.

D. Fatigue always means the cancer has spread.

Correct Answer: B. Fatigue is a common side effect of radiation treatment and may increase as therapy continues.

Explanation:
Cancer-related fatigue is one of the most common side effects experienced during radiation therapy. It often develops gradually and may continue for several weeks after treatment ends. Factors contributing to fatigue include the body’s response to radiation, anemia, emotional stress, nutritional changes, and disrupted sleep. Oncology nurses play an important role in educating patients about energy conservation, nutrition, physical activity, and symptom management. Managing treatment-related side effects is a major focus of oncology nursing practice.

Question 4. An oncology patient reports severe bone pain that is not adequately controlled with the current medication regimen. What is the nurse’s priority action?

A. Tell the patient that pain is expected and should be tolerated.

B. Perform a comprehensive pain assessment and collaborate with the healthcare team to optimize pain management.

C. Stop all pain medications immediately.

D. Delay reporting the pain until the next scheduled appointment.

Correct Answer: B. Perform a comprehensive pain assessment and collaborate with the healthcare team to optimize pain management.

Explanation:
Effective pain management begins with a thorough assessment of pain intensity, location, quality, duration, aggravating factors, and the effectiveness of current treatments. Oncology nurses should use validated pain assessment tools, monitor treatment response, educate patients, and collaborate with providers to adjust medications or introduce additional therapies when needed. Uncontrolled cancer pain negatively affects quality of life, mobility, sleep, and emotional well-being. Pain assessment and management are essential competencies for OCN-certified nurses.

Question 5. A patient who recently completed cancer treatment asks about follow-up care and long-term health monitoring. What is the primary purpose of a survivorship care plan?

A. To eliminate the need for future medical visits.

B. To provide guidance for follow-up care, monitor for recurrence, manage long-term treatment effects, and promote healthy living.

C. To replace all communication with primary care providers.

D. To determine whether chemotherapy should be repeated every year.

Correct Answer: B. To provide guidance for follow-up care, monitor for recurrence, manage long-term treatment effects, and promote healthy living.

Explanation:
A survivorship care plan outlines a patient’s cancer treatment history, recommended follow-up schedule, surveillance for recurrence, management of long-term and late treatment effects, health promotion strategies, and coordination between oncology specialists and primary care providers. These plans help patients transition from active treatment to long-term survivorship while improving continuity of care and overall quality of life. Survivorship care is an increasingly important component of oncology nursing and is commonly assessed on the OCN certification exam.
