OCN Sample Questions and Answers

A 58-year-old patient with non-small cell lung cancer is scheduled for tumor genomic testing. Which statement is most appropriate for the nurse to include when obtaining informed consent for genomic testing?

A. “This test will always identify a targetable mutation.”
B. “Results may have implications for family members’ cancer risk.”
C. “You will receive results within 24 hours.”
D. “No insurance authorization is needed.”

Correct: B
Explanation: Genomic testing may reveal inherited or somatic alterations; some findings (e.g., pathogenic germline variants) have implications for family members who may be at increased cancer risk and could warrant genetic counseling. Nurses must explain possible familial implications, limitations of testing, turnaround variability, and potential insurance or privacy issues so patients can make informed choices.

A patient receiving pembrolizumab develops grade 2 diarrhea (4–6 stools/day above baseline). The best initial nursing action is to:

A. Continue immunotherapy and start loperamide.
B. Hold immunotherapy and notify the oncology provider for corticosteroid consideration.
C. Increase oral fluids only and observe.
D. Administer prophylactic antibiotics.

Correct: B
Explanation: Immune checkpoint inhibitor–related colitis can progress rapidly. Grade 2 diarrhea warrants holding immunotherapy and prompt provider evaluation; systemic corticosteroids are often indicated if moderate immune-related adverse events do not improve quickly. Symptomatic measures alone (e.g., loperamide) are insufficient without provider assessment to prevent complications.

A patient with newly diagnosed acute tumor lysis syndrome (TLS) shows hyperuricemia, hyperkalemia, and rising creatinine. The priority nursing intervention is:

A. Encourage oral potassium intake.
B. Initiate aggressive IV hydration and notify provider about uric-acid lowering therapy.
C. Restrict fluids to prevent pulmonary edema.
D. Start a high-potassium diet.

Correct: B
Explanation: TLS is a metabolic emergency caused by rapid tumor cell breakdown; aggressive IV hydration reduces uric acid crystallization and promotes renal perfusion. Prompt provider notification for uric-acid lowering therapy (allopurinol or rasburicase) and close monitoring of electrolytes/renal function are critical. Oral potassium is contraindicated in hyperkalemia.

Which finding best indicates successful central venous catheter (CVC) care after administration of vesicant chemotherapy?

A. No redness at insertion site and patient reports no pain on palpation.
B. Clear blood return and ability to flush catheter without resistance.
C. Visible bruising along catheter tunnel.
D. Lack of blood return but infusate flows easily.

Correct: B
Explanation: A functioning CVC should provide brisk blood return and flush without resistance; this confirms patency and appropriate intravascular catheter position. Absence of blood return with flow may indicate malposition, fibrin sheath, or catheter occlusion and requires assessment before further use to prevent extravasation or inadequate drug delivery.

A patient on oral targeted therapy reports missing doses frequently. Which nursing strategy is most likely to improve adherence?

A. Encourage the patient to take double doses when a dose is missed.
B. Review a simplified, written schedule aligned with daily routines and discuss side-effect management.
C. Advise stopping the drug when side effects occur.
D. Tell the patient to only take the medication on weekdays.

Correct: B
Explanation: Adherence to oral oncolytics improves with clear, practical strategies: simplified dosing schedules, written instructions tied to daily habits, education on managing common side effects, and discussion of the importance of consistent dosing. Doubling doses is unsafe; stopping without provider guidance risks treatment failure.

A patient receiving an infusion of anthracycline reports sudden pain and swelling at the IV site. The nurse suspects extravasation. Immediate best action:

A. Stop the infusion, aspirate residual drug from the catheter, and follow institution extravasation protocol.
B. Flush the line with saline to dilute the agent.
C. Leave the catheter in and continue infusion at slower rate.
D. Apply heat to the site and continue monitoring.

Correct: A
Explanation: For suspected vesicant extravasation, stop infusion immediately, do not flush the line, attempt to aspirate residual drug if catheter is in place, leave catheter in for potential antidote administration, elevate the limb, and follow the facility’s extravasation protocol (antidotes, cold/heat depending on agent). Heat/cold decisions depend on drug class; institutional protocol should guide care.

A 70-year-old patient with advanced cancer expresses desire to avoid resuscitation but is unclear about options. The nurse’s best response to support advance care planning is:

A. “I will document your wishes as ‘do not resuscitate’ without further discussion.”
B. “Can you tell me what concerns you most about resuscitation and what outcomes you would consider acceptable?”
C. “Family should decide; you don’t need to decide now.”
D. “Everyone should choose full code; it’s safer.”

Correct: B
Explanation: Effective advance care planning requires exploring the patient’s values, goals, and understanding of likely outcomes. Open-ended questions about concerns and acceptable outcomes help clarify preferences and lead to informed choices. Documentation should follow after a guided conversation; default or family decisions without patient input may not reflect patient wishes.

A patient undergoing external beam radiation to the chest develops a dry, nonproductive cough and low-grade fever one week after completing therapy. The nurse recognizes potential radiation pneumonitis. What is the most appropriate next step?

A. Reassure the patient it is normal and give an antitussive PRN.
B. Refer for clinical assessment — chest imaging and possible corticosteroid therapy.
C. Encourage strenuous exercise to clear the lungs.
D. Start broad-spectrum antibiotics immediately.

Correct: B
Explanation: Radiation pneumonitis can present weeks to months after thoracic radiation with cough, low-grade fever, and dyspnea. Prompt clinical assessment and imaging (e.g., chest x-ray or CT) are needed; corticosteroids are the mainstay for symptomatic moderate to severe cases. Empiric antibiotics are not first-line unless infection is suspected.

Which lab and clinical findings most strongly suggest febrile neutropenia requiring urgent evaluation?

A. Temperature 99.5°F and ANC 1,500/mm³.
B. Temperature 38.2°C (100.8°F) and ANC <500/mm³.
C. Temperature 37.8°C and stable WBC 6,000/mm³.
D. Low-grade fever with ANC 1,200/mm³ and no symptoms.

Correct: B
Explanation: Febrile neutropenia is defined as a single oral temperature ≥38.3°C (101°F) or ≥38.0°C (100.4°F) sustained, with an absolute neutrophil count (ANC) <500/mm³ (or expected to fall). This is an oncologic emergency requiring immediate evaluation, blood cultures, risk stratification, and often broad-spectrum IV antibiotics due to high infection risk.

A patient receiving CAR-T therapy develops high fevers and hypotension on day 3 post-infusion. The nurse is concerned about cytokine release syndrome (CRS). Which action is highest priority?

A. Apply cooling blankets only.
B. Rapidly notify the treating team and follow institutional CRS grading/treatment algorithm (e.g., tocilizumab, supportive care).
C. Delay intervention; fever is expected and will resolve spontaneously.
D. Start high-dose antibiotics without cultures.

Correct: B
Explanation: CRS can progress rapidly to life-threatening organ dysfunction. Early recognition and prompt activation of the treatment algorithm are essential; tocilizumab (anti-IL-6) is indicated for certain grades of CRS, along with supportive measures and ICU transfer if needed. Fever alone is insufficient reason to delay escalation; antibiotics may be needed but should follow assessment.

For a patient with metastatic breast cancer on bisphosphonate therapy, which dental recommendation should the oncology nurse emphasize?

A. Routine dental hygiene is unnecessary.
B. Complete necessary invasive dental procedures before initiating bisphosphonates when possible.
C. Bisphosphonates reduce the need for dental follow-up.
D. Start bisphosphonates immediately regardless of dental status.

Correct: B
Explanation: Antiresorptive agents (bisphosphonates, denosumab) carry a risk of medication-related osteonecrosis of the jaw (MRONJ). Best practice is to complete invasive dental procedures, optimize oral health, and counsel ongoing dental follow-up before starting therapy when feasible. Ongoing dental monitoring and prompt reporting of dental pain or nonhealing lesions are essential.

A patient with head and neck cancer complains of severe mucositis causing difficulty swallowing and weight loss. Which intervention is appropriate to include in the care plan?

A. Recommend only solid foods to build strength.
B. Implement pain control (topical/systemic), nutritional support (enteral if needed), and oral care protocols.
C. Stop all oral intake permanently.
D. Advise the patient to avoid analgesics to prevent constipation.

Correct: B
Explanation: Severe mucositis requires multimodal management: effective analgesia (topical anesthetics, systemic opioids when needed), nutritional interventions (diet modification, supplements, or enteral feeding if inadequate intake), and strict oral care to prevent infection. Stopping oral intake without alternative nutrition harms outcomes; constipation should be managed but is not a reason to withhold analgesia.

A patient scheduled for autologous stem cell transplant asks why cryopreservation of stem cells is necessary. The nurse’s best explanation:

A. Cryopreservation permanently changes cells to improve engraftment.
B. It allows collected peripheral blood stem cells to be stored until the patient is ready for high-dose therapy and reinfusion.
C. It makes stem cells resistant to chemotherapy.
D. It is only done for donor transplants.

Correct: B
Explanation: Cryopreservation stores harvested autologous stem cells at very low temperatures so they can be reinfused after the patient receives high-dose chemotherapy (which ablates bone marrow). This enables hematopoietic recovery. It does not alter cell resistance to chemotherapy; cryopreservation is used for both autologous and some allogeneic settings as appropriate.

Which symptom cluster most suggests superior vena cava (SVC) syndrome in a patient with thoracic malignancy?

A. Lower extremity edema and abdominal distention.
B. Facial and periorbital swelling, dyspnea, and prominent neck veins.
C. Jaundice and right upper quadrant pain.
D. Unilateral leg pain and calf swelling.

Correct: B
Explanation: SVC syndrome results from obstruction of venous return from the head, neck, and upper extremities, commonly from mediastinal tumors. Clinical features include facial/neck swelling, dyspnea, cough, and distended chest/neck veins. It can be life-threatening and requires rapid assessment, imaging, and often intervention (stenting, radiation, thrombolysis) depending on cause.

A patient with chronic cancer pain is prescribed a long-acting opioid patch. What teaching should the nurse emphasize?

A. Apply to different sites frequently to avoid tolerance.
B. Do not cut the patch; follow disposal instructions and monitor for signs of respiratory depression, especially when initiating therapy.
C. Immediately stop use if mild sedation occurs.
D. Store used patches for later use.

Correct: B
Explanation: Transdermal opioid patches should be used according to manufacturer instructions: do not cut patches (alters delivery), rotate application sites to prevent skin irritation, follow proper disposal to prevent accidental exposure, and monitor for respiratory depression particularly during initiation or dose increases. Mild sedation should prompt assessment but not necessarily abrupt cessation without provider guidance.

A 45-year-old woman with BRCA1-positive breast cancer asks about risk-reducing options for unaffected relatives. The nurse’s most accurate statement is:

A. “A positive BRCA1 result in you means all relatives will definitely develop cancer.”
B. “Relatives may consider genetic counseling and testing to clarify their personal cancer risk and preventive options.”
C. “Relatives don’t need to worry unless they have symptoms.”
D. “Testing is only useful for children, not adults.”

Correct: B
Explanation: A pathogenic BRCA1 variant in a patient indicates that biologic relatives may have an increased risk; genetic counseling is recommended so relatives can decide about testing and consider risk-reducing strategies (enhanced surveillance, chemoprevention, or prophylactic surgery). Counseling helps relatives understand inheritance patterns and options rather than assuming certainty of disease.

A patient receiving radiation and systemic therapy asks about fertility preservation. The nurse should:

A. Tell them fertility is never affected by cancer therapy.
B. Provide timely referral to fertility preservation services before gonadotoxic therapy, discuss options, and document informed decision-making.
C. Advise fertility preservation only after treatment is complete.
D. Discourage discussion to avoid anxiety.

Correct: B
Explanation: Many cancer therapies can impair fertility. Timely discussion and referral to reproductive specialists before starting gonadotoxic therapy enable consideration of preservation options (e.g., sperm/egg/embryo cryopreservation, ovarian suppression). Documenting the conversation and supporting informed decisions are nursing responsibilities; delaying discussion can eliminate options.

A patient with pancreatic cancer develops new onset confusion, anorexia, and constipation. Labs show calcium 13.2 mg/dL (normal 8.6–10.2). The nurse recognizes hypercalcemia of malignancy. The most appropriate immediate nursing action is:

A. Encourage oral calcium supplements.
B. Notify provider, begin IV hydration per protocol, and monitor cardiac rhythm and neurologic status.
C. Start oral phosphate without assessment.
D. Reassure the patient these findings are benign.

Correct: B
Explanation: Hypercalcemia of malignancy can cause neurocognitive changes and cardiac arrhythmias. Immediate management includes provider notification, IV hydration to increase renal calcium excretion, monitoring vitals and telemetry if indicated, and medications (bisphosphonates, calcitonin) as ordered. Supplements are contraindicated; timely intervention prevents deterioration.

A patient undergoing chemotherapy asks about complementary therapies for nausea. The nurse should:

A. Discourage all nonpharmacologic interventions.
B. Discuss evidence-based complementary options (acupuncture/acupressure, ginger, relaxation techniques) alongside prescribed antiemetics and evaluate for interactions.
C. Recommend herbal teas without review of interactions.
D. Advise stopping antiemetics if complementary strategies are used.

Correct: B
Explanation: Integrative approaches can complement antiemetic regimens; evidence supports interventions like acupuncture/acupressure, ginger, and behavioral therapies for some patients. Nurses should review safety, potential interactions with chemotherapy or anticoagulants, and integrate these with, not replace, prescribed antiemetics tailored to emetogenicity.

Which assessment finding in a patient receiving bevacizumab (anti-VEGF) requires immediate reporting?

A. Mild fatigue with normal blood pressure.
B. New severe headache and sudden visual changes.
C. Localized mild muscle soreness.
D. Occasional dry cough.

Correct: B
Explanation: Anti-VEGF agents increase the risk of serious adverse events including hypertension, arterial thromboembolism, bleeding, gastrointestinal perforation, and rare but serious posterior reversible encephalopathy syndrome (PRES) presenting with severe headache and visual changes. New severe neurologic symptoms warrant immediate evaluation.

A patient with metastatic disease expresses existential distress and asks about counseling. The nurse should:

A. Tell the patient counseling won’t help.
B. Offer referral to psychosocial oncology services, chaplaincy, and community resources, and validate feelings to normalize seeking support.
C. Recommend avoiding all discussions of feelings.
D. Suggest the patient handle emotions alone to remain strong.

Correct: B
Explanation: Psychosocial distress is common in oncology and impacts quality of life and treatment adherence. Nurses should validate concerns, offer integrated psychosocial oncology referrals (counseling, support groups), and connect patients with spiritual care or community resources. Early intervention improves coping and outcomes.

Which measure is most effective for preventing catheter-related bloodstream infections (CRBSI) in patients with implanted ports?

A. Routine dressing changes only when soiled.
B. Strict aseptic technique during access/maintenance, adherence to central line bundles, and education on site care.
C. Use of prophylactic systemic antibiotics daily.
D. Never accessing the port to reduce infection risk.

Correct: B
Explanation: Preventing CRBSI relies on evidence-based central line bundles: strict hand hygiene, maximal barrier precautions on insertion, chlorhexidine skin antisepsis, proper dressing and site care, and staff/patient education. Routine prophylactic systemic antibiotics are not recommended due to resistance; avoiding necessary access is not practical for treatment.

A patient with advanced cancer is admitted with sudden unilateral weakness and slurred speech. What immediate nursing action is indicated?

A. Schedule a CT scan within 24 hours.
B. Rapidly assess using stroke scale (e.g., NIHSS), call stroke team/oncology provider, and prepare for urgent imaging and treatment per stroke protocol.
C. Give oral aspirin and observe overnight.
D. Assume symptoms are due to anxiety.

Correct: B
Explanation: New focal neurologic deficits indicate possible stroke. Immediate assessment with a standardized scale, activation of the stroke response, and urgent neuroimaging are essential to determine eligibility for reperfusion therapies. Delays reduce treatment options and worsen outcomes; assuming anxiety or delaying imaging is unsafe.

A patient undergoing chemotherapy is at high risk for venous thromboembolism (VTE). Which nursing intervention supports VTE prevention?

A. Avoid mobility to prevent falls.
B. Assess individual VTE risk, encourage early ambulation, educate on signs/symptoms, and ensure prophylactic anticoagulation as ordered.
C. Recommend routine use of high-dose aspirin for all patients.
D. Discontinue prophylactic anticoagulation for convenience.

Correct: B
Explanation: Cancer increases VTE risk; prevention includes assessment of individual risk, early and frequent ambulation, use of mechanical prophylaxis when indicated, and administration of pharmacologic prophylaxis per risk and institutional protocols. Patient education on VTE signs is crucial. Routine aspirin is not standard for VTE prophylaxis in this context.

A 30-year-old woman receiving chemotherapy for Hodgkin lymphoma reports new amenorrhea. Which statement is accurate counseling by the nurse?

A. “Chemotherapy always causes permanent infertility.”
B. “Some chemotherapy regimens can cause temporary or permanent amenorrhea; refer to fertility preservation counseling and provide resources.”
C. “No further follow-up is needed; it will resolve on its own.”
D. “You must cease treatment immediately to preserve fertility.”

Correct: B
Explanation: Gonadotoxicity risk varies by agent, dose, and age; amenorrhea can be temporary or permanent. Early referral for fertility counseling and documentation of preferences are essential before initiating gonadotoxic therapy. Abruptly stopping therapy without discussion risks disease control; individualized counseling guides decisions.

A patient on combination chemo develops signs of anaphylaxis during infusion: hypotension, wheeze, urticaria. The nurse’s immediate action should be:

A. Stop the infusion, call for help, administer intramuscular epinephrine, and begin emergency resuscitation per protocol.
B. Slow the infusion and observe for 30 minutes.
C. Give oral antihistamine only.
D. Finish the infusion at a lower rate.

Correct: A
Explanation: Anaphylaxis is life-threatening; stop the offending infusion immediately, call for emergency assistance, administer intramuscular epinephrine promptly, secure airway/breathing/circulation, provide oxygen, IV fluids, and additional medications per ACLS/allergy protocols. Delaying intervention greatly increases morbidity.

When teaching a patient about survivorship care after curative cancer treatment, which component is essential to include?

A. No follow-up is necessary after remission.
B. A written survivorship care plan summarizing treatment received, potential late effects, recommended surveillance, and resources for health maintenance.
C. Only oncology should manage all future health concerns.
D. Surveillance imaging should be done weekly.

Correct: B
Explanation: Survivorship care plans are recommended best practice: they document prior treatments, outline potential late/long-term effects, delineate follow-up schedules and responsible providers, and provide health promotion guidance. This empowers patients and coordinates care between oncology and primary care. Excessive imaging is not appropriate.

A patient expresses financial toxicity concerns about high out-of-pocket costs for therapy. The nurse should:

A. Tell the patient to stop treatment to save money.
B. Screen for financial distress, provide information about assistance programs, social work referral, and discuss cost-effective options when clinically appropriate.
C. Ignore the concern as nonclinical.
D. Advise the patient to take fewer doses to reduce costs.

Correct: B
Explanation: Financial toxicity affects adherence and outcomes. Nurses should screen for financial distress, provide resources (drug assistance programs, foundations, hospital financial counselors), refer to social work and pharmacy for cost mitigation, and collaborate with the team to consider clinically appropriate, cost-sensitive alternatives. Reducing doses without provider guidance is unsafe.

A patient’s family requests withholding bad news from the patient. The nurse’s best action is to:

A. Respect the family’s wish and withhold information.
B. Advocate for the patient’s right to be informed, assess the patient’s desire for information, and involve ethics or legal resources if conflicts persist.
C. Tell the family you will decide what to disclose.
D. Ignore the family and disclose everything without assessing the patient’s preferences.

Correct: B
Explanation: Respect for patient autonomy requires assessing the patient’s preferences for information. Families may request nondisclosure for cultural reasons, but nurses must determine what the patient wants and advocate accordingly. If conflict arises, involve ethics, palliative care, or legal resources to resolve differences while prioritizing the patient’s rights.

Which documentation practice most enhances safe chemotherapy administration and continuity of care?

A. Vague notes such as “chemo tolerated.”
B. Detailed documentation of drug name/dose/route/time, premedication, patient response, infusion site checks, and patient education given.
C. Documenting only in the physician’s notes.
D. Omitting adverse reaction details to avoid legal issues.

Correct: B
Explanation: Comprehensive documentation is essential for safety and legal/clinical continuity: record exact drug names (generic), doses, routes, lot numbers/expiration when required, time, premedications, IV site assessments, adverse events and interventions, and patient education. Accurate records enable safe subsequent care, pharmacovigilance, and quality improvement.

A patient receiving CAR-T cell therapy becomes acutely confused, has difficulty speaking, and develops a severe headache. What is the nurse’s priority concern?

A. Opioid overdose
B. Immune effector cell–associated neurotoxicity syndrome (ICANS)
C. Acute stroke unrelated to treatment
D. Anxiety reaction

Correct Answer: B

Explanation:
CAR-T therapy can cause ICANS, a potentially life-threatening neurologic toxicity characterized by confusion, aphasia, headache, seizures, and decreased level of consciousness. Early recognition and immediate escalation per institutional protocol are critical. Delay can lead to cerebral edema and severe neurologic injury. Nurses play a key role in early neurologic assessment and rapid response.

A patient with acute leukemia develops sudden shortness of breath, fever, hypotension, and hypoxia shortly after starting induction chemotherapy. What complication is the nurse most concerned about?

A. Pulmonary embolism
B. Acute respiratory distress syndrome (ARDS)
C. Cytokine release syndrome
D. Anxiety attack

Correct Answer: B

Explanation:
Induction chemotherapy can trigger ARDS due to inflammatory injury, infection, or leukostasis. Rapid onset hypoxia, fever, and hypotension require immediate escalation, oxygenation support, and ICU-level care. Early recognition by nurses is critical to prevent respiratory failure and death.

A 56-year-old patient with diffuse large B-cell lymphoma is admitted for the first cycle of combination chemotherapy. Six hours after infusion begins, the patient develops nausea, flank pain, and dark urine. Labs show rising potassium and uric acid.

What is the nurse’s priority action?

A. Administer antiemetics and reassess
B. Increase oral fluids
C. Notify the provider and initiate tumor lysis syndrome protocol
D. Document findings and continue monitoring

Correct Answer: C

Explanation:
This scenario indicates early tumor lysis syndrome (TLS). High-grade lymphomas are high-risk, especially during first treatment. Rising potassium and uric acid signal imminent cardiac and renal complications. Immediate provider notification and initiation of TLS management (IV hydration, cardiac monitoring, uric-acid–lowering therapy) are lifesaving. Delay can result in fatal arrhythmias or acute kidney failure.

A neutropenic patient (ANC 320/mm³) calls the oncology triage line reporting chills and an oral temperature of 100.5°F (38.1°C).

What should the nurse instruct the patient to do immediately?

A. Take acetaminophen and recheck temperature
B. Increase oral fluids
C. Come to the emergency department now
D. Schedule a clinic visit tomorrow

Correct Answer: C

Explanation:
This is febrile neutropenia, an oncologic emergency. Any temperature ≥100.4°F with severe neutropenia requires immediate evaluation, cultures, and empiric IV antibiotics. Delaying care dramatically increases mortality due to rapid progression to sepsis. Telephone reassurance or antipyretics alone is unsafe.
