ONS/ONCC Chemotherapy Immunotherapy Certificate (OCC) — Questions and Answers
Question 1: An oncology patient asks the nurse about expanded access (compassionate use) for an unapproved drug. What is the nurse's BEST response?
- Expanded access may allow seriously ill patients to access investigational drugs outside of a clinical trial; the provider can apply through the FDA (Correct answer)
- Expanded access is not monitored by the FDA and carries no regulatory oversight
- Compassionate use is the same as participation in a Phase I trial
- Expanded access is only available after a patient fails all FDA-approved treatments and clinical trials
Correct answer: Expanded access may allow seriously ill patients to access investigational drugs outside of a clinical trial; the provider can apply through the FDA
The FDA's expanded access program allows seriously ill patients who lack alternatives to access investigational drugs outside of clinical trials, with the treating physician submitting a request to the FDA.
Question 2: A patient's implanted port is not flushing easily and has resistance. The nurse suspects an occlusion. Which intervention should be attempted FIRST?
- Reposition the patient (raise arm, cough, or change position) and reattempt (Correct answer)
- Force flush with 20 mL normal saline
- Administer alteplase (tPA) immediately
- Remove and replace the Huber needle
Correct answer: Reposition the patient (raise arm, cough, or change position) and reattempt
Positional occlusion caused by catheter kinking can be resolved by patient repositioning before escalating to pharmacologic interventions.
Question 3: Which dressing change frequency is recommended for a tunneled central venous catheter exit site according to current evidence-based guidelines?
- Only when visibly soiled or loose
- Every 48 hours with antimicrobial gauze
- Every 24 hours with gauze dressing
- Every 7 days with transparent semi-permeable membrane dressing (unless soiled) (Correct answer)
Correct answer: Every 7 days with transparent semi-permeable membrane dressing (unless soiled)
Current INS and CDC guidelines recommend transparent dressing changes every 7 days for tunneled CVC exit sites unless the dressing becomes wet, soiled, or loose.
Question 4: A nurse is providing spiritual care to a Muslim patient with terminal cancer who is declining end-of-life medications due to religious concerns about sedation. What is the BEST approach?
- Override the patient's decision because comfort is the primary goal of hospice
- Respect the patient's religious autonomy, involve a chaplain, and explore non-sedating symptom management alternatives (Correct answer)
- Consult psychiatry for assessment of decision-making capacity
- Document the refusal and take no further action
Correct answer: Respect the patient's religious autonomy, involve a chaplain, and explore non-sedating symptom management alternatives
Respecting patient autonomy and religious beliefs requires an interdisciplinary approach including chaplaincy, while exploring non-sedating alternatives that align with the patient's values.
Question 5: Which intervention is the MOST critical in preventing tumor lysis syndrome in high-risk patients?
- Placing the patient on continuous telemetry only
- Aggressive IV hydration and allopurinol or rasburicase administration before chemotherapy (Correct answer)
- Administering calcium gluconate prophylactically
- Restricting dietary potassium
Correct answer: Aggressive IV hydration and allopurinol or rasburicase administration before chemotherapy
Aggressive IV hydration dilutes metabolites and promotes renal excretion, while allopurinol or rasburicase prevents uric acid accumulation before chemotherapy initiation.
Question 6: A nurse notes an unexpected serious adverse event in a patient on a clinical trial. What is the MOST important immediate action?
- Report the adverse event to the IRB within 10 business days
- Withdraw the patient from the study before reporting
- Report directly to the FDA without involving the PI
- Document the event in the chart, report to the principal investigator immediately, and complete the adverse event report per protocol (Correct answer)
Correct answer: Document the event in the chart, report to the principal investigator immediately, and complete the adverse event report per protocol
Serious adverse events must be documented, immediately reported to the PI, and captured in the adverse event reporting system per the protocol's safety monitoring plan.
Question 7: A nurse researcher is reviewing a meta-analysis on antiemetic efficacy. What does this study design involve?
- An expert panel review of case reports
- A single large RCT with pre-specified interim analyses
- Prospective observation of a patient cohort without an intervention
- Statistical pooling of results from multiple independent studies on the same question (Correct answer)
Correct answer: Statistical pooling of results from multiple independent studies on the same question
A meta-analysis statistically combines results from multiple independent studies to increase statistical power and provide a more precise estimate of treatment effect.
Question 8: A patient with bone metastases and moderate pain (5/10) is on scheduled long-acting opioids. They ask what the breakthrough dose should be. What is the standard calculation?
- The breakthrough dose equals the full daily opioid dose divided by 24
- The breakthrough dose is typically 10-15% of the total daily opioid dose, given every 1-4 hours as needed (Correct answer)
- The breakthrough dose should equal the long-acting dose given twice daily
- No breakthrough doses are needed if long-acting opioids are optimized
Correct answer: The breakthrough dose is typically 10-15% of the total daily opioid dose, given every 1-4 hours as needed
Standard oncology pain management guidelines recommend breakthrough doses of 10-15% of the total daily opioid dose, available every 1-4 hours for episodic or breakthrough pain.
Question 9: A patient receiving chemotherapy reports moderate-to-severe cancer-related fatigue. Which assessment finding would indicate a potentially treatable contributing cause?
- Hemoglobin of 7.5 g/dL with symptoms of dyspnea on exertion (Correct answer)
- ANC of 2,000/mm³ at end of cycle
- Weight loss of 2 lbs over 3 weeks
- Mild insomnia reported by the patient
Correct answer: Hemoglobin of 7.5 g/dL with symptoms of dyspnea on exertion
Anemia (Hgb 7.5 g/dL) with symptomatic dyspnea is a directly treatable cause of cancer-related fatigue, warranting evaluation for RBC transfusion or erythropoiesis-stimulating agents.
Question 10: A patient receiving high-dose cyclophosphamide reports severe bladder pain, urinary frequency, and grossly bloody urine. What complication has occurred?
- Bladder cancer as a late effect
- Renal failure from drug nephrotoxicity
- Hemorrhagic cystitis from acrolein metabolite accumulation (Correct answer)
- Urinary tract infection
Correct answer: Hemorrhagic cystitis from acrolein metabolite accumulation
Hemorrhagic cystitis is caused by acrolein, a toxic metabolite of cyclophosphamide that accumulates in the bladder, causing mucosal damage and bleeding.
Question 11: A nurse is asked to participate in a clinical trial that requires randomizing patients between a proven chemotherapy regimen and an experimental arm. The ethical requirement for this is called:
- Clinical equipoise (Correct answer)
- Therapeutic privilege
- Beneficent paternalism
- Informed assent
Correct answer: Clinical equipoise
Clinical equipoise requires genuine uncertainty about which treatment arm is superior before randomizing patients in a trial.
Question 12: Which action is required before administering intrathecal chemotherapy to comply with safe handling standards?
- Sequester intrathecal preparations separately and label clearly; administer in a dedicated procedure separate from IV chemotherapy (Correct answer)
- Verify patency with a 10 mL normal saline flush into the intrathecal space
- Confirm the drug was dispensed in a minibag rather than a syringe to distinguish it from IV medications
- Administer it concurrently with IV chemotherapy to reduce the number of patient visits
Correct answer: Sequester intrathecal preparations separately and label clearly; administer in a dedicated procedure separate from IV chemotherapy
Intrathecal chemotherapy must be prepared in a syringe, clearly labeled, sequestered, and administered in a dedicated procedure completely separate from any IV chemotherapy to prevent fatal route errors.
Question 13: After extravasation of doxorubicin, what is the recommended topical treatment to minimize tissue damage?
- Apply hyaluronidase topically to the site
- Inject sodium thiosulfate subcutaneously around the site
- Apply cold compress and administer dexrazoxane IV per protocol (Correct answer)
- Apply warm compress for 20 minutes four times daily
Correct answer: Apply cold compress and administer dexrazoxane IV per protocol
Cold compresses limit drug spread, and dexrazoxane is the FDA-approved antidote for anthracycline extravasation that prevents progressive tissue necrosis.
Question 14: Which patient population is at HIGHEST risk for developing oral mucositis during chemotherapy?
- Patients receiving hormonal therapy for breast cancer
- Patients receiving immunotherapy checkpoint inhibitors
- Patients receiving oral targeted therapies only
- Patients receiving high-dose methotrexate, 5-FU, or those undergoing bone marrow transplant conditioning (Correct answer)
Correct answer: Patients receiving high-dose methotrexate, 5-FU, or those undergoing bone marrow transplant conditioning
High-dose antimetabolites (methotrexate, 5-FU) and myeloablative conditioning regimens for bone marrow transplant carry the highest risk of severe oral mucositis.
Question 15: According to ASCO/ONS chemotherapy administration standards, a two-nurse independent double-check is required before giving which type of drug?
- Antifungal prophylaxis given concurrently with chemotherapy
- High-alert chemotherapy agents, particularly those with a narrow therapeutic index (Correct answer)
- All oral medications dispensed in the oncology clinic
- Any antiemetic given with chemotherapy
Correct answer: High-alert chemotherapy agents, particularly those with a narrow therapeutic index
High-alert chemotherapy drugs with narrow therapeutic indices require an independent double-check by a second qualified nurse to verify the five rights before administration.
Question 16: How should a nurse respond if a patient on a continuous 5-FU infusion via ambulatory pump reports chest pain and diaphoresis?
- Stop the infusion immediately and assess for 5-FU-associated coronary vasospasm (Correct answer)
- Reassure the patient that these are expected side effects and continue the infusion
- Discontinue the IV access and send the patient to the ED without stopping the pump
- Slow the infusion rate and administer a PRN analgesic
Correct answer: Stop the infusion immediately and assess for 5-FU-associated coronary vasospasm
5-Fluorouracil can cause coronary vasospasm presenting as angina or myocardial ischemia, requiring immediate pump cessation and cardiac evaluation.
Question 17: A terminally ill cancer patient reports existential distress and loss of meaning. Which supportive care approach is MOST appropriate?
- Increase opioid doses to reduce psychological discomfort
- Refer exclusively to psychiatry for pharmacological management
- Reassure the patient that these feelings will resolve after treatment
- Initiate dignity therapy or meaning-centered counseling with palliative care support (Correct answer)
Correct answer: Initiate dignity therapy or meaning-centered counseling with palliative care support
Dignity therapy and meaning-centered counseling are evidence-based psychotherapeutic interventions specifically designed to address existential distress in terminally ill patients.
Question 18: Which element is REQUIRED for a patient to provide valid informed consent for clinical trial participation?
- Presence of a family member to co-sign the consent form
- Voluntary participation, disclosure of all risks and benefits, and patient comprehension (Correct answer)
- Written consent obtained within 24 hours of enrollment
- Physician presence is required and the nurse cannot witness consent
Correct answer: Voluntary participation, disclosure of all risks and benefits, and patient comprehension
Valid informed consent requires voluntary participation free from coercion, full disclosure of risks and benefits, and confirmation that the patient understands the information.
Question 19: A nurse is preparing to access an implanted port. Which action is ESSENTIAL to prevent infection?
- Use a non-coring Huber needle with strict aseptic technique (Correct answer)
- Use the smallest gauge needle available
- Palpate the port without gloves to locate the septum accurately
- Clean the site with povidone-iodine and allow it to dry for 30 seconds
Correct answer: Use a non-coring Huber needle with strict aseptic technique
A non-coring Huber needle is required to access implanted ports without coring the silicone septum, and strict aseptic technique prevents catheter-related bloodstream infections.
Question 20: Which assessment scale is MOST appropriate for evaluating pain in an oncology patient with moderate cognitive impairment?
- McGill Pain Questionnaire
- Visual Analog Scale (VAS)
- PAINAD (Pain Assessment in Advanced Dementia) scale (Correct answer)
- Numeric Rating Scale (NRS) 0-10
Correct answer: PAINAD (Pain Assessment in Advanced Dementia) scale
The PAINAD scale assesses pain through behavioral indicators (breathing, vocalization, facial expression, body language, consolability) in patients who cannot self-report reliably.
Question 21: A cancer patient on opioids and vincristine develops abdominal distension, absence of bowel sounds, and no bowel movement in 5 days. What complication is suspected?
- Ileus/bowel obstruction from vincristine-induced neurotoxicity (Correct answer)
- Bowel perforation
- Chemotherapy-induced diarrhea
- Peritoneal carcinomatosis
Correct answer: Ileus/bowel obstruction from vincristine-induced neurotoxicity
Vincristine causes autonomic neuropathy leading to paralytic ileus, particularly when combined with opioids, presenting with absent bowel sounds and obstipation.
Question 22: A patient 48 hours post-chemotherapy develops fever of 101.5°F, chills, and an ANC of 300/mm³. What is the nurse's IMMEDIATE priority?
- Administer acetaminophen and reassess in 2 hours
- Increase oral fluid intake and monitor temperature every 4 hours
- Isolate the patient and await the provider's morning rounds
- Obtain blood cultures and initiate broad-spectrum antibiotics within 60 minutes per protocol (Correct answer)
Correct answer: Obtain blood cultures and initiate broad-spectrum antibiotics within 60 minutes per protocol
Febrile neutropenia is a life-threatening emergency; blood cultures must be obtained and broad-spectrum antibiotics initiated within 60 minutes of fever onset.
Question 23: A patient is being screened for a clinical trial and is found to have a liver function test that exceeds the protocol's eligibility criteria. What does the nurse understand about this?
- The PI can waive the exclusion criterion for a qualified patient
- The patient cannot be enrolled; eligibility criteria are legally binding safety parameters that cannot be waived (Correct answer)
- The patient may enroll with a signed consent acknowledging the deviation
- The exclusion applies only to the first 2 cycles and can be re-evaluated
Correct answer: The patient cannot be enrolled; eligibility criteria are legally binding safety parameters that cannot be waived
Clinical trial eligibility criteria are binding safety and scientific parameters established in the protocol; enrollment of ineligible patients constitutes a protocol deviation or violation.
Question 24: A patient on FOLFOX develops grade 3 peripheral neuropathy. Which agent in this regimen is most responsible?
- Leucovorin, due to excessive folate accumulation in nerve cells
- 5-Fluorouracil, due to its pyrimidine analog interference with neural RNA
- Oxaliplatin, due to platinum-DNA adducts in dorsal root ganglion neurons (Correct answer)
- Both agents contribute equally through synergistic neurotoxicity
Correct answer: Oxaliplatin, due to platinum-DNA adducts in dorsal root ganglion neurons
Oxaliplatin causes cumulative sensory peripheral neuropathy by forming platinum-DNA adducts in dorsal root ganglion neurons, which accumulate with repeated dosing.
Question 25: Which situation BEST describes a breach of professional boundaries by an oncology nurse?
- Attending a patient's memorial service with the family's permission
- Providing the personal phone number to a patient for after-hours contact (Correct answer)
- Sitting with a distressed patient during a chemotherapy infusion
- Accepting a small gift basket from a patient's family after discharge
Correct answer: Providing the personal phone number to a patient for after-hours contact
Sharing personal contact information crosses professional boundaries by blurring the therapeutic relationship.
Question 26: Which mechanism explains why irinotecan is considered a prodrug?
- Gut bacteria convert it to a glucuronide that re-enters circulation
- It must be converted by carboxylesterase to the active metabolite SN-38 (Correct answer)
- It requires hepatic CYP3A4 to form its active epoxide form
- It is activated by tumor hypoxia through nitroreduction
Correct answer: It must be converted by carboxylesterase to the active metabolite SN-38
Irinotecan is a prodrug converted by carboxylesterase enzymes to SN-38, its active topoisomerase I inhibitor metabolite.
Question 27: A patient receiving gemcitabine has tumor cells that upregulate ribonucleotide reductase. What is the clinical implication?
- Enhanced conversion of gemcitabine to its active triphosphate form, increasing cytotoxicity
- Resistance to gemcitabine because ribonucleotide reductase can overcome the deoxynucleotide pool depletion (Correct answer)
- Greater sensitivity to gemcitabine through synthetic lethality with the DHFR pathway
- Increased incorporation of gemcitabine into DNA due to competition with natural substrates
Correct answer: Resistance to gemcitabine because ribonucleotide reductase can overcome the deoxynucleotide pool depletion
Gemcitabine diphosphate inhibits ribonucleotide reductase; overexpression of this enzyme overcomes the drug-induced dNTP pool depletion, conferring resistance.
Question 28: Which antiemetic class is MOST effective for preventing acute chemotherapy-induced nausea and vomiting (CINV) caused by highly emetogenic regimens?
- 5-HT3 receptor antagonists (ondansetron) (Correct answer)
- Dopamine antagonists (metoclopramide)
- Antihistamines (diphenhydramine)
- Corticosteroids alone
Correct answer: 5-HT3 receptor antagonists (ondansetron)
5-HT3 receptor antagonists are first-line agents for preventing acute CINV from highly emetogenic chemotherapy regimens.
Question 29: How long should a nurse flush an implanted port access needle with normal saline to confirm patency BEFORE administering a vesicant chemotherapy agent?
- 1-2 mL to confirm flow
- Flush until blood return is confirmed, then no saline flush needed
- 5 mL rapidly to clear the needle
- At least 10 mL while assessing for any resistance, swelling, or patient discomfort (Correct answer)
Correct answer: At least 10 mL while assessing for any resistance, swelling, or patient discomfort
A minimum 10 mL saline flush administered slowly while assessing for resistance, swelling, and patient discomfort confirms port patency before vesicant administration.
Question 30: The nurse suspects a PICC line has migrated based on the patient's complaint of gurgling sounds in the ear during infusion. What does this indicate?
- The patient has developed atrial fibrillation
- Catheter tip has migrated into the jugular vein (Correct answer)
- Normal catheter sounds during infusion
- Air in the infusion line
Correct answer: Catheter tip has migrated into the jugular vein
Gurgling or swishing sounds in the ear during PICC infusion indicate catheter tip migration into the jugular vein, requiring imaging confirmation and repositioning.
Question 31: A nurse administers rasburicase to a patient for tumor lysis syndrome prophylaxis. Which laboratory precaution is ESSENTIAL?
- Check BUN and creatinine before and after each dose
- Monitor potassium levels every 2 hours post-administration
- Monitor blood glucose levels for hypoglycemia
- Draw uric acid samples in pre-chilled tubes and transport on ice immediately (Correct answer)
Correct answer: Draw uric acid samples in pre-chilled tubes and transport on ice immediately
Rasburicase continues to enzymatically degrade uric acid ex-vivo at room temperature; samples must be collected in pre-chilled tubes and transported on ice to ensure accurate results.
