ONS/ONCC Chemotherapy Immunotherapy Certificate (OCC) — Questions and Answers

Question 1: A patient with prostate cancer metastatic to the spine develops sudden onset of lower extremity weakness and urinary retention. What emergency should the nurse suspect?

Leptomeningeal carcinomatosis
Deep vein thrombosis
Spinal cord compression from epidural metastasis (Correct answer)
Chemotherapy-induced peripheral neuropathy

Correct answer: Spinal cord compression from epidural metastasis

New neurological deficits and urinary retention in a cancer patient with spinal metastases indicate malignant spinal cord compression, a neurological emergency requiring immediate intervention.

Question 2: Which quality improvement model is MOST commonly used in oncology nursing practice to implement and evaluate evidence-based changes?

Root cause analysis (RCA)
PDSA (Plan-Do-Study-Act) cycle (Correct answer)
Failure mode and effects analysis (FMEA)
Six Sigma DMAIC

Correct answer: PDSA (Plan-Do-Study-Act) cycle

The PDSA cycle is the most widely used quality improvement model in nursing and oncology practice for iterative, evidence-based practice change.

Question 3: Which sleep hygiene strategy has the STRONGEST evidence for managing insomnia in cancer patients?

Long-term benzodiazepine use as first-line therapy
Melatonin supplementation as the only non-pharmacologic intervention
Daytime naps of 3+ hours to compensate for nighttime sleep loss
Cognitive behavioral therapy for insomnia (CBT-I) (Correct answer)

Correct answer: Cognitive behavioral therapy for insomnia (CBT-I)

CBT-I is the first-line, evidence-based treatment for insomnia in cancer patients, with sustained benefits that outlast pharmacologic interventions.

Question 4: A nurse is implementing a new evidence-based protocol for central line care. Which approach BEST demonstrates integration of evidence-based practice (EBP)?

Using only the most recent published study without consulting clinical experts
Implementing the protocol only after all staff agree it is superior
Combining current best evidence, clinical expertise, and patient preferences to guide implementation (Correct answer)
Applying the protocol as written without adaptation to the patient population

Correct answer: Combining current best evidence, clinical expertise, and patient preferences to guide implementation

Evidence-based practice integrates the best available research evidence with clinical expertise and individual patient values and preferences.

Question 5: A patient receiving a continuous 5-FU infusion via ambulatory pump reports that the pump alarmed and the site feels warm. What is the nurse's priority?

Stop the infusion, assess for extravasation, and notify the provider (Correct answer)
Reset the pump alarm and reassess in 30 minutes
Increase the infusion rate to complete the dose on schedule
Apply a warm compress and continue monitoring

Correct answer: Stop the infusion, assess for extravasation, and notify the provider

Warmth at the infusion site during chemotherapy administration suggests possible extravasation, requiring immediate cessation and assessment.

Question 6: Which factor MOST increases a patient's risk for chemotherapy extravasation injury?

Slow infusion rate over 60 minutes
Young age and good hydration status
Use of a large-bore peripheral IV catheter
Multiple prior IV attempts in the same vein and fragile veins (Correct answer)

Correct answer: Multiple prior IV attempts in the same vein and fragile veins

Fragile veins with multiple prior cannulation sites have compromised integrity, significantly increasing the risk of extravasation during chemotherapy infusion.

Question 7: What is the primary nursing goal when managing chemotherapy-induced thrombocytopenia with a platelet count of 15,000/mm³?

Administer aspirin for headache management
Encourage vigorous physical activity to stimulate platelet production
Avoid all blood draws to prevent bruising
Prevent hemorrhage through bleeding precautions and fall prevention (Correct answer)

Correct answer: Prevent hemorrhage through bleeding precautions and fall prevention

With a critically low platelet count, hemorrhage prevention through strict bleeding precautions and fall prevention is the top nursing priority.

Question 8: Which intervention is the MOST critical in preventing tumor lysis syndrome in high-risk patients?

Administering calcium gluconate prophylactically
Aggressive IV hydration and allopurinol or rasburicase administration before chemotherapy (Correct answer)
Placing the patient on continuous telemetry only
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 9: The oncology nurse is reviewing a study that reports a hazard ratio (HR) of 0.65 with a 95% CI of 0.50-0.85 for a new drug versus placebo. What does this mean?

The drug has no effect because the HR is less than 1.0
The result is not statistically significant because the CI crosses 1.0
The new drug increases the risk of the event by 35%
The new drug reduces the risk of the event by 35%, and this is statistically significant (Correct answer)

Correct answer: The new drug reduces the risk of the event by 35%, and this is statistically significant

An HR of 0.65 means a 35% reduction in the hazard (risk) of the event; since the 95% CI (0.50-0.85) does not cross 1.0, the result is statistically significant.

Question 10: Which chemotherapy agent requires extra caution with peripheral IV administration due to its extreme vesicant properties?

Vincristine (Correct answer)
Cyclophosphamide
Fluorouracil (5-FU)
Carboplatin

Correct answer: Vincristine

Vincristine is a potent vesicant that causes severe tissue necrosis on extravasation, requiring central venous access and vigilant infusion monitoring.

Question 11: A patient with advanced cancer rates their pain as 7/10 and is currently on scheduled oral morphine. Which WHO analgesic ladder principle guides the next step?

Reduce the opioid dose to prevent tolerance
Add a non-opioid adjuvant and remove the opioid
Increase the opioid dose or switch to a stronger opioid for uncontrolled moderate-to-severe pain (Correct answer)
Switch to non-pharmacologic methods only

Correct answer: Increase the opioid dose or switch to a stronger opioid for uncontrolled moderate-to-severe pain

The WHO analgesic ladder recommends stepping up to stronger opioids or increasing the current opioid dose when moderate-to-severe pain (≥7/10) is not controlled by the current regimen.

Question 12: Which clinical presentation is most consistent with septic shock in a neutropenic oncology patient?

Temperature of 99.8°F, tachycardia of 95 bpm, ANC of 1,500/mm³
Temperature of 99.0°F, normal blood pressure, ANC of 800/mm³
Temperature of 100.6°F, systolic BP of 85 mmHg despite fluid resuscitation, lactate of 3.2 mmol/L (Correct answer)
Temperature of 101°F, normal blood pressure, elevated WBC of 12,000/mm³

Correct answer: Temperature of 100.6°F, systolic BP of 85 mmHg despite fluid resuscitation, lactate of 3.2 mmol/L

Septic shock is defined by infection-related hypotension refractory to fluid resuscitation and elevated lactate (≥2 mmol/L) indicating tissue hypoperfusion.

Question 13: A patient with advanced cancer and dyspnea at rest has oxygen saturation of 94% on room air. Which intervention is MOST evidence-based for managing refractory dyspnea?

Anxiolytics as first-line therapy
Pursed-lip breathing exercises as the sole intervention
Low-dose oral or IV opioids to reduce the sensation of breathlessness (Correct answer)
High-flow oxygen regardless of saturation level

Correct answer: Low-dose oral or IV opioids to reduce the sensation of breathlessness

Low-dose opioids are the most evidence-based pharmacologic intervention for refractory dyspnea in cancer patients, regardless of oxygen saturation.

Question 14: A hospice patient with cancer develops the death rattle (noisy breathing). What is the MOST appropriate nursing intervention?

Reposition the patient, explain the sound to family, and administer anticholinergic medications if ordered (Correct answer)
Perform aggressive oral suctioning to clear the airway
Initiate mechanical ventilation support
Administer high-dose diuretics to reduce secretions

Correct answer: Reposition the patient, explain the sound to family, and administer anticholinergic medications if ordered

The death rattle results from secretions the patient can no longer clear; repositioning helps drainage, family education reduces distress, and anticholinergics (glycopyrrolate/hyoscine) reduce secretion production.

Question 15: A nurse is preparing to access an implanted port. Which action is ESSENTIAL to prevent infection?

Clean the site with povidone-iodine and allow it to dry for 30 seconds
Use the smallest gauge needle available
Palpate the port without gloves to locate the septum accurately
Use a non-coring Huber needle with strict aseptic technique (Correct answer)

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 16: Which class of targeted therapy works by inhibiting the BCR-ABL tyrosine kinase, making it effective in chronic myeloid leukemia (CML)?

CDK 4/6 inhibitors
Tyrosine kinase inhibitors (TKIs) (Correct answer)
Monoclonal antibodies
mTOR inhibitors

Correct answer: Tyrosine kinase inhibitors (TKIs)

Tyrosine kinase inhibitors like imatinib directly block BCR-ABL, the constitutively active kinase driving CML proliferation.

Question 17: A terminally ill cancer patient reports existential distress and loss of meaning. Which supportive care approach is MOST appropriate?

Reassure the patient that these feelings will resolve after treatment
Refer exclusively to psychiatry for pharmacological management
Initiate dignity therapy or meaning-centered counseling with palliative care support (Correct answer)
Increase opioid doses to reduce psychological discomfort

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: The mTOR inhibitor everolimus is FDA-approved in combination with exemestane for which indication?

Advanced prostate cancer after enzalutamide failure
Advanced HR+/HER2- breast cancer after non-steroidal aromatase inhibitor failure (Correct answer)
Renal cell carcinoma as first-line monotherapy only
Metastatic colorectal cancer as second-line therapy

Correct answer: Advanced HR+/HER2- breast cancer after non-steroidal aromatase inhibitor failure

Everolimus combined with exemestane is FDA-approved for postmenopausal women with advanced HR+/HER2- breast cancer after failure of a non-steroidal aromatase inhibitor.

Question 19: A nurse is unfamiliar with a chemotherapy drug ordered. What is the appropriate ethical action?

Administer the drug based on past experience
Look up the drug and clarify with a pharmacist (Correct answer)
Skip the dose until the next shift
Ask a colleague to give the medication

Correct answer: Look up the drug and clarify with a pharmacist

Administering medication without full knowledge is a breach of professional responsibility and patient safety. The ethical and safe action is to consult reliable drug references and clarify any uncertainties with a pharmacist or physician. This ensures the nurse administers the correct drug, dose, and route, preventing potential harm to the patient.

Question 20: A patient on chemotherapy reports a fever of 101.5°F. What should the nurse do first?

Administer acetaminophen
Notify the healthcare provider (Correct answer)
Encourage fluid intake
Apply cooling blankets

Correct answer: Notify the healthcare provider

A fever in a chemotherapy patient, especially one over 100.4°F (38°C), is a medical emergency and should be treated as neutropenic fever until proven otherwise. The nurse's first action must be to notify the healthcare provider immediately. Prompt evaluation and initiation of broad-spectrum antibiotics are crucial to prevent life-threatening sepsis in these immunocompromised patients.

Question 21: 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
Physician presence is required and the nurse cannot witness consent
Written consent obtained within 24 hours of enrollment
Voluntary participation, disclosure of all risks and benefits, and patient comprehension (Correct answer)

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 22: Which integrative therapy has BEST evidence for reducing chemotherapy-related nausea and vomiting as a complement to antiemetics?

Magnet therapy
Acupuncture and acupressure (Correct answer)
Herbal supplements including ginger capsules at high doses
Aromatherapy with peppermint oil

Correct answer: Acupuncture and acupressure

Acupuncture and acupressure (particularly at the P6/Neiguan point) have the strongest evidence base among integrative therapies for reducing chemotherapy-induced nausea.

Question 23: Before administering chemotherapy through a port-a-cath, the nurse aspirates and gets no blood return. What is the MOST appropriate next step?

Administer the chemotherapy slowly and monitor the site
Flush with 20 mL normal saline to clear the port
Reposition the patient and try aspiration again, then administer if still no return
Hold the chemotherapy and notify the provider to assess catheter function (Correct answer)

Correct answer: Hold the chemotherapy and notify the provider to assess catheter function

Lack of blood return from a port-a-cath before chemotherapy administration requires provider notification and catheter assessment to prevent extravasation of vesicant drugs.

Question 24: Which type of central venous access device is MOST appropriate for a patient requiring 6 months of intermittent chemotherapy infusions?

Implanted port (port-a-cath) (Correct answer)
Midline catheter
Non-tunneled central venous catheter
Peripheral IV catheter

Correct answer: Implanted port (port-a-cath)

An implanted port is the preferred long-term vascular access device for intermittent chemotherapy due to its durability, low infection risk, and patient comfort.

Question 25: Trastuzumab (Herceptin) targets which receptor overexpressed in HER2-positive breast cancer?

EGFR (HER1)
VEGFR-2
HER2/neu (ErbB2) (Correct answer)
HER3

Correct answer: HER2/neu (ErbB2)

Trastuzumab is a monoclonal antibody that selectively binds to the extracellular domain of HER2/neu (ErbB2), inhibiting downstream proliferative signaling.

Question 26: A patient receiving high-dose cyclophosphamide reports severe bladder pain, urinary frequency, and grossly bloody urine. What complication has occurred?

Urinary tract infection
Hemorrhagic cystitis from acrolein metabolite accumulation (Correct answer)
Bladder cancer as a late effect
Renal failure from drug nephrotoxicity

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 27: What is the primary mechanism of action of bevacizumab (Avastin)?

Inhibits EGFR signaling on tumor cells
Binds circulating VEGF to prevent tumor angiogenesis (Correct answer)
Blocks PD-1/PD-L1 immune checkpoint interaction
Inhibits mTOR complex 1 signaling

Correct answer: Binds circulating VEGF to prevent tumor angiogenesis

Bevacizumab is an anti-VEGF monoclonal antibody that sequesters VEGF in circulation, preventing it from binding its receptors and thereby inhibiting tumor angiogenesis.

Question 28: What should be closely monitored in a patient receiving high-dose methotrexate?

Vision changes
Renal function (Correct answer)
Weight gain
Hearing loss

Correct answer: Renal function

High-dose methotrexate is primarily excreted by the kidneys, making renal function monitoring absolutely critical to prevent severe toxicity. Impaired kidney function can lead to delayed drug clearance, resulting in dangerously high methotrexate levels. These elevated levels can cause severe myelosuppression, mucositis, and liver damage, necessitating careful monitoring.

Question 29: A nurse notes an unexpected serious adverse event in a patient on a clinical trial. What is the MOST important immediate action?

Document the event in the chart, report to the principal investigator immediately, and complete the adverse event report per protocol (Correct answer)
Report the adverse event to the IRB within 10 business days
Report directly to the FDA without involving the PI
Withdraw the patient from the study before reporting

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 30: A patient with leukemia post-induction chemotherapy develops disseminated intravascular coagulation (DIC). Which lab pattern is expected?

Elevated platelets, normal PT/aPTT, elevated fibrinogen
Low platelets, elevated PT/aPTT, elevated D-dimer, low fibrinogen (Correct answer)
Elevated platelets, low PT, low D-dimer
Normal PT, elevated fibrinogen, low D-dimer

Correct answer: Low platelets, elevated PT/aPTT, elevated D-dimer, low fibrinogen

DIC is characterized by simultaneous clotting and bleeding: low platelets (consumed), prolonged coagulation times, elevated D-dimer (fibrin degradation), and low fibrinogen (depleted).

Question 31: A patient receiving bleomycin develops new-onset dry cough and dyspnea. What is the nurse's FIRST action?

Stop the infusion and notify the provider immediately (Correct answer)
Administer a bronchodilator and monitor
Reassure the patient that this is a common side effect
Reduce the infusion rate by half

Correct answer: Stop the infusion and notify the provider immediately

New pulmonary symptoms in a patient receiving bleomycin may indicate pulmonary toxicity, which is potentially fatal and requires immediate cessation and provider notification.
