ONS/ONCC Chemotherapy Immunotherapy Certificate (OCC) — Questions and Answers
Question 1: Which integrative therapy has BEST evidence for reducing chemotherapy-related nausea and vomiting as a complement to antiemetics?
- Acupuncture and acupressure (Correct answer)
- Herbal supplements including ginger capsules at high doses
- Magnet therapy
- 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 2: 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
- At least 10 mL while assessing for any resistance, swelling, or patient discomfort (Correct answer)
- 5 mL rapidly to clear the needle
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 3: A terminally ill cancer patient reports existential distress and loss of meaning. Which supportive care approach is MOST appropriate?
- Refer exclusively to psychiatry for pharmacological management
- Increase opioid doses to reduce psychological discomfort
- Initiate dignity therapy or meaning-centered counseling with palliative care support (Correct answer)
- Reassure the patient that these feelings will resolve after treatment
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 4: Which position should the nurse place a patient in if air embolism is suspected during central line removal?
- High Fowler's position
- Left lateral Trendelenburg (Durant's maneuver) (Correct answer)
- Right lateral decubitus
- Supine with legs elevated
Correct answer: Left lateral Trendelenburg (Durant's maneuver)
Left lateral Trendelenburg (Durant's maneuver) traps air in the right ventricle apex to prevent it from entering the pulmonary vasculature.
Question 5: 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
- Combining current best evidence, clinical expertise, and patient preferences to guide implementation (Correct answer)
- Implementing the protocol only after all staff agree it is superior
- 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 6: A patient receiving fludarabine for CLL develops profound lymphopenia with opportunistic infections. Which mechanism accounts for fludarabine's profound immunosuppression?
- Fludarabine inhibits IL-2 receptor signaling, preventing lymphocyte proliferation without affecting lymphocyte survival
- Fludarabine's active metabolite F-ara-ATP incorporates into DNA and RNA of lymphocytes and inhibits DNA polymerase, causing selective T-cell depletion lasting months (Correct answer)
- Fludarabine crosslinks immunoglobulin heavy chains, depleting B cells through antibody aggregation
- Fludarabine activates mTOR in T-regulatory cells, causing paradoxical immune suppression
Correct answer: Fludarabine's active metabolite F-ara-ATP incorporates into DNA and RNA of lymphocytes and inhibits DNA polymerase, causing selective T-cell depletion lasting months
Fludarabine's active triphosphate metabolite (F-ara-ATP) inhibits DNA polymerase and incorporates into DNA/RNA, causing prolonged lymphopenia particularly of CD4+ T-cells, predisposing to opportunistic infections.
Question 7: When evaluating pain in oncology patients, which assessment approach best aligns with evidence-based practice?
- Rely primarily on behavioral observation rather than self-report
- Use a standardized tool and reassess within 30–60 minutes after intervention (Correct answer)
- Assess pain only when the patient verbally reports discomfort
- Document pain as the fifth vital sign without reassessment
Correct answer: Use a standardized tool and reassess within 30–60 minutes after intervention
Best practice requires using a validated pain scale, administering the intervention, and reassessing within 30–60 minutes to evaluate efficacy and guide further management.
Question 8: A patient with multiple myeloma develops confusion, polyuria, constipation, and a serum calcium of 13.5 mg/dL. What is the initial treatment priority?
- Administer loop diuretics without IV fluids
- Administer oral calcium supplements to correct the imbalance
- Initiate bisphosphonate therapy as the first intervention
- Begin aggressive IV normal saline hydration to promote calciuresis (Correct answer)
Correct answer: Begin aggressive IV normal saline hydration to promote calciuresis
Aggressive IV hydration with normal saline is the first-line treatment for hypercalcemia of malignancy, promoting renal calcium excretion before adding bisphosphonates.
Question 9: The nurse is educating a patient with a tunneled Hickman catheter about home care. Which instruction is MOST important?
- Remove the dressing daily to inspect the exit site
- Submerge the catheter in water briefly during bathing
- Change the cap and flush the catheter per the prescribed protocol, and report fever above 100.4°F (Correct answer)
- Clamp the catheter only during dressing changes
Correct answer: Change the cap and flush the catheter per the prescribed protocol, and report fever above 100.4°F
Fever above 100.4°F in a patient with a tunneled catheter is a red flag for catheter-related bloodstream infection requiring immediate reporting.
Question 10: Which assessment scale is MOST appropriate for evaluating pain in an oncology patient with moderate cognitive impairment?
- Visual Analog Scale (VAS)
- McGill Pain Questionnaire
- Numeric Rating Scale (NRS) 0-10
- PAINAD (Pain Assessment in Advanced Dementia) scale (Correct answer)
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 11: 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 12: Which document establishes legal authority for a surrogate decision-maker when an oncology patient loses decision-making capacity?
- DNR order
- Advance directive living will
- Physician order for life-sustaining treatment (POLST)
- Durable power of attorney for healthcare (Correct answer)
Correct answer: Durable power of attorney for healthcare
A durable power of attorney for healthcare legally designates a surrogate to make medical decisions when the patient lacks capacity.
Question 13: 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?
- Document the refusal and take no further action
- Override the patient's decision because comfort is the primary goal of hospice
- Consult psychiatry for assessment of decision-making capacity
- Respect the patient's religious autonomy, involve a chaplain, and explore non-sedating symptom management alternatives (Correct answer)
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 14: Which finding indicates a patient with cancer-associated hypercoagulability has developed a pulmonary embolism (PE)?
- Fever and productive cough with purulent sputum
- Gradual onset of bilateral leg edema over 3 days
- Abdominal pain and flank tenderness
- Sudden dyspnea, pleuritic chest pain, and tachycardia (Correct answer)
Correct answer: Sudden dyspnea, pleuritic chest pain, and tachycardia
Sudden dyspnea, pleuritic chest pain, and tachycardia are the classic triad of pulmonary embolism, a common life-threatening complication in cancer patients due to hypercoagulability.
Question 15: 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 new drug reduces the risk of the event by 35%, and this is statistically significant (Correct answer)
- The result is not statistically significant because the CI crosses 1.0
- The new drug increases the risk of the event by 35%
- The drug has no effect because the HR is less than 1.0
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 16: Which element is REQUIRED for a patient to provide valid informed consent for clinical trial participation?
- 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)
- Presence of a family member to co-sign the consent form
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 17: A patient undergoing aggressive chemotherapy for leukemia develops hyperkalemia, hyperphosphatemia, hypocalcemia, and elevated uric acid. What syndrome is occurring?
- Tumor lysis syndrome (Correct answer)
- Disseminated intravascular coagulation
- Syndrome of inappropriate antidiuretic hormone
- Hypercalcemia of malignancy
Correct answer: Tumor lysis syndrome
Tumor lysis syndrome results from rapid destruction of cancer cells releasing intracellular contents, causing the classic electrolyte pattern of hyperkalemia, hyperphosphatemia, hypocalcemia, and hyperuricemia.
Question 18: Blinatumomab is a bispecific T-cell engager (BiTE) that simultaneously binds CD19 on B cells and which molecule on T cells?
- PD-1
- CD28
- CTLA-4
- CD3 (Correct answer)
Correct answer: CD3
Blinatumomab bridges CD19-expressing malignant B cells and CD3-expressing T cells, forcing T cells to recognize and destroy the B cell tumor targets.
Question 19: A nurse notes an unexpected serious adverse event in a patient on a clinical trial. What is the MOST important immediate action?
- Withdraw the patient from the study before reporting
- Document the event in the chart, report to the principal investigator immediately, and complete the adverse event report per protocol (Correct answer)
- Report directly to the FDA without involving the PI
- Report the adverse event to the IRB within 10 business days
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 20: A patient on long-term opioid therapy for cancer pain develops opioid-induced constipation unresponsive to stimulant laxatives. What is the MOST appropriate next intervention?
- Administer methylnaltrexone (Relistor) to reverse peripheral opioid effects in the GI tract (Correct answer)
- Discontinue the opioid and switch to NSAIDs
- Increase dietary fiber intake to 30g/day
- Administer a saline enema daily
Correct answer: Administer methylnaltrexone (Relistor) to reverse peripheral opioid effects in the GI tract
Methylnaltrexone is a peripherally acting mu-opioid receptor antagonist that reverses opioid-induced constipation without crossing the blood-brain barrier to reverse analgesia.
Question 21: Which situation BEST describes a breach of professional boundaries by an oncology nurse?
- Accepting a small gift basket from a patient's family after discharge
- 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
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 22: Which dressing change frequency is recommended for a tunneled central venous catheter exit site according to current evidence-based guidelines?
- 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)
- Only when visibly soiled or loose
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 23: Which intervention helps prevent fibrin sheath formation on a central venous catheter?
- Filling the catheter lumen with ethanol between uses
- Flushing with 10 mL normal saline using a pulsatile push technique after each use (Correct answer)
- Flushing with sterile water after each use
- Using tissue plasminogen activator (tPA) prophylactically after every infusion
Correct answer: Flushing with 10 mL normal saline using a pulsatile push technique after each use
Pulsatile flushing with normal saline creates turbulence that dislodges debris and prevents fibrin accumulation on catheter walls.
Question 24: A patient receiving gemcitabine presents with fever of 39.2°C (102.6°F), dyspnea, and bilateral pulmonary infiltrates 48 hours after infusion. The nurse should suspect:
- Gemcitabine-induced pulmonary toxicity (Correct answer)
- Transfusion-related acute lung injury from a prior transfusion
- Hospital-acquired pneumonia requiring antibiotics
- Pulmonary embolism from hypercoagulable state
Correct answer: Gemcitabine-induced pulmonary toxicity
Gemcitabine can cause severe pulmonary toxicity presenting as acute respiratory distress with bilateral infiltrates temporally related to drug administration.
Question 25: What is the correct flushing sequence for a positive pressure implanted port after chemotherapy administration?
- Heparin only → clamp
- Saline → clamp → heparin
- Saline → heparin → clamp while maintaining positive pressure (Correct answer)
- Heparin → saline → clamp
Correct answer: Saline → heparin → clamp while maintaining positive pressure
The correct sequence is saline flush followed by heparin lock while maintaining positive pressure to prevent blood backflow and clot formation in the port.
Question 26: Which psychosocial assessment tool is recommended by ONS for identifying depression and anxiety in oncology patients receiving chemotherapy?
- Hamilton Rating Scale for Depression (HAM-D)
- Beck Anxiety Inventory (BAI)
- Distress Thermometer with Problem List (Correct answer)
- Mini-Mental State Examination (MMSE)
Correct answer: Distress Thermometer with Problem List
The NCCN Distress Thermometer with Problem List is a validated, quick screening tool recommended for identifying psychosocial distress in oncology patients.
Question 27: Which clinical findings are characteristic of superior vena cava (SVC) syndrome in an oncology patient?
- Severe hypercalcemia, constipation, and confusion
- Bilateral leg edema and dyspnea on exertion
- Hypotension, bradycardia, and peripheral edema
- Facial plethora, upper extremity edema, and distended neck veins (Correct answer)
Correct answer: Facial plethora, upper extremity edema, and distended neck veins
SVC syndrome presents with facial plethora, upper extremity and facial edema, and distended neck veins due to obstruction of venous return from the upper body.
Question 28: 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 blood glucose levels for hypoglycemia
- Monitor potassium levels every 2 hours post-administration
- 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.
Question 29: 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?
- Increase the opioid dose or switch to a stronger opioid for uncontrolled moderate-to-severe pain (Correct answer)
- Add a non-opioid adjuvant and remove the opioid
- Switch to non-pharmacologic methods only
- Reduce the opioid dose to prevent tolerance
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 30: Which chemotherapeutic agent is commonly linked with nephrotoxicity requiring pre- and post-hydration protocols?
- Etoposide
- Vincristine
- Paclitaxel
- Cisplatin (Correct answer)
Correct answer: Cisplatin
Cisplatin is nephrotoxic and necessitates aggressive IV hydration to prevent renal damage.
Question 31: Which dietary instruction is MOST appropriate for a patient with chemotherapy-induced taste alterations (dysgeusia)?
- Eat only bland, flavorless foods
- Increase salt intake to mask metallic tastes
- Avoid all protein sources until taste normalizes
- Experiment with cold or room-temperature foods and plastic utensils (Correct answer)
Correct answer: Experiment with cold or room-temperature foods and plastic utensils
Cold or room-temperature foods produce fewer odors and metallic tastes, and plastic utensils reduce the metallic taste often associated with chemotherapy.
