ONS/ONCC Chemotherapy Immunotherapy Certificate (OCC) — Questions and Answers
Question 1: A nurse notes that a patient's carboplatin dose is calculated using the Calvert formula. What parameter does this formula use that differs from standard BSA-based dosing?
- Calvert formula doses to a target AUC using creatinine clearance (GFR), since carboplatin is almost entirely renally eliminated (Correct answer)
- Calvert formula adjusts for hepatic function using Child-Pugh score since carboplatin undergoes biliary excretion
- Calvert formula uses tumor volume measured by CT scan to optimize cytotoxic exposure
- Calvert formula uses body weight and serum albumin to estimate volume of distribution for platinum
Correct answer: Calvert formula doses to a target AUC using creatinine clearance (GFR), since carboplatin is almost entirely renally eliminated
The Calvert formula (Dose = Target AUC × [GFR + 25]) accounts for carboplatin's near-complete renal elimination, ensuring appropriate exposure regardless of individual variation in renal function.
Question 2: Which sleep hygiene strategy has the STRONGEST evidence for managing insomnia in cancer patients?
- Long-term benzodiazepine use as first-line therapy
- Cognitive behavioral therapy for insomnia (CBT-I) (Correct answer)
- Daytime naps of 3+ hours to compensate for nighttime sleep loss
- Melatonin supplementation as the only non-pharmacologic intervention
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 3: A patient receives vincristine 2 mg IV. The nurse notes the order did not specify a route. Which action is most appropriate?
- Administer it intrathecally as an alternate safe route
- Give it orally since no route was specified
- Hold the dose and clarify the route with the prescriber (Correct answer)
- Administer IV as vincristine is always given IV
Correct answer: Hold the dose and clarify the route with the prescriber
Vincristine is fatal if given intrathecally, so any ambiguity in the route must be clarified before administration to prevent a catastrophic medication error.
Question 4: 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
- mTOR inhibitors
- Monoclonal antibodies
- Tyrosine kinase inhibitors (TKIs) (Correct answer)
Correct answer: Tyrosine kinase inhibitors (TKIs)
Tyrosine kinase inhibitors like imatinib directly block BCR-ABL, the constitutively active kinase driving CML proliferation.
Question 5: Which symptom requires immediate attention during chemotherapy infusion?
- Mild nausea
- Fatigue
- Loss of appetite
- Shortness of breath (Correct answer)
Correct answer: Shortness of breath
Shortness of breath during chemotherapy infusion can indicate a serious adverse reaction, such as an allergic reaction, pulmonary toxicity, or fluid overload, which requires immediate medical intervention. While fatigue, mild nausea, and loss of appetite are common side effects, shortness of breath signals a potentially life-threatening emergency that demands prompt assessment and action.
Question 6: A patient with a PICC line develops pain, erythema, and a palpable cord along the arm. What complication does the nurse suspect?
- Air embolism
- Thrombophlebitis (Correct answer)
- Catheter migration
- Catheter occlusion
Correct answer: Thrombophlebitis
Pain, redness, and a palpable cord along the vessel indicate thrombophlebitis, a known complication of PICC lines requiring immediate evaluation.
Question 7: Which lab value is the MOST critical to monitor for bone marrow suppression in a patient receiving myelosuppressive chemotherapy?
- Total bilirubin
- Absolute neutrophil count (ANC) (Correct answer)
- Serum sodium
- Serum albumin
Correct answer: Absolute neutrophil count (ANC)
The ANC is the primary indicator of neutropenia risk and infection susceptibility in patients receiving myelosuppressive chemotherapy.
Question 8: Which document outlines the ethical principles for conducting research involving human subjects and forms the foundation of clinical trial ethics in the US?
- Nuremberg Code
- Belmont Report (Correct answer)
- Declaration of Helsinki
- Common Rule (45 CFR 46)
Correct answer: Belmont Report
The Belmont Report (1979) established the foundational ethical principles of respect for persons, beneficence, and justice for all US federally funded human subjects research.
Question 9: A patient's oncologist recommends a treatment listed as Category 1 in the NCCN Guidelines. What does this designation mean?
- High-level evidence with uniform consensus that the recommendation is appropriate (Correct answer)
- The treatment is experimental and only available in clinical trials
- Expert opinion supports this as a preferred option with limited evidence
- The treatment is approved by the FDA for this indication
Correct answer: High-level evidence with uniform consensus that the recommendation is appropriate
NCCN Category 1 designations indicate high-level evidence (usually from RCTs) with uniform consensus among NCCN panel members supporting the recommendation.
Question 10: A patient with a power-injectable PICC requires a CT scan with contrast. What is the nurse's responsibility before the procedure?
- Remove the PICC before the scan to prevent malfunction
- Confirm the PICC is rated for power injection and document the maximum pressure and flow rate (Correct answer)
- Flush the PICC with heparin before the scan
- Instruct the radiologist to use peripheral access for contrast only
Correct answer: Confirm the PICC is rated for power injection and document the maximum pressure and flow rate
Power-injectable PICCs must be confirmed as rated for contrast injection, with maximum pressure and flow rate documented to prevent catheter rupture.
Question 11: Which position should the nurse place a patient in if air embolism is suspected during central line removal?
- High Fowler's position
- Right lateral decubitus
- Supine with legs elevated
- Left lateral Trendelenburg (Durant's maneuver) (Correct answer)
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 12: Which nutritional assessment parameter is most sensitive for detecting early malnutrition in chemotherapy patients?
- Total lymphocyte count below 1500 cells/mm³
- Body mass index (BMI) below 18.5
- Unintentional weight loss of >5% in one month (Correct answer)
- Serum albumin level below 3.5 g/dL
Correct answer: Unintentional weight loss of >5% in one month
Unintentional weight loss of >5% in one month is the most sensitive early indicator of malnutrition and nutritional risk in cancer patients receiving chemotherapy.
Question 13: Which patient statement about managing chemotherapy-induced constipation indicates a need for further teaching?
- I will use a stimulant laxative as directed by my provider
- I should take an over-the-counter enema if I miss more than one day (Correct answer)
- I will report any abdominal pain or bloating to my nurse
- I will increase my fiber intake and fluid consumption
Correct answer: I should take an over-the-counter enema if I miss more than one day
Enemas are contraindicated in neutropenic or thrombocytopenic cancer patients due to risk of infection and rectal bleeding.
Question 14: Which chemotherapy agent requires extra caution with peripheral IV administration due to its extreme vesicant properties?
- Cyclophosphamide
- Vincristine (Correct answer)
- 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 15: A nurse is preparing to access an implanted port. Which action is ESSENTIAL to prevent infection?
- Use the smallest gauge needle available
- Clean the site with povidone-iodine and allow it to dry for 30 seconds
- 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 is the MOST appropriate initial nursing intervention for a patient who develops cardiac tamponade from a malignant pericardial effusion?
- Place the patient supine and administer nitroglycerin
- Administer IV furosemide to reduce fluid accumulation
- Initiate CPR immediately
- Position the patient upright, administer IV fluids, and prepare for emergency pericardiocentesis (Correct answer)
Correct answer: Position the patient upright, administer IV fluids, and prepare for emergency pericardiocentesis
Cardiac tamponade requires upright positioning to optimize venous return, IV fluids to maintain preload, and preparation for emergency pericardiocentesis to relieve pressure.
Question 17: 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?
- Respect the patient's religious autonomy, involve a chaplain, and explore non-sedating symptom management alternatives (Correct answer)
- Override the patient's decision because comfort is the primary goal of hospice
- Document the refusal and take no further action
- Consult psychiatry for assessment of decision-making capacity
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 18: A patient with advanced cancer is being discharged with a PCA pump for home pain management. Which education point is MOST critical for caregiver safety?
- The PCA can be used by anyone in the home for breakthrough pain management
- Caregivers may press the PCA button for the patient when they appear uncomfortable
- Caregivers should increase the basal rate if the patient's pain is uncontrolled
- Only the patient should press the PCA button; caregiver-controlled dosing increases overdose risk (Correct answer)
Correct answer: Only the patient should press the PCA button; caregiver-controlled dosing increases overdose risk
PCA is designed for patient-only activation; caregiver- or nurse-activated dosing bypasses the safety feature that prevents dosing while the patient is sedated, risking respiratory depression.
Question 19: Which type of IV access is preferred for vesicant chemotherapy drugs?
- Central venous catheter (Correct answer)
- Peripheral short catheter
- Midline catheter
- Butterfly needle
Correct answer: Central venous catheter
Vesicant chemotherapy drugs can cause severe tissue damage, including blistering, necrosis, and ulceration, if they extravasate (leak) into surrounding tissues. A central venous catheter (CVC) is preferred for these drugs because it provides direct access to a large vein. This minimizes the risk of extravasation and ensures safe and effective delivery of the medication.
Question 20: 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
- Urinary tract infection
- Hemorrhagic cystitis from acrolein metabolite accumulation (Correct answer)
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 21: A patient's implanted port is not flushing easily and has resistance. The nurse suspects an occlusion. Which intervention should be attempted FIRST?
- Remove and replace the Huber needle
- Reposition the patient (raise arm, cough, or change position) and reattempt (Correct answer)
- Force flush with 20 mL normal saline
- Administer alteplase (tPA) immediately
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 22: A patient reports severe burning at the IV site during vincristine infusion. The nurse notes swelling and blanching. What is the IMMEDIATE action?
- Slow the infusion rate and apply ice
- Stop the infusion, disconnect the IV, aspirate residual drug, and notify the provider (Correct answer)
- Flush the line with normal saline forcefully
- Apply a warm compress and continue the infusion
Correct answer: Stop the infusion, disconnect the IV, aspirate residual drug, and notify the provider
These signs indicate extravasation; the infusion must be stopped immediately and residual drug aspirated before any other intervention to minimize tissue damage.
Question 23: What is the nurse's role when a patient enrolled in a blinded randomized controlled trial asks which treatment arm they are in?
- Explain the concept of blinding and that this information is protected to maintain trial integrity (Correct answer)
- Tell the patient which arm they are in if they sincerely want to know
- Unblind the patient only with physician approval
- Withdraw the patient from the trial if they continue to ask
Correct answer: Explain the concept of blinding and that this information is protected to maintain trial integrity
In blinded trials, the nurse must explain that blinding protects scientific integrity and that the information cannot be shared without compromising the trial's validity.
Question 24: A hospice patient receiving comfort-focused care requests a chemotherapy agent they saw advertised online. The nurse's MOST ethical response is to:
- Provide balanced information about the drug and explore the patient's goals of care (Correct answer)
- Arrange administration of the treatment to honor patient wishes
- Dismiss the request as unrealistic without further discussion
- Contact the insurer to determine coverage before discussing with the patient
Correct answer: Provide balanced information about the drug and explore the patient's goals of care
Ethical practice requires honest communication about treatment options while aligning interventions with the patient's goals of care.
Question 25: 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?
- High-flow oxygen regardless of saturation level
- Anxiolytics as first-line therapy
- Low-dose oral or IV opioids to reduce the sensation of breathlessness (Correct answer)
- Pursed-lip breathing exercises as the sole intervention
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 26: Which vesicant chemotherapy agent requires an antidote (dexrazoxane) if extravasation occurs?
- Cyclophosphamide
- Doxorubicin (anthracycline) (Correct answer)
- Fluorouracil (5-FU)
- Bleomycin
Correct answer: Doxorubicin (anthracycline)
Dexrazoxane (Totect) is the FDA-approved antidote specifically for anthracycline extravasation to prevent severe tissue necrosis.
Question 27: 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 exclusion applies only to the first 2 cycles and can be re-evaluated
- The patient cannot be enrolled; eligibility criteria are legally binding safety parameters that cannot be waived (Correct answer)
- The PI can waive the exclusion criterion for a qualified patient
- The patient may enroll with a signed consent acknowledging the deviation
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 28: A nurse is unfamiliar with a chemotherapy drug ordered. What is the appropriate ethical action?
- Ask a colleague to give the medication
- Skip the dose until the next shift
- Administer the drug based on past experience
- Look up the drug and clarify with a pharmacist (Correct answer)
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 29: Atezolizumab differs from pembrolizumab and nivolumab in that it targets which molecule?
- PD-1 on T cells
- PD-L1 on tumor and immune cells (Correct answer)
- LAG-3 on T cells
- CTLA-4 on T cells
Correct answer: PD-L1 on tumor and immune cells
Atezolizumab targets PD-L1 (the ligand) rather than PD-1 (the receptor), blocking the interaction from the antigen-presenting or tumor cell side.
Question 30: What is the correct flushing sequence for a positive pressure implanted port after chemotherapy administration?
- Saline → heparin → clamp while maintaining positive pressure (Correct answer)
- Heparin → saline → clamp
- Saline → clamp → heparin
- Heparin only → 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 31: Which clinical findings are characteristic of superior vena cava (SVC) syndrome in an oncology patient?
- Severe hypercalcemia, constipation, and confusion
- Facial plethora, upper extremity edema, and distended neck veins (Correct answer)
- Hypotension, bradycardia, and peripheral edema
- Bilateral leg edema and dyspnea on exertion
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 32: Which personal protective equipment (PPE) component is specifically required when administering aerosolized or nebulized hazardous drugs?
- N95 respirator or powered air-purifying respirator (PAPR) (Correct answer)
- Standard surgical mask
- Face shield alone
- Double nitrile gloves only
Correct answer: N95 respirator or powered air-purifying respirator (PAPR)
Aerosolized hazardous drugs require respiratory protection beyond a surgical mask; an N95 respirator or PAPR is required to prevent inhalation exposure.
Question 33: Which clinical presentation is most consistent with septic shock in a neutropenic oncology patient?
- 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
- Temperature of 99.8°F, tachycardia of 95 bpm, ANC of 1,500/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 34: A patient post-bone marrow transplant develops fever, diarrhea with bloody stool, and a maculopapular rash on the palms and soles. What complication is suspected?
- Chemotherapy-induced mucositis
- Cytomegalovirus colitis
- Graft-versus-host disease (GVHD) (Correct answer)

Question 35: A patient receiving irinotecan develops profuse watery diarrhea 12 hours after infusion. What is the nurse's priority action?
- Administer loperamide per protocol and monitor hydration status (Correct answer)
- Encourage increased fluid intake and reassure the patient
- Prepare for immediate hospitalization
- Administer atropine for late-onset diarrhea
Correct answer: Administer loperamide per protocol and monitor hydration status
Late-onset diarrhea from irinotecan (>24 hours post-infusion) is managed with loperamide and vigilant hydration monitoring per protocol.
Question 36: What should be done immediately after a chemotherapy spill on a countertop?
- Leave the area and wait for supervisor
- Call housekeeping services
- Use a chemotherapy spill kit (Correct answer)
- Cover it with a paper towel
Correct answer: Use a chemotherapy spill kit
A chemotherapy spill is a hazardous incident that requires immediate and specialized handling to protect staff and patients from exposure. A designated chemotherapy spill kit contains the necessary PPE, absorbent materials, and disposal bags. This allows for safe containment, cleaning, and disposal of the spilled hazardous drug according to established protocols, minimizing risk.
Question 37: Which lab value is most concerning in a chemotherapy patient?
- Platelet count of 150,000/mm³
- White blood cell count of 5,000/mm³
- Absolute neutrophil count (ANC) of 400 (Correct answer)
- Hemoglobin of 11 g/dL
Correct answer: Absolute neutrophil count (ANC) of 400
An Absolute Neutrophil Count (ANC) of 400 (or 0.4 x 10^9/L) indicates severe neutropenia, a critical side effect of chemotherapy that significantly compromises the patient's immune system. This level puts the patient at extreme risk for serious, life-threatening infections. It requires immediate medical attention and protective measures to prevent complications.
Question 38: 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?
- Peritoneal carcinomatosis
- Chemotherapy-induced diarrhea
- Bowel perforation
- Ileus/bowel obstruction from vincristine-induced neurotoxicity (Correct answer)
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 39: 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 40: A patient receiving vincristine reports inability to button a shirt and symmetric weakness in both hands. The nurse should assess for which complication?
- Vinca alkaloid-induced motor neuropathy (Correct answer)
- Raynaud's phenomenon from vasospasm
- Steroid-induced proximal myopathy
- Carpal tunnel syndrome from fluid retention
Correct answer: Vinca alkaloid-induced motor neuropathy

Question 41: Which intervention is MOST effective for managing cancer-related depression in oncology patients?
- Increasing physical activity without any pharmacotherapy
- Administering corticosteroids to improve mood
- Opioid dose reduction
- Combined pharmacotherapy (antidepressants) and psychotherapy (CBT or supportive counseling) (Correct answer)
Correct answer: Combined pharmacotherapy (antidepressants) and psychotherapy (CBT or supportive counseling)
The combination of antidepressant pharmacotherapy with psychotherapy (especially CBT) has the strongest evidence for treating cancer-related depression.
Question 42: A patient on high-dose ifosfamide becomes acutely confused, agitated, and develops visual hallucinations. What neurotoxic complication is occurring?
- Opioid toxicity
- Ifosfamide-induced encephalopathy (Correct answer)
- Electrolyte imbalance from vomiting
- Wernicke's encephalopathy
Correct answer: Ifosfamide-induced encephalopathy
Ifosfamide-induced encephalopathy is a potentially life-threatening CNS toxicity presenting with confusion, agitation, hallucinations, and seizures requiring immediate drug cessation.
Question 43: 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?
- Normal catheter sounds during infusion
- Catheter tip has migrated into the jugular vein (Correct answer)
- The patient has developed atrial fibrillation
- 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 44: 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)
- Using tissue plasminogen activator (tPA) prophylactically after every infusion
- Flushing with sterile water after each use
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 45: A patient with a new PICC line develops sudden onset of dyspnea, hypotension, and a 'sucking' sound during catheter manipulation. What complication is occurring?
- Pneumothorax
- Pulmonary embolism
- Catheter fracture
- Air embolism (Correct answer)
Correct answer: Air embolism
Air embolism can occur during open central catheter manipulation and presents with sudden dyspnea, hypotension, and a mill-wheel murmur or sucking sound.
Question 46: An oncology patient asks the nurse about expanded access (compassionate use) for an unapproved drug. What is the nurse's BEST response?
- 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
- Expanded access is not monitored by the FDA and carries no regulatory oversight
- 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)
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 47: Which factor MOST increases a patient's risk for chemotherapy extravasation injury?
- Multiple prior IV attempts in the same vein and fragile veins (Correct answer)
- Use of a large-bore peripheral IV catheter
- Slow infusion rate over 60 minutes
- Young age and good hydration status
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 48: A patient enrolled in a Phase I clinical trial asks the nurse what the primary goal of this phase is. What is the correct response?
- To confirm the drug's benefit in a large population
- To compare the new drug with the current standard of care
- To evaluate the drug's safety, tolerability, and maximum tolerated dose in humans (Correct answer)
- To determine the drug's effectiveness in treating the cancer
Correct answer: To evaluate the drug's safety, tolerability, and maximum tolerated dose in humans
Phase I trials primarily establish safety, tolerability, pharmacokinetics, and maximum tolerated dose in a small group of patients, not efficacy.
Question 49: A patient with cancer-related anorexia-cachexia syndrome asks if there are medications that can help with appetite. Which agent has FDA approval for this indication in cancer patients?
- Ondansetron
- Megestrol acetate (Megace) (Correct answer)
- Metoclopramide
- Dexamethasone at standard doses
Correct answer: Megestrol acetate (Megace)
Megestrol acetate is FDA-approved for treating anorexia and cachexia in cancer patients and promotes appetite and weight gain through progesterone receptor activity.
Question 50: Which dressing change frequency is recommended for a tunneled central venous catheter exit site according to current evidence-based guidelines?
- Every 24 hours with gauze dressing
- Only when visibly soiled or loose
- Every 7 days with transparent semi-permeable membrane dressing (unless soiled) (Correct answer)
- Every 48 hours with antimicrobial gauze
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 51: 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 52: A cancer patient receiving corticosteroids long-term for symptom management is at risk for which complication requiring prophylactic management?
- Osteoporosis, hyperglycemia, and Pneumocystis jirovecii pneumonia (PCP) (Correct answer)
- Peripheral neuropathy and cardiac arrhythmias
- Renal failure and electrolyte wasting
- Thrombocytopenia and bleeding
Correct answer: Osteoporosis, hyperglycemia, and Pneumocystis jirovecii pneumonia (PCP)
Long-term corticosteroid use in cancer patients risks osteoporosis, steroid-induced hyperglycemia, immunosuppression, and PCP, often requiring prophylactic calcium/vitamin D, glucose monitoring, and TMP-SMX.
Question 53: A patient on ifosfamide therapy reports hematuria and painful urination. Which targeted assessment finding confirms the suspected complication?
- Urine specific gravity >1.030 with dysuria
- Gross blood in urine with negative urine culture (Correct answer)
- Elevated serum creatinine with flank pain
- Positive urinalysis for leukocyte esterase and nitrites
Correct answer: Gross blood in urine with negative urine culture
Ifosfamide metabolizes to acrolein, which causes hemorrhagic cystitis presenting as gross hematuria with a negative urine culture, distinguishing it from infectious causes.
Question 54: Before administering chemotherapy through a port-a-cath, the nurse aspirates and gets no blood return. What is the MOST appropriate next step?
- Reposition the patient and try aspiration again, then administer if still no return
- Administer the chemotherapy slowly and monitor the site
- Hold the chemotherapy and notify the provider to assess catheter function (Correct answer)
- Flush with 20 mL normal saline to clear the port
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 55: A terminally ill cancer patient reports existential distress and loss of meaning. Which supportive care approach is MOST appropriate?
- Initiate dignity therapy or meaning-centered counseling with palliative care support (Correct answer)
- Increase opioid doses to reduce psychological discomfort
- Reassure the patient that these feelings will resolve after treatment
- Refer exclusively to psychiatry for pharmacological management
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 56: CDK 4/6 inhibitors such as palbociclib are approved in combination with endocrine therapy for which breast cancer subtype?
- Inflammatory breast cancer
- HER2-positive breast cancer
- Hormone receptor-positive/HER2-negative breast cancer (Correct answer)
- Triple-negative breast cancer
Correct answer: Hormone receptor-positive/HER2-negative breast cancer
CDK 4/6 inhibitors arrest cell cycle progression at the G1/S checkpoint and are approved for HR+/HER2- advanced breast cancer in combination with endocrine therapy.
Question 57: A patient with lung cancer on opioids develops progressive confusion, hyperreflexia, and seizures. Labs show serum sodium of 118 mEq/L. What is occurring?
- Tumor lysis syndrome
- Opioid toxicity
- Hypercalcemia of malignancy
- Syndrome of inappropriate antidiuretic hormone (SIADH) (Correct answer)
Correct answer: Syndrome of inappropriate antidiuretic hormone (SIADH)
SIADH causes dilutional hyponatremia with neurological manifestations; it is common in small cell lung cancer due to ectopic ADH secretion.
Question 58: A patient on methotrexate presents with a serum creatinine that has doubled from baseline. What is the nurse's primary concern?
- Hypokalemia from proximal tubular damage
- Reduced efficacy of the chemotherapy regimen
- Delayed methotrexate clearance and toxicity accumulation (Correct answer)
- Increased risk of peripheral neuropathy
Correct answer: Delayed methotrexate clearance and toxicity accumulation
Methotrexate is renally cleared, so impaired kidney function delays drug elimination and significantly increases the risk of severe toxicity including mucositis and myelosuppression.
Question 59: Which patient population is at HIGHEST risk for developing oral mucositis during chemotherapy?
- Patients receiving oral targeted therapies only
- Patients receiving high-dose methotrexate, 5-FU, or those undergoing bone marrow transplant conditioning (Correct answer)
- Patients receiving immunotherapy checkpoint inhibitors
- Patients receiving hormonal therapy for breast cancer
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 60: 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?
- Apply a warm compress and continue monitoring
- Increase the infusion rate to complete the dose on schedule
- Stop the infusion, assess for extravasation, and notify the provider (Correct answer)
- Reset the pump alarm and reassess in 30 minutes
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 61: 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)
- Administer a saline enema daily
- Increase dietary fiber intake to 30g/day
- Discontinue the opioid and switch to NSAIDs
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 62: Trastuzumab (Herceptin) targets which receptor overexpressed in HER2-positive breast cancer?
- HER3
- VEGFR-2
- EGFR (HER1)
- HER2/neu (ErbB2) (Correct answer)
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 63: 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 64: 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
- Voluntary participation, disclosure of all risks and benefits, and patient comprehension (Correct answer)
- Written consent obtained within 24 hours of enrollment
- 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 65: 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)
- Withdraw the patient from the study before reporting
- 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 66: 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?
- Deep vein thrombosis
- Chemotherapy-induced peripheral neuropathy
- Leptomeningeal carcinomatosis
- Spinal cord compression from epidural metastasis (Correct answer)
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 67: Which nutritional screening tool is MOST commonly recommended for oncology patients to identify malnutrition risk?
- Body Mass Index (BMI) measurement alone
- 24-hour dietary recall only
- Serum albumin level
- Patient-Generated Subjective Global Assessment (PG-SGA) (Correct answer)
Correct answer: Patient-Generated Subjective Global Assessment (PG-SGA)
The PG-SGA is the oncology-specific nutrition screening tool validated for cancer patients, assessing weight loss, food intake, symptoms, functional capacity, and physical exam findings.
Question 68: 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 increases the risk of the event by 35%
- The result is not statistically significant because the CI crosses 1.0
- The new drug reduces the risk of the event by 35%, and this is statistically significant (Correct answer)
- 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 69: 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
- Switch to non-pharmacologic methods only
- Increase the opioid dose or switch to a stronger opioid for uncontrolled moderate-to-severe pain (Correct answer)
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 70: Which quality improvement model is MOST commonly used in oncology nursing practice to implement and evaluate evidence-based changes?
- PDSA (Plan-Do-Study-Act) cycle (Correct answer)
- Failure mode and effects analysis (FMEA)
- Root cause analysis (RCA)
- 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 71: Which intervention is the MOST critical in preventing tumor lysis syndrome in high-risk patients?
- Restricting dietary potassium
- Aggressive IV hydration and allopurinol or rasburicase administration before chemotherapy (Correct answer)
- Administering calcium gluconate prophylactically
- Placing the patient on continuous telemetry only
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 72: A hospice patient with cancer develops the death rattle (noisy breathing). What is the MOST appropriate nursing intervention?
- Administer high-dose diuretics to reduce secretions
- Initiate mechanical ventilation support
- Reposition the patient, explain the sound to family, and administer anticholinergic medications if ordered (Correct answer)
- Perform aggressive oral suctioning to clear the airway
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 73: Oral chemotherapy agents such as capecitabine should be dispensed to patients with which instruction regarding handling?
- Tablets may be split with a standard pill cutter for dose adjustments
- Tablets should be handled with gloves or handled indirectly; do not crush or split unless specifically formulated to do so (Correct answer)
- Tablets can be crushed if the patient has difficulty swallowing
- Patients do not need gloves since it is an oral medication
Correct answer: Tablets should be handled with gloves or handled indirectly; do not crush or split unless specifically formulated to do so
Oral chemotherapy tablets should not be crushed or split (unless formulated as such) and caregivers should use gloves when handling them to prevent hazardous skin contact.
Question 74: Which integrative therapy has BEST evidence for reducing chemotherapy-related nausea and vomiting as a complement to antiemetics?
- Herbal supplements including ginger capsules at high doses
- Aromatherapy with peppermint oil
- Magnet therapy
- Acupuncture and acupressure (Correct answer)
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 75: A nurse wants to find the best evidence for managing chemotherapy-induced nausea. Which resource provides the MOST credible, peer-reviewed clinical practice guidelines?
- General internet search engines
- Patient advocacy websites
- ASCO, ONS, or NCCN clinical practice guidelines (Correct answer)
- Pharmaceutical manufacturer prescribing information only
Correct answer: ASCO, ONS, or NCCN clinical practice guidelines
Professional organization guidelines from ASCO, ONS, and NCCN are developed through systematic evidence review and expert consensus, providing the most credible clinical practice guidance.
