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

Question 1: Which intervention helps prevent fibrin sheath formation on a central venous catheter?

Filling the catheter lumen with ethanol between uses
Flushing with sterile water after each use
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

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 2: What is the primary dose-limiting toxicity of vincristine?

Myelosuppression
Nephrotoxicity
Neurotoxicity (Correct answer)
Cardiotoxicity

Correct answer: Neurotoxicity

Vincristine is associated with neurotoxicity, particularly peripheral neuropathy, which often limits its use.

Question 3: 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?

Caregivers may press the PCA button for the patient when they appear uncomfortable
The PCA can be used by anyone in the home for breakthrough pain management
Only the patient should press the PCA button; caregiver-controlled dosing increases overdose risk (Correct answer)
Caregivers should increase the basal rate if the patient's pain is uncontrolled

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 4: Which chemotherapy agent is MOST associated with hand-foot syndrome (palmar-plantar erythrodysesthesia)?

Cyclophosphamide
Capecitabine (Correct answer)
Vincristine
Carboplatin

Correct answer: Capecitabine

Capecitabine is the agent most commonly associated with hand-foot syndrome, characterized by painful redness, swelling, and blistering of the palms and soles.

Question 5: 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 6: 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
Increase opioid doses to reduce psychological discomfort
Initiate dignity therapy or meaning-centered counseling with palliative care support (Correct answer)
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 7: 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 determine the drug's effectiveness in treating the cancer
To evaluate the drug's safety, tolerability, and maximum tolerated dose in humans (Correct answer)
To confirm the drug's benefit in a large population
To compare the new drug with the current standard of care

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 8: What is the correct flushing sequence for a positive pressure implanted port after chemotherapy administration?

Saline → clamp → heparin
Heparin → saline → clamp
Heparin only → clamp
Saline → heparin → clamp while maintaining positive pressure (Correct answer)

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 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)
Mild insomnia reported by the patient
ANC of 2,000/mm³ at end of cycle
Weight loss of 2 lbs over 3 weeks

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: Cisplatin's dose-limiting toxicity is nephrotoxicity. Which pharmacological maneuver best reduces this risk?

Co-administration of probenecid to reduce renal tubular secretion of cisplatin
Alkalinization of urine to pH >7 to convert cisplatin to a less nephrotoxic hydroxylated species
Vigorous IV hydration with normal saline to maintain high urine flow and dilute tubular platinum concentrations (Correct answer)
Administration of N-acetylcysteine before each dose to chelate platinum in renal tubules

Correct answer: Vigorous IV hydration with normal saline to maintain high urine flow and dilute tubular platinum concentrations

Aggressive IV saline hydration before and after cisplatin is the standard strategy to reduce tubular platinum concentrations and prevent nephrotoxicity.

Question 11: A patient on high-dose methotrexate reports decreased urine output and dark urine. Which intervention should the nurse anticipate?

Increasing urine alkalinization with sodium bicarbonate and aggressive hydration (Correct answer)
Restricting IV fluids to prevent overload
Administering leucovorin rescue immediately without provider order
Stopping oral medications only

Correct answer: Increasing urine alkalinization with sodium bicarbonate and aggressive hydration

Urine alkalinization and aggressive hydration prevent methotrexate precipitation in the renal tubules, reducing nephrotoxicity risk.

Question 12: Trastuzumab (Herceptin) targets which receptor overexpressed in HER2-positive breast cancer?

EGFR (HER1)
HER2/neu (ErbB2) (Correct answer)
VEGFR-2
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 13: 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
Air in the infusion line
The patient has developed atrial fibrillation
Catheter tip has migrated into the jugular vein (Correct answer)

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 14: 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
Draw uric acid samples in pre-chilled tubes and transport on ice immediately (Correct answer)
Monitor potassium levels every 2 hours post-administration

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

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
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 16: 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
Switch to non-pharmacologic methods only
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)

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 17: 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)
Melatonin supplementation as the only non-pharmacologic intervention
Daytime naps of 3+ hours to compensate for nighttime sleep loss

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 18: 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
Consult psychiatry for assessment of decision-making capacity
Document the refusal and take no further action
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 19: 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?

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
Anxiolytics as first-line therapy

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 20: A patient's oncologist recommends a treatment listed as Category 1 in the NCCN Guidelines. What does this designation mean?

The treatment is approved by the FDA for this indication
High-level evidence with uniform consensus that the recommendation is appropriate (Correct answer)
Expert opinion supports this as a preferred option with limited evidence
The treatment is experimental and only available in clinical trials

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

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

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

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

Correct answer: Vincristine

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

Question 23: A patient with a PICC line develops pain, erythema, and a palpable cord along the arm. What complication does the nurse suspect?

Catheter occlusion
Catheter migration
Thrombophlebitis (Correct answer)
Air embolism

Correct answer: Thrombophlebitis

Pain, redness, and a palpable cord along the vessel indicate thrombophlebitis, a known complication of PICC lines requiring immediate evaluation.

Question 24: A patient with a power-injectable PICC requires a CT scan with contrast. What is the nurse's responsibility before the procedure?

Flush the PICC with heparin before the scan
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)
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 25: Which regulatory body provides oversight and approval for oncology clinical trials and new drug applications in the United States?

National Institutes of Health (NIH)
Food and Drug Administration (FDA) (Correct answer)
Centers for Medicare & Medicaid Services (CMS)
Joint Commission

Correct answer: Food and Drug Administration (FDA)

The FDA regulates clinical trials and approves new drugs and biologics for marketing in the United States through the Investigational New Drug (IND) and New Drug Application (NDA) processes.

Question 26: Which integrative therapy has BEST evidence for reducing chemotherapy-related nausea and vomiting as a complement to antiemetics?

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

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 27: Which clinical findings are characteristic of superior vena cava (SVC) syndrome in an oncology patient?

Hypotension, bradycardia, and peripheral edema
Bilateral leg edema and dyspnea on exertion
Facial plethora, upper extremity edema, and distended neck veins (Correct answer)
Severe hypercalcemia, constipation, and confusion

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 cancer patient receiving corticosteroids long-term for symptom management is at risk for which complication requiring prophylactic management?

Peripheral neuropathy and cardiac arrhythmias
Osteoporosis, hyperglycemia, and Pneumocystis jirovecii pneumonia (PCP) (Correct answer)
Thrombocytopenia and bleeding
Renal failure and electrolyte wasting

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 29: Which chemotherapy agent is MOST associated with anaphylaxis during infusion, requiring premedication?

Ifosfamide
Paclitaxel (Correct answer)
Fluorouracil
Methotrexate

Correct answer: Paclitaxel

Paclitaxel, formulated in Cremophor EL, frequently causes hypersensitivity reactions and requires premedication with corticosteroids, diphenhydramine, and H2 blockers.

Question 30: Which document outlines the ethical principles for conducting research involving human subjects and forms the foundation of clinical trial ethics in the US?

Common Rule (45 CFR 46)
Declaration of Helsinki
Nuremberg Code
Belmont Report (Correct answer)

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 31: During a physical assessment, a nurse notices a patient on paclitaxel has absent deep tendon reflexes in bilateral lower extremities. This finding most likely indicates:

Paraneoplastic syndrome progression
Taxane-induced peripheral neuropathy (Correct answer)
Spinal cord compression requiring urgent imaging
Electrolyte imbalance secondary to vomiting

Correct answer: Taxane-induced peripheral neuropathy

Absent deep tendon reflexes are a classic sign of peripheral neuropathy, a dose-limiting toxicity of paclitaxel and other taxanes.

Question 32: A patient's port is accessed but there is no blood return. Which action should the nurse take BEFORE infusing a vesicant chemotherapy agent?

Flush vigorously with 20 mL saline to open the port
Attempt to reposition the patient (arm raise, deep breath) and reassess; if still no blood return, do not infuse and report to the physician (Correct answer)
Administer a non-vesicant first to test patency, then switch to the vesicant
Proceed with infusion if the site appears non-swollen and the patient reports no pain

Correct answer: Attempt to reposition the patient (arm raise, deep breath) and reassess; if still no blood return, do not infuse and report to the physician

Lack of blood return from a port indicates uncertain placement and is an absolute contraindication to vesicant administration until position is confirmed, to prevent extravasation.

Question 33: A nurse is preparing to access an implanted port. Which action is ESSENTIAL to prevent infection?

Palpate the port without gloves to locate the septum accurately
Use the smallest gauge needle available
Use a non-coring Huber needle with strict aseptic technique (Correct answer)
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 34: A patient's implanted port is not flushing easily and has resistance. The nurse suspects an occlusion. Which intervention should be attempted FIRST?

Force flush with 20 mL normal saline
Reposition the patient (raise arm, cough, or change position) and reattempt (Correct answer)
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 35: What is the correct technique for removing chemotherapy-contaminated gloves to avoid self-contamination?

Remove gloves by pulling at the palm and discard palm-side up
Pull both gloves off simultaneously by the fingertips
Grasp the outer wrist of the first glove and peel inside-out, then remove the second glove touching only its inner surface (Correct answer)
Rinse gloves with water before removal to dilute any contamination

Correct answer: Grasp the outer wrist of the first glove and peel inside-out, then remove the second glove touching only its inner surface

The inside-out glove removal technique ensures the contaminated outer surface never contacts bare skin, preventing dermal exposure to hazardous drug residue.

Question 36: A patient with advanced cancer is transitioning to hospice care. What is the PRIMARY goal of hospice care?

Prolong survival at all costs with curative intent
Achieve remission using aggressive chemotherapy
Provide wound care and medication management only
Maximize comfort, dignity, and quality of life while supporting the patient and family (Correct answer)

Correct answer: Maximize comfort, dignity, and quality of life while supporting the patient and family

Hospice care's primary goal is comfort-focused care that maximizes quality of life, manages symptoms, and supports the patient and family through the dying process.

Question 37: When monitoring a patient for hypersensitivity reaction during a paclitaxel infusion, which set of symptoms occurring within the first 10 minutes indicates a severe reaction?

Mild flushing and warmth at the infusion site with normal vital signs
Chills and low-grade fever with unchanged blood pressure
Grade 1 rash confined to the chest with stable oxygen saturation
Hypotension, bronchospasm, generalized urticaria, and back pain (Correct answer)

Correct answer: Hypotension, bronchospasm, generalized urticaria, and back pain

Hypotension, bronchospasm, urticaria, and back pain within the first infusion minutes indicate a severe hypersensitivity reaction requiring immediate infusion cessation and emergency management.

Question 38: CDK 4/6 inhibitors such as palbociclib are approved in combination with endocrine therapy for which breast cancer subtype?

HER2-positive breast cancer
Hormone receptor-positive/HER2-negative breast cancer (Correct answer)
Inflammatory breast cancer
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 39: Moderate to severe immune-related adverse events (irAEs) from checkpoint inhibitors are primarily managed with:

Colony-stimulating factors to support immune recovery
Holding the checkpoint inhibitor and initiating systemic corticosteroids (Correct answer)
Dose reduction by 50% and close monitoring
Antihistamines and acetaminophen for symptomatic relief

Correct answer: Holding the checkpoint inhibitor and initiating systemic corticosteroids

Moderate to severe irAEs require holding the checkpoint inhibitor and initiating high-dose systemic corticosteroids (e.g., prednisone 1-2 mg/kg/day) to suppress aberrant immune activation.

Question 40: Which outcome measure is MOST important to patients and is increasingly required in oncology clinical trial reporting?

Pharmacokinetic parameters
Patient-reported outcomes (PROs) including quality of life (Correct answer)
Overall response rate (ORR)
Progression-free survival (PFS)

Correct answer: Patient-reported outcomes (PROs) including quality of life

Patient-reported outcomes (PROs), including quality of life measures, capture the patient's perspective on treatment burden and benefit, increasingly required by the FDA in oncology trial reporting.

Question 41: Which clinical presentation is most consistent with septic shock in a neutropenic oncology patient?

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 99.0°F, normal blood pressure, ANC of 800/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 42: A closed-system drug transfer device (CSTD) is MOST beneficial for which scenario?

Performing arterial blood gas sampling in patients receiving chemotherapy
Transferring liquid hazardous drugs between vials and syringes to prevent aerosol and spill exposure (Correct answer)
Connecting standard IV fluids that are not hazardous
Mixing oral chemotherapy capsules with juice for enteral administration

Correct answer: Transferring liquid hazardous drugs between vials and syringes to prevent aerosol and spill exposure

CSTDs mechanically prevent the escape of hazardous drug aerosols and liquid during drug transfer and administration, making them essential for IV hazardous drug preparation.

Question 43: Which position should the nurse place a patient in if air embolism is suspected during central line removal?

Left lateral Trendelenburg (Durant's maneuver) (Correct answer)
Right lateral decubitus
High Fowler's position
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 44: A nurse researcher is reviewing a meta-analysis on antiemetic efficacy. What does this study design involve?

Prospective observation of a patient cohort without an intervention
A single large RCT with pre-specified interim analyses
Statistical pooling of results from multiple independent studies on the same question (Correct answer)
An expert panel review of case reports

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 45: Doxorubicin's cardiotoxicity is primarily attributed to which mechanism?

Inhibition of cardiac-specific Na+/K+ ATPase leading to calcium overload
Reactive oxygen species generated by iron-anthracycline complexes causing mitochondrial damage and cardiomyocyte apoptosis (Correct answer)
Cross-reactivity of anthracycline antibodies with cardiac myosin heavy chain
Direct inhibition of cardiac topoisomerase IIβ leading to DNA double-strand breaks in cardiomyocytes

Correct answer: Reactive oxygen species generated by iron-anthracycline complexes causing mitochondrial damage and cardiomyocyte apoptosis

Doxorubicin chelates iron and undergoes redox cycling to generate reactive oxygen species, causing mitochondrial dysfunction and irreversible cardiomyocyte apoptosis.

Question 46: Which of the following actions by an oncology nurse BEST exemplifies the ethical principle of veracity?

Clearly explaining treatment risks even when the news is difficult (Correct answer)
Withholding a poor prognosis to protect a patient from distress
Documenting a completed assessment that was not fully performed
Offering false reassurance to reduce a patient's anxiety before infusion

Correct answer: Clearly explaining treatment risks even when the news is difficult

Veracity (truth-telling) requires the nurse to provide honest, accurate information even when that information is difficult to communicate.

Question 47: 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 should equal the long-acting dose given twice daily
The breakthrough dose is typically 10-15% of the total daily opioid dose, given every 1-4 hours as needed (Correct answer)
No breakthrough doses are needed if long-acting opioids are optimized
The breakthrough dose equals the full daily opioid dose divided by 24

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 48: How long should a nurse flush an implanted port access needle with normal saline to confirm patency BEFORE administering a vesicant chemotherapy agent?

5 mL rapidly to clear the needle
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)
1-2 mL to confirm flow

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 49: A nurse wants to find the best evidence for managing chemotherapy-induced nausea. Which resource provides the MOST credible, peer-reviewed clinical practice guidelines?

Pharmaceutical manufacturer prescribing information only
ASCO, ONS, or NCCN clinical practice guidelines (Correct answer)
Patient advocacy websites
General internet search engines

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.

Question 50: 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 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)
The result is not statistically significant because the CI crosses 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 51: After extravasation of doxorubicin, what is the recommended topical treatment to minimize tissue damage?

Apply hyaluronidase topically to the site
Apply warm compress for 20 minutes four times daily
Apply cold compress and administer dexrazoxane IV per protocol (Correct answer)
Inject sodium thiosulfate subcutaneously around the site

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 52: Grade 3-4 immune-related colitis that does not respond to high-dose corticosteroids should be treated with:

Emergency surgical colectomy as the only option
High-dose methotrexate immunosuppression
Infliximab (anti-TNF monoclonal antibody) (Correct answer)
Dose escalation of the checkpoint inhibitor

Correct answer: Infliximab (anti-TNF monoclonal antibody)

Infliximab, an anti-TNF antibody, is the recommended treatment for steroid-refractory immune-related colitis as it effectively suppresses TNF-mediated intestinal inflammation.

Question 53: A patient with lung cancer on opioids develops progressive confusion, hyperreflexia, and seizures. Labs show serum sodium of 118 mEq/L. What is occurring?

Opioid toxicity
Hypercalcemia of malignancy
Tumor lysis syndrome
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 54: A patient on doxorubicin complains of mouth sores and is unable to eat. The nurse grades the mucositis as Grade 3. Which intervention is appropriate?

Apply petroleum jelly to the lips only
Rinse with commercial mouthwash containing alcohol
Initiate parenteral nutrition and notify the provider for dose modification (Correct answer)
Encourage hot liquids to stimulate saliva

Correct answer: Initiate parenteral nutrition and notify the provider for dose modification

Grade 3 mucositis (inability to eat) requires nutritional support and provider notification for possible chemotherapy dose modification.

Question 55: 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?

Discontinue the opioid and switch to NSAIDs
Administer methylnaltrexone (Relistor) to reverse peripheral opioid effects in the GI tract (Correct answer)
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 56: The legal doctrine that holds nurses to the standard of care expected of a reasonably prudent nurse with similar training and experience is the basis for:

Nursing malpractice claims (Correct answer)
Whistleblower protection statutes
Administrative license suspension
Criminal negligence charges

Correct answer: Nursing malpractice claims

Nursing malpractice is evaluated against the standard of care a reasonably prudent nurse would provide under similar circumstances.

Question 57: A patient receiving docetaxel develops periorbital edema and weight gain of 5 lbs in one week. What does the nurse recognize?

Syndrome of inappropriate antidiuretic hormone (SIADH)
Allergic reaction requiring epinephrine
Capillary leak syndrome related to fluid accumulation (Correct answer)
Cardiac tamponade

Correct answer: Capillary leak syndrome related to fluid accumulation

Docetaxel causes fluid retention and capillary leak syndrome manifesting as peripheral edema, pleural effusion, and weight gain.

Question 58: 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
Catheter fracture
Pulmonary embolism
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 59: A patient with multiple myeloma develops confusion, polyuria, constipation, and a serum calcium of 13.5 mg/dL. What is the initial treatment priority?

Initiate bisphosphonate therapy as the first intervention
Begin aggressive IV normal saline hydration to promote calciuresis (Correct answer)
Administer oral calcium supplements to correct the imbalance
Administer loop diuretics without IV fluids

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 60: Which statement best describes the mechanism by which trastuzumab (Herceptin) enhances chemotherapy efficacy in HER2-positive breast cancer?

It inhibits HER2 kinase activity by competing with ATP at the intracellular binding domain
It prevents HER2 dimerization by binding the extracellular domain II, functioning identically to pertuzumab
It binds the extracellular domain IV of HER2, blocking downstream PI3K/AKT and MAPK signaling while recruiting immune effectors via ADCC (Correct answer)
It directly alkylates DNA in HER2-overexpressing cells, acting as a targeted chemotherapy

Correct answer: It binds the extracellular domain IV of HER2, blocking downstream PI3K/AKT and MAPK signaling while recruiting immune effectors via ADCC

Trastuzumab binds HER2 domain IV, inhibiting downstream proliferation signaling and mediating antibody-dependent cellular cytotoxicity (ADCC) against HER2-overexpressing cells.

Question 61: What is the primary nursing goal when managing chemotherapy-induced thrombocytopenia with a platelet count of 15,000/mm³?

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

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

Hemorrhagic cystitis from acrolein metabolite accumulation (Correct answer)
Bladder cancer as a late effect
Renal failure from drug nephrotoxicity
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 63: Which is the MOST appropriate initial nursing intervention for a patient who develops cardiac tamponade from a malignant pericardial effusion?

Position the patient upright, administer IV fluids, and prepare for emergency pericardiocentesis (Correct answer)
Administer IV furosemide to reduce fluid accumulation
Initiate CPR immediately
Place the patient supine and administer nitroglycerin

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 64: A patient undergoing aggressive chemotherapy for leukemia develops hyperkalemia, hyperphosphatemia, hypocalcemia, and elevated uric acid. What syndrome is occurring?

Hypercalcemia of malignancy
Syndrome of inappropriate antidiuretic hormone
Tumor lysis syndrome (Correct answer)
Disseminated intravascular coagulation

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

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

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

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

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 67: A patient with metastatic colorectal cancer is started on bevacizumab (Avastin). Which mechanism explains its anti-tumor activity?

Bevacizumab crosses the cell membrane to inhibit HIF-1α transcription factor, reducing VEGF production
Bevacizumab activates complement-mediated lysis of VEGF-expressing tumor-associated endothelial cells
Bevacizumab binds VEGFR-2 on tumor cells, blocking intracellular tyrosine kinase signaling directly
Bevacizumab binds circulating VEGF-A, preventing it from binding to endothelial VEGF receptors and inhibiting tumor angiogenesis (Correct answer)

Correct answer: Bevacizumab binds circulating VEGF-A, preventing it from binding to endothelial VEGF receptors and inhibiting tumor angiogenesis

Bevacizumab is a monoclonal antibody that sequesters circulating VEGF-A, preventing it from binding endothelial receptors and thereby starving tumors of new blood vessel formation.

Question 68: Before administering chemotherapy through a port-a-cath, the nurse aspirates and gets no blood return. What is the MOST appropriate next step?

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

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 69: Which assessment scale is MOST appropriate for evaluating pain in an oncology patient with moderate cognitive impairment?

PAINAD (Pain Assessment in Advanced Dementia) scale (Correct answer)
Numeric Rating Scale (NRS) 0-10
Visual Analog Scale (VAS)
McGill Pain Questionnaire

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 70: Which nutritional screening tool is MOST commonly recommended for oncology patients to identify malnutrition risk?

Body Mass Index (BMI) measurement alone
Serum albumin level
Patient-Generated Subjective Global Assessment (PG-SGA) (Correct answer)
24-hour dietary recall only

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 71: What is the nurse's primary responsibility when a patient refuses chemotherapy?

Inform the family and proceed with treatment
Try to convince the patient to continue treatment
Respect the patient’s decision and notify the provider (Correct answer)
Schedule the next chemotherapy session anyway

Correct answer: Respect the patient’s decision and notify the provider

Patients have the right to refuse medical treatment, even if it is life-sustaining. The nurse's ethical responsibility is to respect the patient's autonomy and decision, ensuring they are fully informed of the implications. After respecting the patient's choice, the nurse must promptly notify the healthcare provider so that alternative care plans or discussions can be initiated.

Question 72: 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)
Physician presence is required and the nurse cannot witness consent
Written consent obtained within 24 hours of enrollment

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 73: A patient on high-dose ifosfamide becomes acutely confused, agitated, and develops visual hallucinations. What neurotoxic complication is occurring?

Ifosfamide-induced encephalopathy (Correct answer)
Wernicke's encephalopathy
Opioid toxicity
Electrolyte imbalance from vomiting

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 74: 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
Reset the pump alarm and reassess in 30 minutes
Stop the infusion, assess for extravasation, and notify the provider (Correct answer)
Increase the infusion rate to complete the dose on schedule

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 75: 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
Graft-versus-host disease (GVHD) (Correct answer)
Cytomegalovirus colitis
Clostridium difficile infection

Correct answer: Graft-versus-host disease (GVHD)

The triad of fever, diarrhea, and maculopapular skin rash (especially palms/soles) post-transplant is classic for acute graft-versus-host disease.
