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
Using tissue plasminogen activator (tPA) prophylactically after every infusion
Flushing with 10 mL normal saline using a pulsatile push technique after each use (Correct answer)
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 2: 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)
Weight loss of 2 lbs over 3 weeks
ANC of 2,000/mm³ at end of cycle
Mild insomnia reported by the patient

Correct answer: Hemoglobin of 7.5 g/dL with symptoms of dyspnea on exertion

Anemia (Hgb 7.5 g/dL) with symptomatic dyspnea is a directly treatable cause of cancer-related fatigue, warranting evaluation for RBC transfusion or erythropoiesis-stimulating agents.

Question 3: 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 4: 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
Acupuncture and acupressure (Correct answer)
Magnet therapy

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

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

Correct answer: Stop the infusion and notify the provider immediately

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

Question 6: Docetaxel differs from paclitaxel in which clinically important pharmacokinetic characteristic?

Docetaxel is renally eliminated while paclitaxel undergoes biliary excretion
Docetaxel has approximately twice the binding affinity for tubulin and is primarily hepatically metabolized by CYP3A4, requiring dose reduction in hepatic impairment (Correct answer)
Docetaxel requires albumin nanoparticle formulation to achieve therapeutic concentrations
Docetaxel's longer half-life of 72 hours allows once-monthly dosing compared to paclitaxel's weekly schedule

Correct answer: Docetaxel has approximately twice the binding affinity for tubulin and is primarily hepatically metabolized by CYP3A4, requiring dose reduction in hepatic impairment

Docetaxel has higher tubulin binding affinity than paclitaxel and undergoes extensive hepatic metabolism via CYP3A4, necessitating dose reduction when liver function is impaired.

Question 7: After extravasation of doxorubicin, what is the recommended topical treatment to minimize tissue damage?

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

Correct answer: Apply cold compress and administer dexrazoxane IV per protocol

Cold compresses limit drug spread, and dexrazoxane is the FDA-approved antidote for anthracycline extravasation that prevents progressive tissue necrosis.

Question 8: Which pharmacokinetic property of vincristine makes it particularly dangerous if accidentally administered intrathecally?

High lipophilicity causes rapid CNS accumulation and demyelination
Extensive protein binding prevents redistribution away from neural tissue
The drug is irreversibly bound to tubulin in neural cells causing axonal destruction
Lack of CNS metabolism leads to prolonged exposure causing ascending paralysis and death (Correct answer)

Correct answer: Lack of CNS metabolism leads to prolonged exposure causing ascending paralysis and death

Intrathecal vincristine is uniformly fatal; it causes progressive ascending demyelination and paralysis because there is no mechanism for clearance from CSF.

Question 9: 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 10: Which biomarker is most commonly used to predict response to PD-1/PD-L1 checkpoint inhibitors across multiple tumor types?

KRAS mutation status
PD-L1 expression by immunohistochemistry (tumor proportion score) (Correct answer)
HER2 gene amplification
BCR-ABL fusion transcript

Correct answer: PD-L1 expression by immunohistochemistry (tumor proportion score)

PD-L1 expression measured by IHC is an established predictive biomarker for checkpoint inhibitor response, with higher expression generally correlating with greater benefit.

Question 11: Which ethical framework guides a nurse who reasons that withholding the truth about a terminal prognosis causes more harm than good and therefore chooses to disclose it honestly?

Consequentialist (utilitarian) ethics (Correct answer)
Virtue ethics
Principlism
Deontological (duty-based) ethics

Correct answer: Consequentialist (utilitarian) ethics

Consequentialist ethics evaluates the morality of an action based on its outcomes, choosing the action that produces the greatest overall benefit.

Question 12: 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
Ileus/bowel obstruction from vincristine-induced neurotoxicity (Correct answer)
Chemotherapy-induced diarrhea
Bowel perforation

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

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

Correct answer: Use a non-coring Huber needle with strict aseptic technique

A non-coring Huber needle is required to access implanted ports without coring the silicone septum, and strict aseptic technique prevents catheter-related bloodstream infections.

Question 14: Which intervention is MOST effective for managing cancer-related depression in oncology patients?

Combined pharmacotherapy (antidepressants) and psychotherapy (CBT or supportive counseling) (Correct answer)
Increasing physical activity without any pharmacotherapy
Administering corticosteroids to improve mood
Opioid dose reduction

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 15: 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 48 hours with antimicrobial gauze
Every 7 days with transparent semi-permeable membrane dressing (unless soiled) (Correct answer)

Correct answer: Every 7 days with transparent semi-permeable membrane dressing (unless soiled)

Current INS and CDC guidelines recommend transparent dressing changes every 7 days for tunneled CVC exit sites unless the dressing becomes wet, soiled, or loose.

Question 16: 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
Confirm the PICC is rated for power injection and document the maximum pressure and flow rate (Correct answer)
Remove the PICC before the scan to prevent malfunction
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 17: 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?

Graft-versus-host disease (GVHD) (Correct answer)
Chemotherapy-induced mucositis
Clostridium difficile infection
Cytomegalovirus colitis

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.

Question 18: 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 19: The nurse is educating a patient with a tunneled Hickman catheter about home care. Which instruction is MOST important?

Clamp the catheter only during dressing changes
Submerge the catheter in water briefly during bathing
Change the cap and flush the catheter per the prescribed protocol, and report fever above 100.4°F (Correct answer)
Remove the dressing daily to inspect the exit site

Correct answer: Change the cap and flush the catheter per the prescribed protocol, and report fever above 100.4°F

Fever above 100.4°F in a patient with a tunneled catheter is a red flag for catheter-related bloodstream infection requiring immediate reporting.

Question 20: Which situation warrants holding a chemotherapy dose and notifying the physician BEFORE administration?

ANC of 1800 cells/mm³ and platelets of 120,000/mm³
Hemoglobin of 11.2 g/dL in a patient on capecitabine
ANC of 450 cells/mm³ and platelets of 60,000/mm³ (Correct answer)
Mild nausea controlled with ondansetron from the prior cycle

Correct answer: ANC of 450 cells/mm³ and platelets of 60,000/mm³

An ANC below 500 cells/mm³ and platelets below 75,000–100,000/mm³ typically meet hold parameters that require physician reassessment before proceeding.

Question 21: 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?

Catheter tip has migrated into the jugular vein (Correct answer)
Air in the infusion line
Normal catheter sounds during infusion
The patient has developed atrial fibrillation

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

The treatment is experimental and only available in clinical trials
Expert opinion supports this as a preferred option with limited evidence
High-level evidence with uniform consensus that the recommendation is appropriate (Correct answer)
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 23: Which nutritional screening tool is MOST commonly recommended for oncology patients to identify malnutrition risk?

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

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

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

Correct answer: Document the event in the chart, report to the principal investigator immediately, and complete the adverse event report per protocol

Serious adverse events must be documented, immediately reported to the PI, and captured in the adverse event reporting system per the protocol's safety monitoring plan.

Question 25: A patient on ifosfamide therapy reports hematuria and painful urination. Which targeted assessment finding confirms the suspected complication?

Positive urinalysis for leukocyte esterase and nitrites
Urine specific gravity >1.030 with dysuria
Elevated serum creatinine with flank pain
Gross blood in urine with negative urine culture (Correct answer)

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 26: Asparaginase treats acute lymphoblastic leukemia (ALL) by exploiting which metabolic vulnerability of leukemic blasts?

ALL blasts lack asparagine synthetase and cannot produce their own asparagine, making them dependent on circulating asparagine (Correct answer)
ALL blasts have defective purine synthesis and asparaginase blocks the salvage pathway
Leukemic cells overexpress asparaginase receptors, concentrating the drug intracellularly
Leukemic blasts cannot synthesize glutamine and depend entirely on exogenous supply

Correct answer: ALL blasts lack asparagine synthetase and cannot produce their own asparagine, making them dependent on circulating asparagine

Leukemic lymphoblasts have low or absent asparagine synthetase expression, making them unable to synthesize asparagine and thus dependent on serum levels that asparaginase depletes.

Question 27: When administering rituximab, premedication is given to reduce which type of reaction?

Chemotherapy-induced nausea and vomiting (CINV)
Extravasation injury at the IV site
Peripheral neuropathy from the drug
Infusion-related reactions (IRRs) including cytokine release (Correct answer)

Correct answer: Infusion-related reactions (IRRs) including cytokine release

Rituximab frequently causes cytokine release-mediated infusion-related reactions, so acetaminophen, diphenhydramine, and sometimes corticosteroids are given as premedication.

Question 28: Which position should the nurse place a patient in if air embolism is suspected during central line removal?

Right lateral decubitus
Left lateral Trendelenburg (Durant's maneuver) (Correct answer)
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 29: 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 101°F, normal blood pressure, elevated WBC of 12,000/mm³
Temperature of 100.6°F, systolic BP of 85 mmHg despite fluid resuscitation, lactate of 3.2 mmol/L (Correct answer)
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 30: 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 31: 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
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)

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 32: Which regulatory body provides oversight and approval for oncology clinical trials and new drug applications in the United States?

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

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

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

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 34: Which antiemetic class is MOST effective for preventing acute chemotherapy-induced nausea and vomiting (CINV) caused by highly emetogenic regimens?

5-HT3 receptor antagonists (ondansetron) (Correct answer)
Dopamine antagonists (metoclopramide)
Antihistamines (diphenhydramine)
Corticosteroids alone

Correct answer: 5-HT3 receptor antagonists (ondansetron)

5-HT3 receptor antagonists are first-line agents for preventing acute CINV from highly emetogenic chemotherapy regimens.

Question 35: 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?

Low-dose oral or IV opioids to reduce the sensation of breathlessness (Correct answer)
Anxiolytics as first-line therapy
High-flow oxygen regardless of saturation level
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 36: Which personal protective equipment (PPE) component is specifically required when administering aerosolized or nebulized hazardous drugs?

Standard surgical mask
Double nitrile gloves only
N95 respirator or powered air-purifying respirator (PAPR) (Correct answer)
Face shield alone

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 37: Hydroxyurea treats chronic myelogenous leukemia (CML) through inhibition of which enzyme?

Topoisomerase I, preventing relaxation of supercoiled DNA during S phase
Dihydrofolate reductase, depleting thymidylate precursors needed for DNA synthesis
Ribonucleotide reductase, blocking conversion of ribonucleotides to deoxyribonucleotides and halting DNA synthesis (Correct answer)
Thymidine kinase, preventing phosphorylation of thymidine to TMP for DNA synthesis

Correct answer: Ribonucleotide reductase, blocking conversion of ribonucleotides to deoxyribonucleotides and halting DNA synthesis

Hydroxyurea inhibits ribonucleotide reductase, blocking the rate-limiting step in deoxyribonucleotide synthesis and arresting cells in S phase.

Question 38: A patient with a PICC line develops pain, erythema, and a palpable cord along the arm. What complication does the nurse suspect?

Air embolism
Catheter migration
Thrombophlebitis (Correct answer)
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 39: When a patient in a clinical trial asks to withdraw from the study, the nurse's appropriate response is to:

Encourage the patient to reconsider, as withdrawal may harm their treatment outcome
Consult the principal investigator before acknowledging the patient's request
Honor the patient's right to withdraw at any time without penalty and notify the research team (Correct answer)
Inform the patient that withdrawal may not be possible once treatment has begun

Correct answer: Honor the patient's right to withdraw at any time without penalty and notify the research team

The Belmont Report principles and federal regulations guarantee research participants the right to withdraw at any time without loss of benefits.

Question 40: Before starting chemotherapy, which baseline assessment is most critical?

Urinalysis
Electrocardiogram
Complete blood count (CBC) (Correct answer)
Liver function tests

Correct answer: Complete blood count (CBC)

A Complete Blood Count (CBC) is the most critical baseline assessment before chemotherapy because many chemotherapy drugs are myelosuppressive, meaning they can suppress bone marrow function. This assessment provides vital information about the patient's white blood cells, red blood cells, and platelets, which helps determine if the patient can safely receive treatment and guides dose adjustments.

Question 41: 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 a saline enema daily
Administer methylnaltrexone (Relistor) to reverse peripheral opioid effects in the GI tract (Correct answer)
Increase dietary fiber intake to 30g/day

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 42: 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 43: When preparing chemotherapy agents in the pharmacy, which type of biological safety cabinet (BSC) is required?

Class II Type B2 BSC (Correct answer)
Class I BSC
Class II Type A2 BSC
Class III BSC

Correct answer: Class II Type B2 BSC

NIOSH and USP 800 require a Class II Type B2 BSC for hazardous drug compounding because it provides 100% exhaust to the outdoors with no air recirculation.

Question 44: 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)
Document the refusal and take no further action
Consult psychiatry for assessment of decision-making capacity
Override the patient's decision because comfort is the primary goal of hospice

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 45: 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)
Unblind the patient only with physician approval
Withdraw the patient from the trial if they continue to ask
Tell the patient which arm they are in if they sincerely want to know

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 46: 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
No breakthrough doses are needed if long-acting opioids are optimized
The breakthrough dose is typically 10-15% of the total daily opioid dose, given every 1-4 hours as needed (Correct answer)
The breakthrough dose 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 47: A nurse wants to find the best evidence for managing chemotherapy-induced nausea. Which resource provides the MOST credible, peer-reviewed clinical practice guidelines?

ASCO, ONS, or NCCN clinical practice guidelines (Correct answer)
Pharmaceutical manufacturer prescribing information only
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 48: 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 PI can waive the exclusion criterion for a qualified patient
The patient cannot be enrolled; eligibility criteria are legally binding safety parameters that cannot be waived (Correct answer)
The patient may enroll with a signed consent acknowledging the deviation

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 49: 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 50: Under the Americans with Disabilities Act (ADA), an oncology nurse with a disability who requires a reasonable accommodation to safely perform essential job functions should:

Self-accommodate without notifying the employer
Accept reassignment to a non-clinical role without discussion
Conceal the disability to avoid discrimination in scheduling
Formally request the accommodation through the facility's HR department (Correct answer)

Correct answer: Formally request the accommodation through the facility's HR department

The ADA requires employees to formally request reasonable accommodations through appropriate institutional channels to trigger employer obligations.

Question 51: A patient refuses a recommended chemotherapy regimen after being fully informed of the risks and benefits. What is the nurse's ethical obligation?

Notify the ethics committee to override the patient's decision
Document the refusal and respect the patient's autonomous decision (Correct answer)
Administer the treatment anyway to preserve life
Discharge the patient for non-compliance

Correct answer: Document the refusal and respect the patient's autonomous decision

Respecting patient autonomy requires honoring informed refusal, even if the nurse disagrees with the decision.

Question 52: The oncology nurse is reviewing a study that reports a hazard ratio (HR) of 0.65 with a 95% CI of 0.50-0.85 for a new drug versus placebo. What does this mean?

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

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

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

Question 53: Pemetrexed (Alimta) requires vitamin B12 and folic acid supplementation. Which adverse effects are being prevented by this supplementation?

Renal tubular acidosis from pemetrexed crystal precipitation in acid urine requiring alkalinization
Neutropenia, mucositis, and fatigue caused by multi-target antifolate activity in normal proliferating tissues (Correct answer)
Neurotoxicity from elevated homocysteine levels generated by inhibition of methionine synthase
Pemetrexed-induced megaloblastic anemia due to direct folate depletion in erythroid precursors

Correct answer: Neutropenia, mucositis, and fatigue caused by multi-target antifolate activity in normal proliferating tissues

Pemetrexed inhibits multiple folate-dependent enzymes (TYMS, DHFR, GARFT); B12 and folic acid supplementation reduces hematologic and mucosal toxicities in normal tissues without protecting tumor cells.

Question 54: 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?

Only the patient should press the PCA button; caregiver-controlled dosing increases overdose risk (Correct answer)
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

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 55: When obtaining informed consent for chemotherapy, which element is ESSENTIAL for the consent to be legally and ethically valid?

The oncologist must administer consent without nursing involvement
The patient must demonstrate decision-making capacity at the time of consent (Correct answer)
Consent must be obtained at least 48 hours before treatment
The patient must sign the form in the presence of two witnesses

Correct answer: The patient must demonstrate decision-making capacity at the time of consent

Valid informed consent requires that the patient possess decision-making capacity, receive adequate information, and consent voluntarily.

Question 56: A patient receiving high-dose cyclophosphamide reports severe bladder pain, urinary frequency, and grossly bloody urine. What complication has occurred?

Urinary tract infection
Bladder cancer as a late effect
Renal failure from drug nephrotoxicity
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 57: Which intervention is the MOST critical in preventing tumor lysis syndrome in high-risk patients?

Restricting dietary potassium
Administering calcium gluconate prophylactically
Placing the patient on continuous telemetry only
Aggressive IV hydration and allopurinol or rasburicase administration before chemotherapy (Correct answer)

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 58: 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?

Dexamethasone at standard doses
Megestrol acetate (Megace) (Correct answer)
Ondansetron
Metoclopramide

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 59: 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?

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

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 60: 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
Increase the opioid dose or switch to a stronger opioid for uncontrolled moderate-to-severe pain (Correct answer)
Switch to non-pharmacologic methods only
Add a non-opioid adjuvant and remove the opioid

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 61: Which study design provides the HIGHEST level of evidence for evaluating the effectiveness of a new chemotherapy regimen?

Case series
Randomized controlled trial (RCT) (Correct answer)
Expert consensus guidelines
Retrospective cohort study

Correct answer: Randomized controlled trial (RCT)

The randomized controlled trial is the gold standard study design for establishing causal efficacy by minimizing bias through randomization and controlled comparison.

Question 62: Which element is REQUIRED for a patient to provide valid informed consent for clinical trial participation?

Voluntary participation, disclosure of all risks and benefits, and patient comprehension (Correct answer)
Written consent obtained within 24 hours of enrollment
Physician presence is required and the nurse cannot witness consent
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 63: 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?

Increase the infusion rate to complete the dose on schedule
Stop the infusion, assess for extravasation, and notify the provider (Correct answer)
Apply a warm compress and continue monitoring
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 64: A nurse administers rasburicase to a patient for tumor lysis syndrome prophylaxis. Which laboratory precaution is ESSENTIAL?

Check BUN and creatinine before and after each dose
Monitor potassium levels every 2 hours post-administration
Draw uric acid samples in pre-chilled tubes and transport on ice immediately (Correct answer)
Monitor blood glucose levels for hypoglycemia

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 65: 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)
Slow infusion rate over 60 minutes
Young age and good hydration status
Use of a large-bore peripheral IV catheter

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 66: Which type of IV access is preferred for vesicant chemotherapy drugs?

Peripheral short catheter
Butterfly needle
Midline catheter
Central venous catheter (Correct answer)

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

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

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

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

Question 68: Which assessment scale is MOST appropriate for evaluating pain in an oncology patient with moderate cognitive impairment?

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

Correct answer: PAINAD (Pain Assessment in Advanced Dementia) scale

The PAINAD scale assesses pain through behavioral indicators (breathing, vocalization, facial expression, body language, consolability) in patients who cannot self-report reliably.

Question 69: 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 compare the new drug with the current standard of care
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

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

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

Correct answer: Vincristine

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

Question 71: 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)
Reposition the patient and try aspiration again, then administer if still no return
Administer the chemotherapy slowly and monitor the site

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 72: 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 73: A patient with advanced cancer asks the nurse not to tell her family about her prognosis. A family member calls and demands the information. The nurse should:

Disclose only if the family member is the healthcare proxy
Honor the patient's confidentiality and not disclose without consent (Correct answer)
Share the information to relieve family distress
Refer the family member to the social worker and say nothing

Correct answer: Honor the patient's confidentiality and not disclose without consent

HIPAA and ethical principles of confidentiality protect patient information from disclosure without explicit patient consent.

Question 74: Moderate to severe immune-related adverse events (irAEs) from checkpoint inhibitors are primarily managed with:

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

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 75: What is the nurse's FIRST action when a patient on chemotherapy develops signs of anaphylaxis (urticaria, bronchospasm, hypotension)?

Administer corticosteroids IV and observe for 15 minutes
Slow the infusion rate and administer diphenhydramine
Document the reaction and notify the provider after stabilizing the patient
Stop the infusion immediately, call for help, and prepare epinephrine (Correct answer)

Correct answer: Stop the infusion immediately, call for help, and prepare epinephrine

Anaphylaxis is a life-threatening emergency requiring immediate infusion cessation, activation of emergency response, and administration of epinephrine.
