AOCNP Oncology Nurse Practitioner Certification Exam — Questions and Answers

Question 1: Which laboratory finding is NOT part of the classic tumor lysis syndrome (TLS) triad?

Hypocalcemia
Hypernatremia (Correct answer)
Hyperphosphatemia
Hyperkalemia

Correct answer: Hypernatremia

TLS is characterized by hyperkalemia, hyperphosphatemia, hyperuricemia, and secondary hypocalcemia — hypernatremia is not a feature.

Question 2: Radiation-induced secondary malignancy risk is greatest for which patient population?

Patients receiving palliative radiation only
Adults over 70 years treated for prostate cancer
Children and young adults treated with radiation at a young age (Correct answer)
Patients with brain metastases

Correct answer: Children and young adults treated with radiation at a young age

Younger patients have greater remaining lifespan for secondary cancers to develop, and growing tissues are more radiosensitive, making pediatric and young adult survivors highest risk.

Question 3: The dose-limiting toxicity of vincristine is:

Cardiotoxicity
Nephrotoxicity
Myelosuppression
Peripheral neurotoxicity (Correct answer)

Correct answer: Peripheral neurotoxicity

Vincristine causes progressive sensory and motor peripheral neuropathy by binding tubulin and disrupting axonal transport in nerve cells.

Question 4: PARP inhibitors such as olaparib are most effective in patients with which molecular feature?

MSI-high status
High tumor mutational burden (TMB-H)
EGFR exon 19 deletion
BRCA1/2 or other homologous recombination repair (HRR) deficiency (Correct answer)

Correct answer: BRCA1/2 or other homologous recombination repair (HRR) deficiency

PARP inhibitors exploit synthetic lethality in tumors with HRR deficiency, most commonly BRCA1/2 mutations. When BRCA-mutated cells cannot repair double-strand breaks via HRR, PARP inhibition prevents base excision repair, leading to catastrophic DNA damage and cell death.

Question 5: Which modifiable risk factor has the strongest evidence for reducing colorectal cancer incidence?

Increasing dietary fiber intake
Taking daily vitamin D supplements
Regular physical activity and maintaining healthy weight (Correct answer)
Avoiding red meat entirely

Correct answer: Regular physical activity and maintaining healthy weight

Regular physical activity and maintaining a healthy body weight have the strongest evidence for reducing colorectal cancer risk among modifiable lifestyle factors.

Question 6: A patient with colorectal cancer is found to have a RAS mutation. What is the implication for treatment?

Eligible for cetuximab therapy
Requires immediate surgical resection
Not eligible for anti-EGFR therapy (Correct answer)
Indicates sensitivity to bevacizumab

Correct answer: Not eligible for anti-EGFR therapy

RAS mutations (KRAS or NRAS) predict resistance to anti-EGFR antibodies such as cetuximab and panitumumab.

Question 7: What is the primary advantage of proton beam therapy over conventional photon (X-ray) radiation?

Superior immunostimulatory effect
Faster treatment time per session
Lower cost and wider availability
Bragg peak allows dose concentration at the tumor with minimal exit dose (Correct answer)

Correct answer: Bragg peak allows dose concentration at the tumor with minimal exit dose

Protons deposit maximum energy at the Bragg peak, a sharp dose drop-off at a specific depth, with minimal dose beyond the target. This physical property significantly reduces radiation dose to normal tissues beyond the tumor, decreasing toxicity particularly for pediatric tumors and tumors near critical structures.

Question 8: A patient receiving FOLFOX chemotherapy develops grade 3 peripheral neuropathy. What is the most appropriate management?

Dose reduce oxaliplatin by 25%
Continue FOLFOX at full dose
Discontinue oxaliplatin permanently (Correct answer)
Switch to FOLFIRI

Correct answer: Discontinue oxaliplatin permanently

Grade 3 peripheral neuropathy from oxaliplatin warrants permanent discontinuation of oxaliplatin to prevent irreversible nerve damage.

Question 9: A patient receiving high-dose methotrexate suddenly develops fever, rigors, and hypotension. Which oncologic emergency is most likely?

Disseminated intravascular coagulation
Cardiac tamponade
Septic shock (Correct answer)
Anaphylaxis

Correct answer: Septic shock

Febrile neutropenia with hemodynamic compromise meets criteria for septic shock and requires immediate broad-spectrum antibiotics and fluid resuscitation.

Question 10: Lynch syndrome increases lifetime risk of which cancer most significantly?

Prostate cancer
Colorectal cancer (Correct answer)
Breast cancer
Lung cancer

Correct answer: Colorectal cancer

Lynch syndrome (caused by MLH1, MSH2, MSH6, PMS2, EPCAM mutations) confers a 40–80% lifetime risk of colorectal cancer and 15–60% for endometrial cancer.

Question 11: The Data Safety Monitoring Board (DSMB) in a clinical trial has authority to:

Change primary endpoints after enrollment begins
Enroll additional patients beyond the planned sample size without sponsor approval
Recommend early trial termination for benefit, harm, or futility based on interim analyses (Correct answer)
Unblind individual patients to their treatment allocation

Correct answer: Recommend early trial termination for benefit, harm, or futility based on interim analyses

The DSMB (or DSMB/IDMC) is an independent committee that reviews unblinded accumulating data at pre-specified interim analyses. It can recommend early stopping for overwhelming efficacy, unexpected harm, or futility (low probability of showing benefit if continued), protecting trial integrity and participant safety.

Question 12: A patient with cancer-related dyspnea refractory to oxygen is best treated with:

High-dose benzodiazepines alone
Low-dose opioids (Correct answer)
Inhaled beta-agonists
Nebulized furosemide

Correct answer: Low-dose opioids

Low-dose opioids are the most evidence-based pharmacological treatment for refractory dyspnea in cancer patients.

Question 13: A patient develops sudden-onset dyspnea, muffled heart sounds, hypotension, and jugular venous distension. Which emergency is this?

Tension pneumothorax
Cardiac tamponade (Correct answer)
Pulmonary embolism
Acute heart failure

Correct answer: Cardiac tamponade

Beck's triad of hypotension, muffled heart sounds, and jugular venous distension is the hallmark of cardiac tamponade requiring urgent pericardiocentesis.

Question 14: Which biologic agent works by depleting CD20-positive B cells and is used in certain lymphomas?

Cetuximab
Ramucirumab
Denosumab
Rituximab (Correct answer)

Correct answer: Rituximab

Rituximab is a chimeric anti-CD20 monoclonal antibody that depletes CD20-expressing B cells through ADCC, CDC, and direct apoptosis induction.

Question 15: The ONCP/NP monitoring for immune-related colitis from checkpoint inhibitors should include which key assessment?

Complete blood count and differential
Thyroid function tests only
Serum creatinine and BUN levels only
Stool frequency, consistency, presence of blood, and abdominal examination (Correct answer)

Correct answer: Stool frequency, consistency, presence of blood, and abdominal examination

Immune-related colitis typically presents as diarrhea (>4 stools/day above baseline), abdominal pain, or hematochezia. Systematic assessment of stool frequency, blood/mucus, abdominal cramping, and hydration status guides grading and management decisions for irAE colitis.

Question 16: A patient with advanced lung cancer reports severe dyspnea at rest despite supplemental oxygen. Which intervention has the strongest evidence for relieving refractory dyspnea in this setting?

Nebulized furosemide
Anxiolytics alone without opioids
Low-dose systemic opioids (Correct answer)
Increase inspired oxygen concentration to 100%

Correct answer: Low-dose systemic opioids

Low-dose systemic opioids (e.g., oral morphine) are the most evidence-based pharmacologic intervention for refractory dyspnea in advanced cancer.

Question 17: An AOCNP is managing a patient on tamoxifen who is also prescribed paroxetine for depression. What is the primary concern?

Paroxetine inhibits CYP2D6, reducing conversion of tamoxifen to its active metabolite endoxifen (Correct answer)
There is no clinically significant interaction between these agents
Paroxetine increases tamoxifen levels causing toxicity
Paroxetine accelerates tamoxifen metabolism leading to subtherapeutic levels

Correct answer: Paroxetine inhibits CYP2D6, reducing conversion of tamoxifen to its active metabolite endoxifen

Paroxetine is a potent CYP2D6 inhibitor that significantly reduces conversion of tamoxifen to endoxifen, potentially reducing efficacy of hormonal therapy.

Question 18: "I don't think my husband cares about me anymore," an ovarian cancer patient confides to the nurse. When the husband was present, he once told the nurse, "He rarely visits me. I just can't stand to see my wife so sick. I never know what to say to her." In this case, the following nursing diagnostic is appropriate:

Compromised family coping related to disruption in lifestyle and role changes
Impaired home maintenance related to perceived role changes
Interrupted family processes related to the effect of illness on family members (Correct answer)
Risk for caregiver role strain related to burdens of caregiving responsibilities

Correct answer: Interrupted family processes related to the effect of illness on family members

The results show that this diagnosis is most suitable because the patient's cancer diagnosis has distinct effects on the patient's family members.

Question 19: Aromatase inhibitor (AI)-induced arthralgias affect a significant percentage of breast cancer survivors. Which intervention has the strongest evidence for relieving AI-associated musculoskeletal symptoms?

Opioid analgesics scheduled around the clock
Routine NSAIDs scheduled daily
Aerobic and resistance exercise programs (Correct answer)
Switching to a different aromatase inhibitor as the first intervention

Correct answer: Aerobic and resistance exercise programs

Exercise interventions, both aerobic and resistance training, have the strongest evidence base for reducing AI-associated arthralgia severity and improving functional status in breast cancer survivors. Physical therapy and acupuncture also have supporting evidence. Vitamin D optimization is also recommended.

Question 20: A patient is newly diagnosed with diffuse large B-cell lymphoma (DLBCL). Which staging system is most appropriate for this hematologic malignancy?

TNM (tumor-node-metastasis) staging
Dukes classification
Lugano classification (modified Ann Arbor staging) (Correct answer)
FIGO staging

Correct answer: Lugano classification (modified Ann Arbor staging)

The Lugano classification, a refinement of the Ann Arbor staging system, is used for lymphomas including DLBCL. It uses Stages I–IV based on nodal and extranodal involvement and incorporates PET-CT findings. TNM is used for solid tumors. FIGO is for gynecologic cancers. Dukes classification is an older system for colorectal cancer.

Question 21: Which omega-3 fatty acid supplement has the most evidence supporting its use in cancer patients for attenuating weight loss and improving outcomes during chemotherapy?

Flaxseed oil (ALA)
Evening primrose oil (GLA)
EPA (eicosapentaenoic acid) from fish oil (Correct answer)
Conjugated linoleic acid (CLA)

Correct answer: EPA (eicosapentaenoic acid) from fish oil

Eicosapentaenoic acid (EPA), a long-chain omega-3 fatty acid found in fish oil, has the most evidence in oncology nutrition for its anti-inflammatory properties and potential to attenuate cancer cachexia, particularly in pancreatic and upper GI cancers. Multiple trials have examined EPA supplementation for preservation of lean body mass. Evening primrose oil, CLA, and flaxseed-derived ALA (which must be converted to EPA/DHA with limited efficiency) have significantly less evidence in this context.

Question 22: In brachytherapy for cervical cancer, the point 'Point A' is used to prescribe dose. Where is Point A located?

2 cm superior to the cervical os and 2 cm lateral to the uterine canal (Correct answer)
At the bladder neck, 2 cm anterior to the cervix
At the intersection of the uterosacral ligaments
2 cm lateral and 2 cm superior to the external cervical os

Correct answer: 2 cm superior to the cervical os and 2 cm lateral to the uterine canal

Point A is defined as 2 cm superior to the cervical os (or vaginal fornix) and 2 cm lateral to the uterine canal, representing the region of the parametria and paracervical triangle.

Question 23: A patient receiving palliative radiation for painful bone metastases asks when to expect pain relief. The nurse practitioner should counsel that onset of analgesic effect typically occurs:

Within 1–4 weeks after the start of treatment (Correct answer)
Within 2–4 hours of the first fraction
Only after completing the full fractionated course (6–10 weeks)
Pain relief from radiation is unpredictable and rarely occurs

Correct answer: Within 1–4 weeks after the start of treatment

Palliative radiotherapy for bone pain typically produces a response within 1–4 weeks; partial or complete pain relief is achieved in approximately 60–70% of patients.

Question 24: A patient with newly diagnosed acute myeloid leukemia (AML) undergoes induction chemotherapy. On day 15 the bone marrow biopsy shows <5% blasts. This finding indicates:

Partial remission requiring immediate re-induction chemotherapy
Complete remission (CR), and consolidation therapy planning should begin (Correct answer)
Refractory disease requiring allogeneic transplant evaluation immediately
Minimal residual disease positivity mandating maintenance therapy

Correct answer: Complete remission (CR), and consolidation therapy planning should begin

Complete remission in AML is defined as bone marrow blasts <5%, with recovery of peripheral blood counts; this triggers consolidation therapy planning.

Question 25: According to established oncology psychosocial guidelines, which population of cancer patients has the highest documented prevalence of clinically significant depressive disorders?

Patients with pancreatic cancer (Correct answer)
Patients with early-stage localized prostate cancer undergoing active surveillance
Long-term survivors of Hodgkin lymphoma
Patients completing radiation therapy for breast cancer

Correct answer: Patients with pancreatic cancer

Pancreatic cancer is consistently associated with the highest prevalence of depression among all cancer types, with rates reaching 33–50% at diagnosis. Proposed mechanisms include direct neurobiological effects of the tumor, paraneoplastic inflammation, early symptom burden, and poor prognosis. This is clinically important because depression in pancreatic cancer can precede diagnosis by months and is often underrecognized. The other groups have notable but lower rates of clinical depression.

Question 26: VEGF inhibitor bevacizumab carries which unique risk compared to cytotoxic chemotherapy?

Mucositis
Febrile neutropenia
Alopecia
Arterial thromboembolic events, wound healing impairment, and GI perforation (Correct answer)

Correct answer: Arterial thromboembolic events, wound healing impairment, and GI perforation

Anti-VEGF therapy impairs angiogenesis needed for wound healing and vascular integrity, increasing risks of arterial thromboembolism, delayed healing, and GI perforation.

Question 27: Which scale is most widely validated for assessing pain intensity in cognitively intact cancer patients?

FLACC scale
CPOT scale
Numeric Rating Scale (NRS 0–10) (Correct answer)
Wong-Baker FACES scale

Correct answer: Numeric Rating Scale (NRS 0–10)

The 0–10 Numeric Rating Scale is the most widely validated and recommended self-report pain intensity tool for cognitively intact adults.

Question 28: Dense breast tissue on mammography increases breast cancer risk and also:

Reduces mammographic sensitivity, potentially requiring supplemental MRI or ultrasound (Correct answer)
Only affects risk in postmenopausal women
Increases sensitivity of mammography
Is not clinically relevant to screening protocols

Correct answer: Reduces mammographic sensitivity, potentially requiring supplemental MRI or ultrasound

Dense fibroglandular tissue masks lesions on mammography (masking effect) and is also an independent risk factor, prompting many states to mandate notification and offer supplemental screening.

Question 29: A patient with metastatic lung cancer has previously completed a POLST (Physician Orders for Life-Sustaining Treatment) form indicating DNR/DNI status. During a hospitalization, the patient's adult daughter insists the team 'do everything possible.' What is the oncology NP's most appropriate action?

Honor the patient's documented POLST, which reflects the patient's own autonomous choices (Correct answer)
Suspend the POLST and initiate a family meeting before providing any care
Consult the ethics committee before providing any care to the patient
Defer to the family's wishes since the daughter is next of kin

Correct answer: Honor the patient's documented POLST, which reflects the patient's own autonomous choices

A POLST is a legally recognized medical order reflecting the patient's autonomous wishes regarding life-sustaining treatment. It supersedes family preferences when the patient lacks current decision-making capacity and previously had capacity when completing the form. The patient's documented autonomous choice must be respected. Family members do not override a valid POLST. Ethics consultation can be considered for ongoing family conflict but is not required before honoring the existing legal order.

Question 30: A nurse practitioner is counseling a patient starting erlotinib for EGFR-mutant NSCLC about the most common side effect. Which should be emphasized?

Acneiform rash and diarrhea (Correct answer)
Peripheral neuropathy and alopecia
Myelosuppression and febrile neutropenia
Cardiotoxicity and QT prolongation

Correct answer: Acneiform rash and diarrhea

Acneiform rash and diarrhea are the most common side effects of EGFR tyrosine kinase inhibitors such as erlotinib.

Question 31: Which laxative regimen should ALWAYS accompany opioid therapy to prevent constipation?

High-fiber diet alone
Osmotic laxatives only as needed
A stimulant laxative such as senna (Correct answer)
Bulk-forming agents such as psyllium

Correct answer: A stimulant laxative such as senna

A stimulant laxative (senna or bisacodyl) should be initiated prophylactically with opioids because tolerance to constipation, unlike other opioid side effects, does not develop.

Question 32: Which imaging finding on MRI spine best confirms malignant spinal cord compression requiring urgent treatment?

Paraspinal muscle edema only
Disc degeneration with osteophytes
Vertebral body sclerosis without cord contact
Epidural tumor impinging on the thecal sac (Correct answer)

Correct answer: Epidural tumor impinging on the thecal sac

Epidural tumor directly impinging on the thecal sac confirms cord compression and necessitates urgent corticosteroids and radiation or surgery.

Question 33: A patient with multiple myeloma presents with severe back pain, lower extremity weakness, and urinary retention. Which oncologic emergency does this presentation suggest?

Tumor lysis syndrome
Superior vena cava syndrome
Hypercalcemia of malignancy
Spinal cord compression (Correct answer)

Correct answer: Spinal cord compression

Spinal cord compression presents with back pain, motor weakness, and autonomic dysfunction such as urinary retention or incontinence.

Question 34: The ONCO NP conducting research must obtain IRB approval before initiating a study because the IRB serves which primary function?

Approving the budget and funding for the research
Certifying the scientific merit of the research hypothesis
Recruiting patients to meet enrollment targets
Protecting the rights, safety, and welfare of human research participants (Correct answer)

Correct answer: Protecting the rights, safety, and welfare of human research participants

Institutional Review Boards (IRBs) operate under the Belmont Report principles (respect for persons, beneficence, justice) and federal regulations (45 CFR 46, 21 CFR 56) to review and approve research protocols involving human subjects. Their primary mandate is protecting participants from undue risk, coercion, and violations of privacy/autonomy.

Question 35: When interpreting a pathology report, a tumor is described as 'poorly differentiated.' What does this histologic grade indicate about the tumor's behavior?

The tumor closely resembles normal tissue and likely grows slowly
The tumor shows moderate resemblance to normal tissue
The tumor bears little resemblance to normal tissue and is likely more aggressive (Correct answer)
The tumor has not yet invaded beyond the basement membrane

Correct answer: The tumor bears little resemblance to normal tissue and is likely more aggressive

Histologic grade reflects how closely tumor cells resemble normal cells. Poorly differentiated (high-grade, Grade 3) tumors have lost most normal cell characteristics, indicating more aggressive behavior and typically worse prognosis. Well-differentiated tumors (Grade 1) closely resemble normal tissue. Moderately differentiated = Grade 2. Invasion beyond the basement membrane relates to staging, not grading.

Question 36: A patient receiving cisplatin-based chemotherapy develops sudden hemoptysis, chest pain, and dyspnea. CT shows a filling defect in the pulmonary artery. Which risk factor most predisposed this patient?

Thrombocytopenia from chemotherapy
Radiation-induced pericarditis
Cisplatin-induced hypercoagulable state (Correct answer)
Tumor lysis syndrome

Correct answer: Cisplatin-induced hypercoagulable state

Cisplatin is associated with endothelial damage and a hypercoagulable state, significantly increasing the risk of venous thromboembolism including pulmonary embolism.

Question 37: Palliative sedation is ethically appropriate when:

Refractory symptoms cannot be controlled by other means near end of life (Correct answer)
The patient requests euthanasia
Pain scores exceed 7 at any point in treatment
Family members request it without patient consent

Correct answer: Refractory symptoms cannot be controlled by other means near end of life

Palliative sedation is ethically justified only for refractory, intractable symptoms at the end of life when all other interventions have failed.

Question 38: Which medication is first-line for neuropathic pain in cancer patients?

Methadone as monotherapy
Gabapentin or pregabalin (Correct answer)
Codeine
Ibuprofen

Correct answer: Gabapentin or pregabalin

Gabapentinoids (gabapentin or pregabalin) are first-line adjuvant analgesics for neuropathic pain in cancer patients.

Question 39: Methylnaltrexone (Relistor) treats opioid-induced constipation by:

Inhibiting serotonin in the gut
Stimulating intestinal smooth muscle directly
Increasing intestinal secretions
Blocking peripheral mu-opioid receptors in the GI tract without reversing central analgesia (Correct answer)

Correct answer: Blocking peripheral mu-opioid receptors in the GI tract without reversing central analgesia

Methylnaltrexone is a peripherally acting mu-opioid receptor antagonist that reverses GI opioid effects without crossing the blood-brain barrier.

Question 40: A patient presents with Lynch syndrome. Which cancer screening is NOT part of the standard surveillance protocol?

Annual endometrial biopsy for women
Annual colonoscopy
Routine lung CT scan (Correct answer)
Annual urinalysis for urothelial cancer surveillance

Correct answer: Routine lung CT scan

Lynch syndrome surveillance does not include routine lung CT; it focuses on colorectal, endometrial, urinary tract, and other Lynch-associated cancers.

Question 41: When counseling a patient about prostate cancer screening with PSA, which shared decision-making point is MOST evidence-based?

PSA screening benefit is greatest for men over age 70
PSA screening clearly reduces prostate cancer mortality with minimal harms
PSA screening may reduce prostate cancer mortality but carries risks of overdiagnosis and overtreatment (Correct answer)
PSA screening is not recommended for any man regardless of risk

Correct answer: PSA screening may reduce prostate cancer mortality but carries risks of overdiagnosis and overtreatment

Evidence shows PSA screening may modestly reduce prostate cancer mortality but substantially increases overdiagnosis and overtreatment; individualized shared decision-making is essential.

Question 42: Which malignancy is MOST commonly associated with malignant pericardial effusion and cardiac tamponade?

Lung and breast cancer (Correct answer)
Colorectal carcinoma
Cervical cancer
Hepatocellular carcinoma

Correct answer: Lung and breast cancer

Lung cancer and breast cancer account for the majority of malignant pericardial effusions due to their high incidence and tendency for mediastinal and pericardial involvement.

Question 43: Which prognostic tool is validated to estimate survival in weeks to months for palliative care patients?

Karnofsky score alone
MASCC score
Palliative Performance Scale (PPS) (Correct answer)
ECOG Performance Status alone

Correct answer: Palliative Performance Scale (PPS)

The Palliative Performance Scale integrates ambulation, activity, self-care, oral intake, and consciousness to provide a validated survival estimate.

Question 44: What is the preferred initial antibiotic for low-risk febrile neutropenia being managed outpatient?

IV vancomycin
IV meropenem
Ciprofloxacin plus amoxicillin-clavulanate (Correct answer)
Oral metronidazole

Correct answer: Ciprofloxacin plus amoxicillin-clavulanate

Oral ciprofloxacin combined with amoxicillin-clavulanate is the IDSA-recommended outpatient regimen for low-risk febrile neutropenia.

Question 45: Which lab value change in the immediate postoperative period after major cancer surgery most warrants notification of the surgical team?

Serum lactate >2 mmol/L with tachycardia and hypotension (Correct answer)
Hemoglobin decrease of 0.5 g/dL from preoperative baseline
WBC increase from 7,000 to 9,000 post-surgery
Mild hyperglycemia (140–160 mg/dL) in a diabetic patient

Correct answer: Serum lactate >2 mmol/L with tachycardia and hypotension

Elevated serum lactate (>2 mmol/L) combined with tachycardia and hypotension in the postoperative period suggests tissue hypoperfusion and may indicate hemorrhage, sepsis, anastomotic leak, or other major complications requiring immediate intervention. This constellation represents a surgical emergency.

Question 46: When educating a patient on granulocyte colony-stimulating factor (G-CSF) self-injection, which statement by the patient indicates understanding?

'I should skip doses if my white blood cell count is normal.'
'I should start the injection 24 hours after chemotherapy and not inject in bruised areas.' (Correct answer)
'I should inject it the same day I receive chemotherapy.'
'I should store the medication at room temperature indefinitely.'

Correct answer: 'I should start the injection 24 hours after chemotherapy and not inject in bruised areas.'

G-CSF should be started 24–72 hours after chemotherapy completion, not on the same day, and injected into unaffected skin sites.

Question 47: Which non-pharmacological intervention has the strongest evidence for reducing cancer-related fatigue?

Vitamin C supplementation
Prolonged bed rest
Aerobic exercise (Correct answer)
Methylphenidate alone

Correct answer: Aerobic exercise

Aerobic exercise is the most evidence-based intervention for cancer-related fatigue, improving both physical and psychological components.

Question 48: Stereotactic body radiation therapy (SBRT) for a peripheral lung tumor uses a biologically effective dose (BED) of 100 Gy or more. This high BED is thought to achieve tumor control partly through which mechanism beyond direct DNA damage?

Upregulation of tumor suppressor genes
Enhanced repair of sublethal damage in tumor cells
Ablation of tumor vasculature causing indirect tumor cell death (Correct answer)
Increased tumor oxygenation from vascular normalization

Correct answer: Ablation of tumor vasculature causing indirect tumor cell death

High-dose-per-fraction SBRT is believed to destroy tumor vasculature, causing indirect tumor cell death through ischemia in addition to direct cytotoxicity.

Question 49: Which first-line intervention is indicated for hypercalcemia of malignancy with corrected serum calcium > 14 mg/dL?

Oral calcitonin
Furosemide alone
IV bisphosphonate alone
Aggressive IV normal saline hydration followed by bisphosphonate (Correct answer)

Correct answer: Aggressive IV normal saline hydration followed by bisphosphonate

Aggressive IV normal saline rehydration is the immediate priority, followed by a bisphosphonate such as zoledronic acid to lower calcium.

Question 50: When counseling a premenopausal woman with hormone receptor-positive breast cancer about fertility preservation, which option is safest prior to chemotherapy?

Immediate chemotherapy initiation to avoid tumor progression
Embryo or oocyte cryopreservation before chemotherapy (Correct answer)
GnRH agonist therapy started concurrently with chemotherapy
Oral contraceptive pills to suppress ovarian function

Correct answer: Embryo or oocyte cryopreservation before chemotherapy

Embryo or oocyte cryopreservation before chemotherapy is the most established and effective fertility preservation method for premenopausal women.

Question 51: A patient with small cell lung cancer presents with hyponatremia (Na 118 mEq/L), concentrated urine, and euvolemia. Which oncologic emergency is most likely?

Tumor lysis syndrome
Syndrome of inappropriate antidiuretic hormone (SIADH) (Correct answer)
Adrenal crisis
Cerebral salt wasting

Correct answer: Syndrome of inappropriate antidiuretic hormone (SIADH)

SIADH is a common paraneoplastic complication of small cell lung cancer presenting with euvolemic hyponatremia and urine osmolality inappropriately elevated relative to serum.

Question 52: G-CSF (filgrastim) is primarily used in oncology to:

Treat anemia in cancer patients
Block chemotherapy-induced alopecia
Prevent thrombocytopenia after chemotherapy
Stimulate neutrophil production to reduce the duration of neutropenia (Correct answer)

Correct answer: Stimulate neutrophil production to reduce the duration of neutropenia

Granulocyte colony-stimulating factor stimulates bone marrow to produce and release neutrophils, shortening neutropenia duration and lowering febrile neutropenia risk.

Question 53: Which of the following is the most accurate description of a complete cytogenetic response (CCyR) to imatinib therapy in CML?

No Philadelphia chromosome-positive cells detected in cytogenetic analysis (0% Ph+ metaphases) (Correct answer)
White blood cell count normalized to within normal limits
BCR-ABL transcript undetectable by PCR
Fewer than 35% Philadelphia chromosome-positive metaphases

Correct answer: No Philadelphia chromosome-positive cells detected in cytogenetic analysis (0% Ph+ metaphases)

Complete cytogenetic response (CCyR) is defined as 0% Philadelphia chromosome-positive metaphases on conventional cytogenetic analysis of bone marrow.

Question 54: Which tool is specifically validated for assessing symptom burden in patients with advanced cancer across multiple symptom domains?

Numeric Rating Scale (NRS)
Edmonton Symptom Assessment System (ESAS) (Correct answer)
Karnofsky Performance Status (KPS)
Palliative Performance Scale (PPS)

Correct answer: Edmonton Symptom Assessment System (ESAS)

The Edmonton Symptom Assessment System (ESAS) is a validated, multidimensional tool that rates nine common symptoms (pain, fatigue, nausea, depression, anxiety, drowsiness, appetite, wellbeing, dyspnea) in palliative patients.

Question 55: A patient with lung cancer develops facial plethora, arm edema, and distended neck veins. Which imaging study is the priority?

Bone scan
Echocardiogram
MRI brain
CT chest with contrast (Correct answer)

Correct answer: CT chest with contrast

CT chest with contrast delineates the extent of superior vena cava (SVC) obstruction and identifies the underlying mass causing it.

Question 56: Syndrome of inappropriate antidiuretic hormone secretion (SIADH) in cancer is best managed initially with:

Fluid restriction to 800–1000 mL/day (Correct answer)
IV 3% hypertonic saline immediately
Diuresis with furosemide alone
Oral sodium supplementation

Correct answer: Fluid restriction to 800–1000 mL/day

Mild to moderate SIADH is first managed with fluid restriction; hypertonic saline is reserved for severe symptomatic hyponatremia.

Question 57: A patient is diagnosed with acute promyelocytic leukemia (APL, AML-M3). Which agent is a cornerstone of induction therapy that induces differentiation of malignant promyelocytes?

All-trans retinoic acid (ATRA) (Correct answer)
Hydroxyurea
Cytarabine (ara-C)
Daunorubicin

Correct answer: All-trans retinoic acid (ATRA)

ATRA targets the PML-RARA fusion protein in APL, promoting differentiation of malignant promyelocytes and is combined with arsenic trioxide or anthracyclines for induction.

Question 58: Which electrolyte abnormality is NOT typically associated with tumor lysis syndrome (TLS)?

Hypocalcemia
Hypernatremia (Correct answer)
Hyperphosphatemia
Hyperkalemia

Correct answer: Hypernatremia

TLS is characterized by hyperkalemia, hyperphosphatemia, hypocalcemia, and hyperuricemia resulting from massive cell lysis; sodium levels are not directly affected by intracellular contents.

Question 59: Enhanced Recovery After Surgery (ERAS) protocols in oncologic surgery are designed to achieve which primary goal?

Reduce surgical stress response, accelerate recovery, and decrease complications (Correct answer)
Mandate 5-day hospital stays after major resections
Avoid nutritional support in the perioperative period
Eliminate the need for postoperative pain medication

Correct answer: Reduce surgical stress response, accelerate recovery, and decrease complications

ERAS (Enhanced Recovery After Surgery) multimodal pathways reduce postoperative complications and hospital LOS by minimizing physiologic stress through measures including preoperative carbohydrate loading, multimodal analgesia, early ambulation, early enteral nutrition, and restrictive IV fluid management.

Question 60: Concurrent chemoradiation is superior to radiation alone in which cancers because chemotherapy acts as a:

Radiosensitizer that enhances tumor cell kill by radiation (Correct answer)
Radioprotector of normal tissue
Method to reduce radiation dose needed
Substitute for surgery only

Correct answer: Radiosensitizer that enhances tumor cell kill by radiation

Radiosensitizing chemotherapy (e.g., cisplatin, 5-FU) impairs the tumor cell's ability to repair radiation-induced DNA damage, increasing local control and survival.

Question 61: Anticipatory grief is best described as:

Grief that is absent initially and surfaces months later
Complicated grief requiring psychiatric diagnosis
Grief experienced only by the patient, not caregivers
Grief experienced before an expected loss occurs (Correct answer)

Correct answer: Grief experienced before an expected loss occurs

Anticipatory grief occurs before the death and encompasses the losses already experienced and those expected, affecting both patients and families.

Question 62: A patient undergoing allogeneic hematopoietic stem cell transplant develops a diffuse erythematous rash, diarrhea, and elevated bilirubin on day 25. What condition is MOST likely?

Engraftment syndrome
Veno-occlusive disease (VOD/SOS)
Cytomegalovirus (CMV) colitis
Acute graft-versus-host disease (aGVHD) (Correct answer)

Correct answer: Acute graft-versus-host disease (aGVHD)

Rash, diarrhea, and liver dysfunction appearing within 100 days post-allogeneic SCT are the classic triad of acute graft-versus-host disease.

Question 63: Cytokine release syndrome (CRS) after CAR-T cell infusion is most effectively treated in severe cases with which agent?

Rituximab
Tocilizumab (IL-6 receptor antagonist) (Correct answer)
High-dose methotrexate
Cyclophosphamide

Correct answer: Tocilizumab (IL-6 receptor antagonist)

Tocilizumab, an IL-6 receptor antagonist, is the first-line treatment for severe CRS because IL-6 is the primary cytokine driving this toxicity.

Question 64: Which parameter is MOST critical to monitor in a patient receiving high-dose methotrexate therapy?

Serum creatinine and urine pH (Correct answer)
Serum potassium and sodium levels
Liver function tests and bilirubin
Complete blood count and platelet count only

Correct answer: Serum creatinine and urine pH

Methotrexate is renally cleared and crystallizes in acidic urine; monitoring renal function and maintaining urine pH above 7 prevents nephrotoxicity and delayed clearance.

Question 65: Rasburicase is contraindicated in which patient population due to risk of hemolytic anemia?

Patients with renal impairment
Patients with hepatic failure
Patients with G6PD deficiency (Correct answer)
Patients receiving steroids

Correct answer: Patients with G6PD deficiency

Rasburicase generates hydrogen peroxide as a byproduct, which causes oxidative hemolysis in patients with G6PD deficiency.

Question 66: When counseling a patient about germline genetic testing results, which element of informed consent is most critical to address specifically in the oncology genetics context?

The cost of the genomic test and insurance coverage
The laboratory's accreditation status
The turnaround time for results
Implications for at-risk biological relatives and potential psychosocial impact (Correct answer)

Correct answer: Implications for at-risk biological relatives and potential psychosocial impact

A unique feature of germline genetic testing is that results have direct implications for the patient's biological relatives (family members share 50% of DNA). Pre-test counseling must explicitly address the hereditary nature of results, the duty to disclose to at-risk relatives, and potential psychosocial distress. While cost and accreditation matter, they are not the most distinguishing ethical element of genetics counseling.

Question 67: A 60-year-old with newly diagnosed AML has FLT3-ITD mutation. Which agent should be added to standard induction chemotherapy based on current NCCG guidelines?

Enasidenib
Venetoclax
Midostaurin (Correct answer)
Glasdegib

Correct answer: Midostaurin

Midostaurin, a FLT3 inhibitor, significantly improves OS when added to standard 7+3 induction in FLT3-mutated AML (RATIFY trial).

Question 68: Which oncology clinical trial design allows all patients to eventually receive the experimental treatment, eliminating the ethical concern of permanent denial of a potentially beneficial therapy?

Adaptive enrichment trial
Blinded parallel-arm trial
Single-arm Phase II trial
Crossover trial design (Correct answer)

Correct answer: Crossover trial design

In crossover trials, patients receive both the experimental and control treatment sequentially (typically in randomized order with a washout period). This allows all participants to receive the potentially beneficial experimental therapy at some point, addressing the ethical concern of withholding potentially effective treatment and improving statistical efficiency.

Question 69: An oncology NP is managing a patient with cancer anorexia-cachexia syndrome. Which pharmacologic agent has demonstrated short-term improvement in appetite and quality of life in this population?

Megestrol acetate (Megace) (Correct answer)
Metformin
High-dose multivitamin supplementation
Erythropoiesis-stimulating agents

Correct answer: Megestrol acetate (Megace)

Megestrol acetate (a progestational agent) improves appetite and caloric intake in cancer-related anorexia-cachexia, though it does not improve survival.

Question 70: Which action is central to the NURSE communication framework used in delivering serious news to cancer patients?

Naming, understanding, respecting, supporting, and exploring emotions (Correct answer)
Notifying the family before the patient
Assessing nurse competency in oncology
Narrating the medical history clearly

Correct answer: Naming, understanding, respecting, supporting, and exploring emotions

The NURSE acronym (Name, Understand, Respect, Support, Explore) guides clinicians in empathically acknowledging and responding to patient emotions.

Question 71: Which statement best describes the rationale for using combination chemotherapy regimens in oncology?

To eliminate the need for supportive care medications
To shorten infusion time for patient convenience
To target multiple mechanisms, reduce drug resistance, and allow lower individual doses to minimize toxicity (Correct answer)
To reduce total drug costs for the healthcare system

Correct answer: To target multiple mechanisms, reduce drug resistance, and allow lower individual doses to minimize toxicity

Combination chemotherapy targets different cell-cycle phases and mechanisms, which reduces resistance, improves efficacy, and allows dose reduction of individual agents.

Question 72: Which of the following is the most common cytogenetic abnormality in multiple myeloma that confers a standard-risk prognosis?

t(14;16)
del(17p)
t(4;14)
Hyperdiploidy (Correct answer)

Correct answer: Hyperdiploidy

Hyperdiploidy, typically involving odd-numbered chromosomes, is the most common cytogenetic finding in myeloma and is associated with standard risk.

Question 73: Which of the following best describes the concept of 'total pain' as used in palliative care?

Pain experienced only in the final 48 hours of life
The numeric pain rating on a 0–10 scale
The multidimensional suffering encompassing physical, psychological, social, and spiritual components (Correct answer)
Pain that is unresponsive to opioid therapy

Correct answer: The multidimensional suffering encompassing physical, psychological, social, and spiritual components

Dame Cicely Saunders defined 'total pain' as the interplay of physical, psychological, social, and spiritual dimensions of suffering.

Question 74: When obtaining informed consent for a Phase I oncology clinical trial, which element distinguishes informed consent in this context from standard treatment consent?

Consent can be waived if the patient has limited treatment options
Patients in Phase I trials are not permitted to withdraw consent after enrollment
Patients must be informed that the primary purpose is to determine safety and dose, not to achieve tumor response (Correct answer)
A legally authorized representative may consent on behalf of a competent adult patient

Correct answer: Patients must be informed that the primary purpose is to determine safety and dose, not to achieve tumor response

A critical and ethically mandated element of Phase I trial consent is explicitly informing participants that the primary objective is to evaluate safety, pharmacokinetics, and determine the maximum tolerated dose — not to provide therapeutic benefit. This distinction addresses therapeutic misconception, where participants mistakenly believe the trial is primarily designed to help them. Consent cannot be waived for competent adults. A competent adult must consent personally. Withdrawal of consent is always permitted.

Question 75: Cancer-associated cachexia is best characterized by which of the following pathophysiologic features?

A temporary anorexic state that resolves upon completion of chemotherapy
Metabolic dysregulation with systemic inflammation causing loss of muscle and fat that is not fully reversible with nutrition alone (Correct answer)
Pure caloric deficiency reversible solely through caloric supplementation
Isolated fat loss without muscle wasting driven by voluntary food restriction

Correct answer: Metabolic dysregulation with systemic inflammation causing loss of muscle and fat that is not fully reversible with nutrition alone

Cancer cachexia is a complex metabolic syndrome characterized by systemic inflammation (elevated IL-6, TNF-α, etc.), increased catabolism, and negative protein and energy balance. Critically, it is NOT simply starvation — aggressive caloric supplementation alone cannot fully reverse the muscle wasting because the underlying metabolic dysfunction persists. This distinguishes cachexia from malnutrition alone and explains why nutritional support must be multimodal.

Question 76: Which measurement best indicates that a patient is at high risk of imminent death (hours to days) in the inpatient palliative setting?

Decreased urine output, mottling, irregular respirations, and unresponsiveness (Correct answer)
Mild confusion in the morning
Refusal of one meal
Pain score of 8/10 with stable vitals

Correct answer: Decreased urine output, mottling, irregular respirations, and unresponsiveness

Decreased urine output, mottled skin, irregular breathing patterns, and unresponsiveness are reliable clinical signs of imminent death within hours to days.

Question 77: A patient completing chemoradiation for anal cancer asks when to expect treatment response assessment. What is the correct nurse response?

A PET-CT is performed immediately after the last radiation fraction
Surgical resection is scheduled within 2 weeks if no visible response is seen
Response cannot be assessed; surveillance colonoscopy is the only follow-up needed
Response is typically assessed 8–12 weeks after treatment completion due to continued tumor regression (Correct answer)

Correct answer: Response is typically assessed 8–12 weeks after treatment completion due to continued tumor regression

Anal cancer continues to regress for up to 12 weeks post-treatment, so response assessment is deferred to allow full tumor response before determining further management.

Question 78: An AOCNP is counseling the family of a dying patient about the 'death rattle.' Which statement is most accurate?

The sound indicates the patient is in severe pain
It only occurs in patients who received opioids
Suctioning the throat is the most effective treatment
It is caused by retained secretions and is usually not distressing to the patient (Correct answer)

Correct answer: It is caused by retained secretions and is usually not distressing to the patient

The death rattle results from retained oropharyngeal secretions in a semi-comatose patient and is typically not distressing to the patient, though it may distress families.

Question 79: The nurse is looking through the records of a patient who has just received a diagnosis of chronic lymphocytic leukemia. Which of the following laboratory results should be anticipated?

Elevated sedimentation rate
Elevated aspartate aminotransferase and alanine aminotransferase levels
Uncontrolled proliferation of granulocytes
Thrombocytopenia and increased lymphocytes (Correct answer)

Correct answer: Thrombocytopenia and increased lymphocytes

A proliferation of tiny, abnormally developed B cells and a decline in antibody response are two characteristics of chronic lymphocytic leukemia. Thrombocytopenia is frequently seen as well.

Question 80: The HPV vaccine is most effective when administered:

Before sexual debut, ideally at age 11–12 (Correct answer)
After first sexual exposure
At any age up to 50 without preference
Only to females younger than 18

Correct answer: Before sexual debut, ideally at age 11–12

HPV vaccination generates the highest immune response and provides complete protection when given before HPV exposure, which is why it is recommended at age 11–12.

Question 81: A patient with advanced pancreatic cancer reports severe neuropathic pain described as burning and shooting despite adequate opioid dosing. Which adjuvant analgesic has the best evidence as a first-line addition?

Topical capsaicin 0.025% cream alone
Vitamin B12 supplementation
Tricyclic antidepressant (nortriptyline) or gabapentinoid (gabapentin/pregabalin) (Correct answer)
Oral antihistamine (diphenhydramine)

Correct answer: Tricyclic antidepressant (nortriptyline) or gabapentinoid (gabapentin/pregabalin)

Tricyclic antidepressants and gabapentinoids are first-line adjuvant analgesics for neuropathic pain in cancer patients, per NCCN and WHO guidelines.

Question 82: During a routine follow-up visit, the family caregiver of a patient with advanced cancer appears exhausted and tearful, stating 'I can't do this anymore.' Which of the following best represents the oncology NP's priority response?

Conduct a formal caregiver burden assessment and connect the caregiver with psychosocial support resources (Correct answer)
Suggest the patient consider inpatient hospice to relieve caregiver burden
Reassure the caregiver that the patient's disease trajectory will improve
Document caregiver distress and follow up at the next scheduled visit

Correct answer: Conduct a formal caregiver burden assessment and connect the caregiver with psychosocial support resources

Caregiver burden is a recognized domain of oncology NP practice. The priority is to formally assess the caregiver's level of distress (tools include the Zarit Burden Interview or Caregiver Strain Index) and immediately connect them with available support resources — social work, caregiver support groups, respite care options. Deferring assessment is a patient safety concern. Reassurance minimizes a real crisis. Inpatient hospice may not be appropriate or desired and leapfrogs assessment.

Question 83: A hospice patient develops myoclonic jerks and hyperalgesia after high-dose morphine. Which action best addresses opioid-induced neurotoxicity?

Discontinue all opioids and treat with NSAIDs
Opioid rotation to a different agent such as hydromorphone (Correct answer)
Increase morphine to overcome tolerance
Add lorazepam to suppress myoclonus only

Correct answer: Opioid rotation to a different agent such as hydromorphone

Opioid rotation (switching to an equianalgesic dose of a different opioid) reduces neurotoxic metabolite accumulation and relieves opioid-induced neurotoxicity.

Question 84: A patient receiving whole brain radiation therapy (WBRT) asks about long-term cognitive effects. Which statement by the nurse is most accurate?

Cognitive decline is a recognized late effect, and memantine may reduce its severity (Correct answer)
WBRT does not cause cognitive changes because the dose is kept low
Only patients over age 70 experience long-term cognitive changes from WBRT
Cognitive effects are temporary and fully resolve within 6 months

Correct answer: Cognitive decline is a recognized late effect, and memantine may reduce its severity

Radiation-induced neurocognitive decline is a known late effect of WBRT, and clinical trials support memantine use to help preserve cognitive function.

Question 85: A patient receiving whole-brain radiation therapy (WBRT) is at highest risk for which late cognitive effect?

Peripheral neuropathy
Renal toxicity
Radiation-induced cognitive decline including memory and executive function deficits (Correct answer)
Hepatic failure

Correct answer: Radiation-induced cognitive decline including memory and executive function deficits

WBRT damages white matter and the hippocampus, producing progressive neurocognitive decline, particularly affecting memory and processing speed months to years later.

Question 86: The ACS recommends that average-risk adults begin colorectal cancer screening at which age?

40 years
45 years (Correct answer)
55 years
50 years

Correct answer: 45 years

The ACS updated its recommendation in 2018 to begin colorectal cancer screening at age 45 for average-risk adults due to rising incidence in younger populations.

Question 87: Which wound complication is most specifically associated with colorectal resection surgery and manifests as separation of abdominal fascial layers?

Anastomotic leak
Superficial surgical site infection
Enterocutaneous fistula formation
Wound dehiscence (fascial separation) (Correct answer)

Correct answer: Wound dehiscence (fascial separation)

Wound dehiscence (separation of fascial wound layers) is a serious complication of abdominal surgery, more common in patients who are immunocompromised, malnourished, obese, or received preoperative radiation/steroids. It requires urgent surgical consultation and may progress to evisceration if full-thickness.

Question 88: What is the primary goal of palliative care in oncology?

To provide only end-of-life hospice care
To improve quality of life by preventing and relieving suffering (Correct answer)
To hasten death when curative options are exhausted
To replace disease-directed therapy entirely

Correct answer: To improve quality of life by preventing and relieving suffering

Palliative care focuses on improving quality of life for patients and families by addressing physical, emotional, and spiritual suffering at any disease stage.

Question 89: Superior vena cava (SVC) syndrome with acute airway compromise and cerebral edema should be treated FIRST with which intervention?

Surgical bypass grafting of the SVC
Emergent SVC stenting or radiation therapy (Correct answer)
High-dose systemic corticosteroids alone
Anticoagulation with unfractionated heparin

Correct answer: Emergent SVC stenting or radiation therapy

Emergent endovascular SVC stenting provides the fastest relief of obstruction and is preferred for acute life-threatening SVC syndrome; radiation may follow once airway is stabilized.

Question 90: Helicobacter pylori eradication is a primary prevention strategy for which cancer?

Esophageal adenocarcinoma
Gastric adenocarcinoma and gastric MALT lymphoma (Correct answer)
Colorectal cancer
Hepatocellular carcinoma

Correct answer: Gastric adenocarcinoma and gastric MALT lymphoma

H. pylori is a WHO Group 1 carcinogen; chronic infection causes gastric mucosal inflammation progressing to atrophy, metaplasia, dysplasia, and ultimately gastric cancer.

Question 91: A patient receiving radiation to the thorax develops a dry cough and low-grade fever 6 weeks post-treatment. Which complication should the nurse suspect first?

Bacterial pneumonia
Pulmonary embolism
Radiation pneumonitis (Correct answer)
Radiation esophagitis recurrence

Correct answer: Radiation pneumonitis

Radiation pneumonitis typically presents 4–12 weeks after thoracic irradiation with dry cough, dyspnea, and low-grade fever.

Question 92: A patient with AML develops bleeding gums, petechiae, prolonged PT/PTT, low fibrinogen, and elevated D-dimer. Which treatment is specific to this etiology?

Platelet transfusion alone
All-trans retinoic acid (ATRA) (Correct answer)
Heparin infusion
Fresh frozen plasma alone

Correct answer: All-trans retinoic acid (ATRA)

ATRA induces differentiation of promyelocytes in APL-associated DIC, addressing the underlying cause rather than just replacing clotting factors.

Question 93: Which cervical cancer screening strategy is currently recommended for average-risk women aged 30–65?

No screening after age 30 if vaccinated
HPV testing annually
Annual Pap smear without HPV co-testing
Co-testing with Pap smear and HPV test every 5 years OR Pap smear alone every 3 years (Correct answer)

Correct answer: Co-testing with Pap smear and HPV test every 5 years OR Pap smear alone every 3 years

ASCCP and USPSTF guidelines recommend co-testing every 5 years or cytology alone every 3 years for women aged 30–65 at average risk.

Question 94: The Edmonton Symptom Assessment System (ESAS) measures which of the following?

Functional status using a 0–100% scale
Opioid equianalgesic conversions
Prognosis using lab values and symptoms
Nine common symptoms including pain, fatigue, and anxiety on a 0–10 scale (Correct answer)

Correct answer: Nine common symptoms including pain, fatigue, and anxiety on a 0–10 scale

The ESAS assesses nine symptoms (pain, fatigue, nausea, depression, anxiety, drowsiness, appetite, wellbeing, dyspnea) each on a 0–10 scale.

Question 95: A cancer patient presents with fever, confusion, and diffuse petechiae. Labs show thrombocytopenia, elevated D-dimer, prolonged PT/PTT, and low fibrinogen. Which emergent condition requires immediate treatment?

Heparin-induced thrombocytopenia (HIT)
Disseminated intravascular coagulation (DIC) (Correct answer)
Immune thrombocytopenic purpura (ITP)
Thrombotic thrombocytopenic purpura (TTP)

Correct answer: Disseminated intravascular coagulation (DIC)

DIC is characterized by simultaneous thrombosis and hemorrhage with consumption of clotting factors (low fibrinogen, elevated D-dimer, prolonged PT/PTT) and is a life-threatening emergency requiring urgent treatment.

Question 96: A survivor reports persistent fear of cancer recurrence (FCR) that impairs daily functioning 3 years post-treatment. The FIRST-LINE psychological intervention recommended by oncology guidelines is:

Long-term benzodiazepine therapy
Peer support groups only
Cognitive behavioral therapy (CBT) (Correct answer)
Watchful waiting for spontaneous resolution

Correct answer: Cognitive behavioral therapy (CBT)

Cognitive behavioral therapy is the most evidence-based psychological intervention for clinically significant fear of cancer recurrence in survivors.

Question 97: Which intervention is contraindicated in the initial management of SVC syndrome with thrombosis?

Catheter-directed thrombolysis
Glucocorticoids for symptom relief
Immediate surgical resection as first-line therapy (Correct answer)
Anticoagulation

Correct answer: Immediate surgical resection as first-line therapy

Immediate surgery is not first-line for SVC syndrome with thrombosis; less invasive options such as anticoagulation, thrombolysis, and stenting are preferred.

Question 98: Brachytherapy differs from external beam radiation in that brachytherapy:

Requires no treatment planning
Uses a linear accelerator outside the body
Places radioactive sources directly inside or adjacent to the tumor (Correct answer)
Delivers protons rather than photons

Correct answer: Places radioactive sources directly inside or adjacent to the tumor

Brachytherapy involves placing sealed radioactive sources (e.g., iridium-192, iodine-125, palladium-103) within or near the tumor. This delivers highly localized doses to the tumor while sparing surrounding normal tissue. It is used for cervical, prostate, breast, and esophageal cancers among others.

Question 99: Which ethical principle is most directly invoked when a palliative care NP provides high-dose opioids for refractory symptoms, accepting that respiratory depression is a possible but unintended side effect?

Autonomy
Doctrine of double effect (Correct answer)
Justice
Veracity

Correct answer: Doctrine of double effect

The doctrine of double effect justifies an action with both good (symptom relief) and potentially bad (respiratory depression) effects when the intent is the good effect and the good outweighs the harm.

Question 100: Which of the following is the FIRST-LINE treatment for malignant spinal cord compression (MSCC) once the diagnosis is confirmed?

IV bisphosphonate therapy
High-dose corticosteroids (dexamethasone) (Correct answer)
Surgical decompression
Emergent radiation therapy

Correct answer: High-dose corticosteroids (dexamethasone)

High-dose dexamethasone should be initiated immediately upon suspicion or confirmation of MSCC to reduce cord edema and preserve neurological function while definitive therapy is arranged.

Question 101: Which intervention is most effective for managing malignant bowel obstruction in a patient with poor prognosis who is not a surgical candidate?

High-dose laxatives
Total parenteral nutrition as primary therapy
Octreotide plus corticosteroids plus antiemetics (Correct answer)
Nasogastric tube feeding indefinitely

Correct answer: Octreotide plus corticosteroids plus antiemetics

Octreotide reduces intestinal secretions, corticosteroids reduce perilesional edema, and antiemetics manage nausea — this triad palliates MBO without surgery.

Question 102: A patient in the last hours of life becomes agitated and confused despite opioid therapy. Which intervention is most appropriate for managing terminal restlessness/agitation?

Initiate empiric antibiotics for presumed delirium from infection
Add a benzodiazepine (e.g., midazolam or lorazepam) or neuroleptic (e.g., haloperidol) alongside opioids (Correct answer)
Increase opioid dose as the sole intervention
Apply physical restraints to protect the patient

Correct answer: Add a benzodiazepine (e.g., midazolam or lorazepam) or neuroleptic (e.g., haloperidol) alongside opioids

Terminal agitation is best managed by combining opioids with a benzodiazepine (midazolam, lorazepam) or haloperidol to address the neuropsychiatric component of distress.

Question 103: Which laboratory finding is most consistent with tumor lysis syndrome?

Hypokalemia, hypophosphatemia, hypercalcemia
Hypernatremia, hypophosphatemia, hypercalcemia
Hyperkalemia, hyperphosphatemia, hypocalcemia, hyperuricemia (Correct answer)
Hyponatremia, hyperchloremia, hypercalcemia

Correct answer: Hyperkalemia, hyperphosphatemia, hypocalcemia, hyperuricemia

Tumor lysis syndrome is characterized by hyperkalemia, hyperphosphatemia, hypocalcemia, and hyperuricemia from massive cell death.

Question 104: A patient with lymphoma undergoing induction chemotherapy develops rising creatinine, oliguria, and uric acid of 12 mg/dL. Allopurinol was started 24 hours ago. Which agent should be added to address established hyperuricemia?

Febuxostat
Colchicine
Probenecid
Rasburicase (Correct answer)

Correct answer: Rasburicase

Rasburicase is a recombinant urate oxidase that rapidly converts existing uric acid to allantoin (a soluble metabolite) and is preferred when hyperuricemia is already established, unlike allopurinol which only prevents new formation.

Question 105: Which complication is most commonly associated with total gastrectomy for gastric cancer and requires lifelong supplementation?

Iron deficiency requiring IV iron infusion only
Vitamin D deficiency from malabsorption
Vitamin B12 deficiency due to loss of intrinsic factor (Correct answer)
Calcium deficiency causing osteoporosis

Correct answer: Vitamin B12 deficiency due to loss of intrinsic factor

The stomach produces intrinsic factor, essential for vitamin B12 absorption in the terminal ileum. Total gastrectomy eliminates intrinsic factor production, causing pernicious anemia. Patients require lifelong vitamin B12 supplementation, typically by intramuscular injection since oral absorption is absent without intrinsic factor.

Question 106: A patient with malignant bowel obstruction is not a surgical candidate. Which combination is most appropriate for symptom management?

Opioids for pain, an antisecretory agent, and antiemetics (Correct answer)
High-dose laxatives and oral fluids only
Parenteral nutrition and nasogastric suction indefinitely
High-fiber diet and prokinetic agents

Correct answer: Opioids for pain, an antisecretory agent, and antiemetics

Malignant bowel obstruction is managed with opioids for pain/colic, antisecretory agents (e.g., octreotide or hyoscine) to reduce secretions, and antiemetics.

Question 107: A patient receiving pembrolizumab develops severe, grade 3 immune-related pneumonitis. What is the most appropriate initial management?

Hold pembrolizumab and begin inhaled corticosteroids
Continue pembrolizumab at reduced dose
Switch to a different checkpoint inhibitor
Permanently discontinue pembrolizumab and start high-dose corticosteroids (Correct answer)

Correct answer: Permanently discontinue pembrolizumab and start high-dose corticosteroids

Grade 3–4 immune-related pneumonitis requires permanent discontinuation of the checkpoint inhibitor and initiation of high-dose systemic corticosteroids (prednisone 1–2 mg/kg/day or methylprednisolone IV), with pulmonology consultation. This is a potentially life-threatening irAE.

Question 108: According to the TNM staging system, which descriptor indicates that cancer cells have spread to regional lymph nodes?

G2
M1
T2
N1 (Correct answer)

Correct answer: N1

In the TNM system, N describes regional lymph node involvement (N0 = no nodes, N1+ = regional node spread). T describes primary tumor size/extension, M describes distant metastasis, and G describes histologic grade. N1 specifically indicates spread to regional lymph nodes, which is a critical staging determinant affecting treatment planning.

Question 109: Dump syndrome following gastric surgery or esophagectomy is characterized by which symptom cluster?

Constipation, abdominal distension, weight gain
Obstipation and progressive vomiting
Nausea, diarrhea, diaphoresis, palpitations after eating (early) or hypoglycemia (late) (Correct answer)
Severe heartburn and regurgitation

Correct answer: Nausea, diarrhea, diaphoresis, palpitations after eating (early) or hypoglycemia (late)

Dumping syndrome results from rapid gastric emptying of hyperosmolar contents into the small bowel. Early dumping (within 30 min) causes GI symptoms (nausea, cramping, diarrhea) and vasomotor symptoms (flushing, diaphoresis, tachycardia). Late dumping (1–3 h) causes reactive hypoglycemia. Management includes dietary modifications and small frequent meals.

Question 110: A patient with Waldenström macroglobulinemia (WM) presents with headache, blurred vision, dizziness, and epistaxis. Which pathophysiologic mechanism best explains these symptoms?

Hyperviscosity syndrome caused by high levels of circulating IgM monoclonal protein (Correct answer)
Bone marrow failure causing severe thrombocytopenia and spontaneous bleeding
Leptomeningeal involvement by lymphoplasmacytic lymphoma
CRAB criteria-related renal insufficiency causing uremic encephalopathy

Correct answer: Hyperviscosity syndrome caused by high levels of circulating IgM monoclonal protein

WM produces large amounts of IgM, which due to its pentameric structure dramatically increases serum viscosity, causing hyperviscosity syndrome manifesting as neurologic symptoms, visual disturbances, and bleeding from mucosal surfaces.

Question 111: Which statement best describes the role of tumor mutational burden (TMB) in immunotherapy?

High TMB predicts resistance to PD-1/PD-L1 inhibitors in all cancers
TMB is used to select patients for EGFR-targeted therapy
Low TMB is required for CAR-T cell eligibility
High TMB is associated with more neoantigens and potentially greater response to checkpoint inhibitors (Correct answer)

Correct answer: High TMB is associated with more neoantigens and potentially greater response to checkpoint inhibitors

Tumors with high TMB produce more neoantigens, which can be recognized by the immune system, potentially enhancing response to checkpoint inhibitors.

Question 112: Which diagnostic test is most sensitive and specific for detecting and quantifying the monoclonal protein (M-protein) in multiple myeloma?

24-hour urine protein excretion
Bone marrow biopsy alone
Serum protein electrophoresis (SPEP) combined with serum immunofixation electrophoresis (IFE) (Correct answer)
Complete blood count with differential

Correct answer: Serum protein electrophoresis (SPEP) combined with serum immunofixation electrophoresis (IFE)

SPEP quantifies the M-protein spike and immunofixation identifies its heavy and light chain type; together they are the gold standard for detecting and characterizing monoclonal immunoglobulins in myeloma.

Question 113: Which biomarker combination is currently FDA-approved for multi-cancer early detection (MCED) screening in average-risk adults?

Liquid biopsy for KRAS mutations only
Cell-free DNA methylation pattern analysis (e.g., Galleri test) (Correct answer)
CA-125 + CEA + AFP panel
Circulating tumor cells with PSA

Correct answer: Cell-free DNA methylation pattern analysis (e.g., Galleri test)

The Galleri test analyzes cell-free DNA methylation patterns and is FDA-authorized for multi-cancer early detection, identifying signal across 50+ cancer types.

Question 114: Which validated screening tool is most widely recommended for identifying nutritional risk in hospitalized oncology patients?

Serum albumin level as a sole indicator
NRS-2002 (Nutritional Risk Screening 2002) or MUST (Malnutrition Universal Screening Tool) (Correct answer)
BMI calculation alone
24-hour dietary recall interview

Correct answer: NRS-2002 (Nutritional Risk Screening 2002) or MUST (Malnutrition Universal Screening Tool)

The NRS-2002 and MUST are validated, guideline-endorsed tools for systematic nutritional risk screening in hospitalized patients, including those with cancer. They account for BMI, recent weight loss, reduced intake, and disease severity. BMI alone misses patients with significant weight loss but normal BMI. Serum albumin reflects inflammation as much as nutrition and is no longer recommended as a sole nutritional marker. A 24-hour recall is an assessment tool, not a validated screening instrument.

Question 115: Which grading system is used by oncology nurses to assess and document radiation-induced side effects including mucositis and dermatitis?

NCI-ODWG grading
ECOG Performance Status Scale
CTCAE (Common Terminology Criteria for Adverse Events) (Correct answer)
Karnofsky Performance Scale

Correct answer: CTCAE (Common Terminology Criteria for Adverse Events)

The CTCAE (published by NCI) is the standardized system for grading adverse events in oncology, grading toxicities from 1 (mild) to 5 (death). Radiation-induced dermatitis, mucositis, esophagitis, and other toxicities are all graded using CTCAE criteria.

Question 116: Which agent is used as first-line prophylaxis against tumor lysis syndrome in high-risk patients?

Hydroxyurea
Rasburicase
Allopurinol (Correct answer)
Sodium bicarbonate

Correct answer: Allopurinol

Allopurinol inhibits xanthine oxidase and is the standard first-line prophylactic agent for intermediate- and high-risk TLS.

Question 117: Which finding on a lung cancer screening LDCT result would prompt immediate further workup rather than routine annual follow-up?

A 7 mm part-solid nodule with solid component greater than 6 mm (Correct answer)
Two calcified granulomas
A 4 mm solid nodule
A 3 mm ground-glass nodule

Correct answer: A 7 mm part-solid nodule with solid component greater than 6 mm

Per Lung-RADS, a part-solid nodule with solid component >6 mm is classified as Lung-RADS 4B requiring tissue sampling or PET/CT, not routine follow-up.

Question 118: Burkitt lymphoma is characterized by translocation of the MYC oncogene, most commonly t(8;14). Which virus is most strongly associated with the endemic (African) form of Burkitt lymphoma?

Human herpesvirus 8 (HHV-8)
Hepatitis C virus (HCV)
Human T-lymphotropic virus type 1 (HTLV-1)
Epstein-Barr virus (EBV) (Correct answer)

Correct answer: Epstein-Barr virus (EBV)

EBV is detected in virtually all cases of endemic Burkitt lymphoma in equatorial Africa, where it acts as a cofactor alongside malaria-driven B-cell proliferation and MYC translocation.

Question 119: Which cancer type is most commonly associated with disseminated intravascular coagulation (DIC) in adults?

Melanoma
Colorectal cancer
Renal cell carcinoma
Acute promyelocytic leukemia (APL) (Correct answer)

Correct answer: Acute promyelocytic leukemia (APL)

APL releases tissue factor and procoagulant granules, causing the most severe DIC of any malignancy.

Question 120: A patient with multiple myeloma develops acute flaccid paraplegia with urinary retention. MRI shows vertebral compression at T6 with epidural extension. Surgical evaluation is obtained. What is the PRIMARY factor determining eligibility for surgical decompression over radiation alone?

Patient's overall performance status and life expectancy (Correct answer)
Sensitivity of the underlying malignancy to radiation
Duration of neurological symptoms less than 24 hours
Presence of pathological fracture at the affected level

Correct answer: Patient's overall performance status and life expectancy

Patient performance status and prognosis (expected survival >3 months) are the primary determinants of whether surgical decompression is appropriate, as surgery offers no benefit to patients who cannot tolerate the procedure or have very limited life expectancy.

Question 121: An AOCNP is reviewing risk stratification for hepatocellular carcinoma (HCC) screening. Which patient population has a clear evidence-based indication for surveillance?

Adults over 60 with elevated alkaline phosphatase
Patients with NAFLD and obesity without confirmed cirrhosis
All patients with hepatitis C virus exposure, regardless of fibrosis stage
Patients with cirrhosis from any cause and hepatitis B carriers with high viral load or family history (Correct answer)

Correct answer: Patients with cirrhosis from any cause and hepatitis B carriers with high viral load or family history

HCC surveillance with ultrasound ± AFP every 6 months is recommended for patients with cirrhosis of any etiology and for hepatitis B carriers meeting AASLD high-risk criteria.

Question 122: Which dietary modification is MOST important to counsel a patient receiving warfarin for cancer-associated thrombosis?

Increase calcium-rich foods to counteract bone density loss
Maintain consistent vitamin K intake rather than eliminating it (Correct answer)
Eliminate all leafy green vegetables from the diet
Avoid all grapefruit to prevent CYP3A4 interaction

Correct answer: Maintain consistent vitamin K intake rather than eliminating it

Patients on warfarin should maintain consistent, not zero, vitamin K intake because dramatic fluctuations destabilize INR more than a steady moderate intake.

Question 123: A patient post-Whipple procedure (pancreaticoduodenectomy) on day 2 develops significant drainage from the drain with amylase level >3× the serum amylase. This indicates which complication?

Anastomotic hemorrhage
Postoperative pancreatic fistula (POPF) (Correct answer)
Delayed gastric emptying
Bile leak

Correct answer: Postoperative pancreatic fistula (POPF)

Postoperative pancreatic fistula is defined by drain amylase >3× the upper limit of normal serum amylase on or after postoperative day 3. It is one of the most common serious complications after Whipple procedure, graded A (biochemical leak) to C (severe, requiring reoperation).

Question 124: Cardiotoxicity monitoring in cancer survivors who received anthracyclines includes which primary surveillance modality?

Echocardiogram or MUGA scan to assess left ventricular ejection fraction (LVEF) (Correct answer)
Coronary angiography every 5 years
12-lead ECG annually
Cardiac biomarkers (troponin) weekly for 1 year

Correct answer: Echocardiogram or MUGA scan to assess left ventricular ejection fraction (LVEF)

Anthracyclines (doxorubicin, epirubicin) cause dose-dependent cardiomyopathy through oxidative damage to cardiomyocytes. Survivors require baseline and periodic echocardiogram (or MUGA) assessment of LVEF, especially those who received cumulative doxorubicin doses >300 mg/m² or combined with chest radiation or trastuzumab.

Question 125: A patient with multiple myeloma develops hypercalcemia of malignancy. Which mechanism is primarily responsible?

Increased vitamin D absorption from the gut
Osteoclast activation by RANKL overexpression from myeloma cells (Correct answer)
Increased renal calcium reabsorption from PTH excess
Parathyroid gland hyperplasia

Correct answer: Osteoclast activation by RANKL overexpression from myeloma cells

Myeloma cells overexpress RANKL and other osteoclast-activating factors, leading to osteolytic bone destruction and calcium release into the bloodstream.

Question 126: A Phase III oncology trial reports a hazard ratio (HR) of 0.72 (95% CI: 0.58–0.89) for progression-free survival. How should this result be interpreted?

The experimental arm is inferior to control
The experimental arm reduces the risk of progression by 28% compared to control, with a statistically significant result (Correct answer)
The experimental arm has 72% greater risk of progression than control
The result is not statistically significant because the HR is less than 1.0

Correct answer: The experimental arm reduces the risk of progression by 28% compared to control, with a statistically significant result

An HR of 0.72 means the experimental treatment reduces the instantaneous risk of progression by 28% compared to control (1 - 0.72 = 0.28). The 95% confidence interval (0.58–0.89) does not cross 1.0, confirming statistical significance. HR <1 always favors the experimental arm for time-to-event outcomes.

Question 127: A patient with a 2.5 cm breast mass has biopsy confirming invasive ductal carcinoma. Imaging shows 2 ipsilateral axillary lymph nodes with malignant features and no distant metastasis. What is the clinical TNM stage?

Stage IIB (T2 N1 M0) (Correct answer)
Stage IIIA (T2 N2 M0)
Stage IIA (T2 N1 M0)
Stage IV (T2 N1 M1)

Correct answer: Stage IIB (T2 N1 M0)

Per AJCC 8th edition, a primary tumor 2–5 cm (T2) with metastasis in 1–3 ipsilateral axillary lymph nodes (N1) and no distant metastasis (M0) classifies as Stage IIB. Stage IIA would be T0-T2 N1 M0 only if T0-1; with T2 and N1, the anatomic stage is IIB. Stage IIIA requires N2 (4–9 nodes) with T2, or T3 with N1. Stage IV requires distant metastasis (M1).

Question 128: Radiation recall is an acute dermatitis reaction triggered by certain chemotherapy agents administered after prior radiation. Which agent is most classically associated with radiation recall?

Vincristine
Carboplatin
Doxorubicin (Adriamycin) (Correct answer)
Cyclophosphamide

Correct answer: Doxorubicin (Adriamycin)

Radiation recall is an inflammatory skin reaction in a previously irradiated field triggered by certain drugs, most classically anthracyclines (doxorubicin), gemcitabine, taxanes, and capecitabine. It can occur weeks to years after radiation and may also affect internal organs.

Question 129: Which targeted therapy is a monoclonal antibody that blocks the HER2 receptor in HER2-positive breast cancer?

Imatinib
Trastuzumab (Correct answer)
Bevacizumab
Erlotinib

Correct answer: Trastuzumab

Trastuzumab (Herceptin) binds the extracellular domain of HER2, inhibiting downstream proliferative signaling and mediating antibody-dependent cytotoxicity.

Question 130: A patient on long-acting opioids reports breakthrough pain. The appropriate breakthrough dose is approximately:

50% of the total daily opioid dose
A fixed 5 mg morphine dose regardless of baseline
100% of the single long-acting dose
10–15% of the total daily opioid dose (Correct answer)

Correct answer: 10–15% of the total daily opioid dose

Breakthrough doses are typically 10–15% of the total 24-hour opioid dose to provide proportionate rapid-onset analgesia.

Question 131: A patient with colon cancer on bevacizumab presents with sudden-onset severe abdominal pain, tachycardia, and signs of peritonitis. Which bevacizumab-associated oncologic emergency should be suspected?

Gastrointestinal perforation (Correct answer)
Venous thrombosis of mesenteric vessels
Hypersensitivity anaphylaxis
Bevacizumab-induced thrombocytopenia

Correct answer: Gastrointestinal perforation

Gastrointestinal perforation is a serious known complication of bevacizumab (VEGF inhibitor) due to impaired wound healing and mucosal integrity, occurring in approximately 1-2% of treated patients.

Question 132: When converting a patient from IV hydromorphone 1.5 mg/hour continuous infusion to oral extended-release opioids, the nurse practitioner should:

Simply stop IV and start the oral agent at the same numeric dose
Use a 1:1 ratio because IV and oral doses are equivalent
Double the IV dose to account for oral bioavailability
Calculate total 24-hour IV dose, apply equianalgesic conversion, and reduce by 25–30% for incomplete cross-tolerance (Correct answer)

Correct answer: Calculate total 24-hour IV dose, apply equianalgesic conversion, and reduce by 25–30% for incomplete cross-tolerance

Equianalgesic conversion tables are used to calculate the equivalent oral dose, then a 25–30% reduction is applied to account for incomplete cross-tolerance during opioid rotation.

Question 133: A 45-year-old average-risk woman asks about lung cancer screening. Which criteria must she meet to qualify for low-dose CT (LDCT) screening per current USPSTF guidelines?

Age 55-80, 30 pack-year history, current smoker or quit within 10 years
Age 40-75, any tobacco exposure history
Age 45-75, current smoker only
Age 50-80, 20 pack-year history, current smoker or quit within 15 years (Correct answer)

Correct answer: Age 50-80, 20 pack-year history, current smoker or quit within 15 years

The 2021 USPSTF guidelines recommend annual LDCT for adults aged 50-80 with a 20 pack-year smoking history who currently smoke or quit within the past 15 years.

Question 134: A 45-year-old woman with BRCA1 mutation asks about breast cancer screening recommendations. Which protocol is most appropriate?

Annual mammogram starting at age 40 only
Ultrasound only due to dense breast tissue
Annual MRI plus annual mammogram starting at age 25-30 (Correct answer)
Biennial mammogram starting at age 45

Correct answer: Annual MRI plus annual mammogram starting at age 25-30

BRCA1 carriers should begin annual breast MRI and mammogram at age 25-30 due to significantly elevated lifetime risk.

Question 135: Which blood count threshold typically prompts platelet transfusion in a non-bleeding oncology patient per standard guidelines?

Platelet count below 10,000/mm³ (Correct answer)
Platelet count below 50,000/mm³
Platelet count below 100,000/mm³
Platelet count below 75,000/mm³

Correct answer: Platelet count below 10,000/mm³

Current guidelines recommend prophylactic platelet transfusion at <10,000/mm³ in non-bleeding, hemodynamically stable patients to reduce spontaneous hemorrhage risk.

Question 136: Which electrolyte abnormality most immediately threatens cardiac function in tumor lysis syndrome?

Hypocalcemia
Hyperphosphatemia
Hyperuricemia
Hyperkalemia (Correct answer)

Correct answer: Hyperkalemia

Hyperkalemia causes fatal arrhythmias and is the most immediately life-threatening electrolyte disturbance in TLS.

Question 137: Which statement about neutropenic enterocolitis (typhlitis) in oncology patients is CORRECT?

Immediate surgery is required in all confirmed cases
Oral antibiotics are sufficient for mild cases
It exclusively affects the sigmoid colon
CT scan showing bowel wall thickening ≥4 mm supports the diagnosis (Correct answer)

Correct answer: CT scan showing bowel wall thickening ≥4 mm supports the diagnosis

CT findings of bowel wall thickening ≥4 mm (particularly of the cecum/right colon) combined with neutropenia and abdominal pain support the diagnosis of typhlitis; initial management is usually conservative with bowel rest and broad-spectrum IV antibiotics.

Question 138: A patient enrolled in a clinical trial withdraws consent. What is the correct action regarding their previously collected data?

The patient's data must be excluded from all analyses
All previously collected data must be immediately destroyed
Previously collected data may generally be retained and used per the original consent terms (Correct answer)
The IRB must be notified and all data frozen pending review

Correct answer: Previously collected data may generally be retained and used per the original consent terms

Under most IRB protocols and federal regulations, data collected prior to withdrawal can be retained and analyzed unless the patient specifically requests destruction.

Question 139: A 10-year survivor of breast cancer presents with arm swelling, heaviness, and pitting edema after a recent air travel. The MOST likely diagnosis is:

Radiation fibrosis
Deep vein thrombosis
Lymphedema (Correct answer)
Cellulitis

Correct answer: Lymphedema

Lymphedema is a common late effect following axillary lymph node dissection and/or radiation, and can be triggered or worsened by air travel.

Question 140: A patient with advanced cancer develops hypercalcemia of malignancy (serum calcium 13.5 mg/dL). Which is the first-line pharmacologic treatment?

Oral corticosteroids as the primary treatment
Intravenous bisphosphonate such as zoledronic acid after IV hydration (Correct answer)
Subcutaneous calcitonin as the sole long-term agent
Oral calcium supplements to recalibrate serum levels

Correct answer: Intravenous bisphosphonate such as zoledronic acid after IV hydration

IV hydration followed by an IV bisphosphonate (zoledronic acid or pamidronate) is the first-line treatment for malignancy-associated hypercalcemia.

Question 141: Which intervention has the strongest evidence for primary prevention of hepatocellular carcinoma (HCC)?

Avoidance of raw shellfish
Annual liver ultrasound surveillance
Low-fat diet and exercise
Hepatitis B vaccination (Correct answer)

Correct answer: Hepatitis B vaccination

Hepatitis B vaccination is the most effective primary prevention strategy for HCC by preventing chronic HBV infection, the leading cause of HCC worldwide.

Question 142: A patient with metastatic melanoma on ipilimumab develops diarrhea with 7 stools above baseline per day and cramping. The MOST appropriate management is:

Administer loperamide and continue ipilimumab at the same dose
Discontinue ipilimumab permanently and start infliximab immediately
Hold ipilimumab and initiate high-dose systemic corticosteroids (prednisone 1–2 mg/kg/day) (Correct answer)
Reduce ipilimumab dose by 50% and add bismuth subsalicylate

Correct answer: Hold ipilimumab and initiate high-dose systemic corticosteroids (prednisone 1–2 mg/kg/day)

Grade 3 immune-mediated colitis (≥7 stools above baseline) requires drug hold and high-dose systemic corticosteroids; infliximab is reserved for steroid-refractory cases.

Question 143: A patient with multiple myeloma receiving bortezomib develops new-onset tingling and burning pain in bilateral feet. The MOST appropriate next step is to:

Order an MRI of the lumbar spine only
Switch to carfilzomib and initiate gabapentin (Correct answer)
Administer IV magnesium sulfate for 24 hours
Increase bortezomib dose to achieve faster response

Correct answer: Switch to carfilzomib and initiate gabapentin

Bortezomib causes peripheral neuropathy; switching to subcutaneous carfilzomib (less neurotoxic) and initiating neuropathic pain management with gabapentin is appropriate.

Question 144: A patient with metastatic breast cancer develops altered mental status, polyuria, and constipation. Calcium is 14.2 mg/dL. Which mechanism is MOST responsible for hypercalcemia in solid tumors without bone metastases?

Primary hyperparathyroidism
PTHrP (parathyroid hormone-related protein) secretion (Correct answer)
Excess 1,25-dihydroxyvitamin D production
Osteoclast activation by bone metastases

Correct answer: PTHrP (parathyroid hormone-related protein) secretion

Humoral hypercalcemia of malignancy (HHM) is most commonly caused by tumor secretion of PTHrP, which mimics PTH and increases bone resorption and renal calcium reabsorption.

Question 145: The Revised International Prognostic Scoring System (IPSS-R) for MDS incorporates which of the following factors to assign risk category?

Cytogenetic risk group, bone marrow blast percentage, hemoglobin, platelet count, and absolute neutrophil count (Correct answer)
Number of mutations by next-generation sequencing, blast percentage, and transfusion history
Age, comorbidity index, response to erythropoiesis-stimulating agents, and transfusion burden
Serum LDH, beta-2 microglobulin, albumin, renal function, and number of cytopenias

Correct answer: Cytogenetic risk group, bone marrow blast percentage, hemoglobin, platelet count, and absolute neutrophil count

The IPSS-R incorporates five variables: cytogenetic risk category (5 groups), bone marrow blast percentage, hemoglobin level, platelet count, and absolute neutrophil count to assign one of five risk categories (Very Low to Very High).

Question 146: A bone marrow biopsy is required to complete staging for which of the following cancers?

Multiple myeloma (Correct answer)
Stage I endometrial cancer
Localized prostate cancer (PSA < 10, Gleason 6)
Stage II non-small cell lung cancer

Correct answer: Multiple myeloma

Bone marrow biopsy is an essential diagnostic and staging tool for multiple myeloma (and other plasma cell dyscrasias), as plasma cell percentage in the marrow is a diagnostic criterion and prognostic factor per IMWG criteria. Lung, prostate, and endometrial cancers at the stages described do not routinely require bone marrow evaluation as part of standard staging workup.

Question 147: A patient on capecitabine develops palmar-plantar erythrodysesthesia (hand-foot syndrome). Which management strategy is most appropriate?

Continue capecitabine without change and monitor weekly
Discontinue capecitabine permanently
Dose reduce capecitabine and initiate pyridoxine and urea-based cream (Correct answer)
Switch to IV 5-fluorouracil immediately

Correct answer: Dose reduce capecitabine and initiate pyridoxine and urea-based cream

Grade 2-3 hand-foot syndrome requires capecitabine dose reduction, with supportive care including pyridoxine and emollient creams.

Question 148: A patient with a known brain metastasis develops sudden-onset severe headache, vomiting, and altered consciousness. What is the priority intervention?

Dexamethasone IV and urgent CT head (Correct answer)
Oral analgesics and observation
Lumbar puncture
Antiemetics alone

Correct answer: Dexamethasone IV and urgent CT head

Increased intracranial pressure from cerebral herniation requires immediate dexamethasone to reduce edema and urgent imaging to guide further management.

Question 149: Opioid rotation is indicated when a patient experiences:

Solely when insurance requires a generic
Inadequate analgesia or intolerable side effects despite dose optimization (Correct answer)
Any mild side effect within 24 hours
Only when switching from oral to IV route

Correct answer: Inadequate analgesia or intolerable side effects despite dose optimization

Opioid rotation is indicated for inadequate pain control or unmanageable adverse effects, exploiting incomplete cross-tolerance to achieve a better balance.

Question 150: A patient with SCLC and SIADH has a serum sodium of 115 mEq/L with severe neurological symptoms (seizures). What is the appropriate rate of sodium correction?

Increase sodium by 20 mEq/L in the first 4 hours
Correct sodium at any rate needed to stop seizures
Maintain correction below 5 mEq/L per 24 hours to avoid rebound
Increase sodium by no more than 8-10 mEq/L per 24 hours (Correct answer)

Correct answer: Increase sodium by no more than 8-10 mEq/L per 24 hours

The safe rate of sodium correction is ≤8-10 mEq/L per 24 hours (up to 1-2 mEq/L/hr in acute symptomatic cases) to prevent osmotic demyelination syndrome while managing neurological symptoms.

Question 151: Which antiemetic is most appropriate for opioid-induced nausea acting via the chemoreceptor trigger zone?

Ondansetron
Prochlorperazine (Correct answer)
Metoclopramide
Dexamethasone

Correct answer: Prochlorperazine

Prochlorperazine (a dopamine antagonist) acts on the chemoreceptor trigger zone (CTZ), which is the primary mechanism of opioid-induced nausea.

Question 152: In febrile neutropenia, an absolute neutrophil count (ANC) below which threshold defines high-risk neutropenia?

< 1500 cells/mm³
< 500 cells/mm³ (Correct answer)
< 1000 cells/mm³
< 2000 cells/mm³

Correct answer: < 500 cells/mm³

An ANC < 500 cells/mm³ (or < 1000 with predicted decline to < 500) defines high-risk neutropenia requiring prompt empiric antibiotics.

Question 153: Compassionate use (expanded access) allows patients outside a clinical trial to receive an investigational drug when:

The patient specifically requests to pay out-of-pocket for the drug
The drug has completed all Phase III trial requirements
The patient has a serious or life-threatening condition with no satisfactory alternatives and cannot enroll in the trial (Correct answer)
The drug has been approved in another country

Correct answer: The patient has a serious or life-threatening condition with no satisfactory alternatives and cannot enroll in the trial

FDA's expanded access (compassionate use) program allows patients with serious or immediately life-threatening conditions to access investigational drugs outside of clinical trials when: (1) no comparable alternatives exist, (2) the patient cannot participate in the clinical trial, (3) potential benefit justifies risk, and (4) access will not interfere with trial completion.

Question 154: The MASCC score is used to stratify risk in which oncologic condition?

Spinal cord compression
Febrile neutropenia (Correct answer)
Tumor lysis syndrome
Hypercalcemia of malignancy

Correct answer: Febrile neutropenia

The Multinational Association for Supportive Care in Cancer (MASCC) score identifies low-risk febrile neutropenia patients who may be managed with oral antibiotics outpatient.

Question 155: Under the Oncology Nursing Society's (ONS) standards, which activity falls within the established scope of practice for an AOCNP in most states?

Independently performing surgical resection of a tumor without physician oversight
Performing bone marrow transplant procedures without oversight
Prescribing chemotherapy regimens within a collaborative practice model (Correct answer)
Interpreting and reporting pathology slides independently

Correct answer: Prescribing chemotherapy regimens within a collaborative practice model

AOCNPs practice within advanced practice registered nurse (APRN) scope, which in most states includes independent or collaborative prescribing of medications, including chemotherapy, within an established oncology practice framework and collaborative agreements where required. Surgical procedures, pathology interpretation, and transplant procedures fall within physician (surgeon, pathologist, transplant physician) scope of practice and are not within NP scope regardless of certification.

Question 156: A Pap smear result of ASC-H (atypical squamous cells, cannot exclude HSIL) in a 35-year-old woman should prompt which next step?

Repeat Pap smear in 12 months
HPV co-testing only
No further evaluation needed
Referral for colposcopy (Correct answer)

Correct answer: Referral for colposcopy

ASC-H (atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion) carries a significant risk of CIN 2/3 and requires immediate colposcopy regardless of HPV status, per ASCCP guidelines.

Question 157: Which serum tumor marker, when significantly elevated at diagnosis of a testicular mass, is most specific for non-seminomatous germ cell tumors (NSGCTs)?

CEA (carcinoembryonic antigen)
AFP (alpha-fetoprotein) (Correct answer)
CA-125
PSA (prostate-specific antigen)

Correct answer: AFP (alpha-fetoprotein)

AFP is characteristically elevated in non-seminomatous germ cell tumors (embryonal carcinoma, yolk sac tumor) and is not produced by pure seminomas. Its elevation helps differentiate NSGCT from pure seminoma, which is critical because treatment approaches differ. CA-125 is used for ovarian cancer. PSA for prostate cancer. CEA is a non-specific marker used in colorectal, lung, and breast cancers.

Question 158: A nurse is educating a patient about the purpose of daily image-guided radiation therapy (IGRT) before each treatment fraction. Which explanation is most accurate?

IGRT replaces the need for immobilization devices by tracking motion in real time
IGRT is used only for brain tumors to achieve stereotactic precision
IGRT uses daily imaging to verify tumor and organ position and adjust treatment delivery for accuracy (Correct answer)
IGRT delivers a higher dose per fraction to shorten overall treatment time

Correct answer: IGRT uses daily imaging to verify tumor and organ position and adjust treatment delivery for accuracy

IGRT acquires images immediately before or during treatment to detect and correct for positional variations, ensuring the radiation dose is delivered accurately to the target.

Question 159: Which dietary recommendation is appropriate for a patient with chemotherapy-induced mucositis?

Suggest citrus juices for vitamin C
Recommend carbonated beverages to maintain hydration
Encourage spicy foods to stimulate taste
Offer soft, bland, moist foods at room temperature (Correct answer)

Correct answer: Offer soft, bland, moist foods at room temperature

Soft, bland, moist foods at room temperature minimize mucosal irritation and are best tolerated during mucositis.

Question 160: What is the most appropriate route of opioid administration for a cancer patient who can no longer swallow and has uncontrolled pain at home?

Intramuscular injection
Rectal suppository
Subcutaneous infusion via syringe driver (Correct answer)
Intravenous bolus in the ED

Correct answer: Subcutaneous infusion via syringe driver

Subcutaneous infusion via a syringe driver provides continuous pain control for patients who cannot swallow, and is well tolerated at home.

Question 161: Which statement correctly describes the principle of double effect in palliative care?

An action with both a beneficial and harmful effect is permissible if the intent is the beneficial effect (Correct answer)
Only nurses can invoke double effect principles
Symptom control must be withheld if it may cause respiratory depression
Any drug that may shorten life is unethical

Correct answer: An action with both a beneficial and harmful effect is permissible if the intent is the beneficial effect

The principle of double effect allows administration of analgesics or sedatives where the intent is symptom relief even if a foreseeable, unintended consequence is hastening death.

Question 162: In a patient with febrile neutropenia and an absolute neutrophil count (ANC) of 400 cells/µL, which scenario mandates inpatient hospitalization and IV antibiotics rather than outpatient oral therapy?

Patient has active pneumonia and hypotension (Correct answer)
Patient has controlled diabetes and lives 20 minutes from the hospital
Patient has a MASCC score of 22
Patient reports mild nausea but is able to swallow pills

Correct answer: Patient has active pneumonia and hypotension

Active pneumonia with hemodynamic instability (hypotension) indicates high-risk febrile neutropenia requiring immediate inpatient IV antibiotics; a MASCC score ≥21 supports low-risk outpatient management.

Question 163: Which opioid is considered first-line for moderate-to-severe cancer pain according to the WHO analgesic ladder?

Codeine
Tramadol
Acetaminophen
Morphine (Correct answer)

Correct answer: Morphine

Morphine remains the WHO-recommended first-line strong opioid for moderate-to-severe cancer pain at Step 3 of the analgesic ladder.

Question 164: Trastuzumab emtansine (T-DM1) is classified as which type of targeted agent?

Checkpoint inhibitor
PARP inhibitor
Antibody-drug conjugate (Correct answer)
CDK4/6 inhibitor

Correct answer: Antibody-drug conjugate

T-DM1 is an antibody-drug conjugate that links trastuzumab to the cytotoxic agent DM1, delivering chemotherapy selectively to HER2-overexpressing cells.

Question 165: When titrating opioids for cancer pain, a patient on oral morphine 60 mg/day has inadequate relief. What is the appropriate dose increase per standard palliative care guidelines?

Increase by 25–33% (Correct answer)
Add a second opioid at the same dose
Double the dose immediately
Increase by 10–15%

Correct answer: Increase by 25–33%

Standard practice recommends increasing the total daily opioid dose by 25–33% when pain is inadequately controlled.

Question 166: Osteoradionecrosis is a late complication of radiation most commonly occurring in which anatomical site?

Lumbar vertebral bodies
Femoral head (hip)
Mandible (jaw) (Correct answer)
Humeral head (shoulder)

Correct answer: Mandible (jaw)

Osteoradionecrosis of the mandible is a severe late radiation complication in patients receiving head and neck radiation. Risk factors include dental extraction in irradiated fields, high cumulative doses, infection, and poor dentition. Prevention includes dental evaluation and extractions before radiation begins.
