AOCNP Oncology Nurse Practitioner Certification Exam — Questions and Answers

Question 1: Which scale is most widely validated for assessing pain intensity in cognitively intact cancer patients?

Numeric Rating Scale (NRS 0–10) (Correct answer)
FLACC scale
CPOT scale
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 2: Which toxicity is specifically associated with VEGFR/multi-kinase inhibitors (sunitinib, sorafenib) and requires proactive management?

Severe neuropathy
Immune-related colitis
Severe anemia
Hand-foot skin reaction (palmar-plantar erythrodysesthesia) (Correct answer)

Correct answer: Hand-foot skin reaction (palmar-plantar erythrodysesthesia)

Hand-foot skin reaction (HFSR/PPE) is a class-specific toxicity of VEGFR TKIs characterized by painful erythema, blistering, and hyperkeratosis on palms and soles. Prevention includes skin moisturization, pressure-relief padding, dose reduction for grade 2–3, and avoidance of tight footwear.

Question 3: A patient develops sudden-onset dyspnea, muffled heart sounds, hypotension, and jugular venous distension. Which emergency is this?

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

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 4: Which dosimetric parameter best predicts the risk of radiation-induced xerostomia when treating head and neck cancer?

Maximum spinal cord dose exceeding 45 Gy
V20 of the larynx exceeding 30%
Mean parotid gland dose exceeding 26 Gy (Correct answer)
Mean mandible dose exceeding 50 Gy

Correct answer: Mean parotid gland dose exceeding 26 Gy

A mean parotid gland dose above 26 Gy is strongly associated with permanent xerostomia in head and neck radiation therapy.

Question 5: Which adaptive trial design feature allows modification of the randomization ratio during an ongoing trial based on interim results?

Response-adaptive randomization (Correct answer)
Parallel-group stratification
Crossover design
Factorial design

Correct answer: Response-adaptive randomization

Response-adaptive randomization dynamically shifts allocation probability toward the better-performing arm as interim data accumulate.

Question 6: The adjuvant treatment for a patient with metastatic renal cell cancer is interleukin-2 (IL-2). The patient is informed by the nurse that the goal of this medication's therapy is to?

Enhance the patient's immunologic response to tumor cells (Correct answer)
Stimulate malignant cells in the resting phase to enter mitosis
Protect normal kidney cells from the damaging effects of chemotherapy
Prevent the bone marrow depression caused by chemotherapy

Correct answer: Enhance the patient's immunologic response to tumor cells

A T-lymphocyte produces IL-2, a naturally occurring protein that helps other white blood cells develop and operate more effectively. This treatment aims to improve the patient's immune system's capacity to control tumor cells.

Question 7: Which intervention is contraindicated in the initial management of SVC syndrome with thrombosis?

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

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

Hyperkalemia
Hypernatremia (Correct answer)
Hypocalcemia
Hyperphosphatemia

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 9: What is the recommended interval for repeat colonoscopy after removal of 3 tubular adenomas <10mm with low-grade dysplasia?

5 years
1 year
10 years
3 years (Correct answer)

Correct answer: 3 years

Current guidelines recommend a 3-year surveillance colonoscopy interval following removal of 3-4 small tubular adenomas with low-grade dysplasia.

Question 10: 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)
Only after completing the full fractionated course (6–10 weeks)
Within 2–4 hours of the first fraction
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 11: Anticipatory grief is best described as:

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

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 12: A 35-year-old with Burkitt lymphoma receives CODOX-M/IVAC chemotherapy. Which prophylactic medication is most critical to prevent a life-threatening metabolic complication?

Rasburicase (Correct answer)
Acyclovir
Fluconazole
Trimethoprim-sulfamethoxazole

Correct answer: Rasburicase

Burkitt lymphoma has an extremely high proliferative rate; rasburicase rapidly degrades uric acid to prevent severe tumor lysis syndrome during induction.

Question 13: A patient receiving pembrolizumab develops severe, grade 3 immune-related pneumonitis. What is the most appropriate initial management?

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

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 14: The BRCA Exchange and NCCN recommend annual MRI screening for BRCA1/2 mutation carriers beginning at what age?

Age 35
Age 25–30 (Correct answer)
Age 40
Age 20

Correct answer: Age 25–30

NCCN recommends annual breast MRI with contrast beginning at age 25–30 for BRCA1/2 carriers and other high-risk individuals. MRI detects occult tumors not visible on mammography due to dense breast tissue common in younger women.

Question 15: Which cancer type is most commonly associated with disseminated intravascular coagulation (DIC) in adults?

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

Correct answer: Acute promyelocytic leukemia (APL)

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

Question 16: Secondary prevention in oncology differs from primary prevention in that secondary prevention focuses on:

Detecting cancer early in asymptomatic individuals (Correct answer)
Preventing recurrence after curative therapy
Reducing risk factors before cancer develops
Treating cancer to prevent metastasis

Correct answer: Detecting cancer early in asymptomatic individuals

Secondary prevention involves early detection of cancer through screening programs in asymptomatic populations, enabling treatment at an earlier, more curable stage. Primary prevention aims to reduce risk factors before cancer occurs.

Question 17: When administering a vesicant chemotherapy agent peripherally, the patient complains of burning and the nurse notes swelling at the IV site. What is the priority intervention?

Remove the IV immediately and apply ice to the site
Stop the infusion immediately, leave the needle in place, and aspirate residual drug (Correct answer)
Flush the line with normal saline and slow the infusion rate
Apply warm compresses and notify the pharmacist

Correct answer: Stop the infusion immediately, leave the needle in place, and aspirate residual drug

The priority is to stop the infusion and leave the needle in place to aspirate residual drug before applying antidote, per extravasation management protocol.

Question 18: The principal long-term complication of radiation to the head and neck that impairs nutrition is:

Peripheral neuropathy
Xerostomia and dysphagia from salivary gland and pharyngeal muscle damage (Correct answer)
Bone marrow suppression
Hepatic fibrosis

Correct answer: Xerostomia and dysphagia from salivary gland and pharyngeal muscle damage

Radiation damages the parotid glands causing permanent dry mouth (xerostomia) and fibroses pharyngeal muscles causing dysphagia, both profoundly affecting nutrition.

Question 19: Radiation-induced secondary malignancy risk is greatest for which patient population?

Adults over 70 years treated for prostate cancer
Patients receiving palliative radiation only
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 20: The HPV vaccine is recommended for which age group as primary prevention against cervical cancer?

Ages 9-12 only
Ages 9-26, with shared decision-making for ages 27-45 (Correct answer)
Ages 13-18 only
Ages 18-45 without restriction

Correct answer: Ages 9-26, with shared decision-making for ages 27-45

HPV vaccine is routinely recommended through age 26; shared clinical decision-making guides vaccination for adults aged 27-45.

Question 21: Which complication is most commonly associated with total gastrectomy for gastric cancer and requires lifelong supplementation?

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

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 22: 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?

Correct sodium at any rate needed to stop seizures
Maintain correction below 5 mEq/L per 24 hours to avoid rebound
Increase sodium by 20 mEq/L in the first 4 hours
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 23: Which sentinel lymph node biopsy technique uses a combination of radioisotope and blue dye to achieve the highest identification rate in breast cancer surgery?

Radioisotope alone injected peritumorally
Dual-agent technique combining radioisotope and blue dye (Correct answer)
Blue dye alone injected subdermally
Indocyanine green fluorescence alone

Correct answer: Dual-agent technique combining radioisotope and blue dye

The dual-agent technique combining radiolabeled colloid and blue dye achieves sentinel node identification rates exceeding 95%, superior to either agent used alone.

Question 24: A patient with cancer-related dyspnea refractory to oxygen is best treated with:

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

Correct answer: Low-dose opioids

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

Question 25: A patient with lung cancer develops facial plethora, arm edema, and distended neck veins. Which imaging study is the priority?

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

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

Platelet count below 75,000/mm³
Platelet count below 10,000/mm³ (Correct answer)
Platelet count below 100,000/mm³
Platelet count below 50,000/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 27: Which non-pharmacological intervention has the strongest evidence for reducing cancer-related fatigue?

Prolonged bed rest
Vitamin C supplementation
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 28: Nine days after chemotherapy, a 36-year-old cancer patient exhibits warning signs of impending septic shock. Which of the following would the nurse anticipate to be present?

Flushing, decreased oxygen saturation, mild hypotension
Elevated temperature, oliguria, hypotension
High-grade fever, normal blood pressure, increased respirations
Low-grade fever, chills, tachycardia (Correct answer)

Correct answer: Low-grade fever, chills, tachycardia

One would anticipate that the patient will have compromised immunity nine days following chemotherapy. Changes in heart function, vascular resistance, cellular metabolism, and capillary permeability are reflected in the clinical manifestations of shock. Tachycardia, flushing, and a low-grade temperature could be the first indications of shock.

Question 29: Checkpoint inhibitors targeting PD-1 (e.g., pembrolizumab) cause a distinctive class of toxicities called:

Cytokine release syndrome
Infusion-related reactions only
Tumor lysis syndrome
Immune-related adverse events (irAEs) (Correct answer)

Correct answer: Immune-related adverse events (irAEs)

By unleashing T-cell activity, PD-1 inhibitors can cause immune-related adverse events across any organ, including colitis, pneumonitis, hepatitis, and endocrinopathies.

Question 30: Radiation recall is defined as:

Erythema appearing during radiation fractions
Inflammatory reaction at a prior radiation site triggered by a systemic drug (Correct answer)
Skin reaction from a second radiation course to the same site
Fatigue persisting after radiation is completed

Correct answer: Inflammatory reaction at a prior radiation site triggered by a systemic drug

Radiation recall is a cutaneous or mucosal inflammatory reaction at a previously irradiated field, triggered by a systemic agent (commonly anthracyclines or taxanes) administered after radiation.

Question 31: An NP notes that a published RCT has a high attrition rate with differential dropout between arms. Which type of bias is most concerning?

Attrition bias (Correct answer)
Detection bias
Selection bias
Performance bias

Correct answer: Attrition bias

Attrition bias occurs when differential or substantial loss to follow-up between arms distorts the comparison of outcomes.

Question 32: Which electrolyte imbalance is most commonly seen with severe radiation-induced mucositis and diarrhea?

Hypokalemia, hypomagnesemia, and hyponatremia (Correct answer)
Hypermagnesemia
Hypercalcemia
Hyperkalemia and hypernatremia

Correct answer: Hypokalemia, hypomagnesemia, and hyponatremia

Severe mucositis and radiation enteritis/diarrhea cause significant electrolyte losses, particularly potassium, magnesium, and sodium. These deficiencies require close monitoring and replacement to prevent cardiac arrhythmias and neuromuscular complications.

Question 33: Which medication is first-line for neuropathic pain in cancer patients?

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

Correct answer: Gabapentin or pregabalin

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

Question 34: Which first-line intervention is indicated for hypercalcemia of malignancy with corrected serum calcium > 14 mg/dL?

Furosemide alone
Oral calcitonin
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 35: A patient who received mantle field radiation for Hodgkin lymphoma 20 years ago is now diagnosed with coronary artery disease at age 42. This represents which category of late radiation effect?

Pericarditis constrictiva
Radiation-induced cardiomyopathy
Accelerated atherosclerosis as a radiation late effect (Correct answer)
Secondary malignancy

Correct answer: Accelerated atherosclerosis as a radiation late effect

Mediastinal radiation accelerates atherosclerosis in the coronary arteries, leading to premature coronary artery disease in Hodgkin lymphoma survivors, a well-recognized late cardiovascular toxicity.

Question 36: Which statement about neutropenic enterocolitis (typhlitis) in oncology patients is CORRECT?

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

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 37: 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)
Any drug that may shorten life is unethical
Only nurses can invoke double effect principles
Symptom control must be withheld if it may cause respiratory depression

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 38: Which paraneoplastic syndrome is most commonly associated with small cell lung cancer?

Dermatomyositis
Hypercalcemia of malignancy
Syndrome of inappropriate antidiuretic hormone (SIADH) (Correct answer)
Polycythemia

Correct answer: Syndrome of inappropriate antidiuretic hormone (SIADH)

SIADH, caused by ectopic ADH production, is the most common paraneoplastic syndrome associated with small cell lung cancer.

Question 39: A patient with polycythemia vera (PV) develops a new stroke. Which mutation drives the majority of PV cases and is used for diagnosis?

CALR exon 9
BCR-ABL1
MPL W515L
JAK2 V617F (Correct answer)

Correct answer: JAK2 V617F

JAK2 V617F is present in >95% of PV cases and is central to the 2016 WHO diagnostic criteria.

Question 40: A female cancer survivor treated with cyclophosphamide-based chemotherapy reports amenorrhea and hot flashes. These symptoms are most likely related to:

Adrenal insufficiency from chemotherapy
Premature ovarian insufficiency (POI) / chemotherapy-induced menopause (Correct answer)
Paraneoplastic syndrome
Hypothyroidism from radiation scatter

Correct answer: Premature ovarian insufficiency (POI) / chemotherapy-induced menopause

Alkylating agents (cyclophosphamide, ifosfamide) and platinum compounds are the most gonadotoxic chemotherapy drugs, causing premature ovarian insufficiency (POI) in premenopausal women through direct destruction of primordial follicles. POI manifests as amenorrhea, vasomotor symptoms, infertility, sexual dysfunction, and accelerated bone loss.

Question 41: A patient with small cell lung cancer presents with hyponatremia (Na 118 mEq/L), concentrated urine, and euvolemia. Which oncologic emergency is most likely?

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

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 42: 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)
Veracity
Justice

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 43: Which biomarker is most predictive of response to olaparib in ovarian cancer?

HER2 amplification
KRAS mutation
PD-L1 expression
BRCA1/2 mutation (Correct answer)

Correct answer: BRCA1/2 mutation

Olaparib is a PARP inhibitor with the strongest efficacy evidence in BRCA1/2-mutated ovarian cancer due to synthetic lethality.

Question 44: Which of the following is the FIRST-LINE treatment for malignant spinal cord compression (MSCC) once the diagnosis is confirmed?

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

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 45: Stereotactic body radiation therapy (SBRT) differs from conventional radiation by delivering:

Radiation through a radioactive implant only
Low doses over many weeks
Very high doses per fraction in a small number of treatments with precise targeting (Correct answer)
Whole-body radiation for systemic disease

Correct answer: Very high doses per fraction in a small number of treatments with precise targeting

SBRT delivers ablative doses (typically 5–20 Gy/fraction) in 1–5 fractions with submillimeter precision, maximizing tumor cell kill while sparing surrounding tissue.

Question 46: A patient with colorectal cancer is found to have a RAS mutation. What is the implication for treatment?

Eligible for cetuximab therapy
Not eligible for anti-EGFR therapy (Correct answer)
Requires immediate surgical resection
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 47: Which biologic agent works by depleting CD20-positive B cells and is used in certain lymphomas?

Rituximab (Correct answer)
Denosumab
Cetuximab
Ramucirumab

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 48: Disseminated intravascular coagulation (DIC) is one of the most dangerous blood coagulation side effects for cancer patients and those receiving cancer therapy. This bleed disorder's most typical cause is:

Intravenous heparin therapy
Sepsis (Correct answer)
Underlying liver disease
Brain metastasis

Correct answer: Sepsis

The Hageman factor, also known as coagulation factor XII, is activated by bacterial endotoxins generated by gram-negative bacteria. By inhibiting coagulation through the homeostasis pathway, this substance also promotes fibrinolysis.

Question 49: Which immune-related adverse event (irAE) is most commonly associated with anti-PD-1/PD-L1 therapy?

Hypothyroidism (Correct answer)
Myocarditis
Pneumonitis
Colitis

Correct answer: Hypothyroidism

Thyroid dysfunction (hypothyroidism more common than hyperthyroidism) is among the most frequent irAEs with anti-PD-1/PD-L1 therapy, occurring in 6–20% of patients. TSH monitoring is recommended at baseline and every 4–6 weeks during treatment.

Question 50: A patient with cervical cancer is receiving concurrent cisplatin and radiation therapy. She reports decreased urine output and her creatinine has risen from 0.9 to 2.4 mg/dL. The BEST immediate intervention is:

Continue cisplatin at a reduced dose of 50%
Administer furosemide to increase urine output
Hold cisplatin, ensure aggressive IV hydration, and consult nephrology (Correct answer)
Switch to carboplatin and continue radiation

Correct answer: Hold cisplatin, ensure aggressive IV hydration, and consult nephrology

Acute cisplatin nephrotoxicity requires immediate drug hold, aggressive IV hydration to restore renal perfusion, and nephrology consultation.

Question 51: Which measurement best indicates that a patient is at high risk of imminent death (hours to days) in the inpatient palliative setting?

Mild confusion in the morning
Refusal of one meal
Decreased urine output, mottling, irregular respirations, and unresponsiveness (Correct answer)
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 52: 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)
Osteoclast activation by bone metastases
Excess 1,25-dihydroxyvitamin D production

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 53: Which toxicity is most specifically associated with bleomycin and requires monitoring with pulmonary function tests?

Pulmonary fibrosis and pneumonitis (Correct answer)
Hepatotoxicity with elevated transaminases
Cardiotoxicity with reduced ejection fraction
Nephrotoxicity with rising creatinine

Correct answer: Pulmonary fibrosis and pneumonitis

Bleomycin causes pulmonary toxicity ranging from pneumonitis to fibrosis, which can be life-threatening and requires baseline and serial PFTs.

Question 54: When converting a patient from IV hydromorphone 1.5 mg/hour continuous infusion to oral extended-release opioids, the nurse practitioner should:

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)
Simply stop IV and start the oral agent at the same numeric dose

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 55: Which of the following describes the pharmacodynamic rationale for using leucovorin (folinic acid) in combination with 5-fluorouracil (5-FU)?

Leucovorin increases 5-FU bioavailability by inhibiting CYP2A6
Leucovorin reduces 5-FU-induced nephrotoxicity
Leucovorin stabilizes the ternary complex of 5-FU with thymidylate synthase, enhancing inhibition (Correct answer)
Leucovorin acts as a rescue agent to prevent 5-FU toxicity

Correct answer: Leucovorin stabilizes the ternary complex of 5-FU with thymidylate synthase, enhancing inhibition

Leucovorin provides reduced folate that stabilizes the ternary complex between FdUMP (5-FU metabolite) and thymidylate synthase, enhancing its cytotoxic effect.

Question 56: In a Phase I clinical trial for a new oncology drug, the primary objective is to determine:

Maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) (Correct answer)
Quality of life improvements over existing therapy
Efficacy and overall response rate
Long-term survival benefit compared to standard of care

Correct answer: Maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs)

Phase I trials are primarily safety/dose-finding studies. The primary objectives are to establish the maximum tolerated dose (MTD), characterize dose-limiting toxicities (DLTs), determine the recommended Phase II dose (RP2D), and describe the pharmacokinetic profile. Efficacy is a secondary/exploratory endpoint.

Question 57: Which serum tumor marker, when significantly elevated at diagnosis of a testicular mass, is most specific for non-seminomatous germ cell tumors (NSGCTs)?

PSA (prostate-specific antigen)
CA-125
AFP (alpha-fetoprotein) (Correct answer)
CEA (carcinoembryonic 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 58: Which grading tool is most appropriate for evaluating chemotherapy-induced peripheral neuropathy (CIPN) severity in clinical oncology practice?

Functional Assessment of Cancer Therapy (FACT-G)
Karnofsky Performance Scale
Eastern Cooperative Oncology Group (ECOG) scale
NCI Common Terminology Criteria for Adverse Events (CTCAE) (Correct answer)

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

The NCI CTCAE provides standardized grading (1–4) for peripheral neuropathy and is the standard tool used in oncology clinical trials and practice.

Question 59: Syndrome of inappropriate antidiuretic hormone secretion (SIADH) in cancer is best managed initially with:

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

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

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

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 61: Which regulatory pathway allows the FDA to approve a cancer drug based on a surrogate endpoint reasonably likely to predict clinical benefit?

Priority review designation
Orphan drug designation
Accelerated approval (Correct answer)
Regular approval

Correct answer: Accelerated approval

Accelerated approval allows use of surrogate or intermediate endpoints (e.g., ORR, PFS) when likely to predict clinical benefit, with confirmatory trials required.

Question 62: A patient with esophageal cancer develops odynophagia and dysphagia during the third week of concurrent chemoradiation. CT shows mucosal thickening of the esophagus without perforation. What is the most appropriate management?

Perform emergent endoscopy and esophageal stenting
Switch to hyperfractionated radiation to reduce acute mucosal dose
Discontinue radiation immediately and restart after 2 weeks
Provide symptomatic management with viscous lidocaine, analgesics, and nutritional support (Correct answer)

Correct answer: Provide symptomatic management with viscous lidocaine, analgesics, and nutritional support

Acute radiation esophagitis is expected during chemoradiation for esophageal cancer and is managed symptomatically with analgesics, mucosal coating agents, and nutritional optimization while continuing treatment.

Question 63: 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 64: R0 resection in surgical oncology means:

Complete resection with negative (clear) surgical margins (Correct answer)
Palliative debulking with gross disease remaining
Resection with intraoperative frozen section only
Residual microscopic disease at the margins

Correct answer: Complete resection with negative (clear) surgical margins

R0 resection indicates microscopically negative surgical margins (no residual tumor), representing the gold standard goal of curative surgery. R1 resection has microscopic positive margins; R2 has macroscopic residual disease. R0 status is a major determinant of recurrence risk and survival.

Question 65: 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?

Double the dose immediately
Increase by 25–33% (Correct answer)
Add a second opioid at the same dose
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 66: 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?

Carboplatin
Vincristine
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 67: A 70-year-old woman asks about cervical cancer screening. Which recommendation is most appropriate for an average-risk woman her age?

Continue annual Pap smears indefinitely
Discontinue screening if she has had adequate prior screening with no abnormal results (Correct answer)
Begin colposcopy surveillance annually
Switch to HPV co-testing every 3 years

Correct answer: Discontinue screening if she has had adequate prior screening with no abnormal results

Women aged 65 and older with adequate prior negative screening can discontinue cervical cancer screening per USPSTF guidelines.

Question 68: Which genetic mutation significantly elevates the lifetime risk of breast and ovarian cancer, prompting enhanced surveillance protocols?

MLH1/MSH2
TP53 only
BRCA1/BRCA2 (Correct answer)
APC gene

Correct answer: BRCA1/BRCA2

Pathogenic variants in BRCA1 and BRCA2 genes confer a lifetime breast cancer risk of 50–72% and ovarian cancer risk of 17–44%. Carriers require enhanced screening including annual MRI and mammography beginning at age 25–30.

Question 69: Which prognostic tool is validated to estimate survival in weeks to months for palliative care patients?

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

Correct answer: Palliative Performance Scale (PPS)

Caprini score
APACHE II score
POSSUM score
ARISCAT score (Correct answer)

Correct answer: ARISCAT score

The ARISCAT (Assess Respiratory Risk in Surgical Patients in Catalonia) score predicts postoperative pulmonary complications and guides risk stratification for surgical patients.

Question 71: Which HPV strains are considered high-risk and are most commonly associated with cervical cancer?

HPV 2 and 4
HPV 6 and 11
HPV 16 and 18 (Correct answer)
HPV 31 and 45 only

Correct answer: HPV 16 and 18

HPV types 16 and 18 are the most oncogenic high-risk strains, responsible for approximately 70% of cervical cancers and a significant proportion of oropharyngeal, anal, vulvar, vaginal, and penile cancers.

Question 72: A patient with ovarian cancer has completed platinum-based chemotherapy and achieved complete response. She carries a BRCA1 mutation. What is the recommended maintenance therapy?

Tamoxifen
Lenalidomide
Olaparib (PARP inhibitor) (Correct answer)
Bevacizumab monotherapy

Correct answer: Olaparib (PARP inhibitor)

Olaparib maintenance is recommended for BRCA-mutated ovarian cancer after response to platinum-based chemotherapy, significantly prolonging progression-free survival.

Question 73: 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 a MASCC score of 22
Patient has controlled diabetes and lives 20 minutes from the hospital
Patient reports mild nausea but is able to swallow pills
Patient has active pneumonia and hypotension (Correct answer)

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

Bevacizumab
Imatinib
Trastuzumab (Correct answer)
Erlotinib

Correct answer: Trastuzumab

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

Question 75: 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)
Duration of neurological symptoms less than 24 hours
Sensitivity of the underlying malignancy to radiation
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 76: Which ethical principle is most prominently invoked when an oncology NP advocates for a patient's right to refuse further chemotherapy despite family pressure to continue treatment?

Justice
Beneficence
Autonomy (Correct answer)
Non-maleficence

Correct answer: Autonomy

Autonomy — the right of a competent individual to make decisions about their own body and care without coercion — is the core principle at stake when honoring a patient's informed refusal of treatment. Beneficence refers to acting in the patient's best interest. Non-maleficence means avoiding harm. Justice involves fair distribution of resources. Advocacy for a patient's treatment refusal against external pressure is a classic application of respecting autonomy.

Question 77: An AOCNP is counseling the family of a dying patient about the 'death rattle.' Which statement is most accurate?

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

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

Acetaminophen
Morphine (Correct answer)
Tramadol
Codeine

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 79: Palliative sedation is ethically appropriate when:

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

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 80: What is the recommended duration of anticoagulation for cancer-associated venous thromboembolism (VTE)?

At least 6 months with continuation as long as cancer is active (Correct answer)
6 months then reassess
3 months then discontinue
Lifelong anticoagulation regardless of disease status

Correct answer: At least 6 months with continuation as long as cancer is active

Guidelines recommend at least 6 months of anticoagulation for cancer-associated VTE, with continuation as long as the cancer remains active or treatment is ongoing.

Question 81: 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:

Peer support groups only
Long-term benzodiazepine therapy
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 82: Which taxane is approved for albumin-bound nanoparticle formulation to reduce hypersensitivity and improve delivery?

Docetaxel
Nab-paclitaxel (Abraxane) (Correct answer)
Ixabepilone
Cabazitaxel

Correct answer: Nab-paclitaxel (Abraxane)

Nab-paclitaxel encapsulates paclitaxel in albumin nanoparticles, eliminating the Cremophor solvent that causes hypersensitivity reactions.

Question 83: Which grading scale is most widely used to classify chemotherapy-induced adverse effects in clinical oncology practice?

Karnofsky Performance Scale
Eastern Cooperative Oncology Group (ECOG) scale
Numerical Rating Scale (NRS)
NCI Common Terminology Criteria for Adverse Events (CTCAE) (Correct answer)

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

The NCI CTCAE is the standardized tool used in oncology to grade the severity (grades 1–5) of treatment-related adverse events.

Question 84: Secondary malignancy risk is particularly elevated in survivors who received which type of treatment?

Hormonal therapy with tamoxifen only
Anti-HER2 therapy
Alkylating agents and/or radiation therapy, which increase risk of therapy-related MDS/AML and solid tumors (Correct answer)
Immunotherapy checkpoint inhibitors

Correct answer: Alkylating agents and/or radiation therapy, which increase risk of therapy-related MDS/AML and solid tumors

Alkylating agents (cyclophosphamide, nitrogen mustard, melphalan) and topoisomerase II inhibitors cause therapy-related myelodysplastic syndrome (t-MDS) and acute myeloid leukemia (t-AML). Radiation exposure increases risk of secondary solid tumors in the radiation field (sarcoma, breast cancer after chest RT, lung cancer). Lifelong surveillance is essential.

Question 85: Superior vena cava (SVC) syndrome with acute airway compromise and cerebral edema should be treated FIRST with which intervention?

High-dose systemic corticosteroids alone
Emergent SVC stenting or radiation therapy (Correct answer)
Surgical bypass grafting of the SVC
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 86: When a patient with liver cancer who is receiving home care from family members says, "I have intense pain most of the time now," the nurse knows that her pain management education has been successful.

Uses the ordered opioid pain medication whenever the pain is greater than 5 on a 10-point scale
States that nonopioid analgesics may be used when the maximal dose of the opioid is reached without adequate pain relief
Takes opioids around the clock on a regular schedule and uses additional doses when breakthrough pain occurs (Correct answer)
Agrees to take the medications by the IV route to improve effectiveness

Correct answer: Takes opioids around the clock on a regular schedule and uses additional doses when breakthrough pain occurs

Analgesics for cancer pain should be given regularly with additional dosages as needed for pain flare-ups.

Question 87: The MASCC score is used to stratify risk in which oncologic condition?

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

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 88: 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?

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

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

Rasburicase
Allopurinol (Correct answer)
Sodium bicarbonate
Hydroxyurea

Correct answer: Allopurinol

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

Question 90: 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
Oral calcium supplements to recalibrate serum levels
Intravenous bisphosphonate such as zoledronic acid after IV hydration (Correct answer)
Subcutaneous calcitonin as the sole long-term agent

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 91: Prophylactic cranial irradiation (PCI) is standard of care for which cancer type to reduce the risk of brain metastases?

Glioblastoma multiforme
Stage III breast cancer
Locally advanced non-small cell lung cancer
Limited-stage small cell lung cancer in complete response (Correct answer)

Correct answer: Limited-stage small cell lung cancer in complete response

PCI is standard of care for patients with limited-stage SCLC who achieve complete response to initial chemoradiation, as the brain is a common sanctuary site. PCI reduces the incidence of brain metastases and improves overall survival in this population.

Question 92: Which biomarker must be tested before initiating trastuzumab (Herceptin) therapy for breast cancer?

KRAS mutation status
PD-L1 expression level
EGFR mutation
HER2 overexpression or gene amplification (Correct answer)

Correct answer: HER2 overexpression or gene amplification

Trastuzumab targets the HER2 (human epidermal growth factor receptor 2) protein. HER2 testing by IHC (3+ overexpression) and/or FISH/ISH (gene amplification) is mandatory before initiating trastuzumab, as it is only effective in HER2-positive tumors (~15–20% of breast cancers).

Question 93: 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)
Hypersensitivity anaphylaxis
Venous thrombosis of mesenteric vessels
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 94: A patient with malignant bowel obstruction is not a surgical candidate. Which combination is most appropriate for symptom management?

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

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 95: The BRCA1/2 mutation confers the highest lifetime risk for which two cancers?

Breast and lung cancer
Ovarian and pancreatic cancer
Breast and colon cancer
Breast and ovarian cancer (Correct answer)

Correct answer: Breast and ovarian cancer

BRCA1/2 mutations confer a lifetime breast cancer risk of 50–80% and ovarian cancer risk of 15–44%, with BRCA1 conferring the highest ovarian risk.

Question 96: Which laxative regimen should ALWAYS accompany opioid therapy to prevent constipation?

A stimulant laxative such as senna (Correct answer)
Osmotic laxatives only as needed
High-fiber diet alone
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 97: Which tool is specifically validated for assessing symptom burden in patients with advanced cancer across multiple symptom domains?

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

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 98: Statistical significance (p < 0.05) in an oncology trial means:

The probability that the observed result occurred by chance alone is less than 5% (Correct answer)
The treatment effect is clinically meaningful and important
The therapy is superior to all existing treatments
The trial was adequately powered to detect any difference

Correct answer: The probability that the observed result occurred by chance alone is less than 5%

A p-value <0.05 indicates that if the null hypothesis (no treatment difference) were true, the probability of observing results as extreme or more extreme is <5% — a conventional threshold for rejecting the null hypothesis. Statistical significance does NOT equate to clinical significance; effect size and clinical context must also be evaluated.

Question 99: 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)
Thrombotic thrombocytopenic purpura (TTP)
Immune thrombocytopenic purpura (ITP)

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 100: A patient with diffuse large B-cell lymphoma on R-CHOP develops a fever of 38.5°C on day 10 post-chemotherapy with an ANC of 200 cells/µL. According to MASCC criteria, what is the PRIORITY action?

Order blood cultures and begin empiric broad-spectrum IV antibiotics within 1 hour (Correct answer)
Wait for culture results before starting antibiotics
Prescribe oral ciprofloxacin and levofloxacin and discharge home
Administer G-CSF and recheck ANC in 24 hours before starting antibiotics

Correct answer: Order blood cultures and begin empiric broad-spectrum IV antibiotics within 1 hour

Febrile neutropenia (ANC <500 with fever ≥38.3°C) requires blood cultures and empiric broad-spectrum IV antibiotics within 60 minutes of presentation.

Question 101: Which action is central to the NURSE communication framework used in delivering serious news to cancer patients?

Notifying the family before the patient
Naming, understanding, respecting, supporting, and exploring emotions (Correct answer)
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 102: 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 has not yet invaded beyond the basement membrane
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 closely resembles normal tissue and likely grows slowly

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 103: A male patient with metastatic castration-resistant prostate cancer has progressed on enzalutamide. BRCA2 mutation is confirmed. What is the next preferred therapy?

Sipuleucel-T
Cabazitaxel
Olaparib (Correct answer)
Radium-223

Correct answer: Olaparib

Olaparib, a PARP inhibitor, is approved for BRCA-mutated metastatic castration-resistant prostate cancer after progression on enzalutamide or abiraterone.

Question 104: The linear-quadratic model is used in radiation oncology to calculate which of the following?

Patient eligibility for clinical trials
Chemotherapy dose adjustments based on creatinine clearance
Radiation field size for skin cancers
Biologically effective dose (BED) when comparing different fractionation schedules (Correct answer)

Correct answer: Biologically effective dose (BED) when comparing different fractionation schedules

The linear-quadratic (LQ) model calculates the BED to compare the biological equivalence of different fractionation schedules. The α/β ratio characterizes tissue sensitivity — late-reacting tissues (α/β ~3 Gy) are more sensitive to large fractions, while tumors and early-responding tissues (α/β ~10 Gy) are less so.

Question 105: 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?

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

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 106: The primary tool used to formally screen cancer survivors for distress at regular intervals is:

The SF-36 Health Survey
The NCCN Distress Thermometer and Problem List (Correct answer)
The PHQ-9 (Patient Health Questionnaire-9)
The Hamilton Anxiety Rating Scale

Correct answer: The NCCN Distress Thermometer and Problem List

The NCCN Distress Thermometer (DT) with the accompanying Problem List is the most widely used validated rapid distress screening tool in oncology. A score ≥4 on the 0–10 scale indicates clinically significant distress warranting psychosocial evaluation. It screens across practical, family, emotional, spiritual, and physical domains.

Question 107: Which skin care instruction is correct for patients undergoing external beam radiation therapy to the breast?

Apply petroleum-based thick ointments within 4 hours before each treatment
Shave the axilla with a straight razor throughout treatment
Avoid tight clothing, heat, and sun exposure; use gentle fragrance-free moisturizers (Correct answer)
Use alcohol-based antiseptic washes on the treated area daily

Correct answer: Avoid tight clothing, heat, and sun exposure; use gentle fragrance-free moisturizers

Protecting irradiated skin from friction, heat, and UV while maintaining moisture with gentle products reduces the severity of radiation dermatitis.

Question 108: The ONCO NP is educating a patient beginning osimertinib. Which side effect is most important to monitor and manage proactively?

Severe cytokine release syndrome
Grade 3–4 mucositis
Dermatologic toxicity and QTc prolongation (Correct answer)
Severe hemorrhagic cystitis

Correct answer: Dermatologic toxicity and QTc prolongation

Osimertinib commonly causes acneiform rash, dry skin, paronychia, and can cause QTc prolongation (interstitial lung disease is a rare but serious toxicity). Baseline and periodic ECG monitoring is recommended; dermatologic prophylaxis with topical antibiotics and emollients is standard practice.

Question 109: What is the preferred initial antibiotic for low-risk febrile neutropenia being managed outpatient?

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

Correct answer: Ciprofloxacin plus amoxicillin-clavulanate

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

Question 110: 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 111: The Edmonton Symptom Assessment System (ESAS) measures which of the following?

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

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 112: A patient undergoing prostate brachytherapy with permanent iodine-125 seeds is being discharged. Which instruction is most important?

Avoid sexual activity permanently following seed implantation
Stay in the hospital for 72 hours until seeds lose all radioactivity
Wear a lead apron at all times when around other people
Avoid prolonged close contact with pregnant women and young children for several months (Correct answer)

Correct answer: Avoid prolonged close contact with pregnant women and young children for several months

I-125 seeds emit low-energy photons for months; precautions include limiting prolonged close contact with pregnant women and children, though risk to others is low.

Question 113: A patient with head and neck cancer develops trismus 8 months after completing chemoradiation. Which structure's fibrosis most directly causes this complication?

Temporomandibular joint and masticatory muscles (Correct answer)
Parotid glands
Cervical lymph nodes
Submandibular glands

Correct answer: Temporomandibular joint and masticatory muscles

Trismus results from radiation-induced fibrosis of the masticatory muscles and temporomandibular joint, causing limited mouth opening.

Question 114: Which electrolyte abnormality most immediately threatens cardiac function in tumor lysis syndrome?

Hyperphosphatemia
Hyperkalemia (Correct answer)
Hyperuricemia
Hypocalcemia

Correct answer: Hyperkalemia

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

Question 115: Which nursing intervention is most important for patients receiving pelvic radiation to prevent vaginal stenosis?

Use of vaginal dilators beginning 2–4 weeks after radiation completion (Correct answer)
Avoid all pelvic examinations until 1 year post-treatment
Topical estrogen cream daily throughout treatment
Pelvic floor physical therapy starting on day 1 of radiation

Correct answer: Use of vaginal dilators beginning 2–4 weeks after radiation completion

Vaginal dilators are recommended beginning 2–4 weeks after pelvic radiation completion (or sooner as tolerated) to prevent fibrosis and stenosis. Regular sexual activity or dilator use maintains vaginal patency and reduces scar tissue formation, preserving quality of life and facilitating follow-up gynecologic exams.

Question 116: A patient with multiple myeloma is at greatest risk for which skeletal complication?

Pathological fractures due to osteolytic lesions (Correct answer)
Osteoblastic lesions causing bone sclerosis
Avascular necrosis of the femoral head
Osteosarcoma of the long bones

Correct answer: Pathological fractures due to osteolytic lesions

Multiple myeloma causes osteolytic (bone-destroying) lesions that significantly weaken bone structure, increasing the risk of pathological fractures.

Question 117: 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 laboratory's accreditation status
The turnaround time for results
The cost of the genomic test and insurance coverage
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 118: A bone marrow biopsy is required to complete staging for which of the following cancers?

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

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 119: When performing intraoperative frozen section analysis of surgical margins in a patient with oral cavity squamous cell carcinoma, a finding of 'close margin' (<1mm) should prompt the surgeon to:

Abort the procedure and plan re-excision at a later date
Proceed with closure and plan adjuvant radiation
Accept the margin and increase chemotherapy dosing postoperatively
Take additional tissue to achieve clear margins intraoperatively (Correct answer)

Correct answer: Take additional tissue to achieve clear margins intraoperatively

Intraoperative frozen section provides real-time guidance, and close or positive margins should be addressed immediately by re-excision to optimize local control.

Question 120: Which statistical concept describes the probability of correctly detecting a true treatment effect in a clinical trial?

P-value threshold
Statistical power (Correct answer)
Confidence interval width
Type I error

Correct answer: Statistical power

Statistical power (1 − β) is the probability that a trial will detect a true treatment effect when one exists.

Question 121: All of these symptoms are reported by a patient who is getting interleukin-2 (IL-2) therapy (Proleukin). Which one needs to be reported to the healthcare provider first?

Generalized aches
Dyspnea (Correct answer)
Insomnia
Decreased appetite

Correct answer: Dyspnea

Dyspnea may be a sign of pulmonary edema and capillary leak syndrome, both of which need prompt medical attention.

Question 122: Which hereditary cancer syndrome is characterized by mismatch repair (MMR) gene mutations and confers a markedly elevated lifetime risk of colorectal and endometrial cancers?

Li-Fraumeni syndrome
Lynch syndrome (Hereditary Nonpolyposis Colorectal Cancer) (Correct answer)
Cowden syndrome
Familial adenomatous polyposis (FAP)

Correct answer: Lynch syndrome (Hereditary Nonpolyposis Colorectal Cancer)

Lynch syndrome is caused by germline mutations in MMR genes (MLH1, MSH2, MSH6, PMS2) and accounts for the most common hereditary colorectal cancer syndrome. Lifetime colorectal cancer risk can reach 80% and endometrial cancer risk 40–60%. FAP involves APC mutations and thousands of polyps. Li-Fraumeni involves TP53. Cowden involves PTEN and thyroid/breast risk.

Question 123: The PSA screening recommendation for prostate cancer emphasizes:

Shared decision-making with men aged 55–69 after discussing benefits and harms (Correct answer)
Routine screening of all men over 70
Universal annual screening for all men over 40
No PSA testing under any circumstances

Correct answer: Shared decision-making with men aged 55–69 after discussing benefits and harms

USPSTF and ACS guidelines emphasize individualized shared decision-making for men aged 55–69, acknowledging the benefit of early detection versus overdiagnosis and overtreatment harms.

Question 124: Radiation-induced xerostomia (dry mouth) is most effectively prevented by which technique when treating head and neck cancers?

Amifostine premedication before every fraction
Reducing the total radiation dose below 30 Gy
Using brachytherapy for all head and neck cancers
Intensity-modulated radiation therapy (IMRT) with parotid gland sparing (Correct answer)

Correct answer: Intensity-modulated radiation therapy (IMRT) with parotid gland sparing

IMRT allows dose sculpting that significantly spares the parotid glands (mean dose <26 Gy), substantially reducing the incidence and severity of permanent xerostomia compared to conventional 3D-conformal techniques. Amifostine has modest benefit and significant toxicity.

Question 125: 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)
Erythropoiesis-stimulating agents
High-dose multivitamin supplementation
Metformin

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 126: "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:

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

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 127: 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 128: A patient receiving cisplatin-based chemotherapy develops tinnitus and high-frequency hearing loss. Which intervention is the nurse's priority?

Schedule an audiologist referral for next week
Reassure the patient this is a temporary side effect
Notify the oncologist immediately and document findings (Correct answer)
Administer amifostine as ordered

Correct answer: Notify the oncologist immediately and document findings

Ototoxicity is a serious cisplatin toxicity that should be promptly reported to the oncologist as it may require dose modification or discontinuation.

Question 129: 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?

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

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 130: A patient taking tamoxifen for hormone receptor-positive breast cancer asks about side effects. Which response is most accurate?

'Tamoxifen has no significant side effects since it is not chemotherapy.'
'Tamoxifen increases the risk of endometrial cancer, blood clots, and hot flashes.' (Correct answer)
'The main side effect is hair loss and immunosuppression.'
'You will need monthly blood transfusions while on this medication.'

Correct answer: 'Tamoxifen increases the risk of endometrial cancer, blood clots, and hot flashes.'

Tamoxifen's known risks include endometrial cancer, venous thromboembolism, and vasomotor symptoms such as hot flashes due to its mixed estrogenic/antiestrogenic activity.

Question 131: 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 132: Which malignancy is MOST commonly associated with malignant pericardial effusion and cardiac tamponade?

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

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 133: Methylnaltrexone (Relistor) treats opioid-induced constipation by:

Increasing intestinal secretions
Inhibiting serotonin in the gut
Stimulating intestinal smooth muscle directly
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 134: Which imaging finding on MRI spine best confirms malignant spinal cord compression requiring urgent treatment?

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

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 135: A patient is receiving intrathecal methotrexate. Which neurotoxicity symptom requires the nurse to stop the infusion and alert the provider?

Low-grade fever of 37.8°C
Temporary nausea lasting 30 minutes
Sudden leg weakness, bladder dysfunction, and back pain suggesting myelopathy (Correct answer)
Mild headache rated 2/10 immediately post-injection

Correct answer: Sudden leg weakness, bladder dysfunction, and back pain suggesting myelopathy

Signs of myelopathy (leg weakness, bowel/bladder changes) after intrathecal chemotherapy represent a serious neurotoxic complication requiring urgent evaluation.

Question 136: Which antiemetic is most appropriate for opioid-induced nausea acting via the chemoreceptor trigger zone?

Metoclopramide
Ondansetron
Prochlorperazine (Correct answer)
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 137: A patient receiving cisplatin-based chemotherapy develops tinnitus and decreased high-frequency hearing. Which intervention is most appropriate?

Reduce the cisplatin dose by 25% and continue
Document the finding and reassess at the next scheduled visit
Discontinue cisplatin and notify the oncologist immediately (Correct answer)
Administer amifostine prophylactically before the next cycle

Correct answer: Discontinue cisplatin and notify the oncologist immediately

Tinnitus and high-frequency hearing loss are signs of cisplatin-induced ototoxicity, which requires immediate discontinuation and oncologist notification.

Question 138: A patient receiving FOLFOX chemotherapy develops grade 3 peripheral neuropathy. What is the most appropriate management?

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

Correct answer: Discontinue oxaliplatin permanently

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

Question 139: A cancer patient develops grade 3 peripheral neuropathy (severe symptoms limiting self-care). What is the most appropriate nursing action?

Document findings and notify the oncologist for possible dose reduction or discontinuation (Correct answer)
Continue current chemotherapy and reassess in 2 weeks
Apply heating pads to affected extremities
Recommend over-the-counter vitamin B6 supplements only

Correct answer: Document findings and notify the oncologist for possible dose reduction or discontinuation

Grade 3 peripheral neuropathy is severe and limits daily activities, warranting immediate provider notification for dose modification or treatment discontinuation.

Question 140: A patient with stage IV pancreatic cancer asks about transitioning to hospice care. The oncology NP explains that hospice eligibility typically requires a prognosis of:

Less than 6 months if the disease follows its expected course (Correct answer)
Less than 12 months regardless of treatment status
Less than 3 months if the disease follows its expected course
Inability to perform any activities of daily living

Correct answer: Less than 6 months if the disease follows its expected course

In the US, Medicare hospice benefit eligibility requires a physician-certified prognosis of 6 months or less if the disease runs its expected course.

Question 141: Tumor mutational burden (TMB) is used as a biomarker for which type of immunotherapy response prediction?

Response to PARP inhibitors
Response to anti-VEGF therapy
Response to HER2-targeted therapy
Response to checkpoint inhibitors (Correct answer)

Correct answer: Response to checkpoint inhibitors

High TMB (TMB-H, ≥10 mutations/megabase) is associated with greater neoantigen burden, making tumors more visible to the immune system. Pembrolizumab received FDA approval for TMB-H solid tumors regardless of histology, establishing TMB as a predictive biomarker for checkpoint inhibitor response.

Question 142: Which of the following best describes the concept of 'total pain' as used in palliative care?

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

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 143: The National Comprehensive Cancer Network (NCCN) recommends using which validated tool as the primary distress screening instrument in oncology settings?

NCCN Distress Thermometer (Correct answer)
GAD-7 (Generalized Anxiety Disorder Scale)
PHQ-9 (Patient Health Questionnaire-9)
HADS (Hospital Anxiety and Depression Scale)

Correct answer: NCCN Distress Thermometer

The NCCN Distress Thermometer is the NCCN's recommended brief screening tool, consisting of a 0–10 numerical scale and a problem checklist that identifies practical, family, emotional, spiritual, and physical concerns. A score of 4 or higher warrants further evaluation and referral. While PHQ-9, HADS, and GAD-7 are valid tools, the Distress Thermometer is specifically recommended by NCCN guidelines as the primary oncology distress screen.

Question 144: A patient with locally advanced rectal cancer is scheduled for abdominoperineal resection (APR). Which preoperative bowel preparation practice is currently supported by enhanced recovery after surgery (ERAS) protocols?

Neither mechanical prep nor oral antibiotics are recommended
Mandatory mechanical bowel preparation plus oral antibiotics (Correct answer)
Mechanical bowel preparation alone without oral antibiotics
Oral antibiotics alone without mechanical bowel preparation

Correct answer: Mandatory mechanical bowel preparation plus oral antibiotics

Current ERAS evidence for colorectal surgery supports combined mechanical bowel preparation with oral antibiotics to reduce surgical site infection rates.

Question 145: 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
Hypercalcemia of malignancy
Superior vena cava syndrome
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 146: Which intervention is most effective for managing malignant bowel obstruction in a patient with poor prognosis who is not a surgical candidate?

Octreotide plus corticosteroids plus antiemetics (Correct answer)
Total parenteral nutrition as primary therapy
High-dose laxatives
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 147: Which cervical cancer screening strategy is preferred for a 35-year-old woman per current ASCCP/ACS guidelines?

HPV primary testing alone every 5 years (Correct answer)
Annual Pap smear until age 65
Co-testing (Pap + HPV) every 5 years
Pap smear alone every 3 years

Correct answer: HPV primary testing alone every 5 years

Current ACS guidelines prefer HPV primary testing every 5 years for ages 25-65; co-testing every 5 years is an acceptable alternative when primary HPV testing is unavailable.

Question 148: A patient is newly diagnosed with diffuse large B-cell lymphoma (DLBCL). Which staging system is most appropriate for this hematologic malignancy?

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

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 149: 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
Rasburicase (Correct answer)
Colchicine
Probenecid

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 150: Opioid rotation is indicated when a patient experiences:

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
Solely when insurance requires a generic

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 151: Which risk factor is NOT a criterion for high-risk lung cancer screening with annual LDCT?

Current or former smoker who quit within 15 years
Non-smoker with asbestos exposure (Correct answer)
20 pack-year smoking history
Age 50–80 years

Correct answer: Non-smoker with asbestos exposure

Current USPSTF criteria for lung cancer screening with LDCT require age 50–80 and a 20 pack-year smoking history with current smoking or cessation within 15 years. Asbestos exposure alone does not qualify under the standard USPSTF criteria, though some guidelines recommend individualized consideration.

Question 152: A 52-year-old woman has a BRCA2 pathogenic variant. Regarding ovarian cancer screening, what is the evidence-based recommendation?

Annual pelvic MRI is the preferred modality
Screening is not recommended; risk-reducing salpingo-oophorectomy is preferred (Correct answer)
Transvaginal ultrasound every 6 months starting at age 50
Annual CA-125 plus transvaginal ultrasound is recommended

Correct answer: Screening is not recommended; risk-reducing salpingo-oophorectomy is preferred

Evidence shows CA-125 and transvaginal ultrasound have not reduced ovarian cancer mortality in BRCA carriers; risk-reducing salpingo-oophorectomy at appropriate age is the preferred strategy.

Question 153: Which VEGF pathway inhibitor is associated with a unique toxicity profile including hand-foot skin reaction, hypertension, and hepatotoxicity, and requires liver function monitoring?

Bevacizumab
Sorafenib (Correct answer)
Ramucirumab
Ziv-aflibercept

Correct answer: Sorafenib

Sorafenib, a multi-kinase inhibitor targeting VEGFR and RAF, is specifically associated with hand-foot skin reaction, hypertension, and hepatotoxicity requiring LFT monitoring.

Question 154: 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?

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

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 155: 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?

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

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 156: A patient receiving high-dose methotrexate develops delayed clearance with rising creatinine. Which intervention is most critical?

Reduce methotrexate dose for the next cycle
Give folic acid supplementation and observe
Immediately start dialysis to remove methotrexate
Administer leucovorin rescue and aggressive IV hydration with urinary alkalinization (Correct answer)

Correct answer: Administer leucovorin rescue and aggressive IV hydration with urinary alkalinization

Leucovorin rescue combined with aggressive IV hydration and urinary alkalinization is essential to prevent life-threatening toxicity from delayed methotrexate clearance.

Question 157: A patient with AML develops bleeding gums, petechiae, prolonged PT/PTT, low fibrinogen, and elevated D-dimer. Which treatment is specific to this etiology?

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

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 158: A patient who received thoracic radiation develops new onset cough, low-grade fever, and dyspnea 4–6 weeks after completing treatment. Which diagnosis should be suspected first?

Pulmonary embolism
Bacterial pneumonia requiring broad-spectrum antibiotics
Pleural effusion from disease progression
Radiation pneumonitis (Correct answer)

Correct answer: Radiation pneumonitis

Radiation pneumonitis typically develops 4–12 weeks after thoracic radiation, presenting with low-grade fever, dry cough, and dyspnea. CT shows ground-glass opacities or consolidation within the radiation field. Treatment is high-dose corticosteroids; differentiation from infection is critical.

Question 159: 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 160: In febrile neutropenia, an absolute neutrophil count (ANC) below which threshold defines high-risk neutropenia?

< 1000 cells/mm³
< 500 cells/mm³ (Correct answer)
< 1500 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 161: Which laboratory finding is NOT part of the classic tumor lysis syndrome (TLS) triad?

Hypocalcemia
Hyperkalemia
Hypernatremia (Correct answer)
Hyperphosphatemia

Correct answer: Hypernatremia

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

Question 162: During external beam radiation for prostate cancer, which intervention helps ensure reproducibility and reduces rectal dose?

High-fiber diet throughout treatment course
Filling the bladder and emptying the rectum (rectal preparation) before each fraction (Correct answer)
Lateral patient positioning for all fractions
Voiding the bladder completely before each treatment

Correct answer: Filling the bladder and emptying the rectum (rectal preparation) before each fraction

For prostate EBRT, patients are instructed to have a comfortably full bladder (to push bowel away) and an empty rectum before each treatment session. This setup reproducibility reduces rectal dose, prostate displacement, and acute/late rectal toxicity including proctitis.

Question 163: An oncology NP reviews a study reporting a hazard ratio (HR) of 0.72 with 95% CI 0.58–0.89 for overall survival. How should this be interpreted?

The treatment has no effect because HR is less than 1
The CI crossing 1.0 means the result is not significant
The treatment reduces the risk of death by 28% and the result is statistically significant (Correct answer)
The treatment increases the risk of death by 28%

Correct answer: The treatment reduces the risk of death by 28% and the result is statistically significant

HR < 1 favors the treatment arm, and a 95% CI that does not cross 1.0 indicates statistical significance.

Question 164: According to the TNM staging system, which descriptor indicates that cancer cells have spread to regional lymph nodes?

T2
N1 (Correct answer)
G2
M1

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 165: An operation called a pneumonectomy is occasionally required to treat non-small-cell lung cancer. When performing a pneumonectomy, removal of:

One lobe of a lung
An entire lung field (Correct answer)
One or more segments of a lung lobe
A small, wedge-shaped lung surface

Correct answer: An entire lung field

An full lung field is removed during a pneumonectomy, which is used to treat non-small cell lung cancer that has not spread outside of the lung tissue. Patients who will have sufficient lung function in the unaffected lung are candidates for the procedure.

Question 166: 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 IIA (T2 N1 M0)
Stage IIB (T2 N1 M0) (Correct answer)
Stage IV (T2 N1 M1)
Stage IIIA (T2 N2 M0)

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).
