AOCNP Oncology Nurse Practitioner Certification Exam — Questions and Answers

Question 1: A patient receiving whole-brain radiation therapy (WBRT) is at highest risk for which late cognitive effect?

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

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

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

Question 2: A randomized controlled trial (RCT) in oncology is considered the gold standard for evidence because:

RCTs always include placebo control arms
It is faster and less expensive than observational studies
All patients receive the experimental treatment
Randomization controls for confounding variables and reduces selection bias, allowing causal inference (Correct answer)

Correct answer: Randomization controls for confounding variables and reduces selection bias, allowing causal inference

The RCT is the gold standard because random allocation to treatment and control groups balances known and unknown confounders, minimizing selection bias. This allows valid causal inference about treatment effects. Blinding further controls for performance and detection bias.

Question 3: Which hereditary syndrome requires prophylactic total colectomy due to near-100% lifetime colorectal cancer risk if untreated?

Peutz-Jeghers syndrome
Familial adenomatous polyposis (FAP) (Correct answer)
MUTYH-associated polyposis
Lynch syndrome

Correct answer: Familial adenomatous polyposis (FAP)

FAP patients develop hundreds to thousands of colonic polyps beginning in adolescence, with virtually 100% progression to colorectal cancer if colectomy is not performed.

Question 4: Bispecific T-cell engager (BiTE) blinatumomab works by simultaneously binding which two targets?

HER2 and EGFR
VEGFR and PDGFR
CD3 on T cells and CD19 on B-cell tumors (Correct answer)
PD-1 and CTLA-4

Correct answer: CD3 on T cells and CD19 on B-cell tumors

Blinatumomab is a bispecific antibody that bridges CD3 (on cytotoxic T cells) and CD19 (on B-cell malignancies), directing T cells to kill leukemic B cells. It is approved for relapsed/refractory ALL and minimal residual disease (MRD)-positive B-cell ALL.

Question 5: Which laboratory finding is most consistent with tumor lysis syndrome?

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

Correct answer: Hyperkalemia, hyperphosphatemia, hypocalcemia, hyperuricemia

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

Question 6: A patient with lung cancer develops facial plethora, arm edema, and distended neck veins. Which imaging study is the priority?

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

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 7: 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?

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

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 8: 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?

Beneficence
Non-maleficence
Autonomy (Correct answer)
Justice

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

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

Correct answer: Ciprofloxacin plus amoxicillin-clavulanate

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

Question 10: Which risk factor is NOT a criterion for high-risk lung cancer screening with annual LDCT?

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

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

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

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 12: A patient receiving cisplatin-based chemotherapy develops severe nausea and vomiting despite standard antiemetics. Which agent targets substance P/NK-1 receptors and is most appropriate to add?

Ondansetron
Metoclopramide
Lorazepam
Aprepitant (Correct answer)

Correct answer: Aprepitant

Aprepitant is a neurokinin-1 (NK-1) receptor antagonist that blocks substance P binding, effective for delayed emesis associated with highly emetogenic chemotherapy.

Question 13: Which taxane is approved for albumin-bound nanoparticle formulation to reduce hypersensitivity and improve delivery?

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

Correct answer: Nab-paclitaxel (Abraxane)

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

Question 14: A hospice patient develops myoclonic jerks and hyperalgesia after high-dose morphine. Which action best addresses opioid-induced neurotoxicity?

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

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

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

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 16: Cancer-related cognitive impairment (CRCI or 'chemo brain') is characterized by which cluster of symptoms?

Frank dementia with loss of long-term memory
Severe aphasia and motor dysfunction
Subtle deficits in memory, attention, processing speed, and executive function (Correct answer)
Psychosis and personality changes

Correct answer: Subtle deficits in memory, attention, processing speed, and executive function

CRCI (chemotherapy-related cognitive changes/chemo brain) presents as subjective and objective deficits primarily in attention, working memory, processing speed, and executive function. It is distinct from dementia and may be subtle but significantly impacts quality of life and occupational function. Assessment tools include FACT-Cog.

Question 17: In a Phase I clinical trial for a new oncology drug, the primary objective is to determine:

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

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 18: Radiation-induced lymphedema after axillary irradiation for breast cancer is best prevented by:

Complete arm immobilization for 6 months
Tight compression bandaging from day one of radiation
Avoiding trauma, infection, venipuncture, and blood pressure measurement in the affected arm, combined with weight management (Correct answer)
Prophylactic antibiotic use throughout treatment

Correct answer: Avoiding trauma, infection, venipuncture, and blood pressure measurement in the affected arm, combined with weight management

Protecting the at-risk limb from infection, trauma, and compressive procedures minimizes additional lymphatic damage in an already compromised system.

Question 19: When managing a patient with radiation recall dermatitis triggered by docetaxel administered after prior radiation, the MOST appropriate initial intervention is:

Performing a skin biopsy to confirm diagnosis before any treatment change
Immediate re-irradiation of the affected area at a lower dose
Withholding the offending chemotherapy agent and treating with topical corticosteroids (Correct answer)
Applying silver sulfadiazine cream and continuing chemotherapy at reduced dose

Correct answer: Withholding the offending chemotherapy agent and treating with topical corticosteroids

Radiation recall dermatitis is managed by discontinuing the triggering agent and using topical or systemic corticosteroids; re-challenge decisions are made after resolution based on clinical necessity.

Question 20: Radiation recall is defined as:

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

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 21: A patient with Waldenström macroglobulinemia presents with episodic Raynaud phenomenon, urticaria, and hyperviscosity. Which immunoglobulin class is responsible?

IgM (Correct answer)
IgA
IgE
IgG

Correct answer: IgM

Waldenström macroglobulinemia is characterized by a monoclonal IgM paraprotein; its large pentameric structure causes hyperviscosity and cold agglutinin/cryoglobulin phenomena.

Question 22: An AOCNP is managing a patient on tamoxifen who is also prescribed paroxetine for depression. What is the primary concern?

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

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

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

Question 23: The 32-year-old patient sees the nurse for the first time following having a left mastectomy. When asked how she is doing, the woman replies that her appetite is still not great, she is not sleeping well since she waits to go to bed until her husband is asleep, and she is quite eager to start working again. Which nursing interventions from the list below should the nurse look into to address the client's present needs?

Ask open-ended questions about sexuality issues related to her mastectomy (Correct answer)
Call the physician to discuss allowing the client to return to work earlier
Suggest that the client learn relaxation techniques to help with her insomnia
Perform a nutritional assessment to assess for anorexia

Correct answer: Ask open-ended questions about sexuality issues related to her mastectomy

The client's comments seem to indicate that by waiting until her spouse is sleeping before going to bed, she is avoiding intimacy with him. It is appropriate for a client who has had a mastectomy to talk about sexuality difficulties.

Question 24: Venous thromboembolism (VTE) prophylaxis in cancer surgery patients typically involves which combination?

Warfarin anticoagulation starting immediately after surgery
Pharmacologic prophylaxis (LMWH) plus mechanical prophylaxis (sequential compression devices) (Correct answer)
No prophylaxis — VTE risk is the same as general surgical patients
Antiplatelet therapy (aspirin) alone

Correct answer: Pharmacologic prophylaxis (LMWH) plus mechanical prophylaxis (sequential compression devices)

Cancer patients have 2–6× higher VTE risk than non-cancer surgical patients due to hypercoagulability. Combined mechanical (SCDs) and pharmacologic (LMWH/heparin) prophylaxis beginning perioperatively, with extended prophylaxis for 28 days post-discharge for high-risk abdominal/pelvic cancer surgery, is standard of care.

Question 25: A patient develops sudden-onset dyspnea, muffled heart sounds, hypotension, and jugular venous distension. Which emergency is this?

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

Correct answer: Cardiac tamponade

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

Question 26: A patient receiving cisplatin-based chemotherapy develops tinnitus and decreased high-frequency hearing. Which intervention is most appropriate?

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
Reduce the cisplatin dose by 25% and continue

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

Febrile neutropenia (Correct answer)
Hypercalcemia of malignancy
Spinal cord compression
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 28: In myelodysplastic syndrome (MDS), which cytogenetic finding is associated with the best prognosis and typically responds to lenalidomide?

Del(17p)
Monosomy 7
Complex karyotype (≥3 abnormalities)
Del(5q) (Correct answer)

Correct answer: Del(5q)

Isolated del(5q) MDS has an excellent prognosis and is uniquely sensitive to lenalidomide, which targets the haploinsufficient CSNK1A1 gene on 5q.

Question 29: Helicobacter pylori eradication is a primary prevention strategy for which cancer?

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

Correct answer: Gastric adenocarcinoma and gastric MALT lymphoma

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

Question 30: The survivorship care plan should include which minimum components per ASCO/IOM recommendations?

Insurance and billing information with treatment codes
Treatment summary, surveillance schedule, late effect information, and referrals for ongoing care needs (Correct answer)
Diagnosis date and pathology report only
Only a list of current medications and allergies

Correct answer: Treatment summary, surveillance schedule, late effect information, and referrals for ongoing care needs

Per ASCO and IOM standards, the survivorship care plan must include: (1) treatment summary (diagnosis, staging, treatments received with dates/doses), (2) surveillance/monitoring schedule for recurrence, (3) potential late and long-term effects with management guidance, and (4) referrals and resources (primary care, mental health, rehabilitation, community support).

Question 31: A patient with malignant bowel obstruction is not a surgical candidate. Which combination is most appropriate for symptom management?

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

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

Stage II non-small cell lung cancer
Multiple myeloma (Correct answer)
Stage I endometrial cancer
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 33: Lynch syndrome increases lifetime risk of which cancer most significantly?

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

Correct answer: Colorectal cancer

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

Question 34: The principle of equipoise in clinical trial ethics means:

There is genuine uncertainty about which treatment arm is superior, justifying randomization (Correct answer)
All participants must receive the same treatment
Participants must be equally distributed across age groups
The trial must include equal numbers of males and females

Correct answer: There is genuine uncertainty about which treatment arm is superior, justifying randomization

Clinical equipoise means there is genuine scientific uncertainty in the expert medical community about which treatment is superior. Equipoise is the ethical justification for randomizing patients — if one treatment is clearly superior, randomization would be unethical. When evidence tips decisively in one direction, trials are stopped by data safety monitoring boards.

Question 35: A patient with small cell lung cancer presents with hyponatremia (Na 118 mEq/L), concentrated urine, and euvolemia. Which oncologic emergency is most likely?

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

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 36: The Rai and Binet staging systems are used to classify the prognosis of which hematologic malignancy?

Hodgkin lymphoma
Multiple myeloma
Chronic myeloid leukemia (CML)
Chronic lymphocytic leukemia (CLL) (Correct answer)

Correct answer: Chronic lymphocytic leukemia (CLL)

The Rai (US) and Binet (European) staging systems stratify CLL patients into risk groups based on lymphocytosis, lymphadenopathy, organomegaly, and cytopenias.

Question 37: 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?

Protect normal kidney cells from the damaging effects of chemotherapy
Enhance the patient's immunologic response to tumor cells (Correct answer)
Stimulate malignant cells in the resting phase to enter mitosis
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 38: A patient with AML develops bleeding gums, petechiae, prolonged PT/PTT, low fibrinogen, and elevated D-dimer. Which treatment is specific to this etiology?

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

Correct answer: All-trans retinoic acid (ATRA)

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

Question 39: Which grading tool is most appropriate for evaluating chemotherapy-induced peripheral neuropathy (CIPN) severity in clinical oncology practice?

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

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

Dermatologic toxicity and QTc prolongation (Correct answer)
Grade 3–4 mucositis
Severe cytokine release syndrome
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 41: The BRCA1/2 mutation confers the highest lifetime risk for which two cancers?

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

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 42: The mechanism of action of methotrexate is:

Inhibition of dihydrofolate reductase, depleting folate required for DNA synthesis (Correct answer)
Binding to tubulin to prevent spindle formation
Intercalation between DNA base pairs
Inhibition of topoisomerase II

Correct answer: Inhibition of dihydrofolate reductase, depleting folate required for DNA synthesis

Methotrexate inhibits DHFR, preventing reduction of folate to its active form and thereby blocking thymidylate and purine synthesis.

Question 43: 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 active pneumonia and hypotension (Correct answer)
Patient reports mild nausea but is able to swallow pills
Patient has controlled diabetes and lives 20 minutes from the hospital

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 44: A 58-year-old male was diagnosed with Hodgkin's disease and is being admitted for the first round of chemotherapy. The nurse should be on the lookout for the following complications while the patient is in the hospital, but?

Secondary cancer
Fertility problems
Benign prostatic hyperplasia (Correct answer)
Infection

Correct answer: Benign prostatic hyperplasia

With symptoms like painless swelling of a lymph node, recurrent fever, night sweats, pruritus, and unexplained weight loss, Hodgkin's disease (also known as Hodgkin's lymphoma) is a type of cancer that affects the lymphatic system (including the bone marrow, spleen, liver, and lymph node tissue).

Question 45: Radiation recall is an acute dermatitis reaction triggered by certain chemotherapy agents administered after prior radiation. Which agent is most classically associated with radiation recall?

Vincristine
Carboplatin
Doxorubicin (Adriamycin) (Correct answer)
Cyclophosphamide

Correct answer: Doxorubicin (Adriamycin)

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

Question 46: Which laboratory finding is NOT part of the classic tumor lysis syndrome (TLS) triad?

Hyperphosphatemia
Hypocalcemia
Hyperkalemia
Hypernatremia (Correct answer)

Correct answer: Hypernatremia

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

Question 47: What is the primary mechanism by which ionizing radiation kills cancer cells?

Directly disrupting cell membrane integrity
Inducing DNA double-strand breaks leading to apoptosis or mitotic catastrophe (Correct answer)
Activating natural killer cells to attack tumor cells
Inhibiting angiogenesis within the tumor microenvironment

Correct answer: Inducing DNA double-strand breaks leading to apoptosis or mitotic catastrophe

Radiation kills cells primarily through direct and indirect (free radical-mediated) DNA double-strand breaks. Cells unable to repair this damage undergo apoptosis, necrosis, or mitotic catastrophe. Rapidly dividing cells are most sensitive due to less time for DNA repair between divisions.

Question 48: 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 49: The Edmonton Symptom Assessment System (ESAS) measures which of the following?

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

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

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

Correct answer: Septic shock

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

Question 51: What is the recommended screening interval for average-risk colonoscopy in patients with no polyps found?

Every 15 years
Every 10 years (Correct answer)
Every 3 years
Every 5 years

Correct answer: Every 10 years

For average-risk patients with a negative colonoscopy (no adenomas or polyps), the recommended rescreening interval is 10 years, as colorectal cancer development from normal mucosa typically requires 10 or more years.

Question 52: Rasburicase is contraindicated in which patient population due to risk of hemolytic anemia?

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

Correct answer: Patients with G6PD deficiency

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

Question 53: A patient undergoing pelvic radiation for cervical cancer reports diarrhea, cramping, and rectal bleeding 6 weeks after completing treatment. What is the most likely diagnosis?

Clostridium difficile colitis
Chronic radiation enteritis (Correct answer)
Radiation-induced colorectal cancer
Acute radiation proctitis

Correct answer: Chronic radiation enteritis

Symptoms appearing weeks to months after completing pelvic radiation are consistent with chronic radiation enteritis, which can develop from 6 weeks to years post-treatment.

Question 54: 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 closely resembles normal tissue and likely grows slowly
The tumor shows moderate resemblance to normal tissue
The tumor bears little resemblance to normal tissue and is likely more aggressive (Correct answer)

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 55: Which of the following tumor markers is most useful in the early detection and monitoring of ovarian cancer?

AFP
CA-125 (Correct answer)
CEA
PSA

Correct answer: CA-125

CA-125 is the primary serum biomarker used in ovarian cancer detection and monitoring. While not recommended for population screening due to low specificity, it is valuable in high-risk patients and for monitoring response to treatment.

Question 56: Sentinel lymph node biopsy (SLNB) is performed to assess regional lymph node status while avoiding which complication of full axillary lymph node dissection?

Wound infection
Seroma formation exclusively
Hematoma formation
Lymphedema (Correct answer)

Correct answer: Lymphedema

SLNB was developed to accurately stage regional lymph nodes while minimizing the morbidity of complete axillary lymph node dissection (ALND), particularly lymphedema. The sentinel node (first draining node) is identified using blue dye and/or radioactive tracer; if negative, ALND is avoided.

Question 57: A pathologic complete response (pCR) after neoadjuvant chemotherapy for breast cancer is most significant because it is associated with:

No further need for adjuvant therapy
Automatic classification as stage I disease
Eligibility for less extensive surgery only
Improved disease-free and overall survival (Correct answer)

Correct answer: Improved disease-free and overall survival

Pathologic complete response (no residual invasive cancer in the breast or lymph nodes at surgery) following neoadjuvant chemotherapy is a strong prognostic marker associated with significantly improved disease-free and overall survival, particularly in HER2-positive and triple-negative breast cancer.

Question 58: 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)
Topical estrogen cream daily throughout treatment
Pelvic floor physical therapy starting on day 1 of radiation
Avoid all pelvic examinations until 1 year post-treatment

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

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

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

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

Correct answer: Thrombocytopenia and increased lymphocytes

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

Question 61: Which scale is most widely validated for assessing pain intensity in cognitively intact cancer patients?

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

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 62: The Bethesda System is used to classify results from which cancer screening test?

Colonoscopy
PSA testing
Pap smear (cervical cytology) (Correct answer)
Mammography

Correct answer: Pap smear (cervical cytology)

The Bethesda System provides standardized terminology for reporting cervical cytology (Pap smear) results, categorizing findings from normal to high-grade squamous intraepithelial lesions (HSIL), which guides clinical management.

Question 63: When reviewing a solid tumor's comprehensive genomic profiling (CGP) report, which finding would most directly guide selection of a PARP inhibitor as targeted therapy?

High tumor mutational burden (TMB-H ≥ 10 mut/Mb)
PD-L1 expression ≥ 50%
Homologous recombination deficiency (HRD) or BRCA1/2 somatic mutation (Correct answer)
Microsatellite instability-high (MSI-H) status

Correct answer: Homologous recombination deficiency (HRD) or BRCA1/2 somatic mutation

PARP inhibitors exploit synthetic lethality in tumors with defective homologous recombination repair, most commonly caused by BRCA1/2 mutations or HRD. TMB-H and MSI-H guide immunotherapy selection (pembrolizumab). High PD-L1 also guides checkpoint inhibitor use. HRD/BRCA mutation status is the biomarker predictive of PARP inhibitor response.

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

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

Correct answer: Serum creatinine and urine pH

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

Question 65: Cytokine release syndrome (CRS) is a potentially life-threatening toxicity most commonly associated with which type of immunotherapy?

PARP inhibitors
PD-1 checkpoint inhibitors
CAR-T cell therapy and bispecific T-cell engagers (Correct answer)
Anti-VEGF monoclonal antibodies

Correct answer: CAR-T cell therapy and bispecific T-cell engagers

CRS occurs when large numbers of immune cells are activated and release excessive cytokines (especially IL-6, IFN-γ), causing fever, hypotension, and hypoxia. It is most severe with CAR-T therapies (e.g., tisagenlecleucel) and bispecific T-cell engagers (e.g., blinatumomab). Tocilizumab is the treatment of choice for severe CRS.

Question 66: Checkpoint inhibitors targeting PD-1 (e.g., pembrolizumab) cause a distinctive class of toxicities called:

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

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

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

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

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

Question 68: Which biologic agent works by depleting CD20-positive B cells and is used in certain lymphomas?

Rituximab (Correct answer)
Ramucirumab
Denosumab
Cetuximab

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

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

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 70: Which of the following best describes the concept of 'dose painting' in radiation therapy?

Delivering higher radiation doses to metabolically active or hypoxic tumor subvolumes (Correct answer)
Painting the treatment field on the patient's skin for daily setup verification
Applying topical agents to irradiated skin to reduce dermatitis
Using multiple beam angles to achieve a uniform dose across the target

Correct answer: Delivering higher radiation doses to metabolically active or hypoxic tumor subvolumes

Dose painting uses functional imaging (e.g., PET, MRI) to identify tumor subvolumes requiring higher doses, such as hypoxic or FDG-avid regions, and boosts dose selectively to those areas.

Question 71: 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 72: Prophylactic cranial irradiation (PCI) is standard of care for which cancer type to reduce the risk of brain metastases?

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

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

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

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

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

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

Allopurinol (Correct answer)
Hydroxyurea
Sodium bicarbonate
Rasburicase

Correct answer: Allopurinol

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

Question 76: Which non-pharmacological intervention has the strongest evidence for reducing cancer-related fatigue?

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

Correct answer: Aerobic exercise

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

Question 77: Tobacco cessation counseling is a primary prevention intervention most critically indicated for which cancer risk reduction?

Cervical cancer specifically
Colorectal and prostate cancers only
Breast cancer only
Lung, head and neck, bladder, esophageal, and pancreatic cancers (Correct answer)

Correct answer: Lung, head and neck, bladder, esophageal, and pancreatic cancers

Tobacco is carcinogenic across multiple organ systems — smoking causes 30% of all cancer deaths and cessation reduces risk for at least 12 different cancer types.

Question 78: Late radiation toxicity in the pelvis most commonly manifests as which of the following?

Radiation proctitis, cystitis, or small bowel injury (Correct answer)
Acute radiation dermatitis
Acute nausea and vomiting
Immediate hair loss in the field

Correct answer: Radiation proctitis, cystitis, or small bowel injury

Late pelvic radiation effects (occurring >3–6 months post-treatment) include radiation proctitis (rectal bleeding, tenesmus), hemorrhagic cystitis, small bowel obstruction, fistula formation, and sexual dysfunction. These differ from acute effects and may be permanent or progressive.

Question 79: 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
Add a second opioid at the same dose
Increase by 25–33% (Correct answer)
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 80: Radiation-induced fatigue is best managed with which evidence-based intervention during active treatment?

High-dose corticosteroids throughout treatment
Complete bed rest throughout radiation course
Moderate aerobic exercise (walking program) (Correct answer)
Stimulant medications such as methylphenidate daily

Correct answer: Moderate aerobic exercise (walking program)

Evidence consistently supports moderate aerobic exercise (150 min/week of moderate intensity) as the most effective intervention for cancer-related fatigue during and after radiation. Exercise improves energy levels, mood, and quality of life without adversely affecting treatment outcomes.

Question 81: Which skin care instruction is correct for patients undergoing external beam radiation therapy to the breast?

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

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 82: 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 83: Which validated screening tool is most widely recommended for identifying nutritional risk in hospitalized oncology patients?

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

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

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

Question 84: Which of the following conditions best describes stage III of the Hodgkin's disease staging system?

Involvement of two or more lymph node regions or structures
Involvement of single lymph node region or structure
Involvement of extralymphatic organs or tissues
Involvement of lymph node regions or structures on both sides of the diaphragm (Correct answer)

Correct answer: Involvement of lymph node regions or structures on both sides of the diaphragm

To assess the severity of the condition and the extent of the disease's spread, Hodgkin lymphoma is divided into phases. Nodes on both sides of the diaphragm are involved in stage III.

Question 85: Which surface marker combination is most characteristic of hairy cell leukemia (HCL)?

CD34+, CD117+, CD13+
CD5+, CD23+, CD19+
CD19+, CD20+, CD11c+, CD25+, CD103+ (Correct answer)
CD3+, CD4+, CD30+

Correct answer: CD19+, CD20+, CD11c+, CD25+, CD103+

HCL classically expresses CD19, CD20, CD11c, CD25, CD103, and annexin A1, distinguishing it from other B-cell lymphoproliferative disorders.

Question 86: Which of the following is the FIRST-LINE treatment for malignant spinal cord compression (MSCC) once the diagnosis is confirmed?

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

Correct answer: High-dose corticosteroids (dexamethasone)

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

Question 87: Which cancer type is most commonly associated with disseminated intravascular coagulation (DIC) in adults?

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

Correct answer: Acute promyelocytic leukemia (APL)

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

Question 88: In brachytherapy for cervical cancer, the point 'Point A' is used to prescribe dose. Where is Point A located?

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

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

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

Question 89: Which biomarker must be tested before initiating trastuzumab (Herceptin) therapy for breast cancer?

EGFR mutation
PD-L1 expression level
KRAS mutation status
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 90: Which of the following best describes the mechanism of action of bortezomib in multiple myeloma?

Inhibits the 26S proteasome, preventing degradation of pro-apoptotic factors (Correct answer)
Blocks PD-1/PD-L1 interaction to restore T-cell function
Inhibits BCR-ABL tyrosine kinase
Alkylates DNA leading to cross-linking and strand breaks

Correct answer: Inhibits the 26S proteasome, preventing degradation of pro-apoptotic factors

Bortezomib is a proteasome inhibitor that prevents degradation of regulatory proteins, promoting apoptosis in myeloma cells.

Question 91: In the revised International Prognostic Index (R-IPI) for DLBCL, which of the following is NOT one of the five adverse prognostic factors?

Elevated LDH
ECOG performance status >1
Age >60 years
Bone marrow involvement (Correct answer)

Correct answer: Bone marrow involvement

The R-IPI uses age >60, elevated LDH, ECOG PS >1, Ann Arbor stage III/IV, and >1 extranodal site; bone marrow involvement per se is not a standalone factor.

Question 92: Which class of immunotherapy works by blocking the PD-1/PD-L1 checkpoint pathway to restore anti-tumor T-cell activity?

CAR-T cell therapy
Cytotoxic T-lymphocyte vaccines
Checkpoint inhibitors (Correct answer)
Monoclonal antibodies targeting HER2

Correct answer: Checkpoint inhibitors

Checkpoint inhibitors such as pembrolizumab (anti-PD-1), nivolumab (anti-PD-1), and atezolizumab (anti-PD-L1) block inhibitory signals that tumor cells use to suppress T-cell activity, thereby restoring the immune system's ability to recognize and destroy cancer cells.

Question 93: Concurrent chemoradiation is superior to radiation alone in which cancers because chemotherapy acts as a:

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

Correct answer: Radiosensitizer that enhances tumor cell kill by radiation

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

Question 94: Cardiotoxicity is the major dose-limiting toxicity associated with which chemotherapy class?

Anthracyclines (Correct answer)
Taxanes
Platinum compounds
Alkylating agents

Correct answer: Anthracyclines

Anthracyclines (doxorubicin, epirubicin) cause cumulative, dose-dependent cardiomyopathy through free-radical-mediated myocyte damage.

Question 95: Which lifestyle modification has the strongest evidence for reducing cancer risk overall?

Elimination of all red meat
Avoidance of all alcohol
Daily vitamin D supplementation
Tobacco cessation (Correct answer)

Correct answer: Tobacco cessation

Tobacco cessation is the single most impactful lifestyle modification, responsible for preventing approximately 30% of all cancer deaths across multiple cancer types.

Question 96: Tumor mutational burden (TMB) is used as a biomarker for which type of immunotherapy response prediction?

Response to PARP inhibitors
Response to HER2-targeted therapy
Response to anti-VEGF 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 97: Opioid rotation is indicated when a patient experiences:

Only when switching from oral to IV route
Inadequate analgesia or intolerable side effects despite dose optimization (Correct answer)
Any mild side effect within 24 hours
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 98: An oncology nurse is assessing a patient for superior vena cava (SVC) syndrome. Which early sign should prompt immediate action?

Fever and chills
Facial edema and arm swelling worse in the morning (Correct answer)
Hypotension and tachycardia
Dependent edema in bilateral lower extremities

Correct answer: Facial edema and arm swelling worse in the morning

Facial and arm edema that is worse upon awakening is an early hallmark of SVC syndrome due to venous obstruction.

Question 99: Which omega-3 fatty acid supplement has the most evidence supporting its use in cancer patients for attenuating weight loss and improving outcomes during chemotherapy?

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

Correct answer: EPA (eicosapentaenoic acid) from fish oil

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

Question 100: Post-treatment sexual dysfunction in female cancer survivors most commonly manifests as which symptoms?

Increased libido and hypersexuality
Dyspareunia, vaginal dryness, and decreased libido (Correct answer)
Only reproductive infertility without sexual symptom changes
Urinary incontinence exclusively

Correct answer: Dyspareunia, vaginal dryness, and decreased libido

Genitourinary syndrome of menopause (GSM) related to cancer treatment (ovarian failure, aromatase inhibitors, pelvic radiation) causes vaginal atrophy, dryness, dyspareunia, and decreased libido. Non-hormonal treatments (lubricants, moisturizers, vaginal dilators, ospemifene) and low-dose vaginal estrogen (where appropriate) are first-line management.

Question 101: Which prognostic tool is validated to estimate survival in weeks to months for palliative care patients?

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

Correct answer: Palliative Performance Scale (PPS)

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

Question 102: 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)
High-dose laxatives
Total parenteral nutrition as primary therapy
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 103: Which type of systematic review and meta-analysis evidence is considered the highest level in the evidence hierarchy for oncology treatment decisions?

Systematic review/meta-analysis of multiple high-quality RCTs (Level I evidence) (Correct answer)
Single large prospective cohort study
Retrospective database analysis
Expert opinion and case series

Correct answer: Systematic review/meta-analysis of multiple high-quality RCTs (Level I evidence)

In the evidence hierarchy (Level I–V), Level I evidence represents systematic reviews and meta-analyses that pool results from multiple well-designed RCTs using rigorous methodology. This provides the most reliable estimate of treatment effects by maximizing statistical power and controlling for bias across studies.

Question 104: Syndrome of inappropriate antidiuretic hormone secretion (SIADH) in cancer is best managed initially with:

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

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

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

Question 105: Which statement best describes the mechanism of resistance to imatinib in chronic myeloid leukemia (CML)?

Point mutations in the BCR-ABL kinase domain, particularly T315I (Correct answer)
Increased expression of VEGF bypassing BCR-ABL signaling
Upregulation of mismatch repair genes
Overexpression of topoisomerase II preventing drug binding

Correct answer: Point mutations in the BCR-ABL kinase domain, particularly T315I

The T315I gatekeeper mutation in BCR-ABL is the most common and problematic resistance mutation, conferring resistance to first- and second-generation TKIs.

Question 106: Which of the following best describes the concept of 'total pain' as used in palliative care?

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

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

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

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

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

Question 108: Which medication is first-line for neuropathic pain in cancer patients?

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

Correct answer: Gabapentin or pregabalin

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

Question 109: Which unit of measurement quantifies the absorbed radiation dose in modern oncology practice?

Rad
Gray (Gy) (Correct answer)
Curie (Ci)
Roentgen (R)

Correct answer: Gray (Gy)

The Gray (Gy) is the SI unit of absorbed radiation dose, equal to 1 joule of energy absorbed per kilogram of tissue.

Question 110: A colorectal cancer survivor who completed curative resection should receive which surveillance study at 1 year post-surgery?

Annual PET/CT only
CT colonography every 6 months for 5 years
CEA measurement only, no colonoscopy needed
Colonoscopy at 1 year post-resection (if not done preoperatively), then per findings (Correct answer)

Correct answer: Colonoscopy at 1 year post-resection (if not done preoperatively), then per findings

ASCO/NCCN guidelines for colorectal cancer surveillance recommend colonoscopy at 1 year after surgery (or within 3–6 months if preoperative colonoscopy was incomplete). If normal, repeat at 3 years, then every 5 years, along with CEA monitoring every 3–6 months for 5 years and CT chest/abdomen/pelvis annually for 3–5 years.

Question 111: Which regulatory body requires submission of an Investigational New Drug (IND) application before clinical trials of a new agent can begin in the United States?

Centers for Medicare & Medicaid Services (CMS)
Food and Drug Administration (FDA) (Correct answer)
National Cancer Institute (NCI)
Institutional Review Board (IRB)

Correct answer: Food and Drug Administration (FDA)

The FDA requires an IND application before a new drug or biological product can be administered to humans in the U.S. The IND contains preclinical data, manufacturing information, clinical protocols, and investigator qualifications. FDA has 30 days to review; if no clinical hold is placed, the trial may proceed.

Question 112: Which electrolyte abnormality is NOT typically associated with tumor lysis syndrome (TLS)?

Hypernatremia (Correct answer)
Hypocalcemia
Hyperkalemia
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 113: An important factor to keep in mind when the nurse administers a vesicant chemotherapeutic drug intravenously is to:

Administer the chemotherapy through a small-bore catheter
Hold the medication unless a central venous line is available
Infuse the medication over a short period
Stop the infusion if swelling is observed at the site (Correct answer)

Correct answer: Stop the infusion if swelling is observed at the site

Extravasation may cause the area to swell, in which case the IV should be discontinued right away.

Question 114: A patient with newly diagnosed AML has FLT3-ITD mutation. Which targeted agent should be added to induction chemotherapy?

Midostaurin (Correct answer)
Imatinib
Ibrutinib
Venetoclax

Correct answer: Midostaurin

Midostaurin, a FLT3 inhibitor, is added to standard 7+3 induction chemotherapy for FLT3-mutated AML to improve outcomes.

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

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

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

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

Question 116: Which psychosocial phenomenon describes the positive psychological growth and transformation that some cancer survivors experience after their diagnosis and treatment?

Adjustment disorder with anxious mood
Post-traumatic growth (PTG) (Correct answer)
Survivor guilt
Somatization disorder

Correct answer: Post-traumatic growth (PTG)

Post-traumatic growth (PTG) refers to positive psychological change (greater appreciation for life, deeper relationships, increased personal strength, spiritual development, new possibilities) that can emerge through the struggle with highly challenging life circumstances such as cancer diagnosis and treatment.

Question 117: A patient is newly diagnosed with diffuse large B-cell lymphoma (DLBCL). Which staging system is most appropriate for this hematologic malignancy?

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

Correct answer: Lugano classification (modified Ann Arbor staging)

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

Question 118: Which of the following is the most accurate description of a complete cytogenetic response (CCyR) to imatinib therapy in CML?

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

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

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

Question 119: Radiation-induced xerostomia (dry mouth) is most effectively prevented by which technique when treating head and neck cancers?

Amifostine premedication before every fraction
Using brachytherapy for all head and neck cancers
Reducing the total radiation dose below 30 Gy
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 120: 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
Thrombocytopenia from chemotherapy
Tumor lysis syndrome
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 121: Which oncology clinical trial design allows all patients to eventually receive the experimental treatment, eliminating the ethical concern of permanent denial of a potentially beneficial therapy?

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

Correct answer: Crossover trial design

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

Question 122: Imatinib (Gleevec) is a tyrosine kinase inhibitor (TKI) that targets which molecular abnormality in chronic myelogenous leukemia (CML)?

EGFR mutation
ALK rearrangement
HER2 amplification
BCR-ABL fusion protein (Correct answer)

Correct answer: BCR-ABL fusion protein

Imatinib specifically inhibits the BCR-ABL tyrosine kinase produced by the Philadelphia chromosome (t(9;22) translocation) in CML. It was the first targeted therapy to demonstrate that molecular targeting of a cancer driver mutation could produce durable remissions.

Question 123: Which laxative regimen should ALWAYS accompany opioid therapy to prevent constipation?

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

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 124: A patient on pembrolizumab develops a skin rash covering 35% of body surface area with mucosal involvement. What is the FIRST priority action?

Reduce pembrolizumab dose by 50%
Hold pembrolizumab and initiate systemic corticosteroids
Permanently discontinue pembrolizumab and initiate IV corticosteroids (Correct answer)
Apply topical corticosteroids and continue pembrolizumab

Correct answer: Permanently discontinue pembrolizumab and initiate IV corticosteroids

Grade 3 immune-mediated dermatitis with mucosal involvement requires permanent discontinuation of the checkpoint inhibitor and systemic high-dose corticosteroids.

Question 125: Which electrolyte abnormality most immediately threatens cardiac function in tumor lysis syndrome?

Hyperkalemia (Correct answer)
Hypocalcemia
Hyperphosphatemia
Hyperuricemia

Correct answer: Hyperkalemia

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

Question 126: PARP inhibitors such as olaparib are most effective in patients with which molecular feature?

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

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

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

Question 127: An AOCNP is counseling the family of a dying patient about the 'death rattle.' Which statement is most accurate?

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

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

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

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 129: EGFR-mutated non-small cell lung cancer (NSCLC) is most effectively treated with which class of targeted agents?

ALK inhibitors (e.g., crizotinib)
EGFR tyrosine kinase inhibitors (e.g., osimertinib) (Correct answer)
VEGF inhibitors (bevacizumab)
KRAS G12C inhibitors (e.g., sotorasib)

Correct answer: EGFR tyrosine kinase inhibitors (e.g., osimertinib)

EGFR TKIs, particularly third-generation osimertinib, are first-line standard of care for EGFR-mutated (exon 19 deletion or L858R) NSCLC. Osimertinib also covers T790M resistance mutations and has better CNS penetration compared to first/second-generation TKIs.

Question 130: Which term describes a trial design where a new agent is tested across multiple cancer types based on a shared molecular target (biomarker) rather than tumor histology?

Crossover trial
Basket trial (Correct answer)
Umbrella trial
Platform trial

Correct answer: Basket trial

Basket trials (also called histology-agnostic or tumor-agnostic trials) enroll patients across different tumor types that share a specific molecular alteration (e.g., NTRK fusion, MSI-H, BRAF V600E), testing whether a targeted therapy works regardless of tissue of origin. Examples: larotrectinib (NTRK), pembrolizumab (MSI-H).

Question 131: Which first-line intervention is indicated for hypercalcemia of malignancy with corrected serum calcium > 14 mg/dL?

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

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 132: Irinotecan causes severe delayed diarrhea through which mechanism?

Direct mucosal alkylation
Antimetabolite interference with enterocyte folate metabolism
Serotonin release in the gut
Active SN-38 metabolite inhibiting topoisomerase I in intestinal epithelium (Correct answer)

Correct answer: Active SN-38 metabolite inhibiting topoisomerase I in intestinal epithelium

SN-38, the active metabolite of irinotecan, is excreted into the intestinal lumen via bile, where it damages epithelial cells causing delayed secretory diarrhea.

Question 133: 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 IV (T2 N1 M1)
Stage IIA (T2 N1 M0)
Stage IIIA (T2 N2 M0)
Stage IIB (T2 N1 M0) (Correct answer)

Correct answer: Stage IIB (T2 N1 M0)

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

Question 134: A patient receiving high-dose methotrexate develops delayed clearance with rising creatinine. Which intervention is most critical?

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

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 135: PARP inhibitors such as olaparib are most effective in tumors with defects in which repair pathway?

Nucleotide excision repair
Base excision repair only
Homologous recombination (BRCA1/2 mutations) (Correct answer)
Mismatch repair

Correct answer: Homologous recombination (BRCA1/2 mutations)

BRCA1/2-mutated tumors rely solely on PARP-mediated base excision repair; olaparib blocks PARP, causing lethal synthetic lethality in HR-deficient cells.

Question 136: Radiation-induced hypothyroidism is a common late effect of radiation to which anatomic region?

Abdomen below the diaphragm
Neck, including fields used for head and neck cancers or lymphoma (Correct answer)
Pelvis
Chest only below the clavicles

Correct answer: Neck, including fields used for head and neck cancers or lymphoma

The thyroid gland sits in the neck and receives significant dose during radiation for head and neck cancers, Hodgkin lymphoma, and medulloblastoma, leading to hypothyroidism in up to 50% of patients.

Question 137: The dose-limiting toxicity of vincristine is:

Myelosuppression
Peripheral neurotoxicity (Correct answer)
Nephrotoxicity
Cardiotoxicity

Correct answer: Peripheral neurotoxicity

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

Question 138: During a routine follow-up visit, the family caregiver of a patient with advanced cancer appears exhausted and tearful, stating 'I can't do this anymore.' Which of the following best represents the oncology NP's priority response?

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

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

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

Question 139: 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?

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

Correct answer: Low-dose systemic opioids

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

Question 140: Radiation-induced mucositis in the oral cavity is best managed with:

Prophylactic antifungals only
Frequent saline rinses, pain assessment, and nutritional support (Correct answer)
Corticosteroid mouthwash as monotherapy
Antibiotics regardless of infection signs

Correct answer: Frequent saline rinses, pain assessment, and nutritional support

Saline rinses maintain oral hygiene, regular pain assessment guides analgesic escalation, and nutritional support prevents the weight loss associated with mucositis.

Question 141: In breast-conserving surgery (lumpectomy) for breast cancer, which additional procedure is performed to assess locoregional lymph node involvement with minimal morbidity?

Complete axillary lymph node dissection (ALND) in all patients
No nodal assessment — imaging suffices
Sentinel lymph node biopsy (SLNB) (Correct answer)
CT-guided fine-needle aspiration of palpable nodes only

Correct answer: Sentinel lymph node biopsy (SLNB)

SLNB is the standard nodal staging procedure for clinically node-negative breast cancer patients undergoing lumpectomy. By mapping lymphatic drainage to identify the first (sentinel) node(s), SLNB accurately predicts axillary nodal status while avoiding the lymphedema risk of complete ALND.

Question 142: 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)
Thrombotic thrombocytopenic purpura (TTP)
Disseminated intravascular coagulation (DIC) (Correct answer)
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 143: Which serum tumor marker, when significantly elevated at diagnosis of a testicular mass, is most specific for non-seminomatous germ cell tumors (NSGCTs)?

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

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 144: Informed consent for clinical trial participation must include which elements specific to research, beyond standard clinical care consent?

Guarantee of treatment benefit based on Phase I data
Only the principal investigator's contact information
Insurance billing codes for the experimental intervention
Voluntary nature of participation, right to withdraw, foreseeable risks/benefits, and availability of alternative treatments (Correct answer)

Correct answer: Voluntary nature of participation, right to withdraw, foreseeable risks/benefits, and availability of alternative treatments

Research informed consent must include (per 45 CFR 46 and ICH-GCP): a statement that the study involves research, foreseeable risks and benefits, alternative procedures, confidentiality protections, compensation for injury, contact information, and explicit statement that participation is voluntary with the right to withdraw without penalty.

Question 145: Which measurement best indicates that a patient is at high risk of imminent death (hours to days) in the inpatient palliative setting?

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

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 146: Radiation pneumonitis typically presents within which timeframe after thoracic radiation?

More than 2 years after treatment
Only during active treatment fractions
Within the first week of treatment
1–6 months after completion of radiation (Correct answer)

Correct answer: 1–6 months after completion of radiation

Radiation pneumonitis presents 1–6 months after thoracic irradiation with dyspnea, cough, and low-grade fever as inflammatory cytokines accumulate in irradiated lung.

Question 147: Proton beam therapy offers a dosimetric advantage over photon (X-ray) radiation because protons:

Are cheaper and widely available at all cancer centers
Deposit most of their energy at a specific depth (Bragg peak) with minimal exit dose (Correct answer)
Penetrate less deeply, protecting superficial structures
Are not effective against hypoxic tumors

Correct answer: Deposit most of their energy at a specific depth (Bragg peak) with minimal exit dose

The Bragg peak allows protons to release their energy at the tumor depth with virtually no exit dose, reducing radiation to tissues beyond the tumor.

Question 148: Which opioid is considered first-line for moderate-to-severe cancer pain according to the WHO analgesic ladder?

Codeine
Tramadol
Acetaminophen
Morphine (Correct answer)

Correct answer: Morphine

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

Question 149: The first round of chemotherapy for a 40-year-old man with acute lymphocytic leukemia is now complete. Which of the nurse's following assertions is false?

“A medium well steak is a good idea of a sumptuous meal”
“You can eat soft cheeses from pasteurized milk”
“You can enjoy the turkey on the day of thanksgiving party”
“Try eating sashimi in one of the famous Japanese restaurants around the city” (Correct answer)

Correct answer: “Try eating sashimi in one of the famous Japanese restaurants around the city”

Sashimi and other raw or undercooked fish should be avoided in a low bacteria diet due to the possibility of exposure to dangerous germs.

Question 150: A patient with cancer-related dyspnea refractory to oxygen is best treated with:

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

Correct answer: Low-dose opioids

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

Question 151: In febrile neutropenia, an absolute neutrophil count (ANC) below which threshold defines high-risk neutropenia?

< 2000 cells/mm³
< 500 cells/mm³ (Correct answer)
< 1500 cells/mm³
< 1000 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 152: Which action is central to the NURSE communication framework used in delivering serious news to cancer patients?

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

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

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

Question 153: A patient with multiple myeloma presents with severe back pain, lower extremity weakness, and urinary retention. Which oncologic emergency does this presentation suggest?

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

Correct answer: Spinal cord compression

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

Question 154: A patient with colorectal cancer reports taking high-dose antioxidant supplements (vitamins C and E, selenium) during chemotherapy. What is the evidence-based concern the oncology NP should communicate?

High-dose antioxidants may interfere with the oxidative mechanism by which some chemotherapy agents kill cancer cells, potentially reducing treatment efficacy (Correct answer)
High-dose antioxidants directly cause hepatotoxicity when combined with fluorouracil
High-dose antioxidants are safe and may protect normal tissue from chemotherapy side effects without any concerns
High-dose antioxidants significantly increase chemotherapy-induced nephrotoxicity

Correct answer: High-dose antioxidants may interfere with the oxidative mechanism by which some chemotherapy agents kill cancer cells, potentially reducing treatment efficacy

Many conventional chemotherapy agents (alkylating agents, anthracyclines, platinum compounds) and radiation exert cytotoxic effects partly through generation of reactive oxygen species (ROS). High-dose antioxidant supplementation during active treatment may theoretically neutralize these ROS, potentially reducing efficacy — a concern supported by mechanistic evidence and some observational data, leading ASCO and integrative oncology guidelines to recommend caution and avoidance of high-dose antioxidant supplements during active treatment.

Question 155: The ACS recommends that average-risk adults begin colorectal cancer screening at which age?

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

Correct answer: 45 years

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

Question 156: According to the TNM staging system, which descriptor indicates that cancer cells have spread to regional lymph nodes?

N1 (Correct answer)
M1
G2
T2

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 157: Anticipatory grief is best described as:

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

Correct answer: Grief experienced before an expected loss occurs

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

Question 158: Which antiemetic is most appropriate for opioid-induced nausea acting via the chemoreceptor trigger zone?

Dexamethasone
Metoclopramide
Prochlorperazine (Correct answer)
Ondansetron

Correct answer: Prochlorperazine

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

Question 159: Palliative sedation is ethically appropriate when:

Refractory symptoms cannot be controlled by other means near end of life (Correct answer)
Family members request it without patient consent
Pain scores exceed 7 at any point in treatment
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 160: 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 161: Which tumor suppressor gene is most commonly mutated in hereditary breast-ovarian cancer syndrome?

TP53
MLH1
APC
BRCA1/BRCA2 (Correct answer)

Correct answer: BRCA1/BRCA2

BRCA1 and BRCA2 mutations account for the majority of hereditary breast-ovarian cancer syndrome cases.

Question 162: Which antiemetic class is the MOST effective for preventing acute chemotherapy-induced nausea and vomiting (CINV) from highly emetogenic regimens?

Prochlorperazine alone
Lorazepam alone
Metoclopramide as monotherapy
5-HT3 receptor antagonists combined with NK1 antagonists and dexamethasone (Correct answer)

Correct answer: 5-HT3 receptor antagonists combined with NK1 antagonists and dexamethasone

Triple antiemetic prophylaxis with a 5-HT3 antagonist, NK1 antagonist (aprepitant), and dexamethasone is the guideline-recommended standard for highly emetogenic chemotherapy.

Question 163: A patient on CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone) presents with constipation, abdominal distension, and absent bowel sounds. Which agent is most likely responsible?

Cyclophosphamide causing hemorrhagic enteritis
Prednisone causing peptic ulcer disease
Vincristine causing autonomic neuropathy and paralytic ileus (Correct answer)
Doxorubicin causing mucosal damage and dysmotility

Correct answer: Vincristine causing autonomic neuropathy and paralytic ileus

Vincristine's neurotoxicity includes autonomic dysfunction, which can manifest as paralytic ileus requiring dose reduction or schedule adjustment.

Question 164: Which tool is specifically validated for assessing symptom burden in patients with advanced cancer across multiple symptom domains?

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

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

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

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 166: 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?

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

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.
