ADVANCED ONCOLOGY CERTIFIED NURSE PRACTITIONER (AOCNP) QUESTIONS AND CORRECT ANSWERS
WITH DETAILED RATIONALES | LATEST VERSION PDF
SECTION ONE: QUESTIONS 1–100
1. A 58-year-old patient with newly diagnosed non-small cell lung cancer asks about the role of PD-L1
testing. The AOCNP explains that PD-L1 testing primarily guides:
A. Surgical candidacy
B. Radiation dosing
C. Immunotherapy selection
D. Chemotherapy toxicity prediction
🟢 C. Immunotherapy selection
🔴 RATIONALE: PD-L1 expression on tumor cells predicts response to immune checkpoint inhibitors like
pembrolizumab, making it a critical biomarker for immunotherapy selection.
2. A patient receiving anthracycline therapy should undergo baseline evaluation of:
A. Renal function
B. Left ventricular ejection fraction (LVEF)
C. Pulmonary function tests
D. Thyroid function
🟢 B. Left ventricular ejection fraction (LVEF)
🔴 RATIONALE: Anthracyclines such as doxorubicin carry a significant risk of cumulative, dose-related
cardiomyopathy; baseline and periodic LVEF assessment is essential to monitor cardiac function.
3. Tumor lysis syndrome (TLS) is most commonly associated with:
A. Early-stage colon cancer
,B. Hormonal therapy
C. High-grade lymphomas and leukemias
D. Radiation dermatitis
🟢 C. High-grade lymphomas and leukemias
🔴 RATIONALE: TLS results from rapid tumor cell breakdown, releasing intracellular contents, and is most
frequently seen in highly proliferative hematologic malignancies like Burkitt lymphoma and acute leukemia.
4. A patient on cisplatin reports new-onset tinnitus. The most appropriate action is:
A. Reassure the patient that this is expected
B. Administer diuretics
C. Continue therapy unchanged
D. Evaluate for ototoxicity and notify the oncology team
🟢 D. Evaluate for ototoxicity and notify the oncology team
🔴 RATIONALE: Cisplatin is a known ototoxic agent; new tinnitus requires prompt evaluation to prevent
irreversible hearing loss and potential dose modification.
5. BRCA1 mutation increases risk primarily for:
A. Thyroid cancer
B. Breast and ovarian cancer
C. Colon cancer
D. Lung cancer
🟢 B. Breast and ovarian cancer
🔴 RATIONALE: BRCA1 and BRCA2 are tumor suppressor genes; pathogenic mutations confer significantly
increased lifetime risks for breast, ovarian, and other cancers.
6. A patient receiving an immune checkpoint inhibitor develops diarrhea. The priority assessment is:
A. Dietary intake
,B. Hemoglobin level
C. Severity and frequency of stools
D. Electrolytes only
🟢 C. Severity and frequency of stools
🔴 RATIONALE: Immune-mediated colitis can be severe; grading the severity and frequency of diarrhea is
critical for determining the appropriate management step, including potential corticosteroid therapy.
7. For extravasation of a vesicant chemotherapy agent, the first action is:
A. Remove the IV and apply pressure
B. Flush the line
C. Stop the infusion immediately
D. Apply heat universally
🟢 C. Stop the infusion immediately
🔴 RATIONALE: Immediate cessation of the infusion prevents further tissue damage by limiting the volume of
vesicant extravasated.
8. PSA screening discussions should include:
A. Universal recommendation
B. No risks
C. Shared decision-making
D. Mandatory annual screening
🟢 C. Shared decision-making
🔴 RATIONALE: Given the potential for overdiagnosis and overtreatment, shared decision-making is
recommended for PSA screening, discussing individual risks, benefits, and values.
9. SIADH in small cell lung cancer results in:
A. Hypernatremia
, B. Hyponatremia
C. Hyperkalemia
D. Hypocalcemia
🟢 B. Hyponatremia
🔴 RATIONALE: Syndrome of inappropriate antidiuretic hormone (SIADH) causes excessive water retention,
leading to dilutional hyponatremia.
10. The ECOG performance status assesses:
A. Tumor stage
B. Pain severity
C. Functional status
D. Nutritional intake
🟢 C. Functional status
🔴 RATIONALE: ECOG performance status measures a patient's functional ability and is a key prognostic
indicator, influencing treatment decisions and goals of care.
11. Sentinel lymph node biopsy is most relevant in:
A. Leukemia
B. Early-stage breast cancer
C. Multiple myeloma
D. Brain tumors
🟢 B. Early-stage breast cancer
🔴 RATIONALE: Sentinel lymph node biopsy is a standard surgical staging procedure for early-stage breast
cancer to determine nodal involvement without complete axillary dissection.
12. A patient with severe neutropenia (ANC < 500) presents with fever. The immediate priority is:
A. Administer antipyretics
