Introduction
This comprehensive examination is designed to assess the advanced knowledge and clinical judgment
required for the Advanced Oncology Certified Nurse Practitioner (AOCNP) certification. The questions
encompass a wide range of topics, from foundational cancer biology and genetics to complex
treatment modalities, symptom management, and the psychosocial aspects of patient care. This
assessment utilizes a multiple-choice and scenario-based format to evaluate critical thinking and
decision-making skills in real-world clinical settings. By emphasizing practical application and
evidence-based practice, this exam serves as a crucial tool to prepare candidates for the rigors of the
AOCNP board exam and to ensure the delivery of high-quality, patient-centered oncology care.
SECTION ONE: QUESTIONS 1-100
1. A 62-year-old patient with a history of chronic myelogenous leukemia (CML) is receiving
imatinib therapy. Which of the following side effects requires the most immediate intervention?
A. Periorbital edema
B. Nausea and diarrhea
C. Muscle cramps
D. Elevated liver enzymes
🟢 D. Elevated liver enzymes
🔴 Explanation: Imatinib can cause hepatotoxicity, which can be severe and potentially life-
threatening. Liver function tests must be closely monitored, and significant elevations may require
dose interruption or discontinuation to prevent hepatic failure. While periorbital edema, nausea,
diarrhea, and muscle cramps are common side effects, they are generally manageable and do not
represent the same level of immediate threat as severe hepatotoxicity.
2. Which of the following is the most important modifiable risk factor for the development of
bladder cancer?
A. Exposure to benzene
B. History of recurrent urinary tract infections
,C. Cigarette smoking
D. High-fat diet
🟢 C. Cigarette smoking
🔴 Explanation: Cigarette smoking is the single most important and modifiable risk factor for
bladder cancer, accounting for approximately 50% of cases. Carcinogens in tobacco smoke are
excreted in urine and directly damage the urothelium. While occupational exposure to chemicals
like benzene is a risk factor, smoking has a stronger and more widespread association. Recurrent
infections and diet play a much smaller role in the etiology of bladder cancer.
3. A patient with non-small cell lung cancer is started on pembrolizumab. The nurse practitioner
should educate the patient to report which of the following symptoms immediately?
A. Fatigue and mild anorexia
B. New-onset cough and fever
C. Pruritus and dry skin
D. Constipation and abdominal bloating
🟢 B. New-onset cough and fever
🔴 Explanation: New-onset cough and fever can be signs of pneumonitis, a serious and potentially
fatal immune-related adverse event (irAE) associated with checkpoint inhibitors like
pembrolizumab. Interstitial lung disease requires prompt evaluation and treatment, often with
corticosteroids. Other symptoms like fatigue, pruritus, and constipation are also common but are
not typically considered immediate, life-threatening emergencies.
4. A 55-year-old female with early-stage breast cancer is considering her surgical options. She
has a strong family history of breast cancer. What additional assessment is most critical for her
preoperative planning?
A. Baseline cardiac function
B. Genetic counseling and testing for BRCA mutations
C. Evaluation of her nutritional status
D. Assessment of her support system
🟢 B. Genetic counseling and testing for BRCA mutations
🔴 Explanation: Given her strong family history, identifying a BRCA mutation is critical. A positive
result would significantly alter her surgical options, as it may support a bilateral mastectomy to
reduce future cancer risk. It also has implications for family members and can guide future
surveillance strategies. While the other options are part of a comprehensive evaluation, they are not
as specifically critical for her surgical decision-making in this context.
5. A patient is receiving cisplatin-based chemotherapy. The nurse practitioner knows that which
of the following is the primary mechanism of cisplatin-induced nephrotoxicity?
A. Acute interstitial nephritis
B. Direct tubular cell injury and apoptosis
C. Prerenal azotemia from vomiting
D. Obstructive nephropathy
🟢 B. Direct tubular cell injury and apoptosis
,🔴 Explanation: Cisplatin is taken up by renal tubular cells where it causes direct cellular injury and
apoptosis (programmed cell death). This results in acute tubular necrosis. While vomiting can cause
prerenal azotemia, the primary mechanism is direct damage to the tubular epithelium. Acute
interstitial nephritis and obstructive nephropathy are not the classic mechanisms for this drug.
6. A 70-year-old male with prostate cancer is prescribed leuprolide. What is the most common
long-term adverse effect of this therapy that the NP should address?
A. Hypertension
B. Osteoporosis and increased fracture risk
C. Hepatotoxicity
D. Hyperglycemia
🟢 B. Osteoporosis and increased fracture risk
🔴 Explanation: Leuprolide is a GnRH agonist that causes a reduction in testosterone levels.
Chronic androgen deprivation therapy (ADT) leads to bone loss and significantly increases the risk
of osteoporosis and fractures, making it the most important long-term adverse effect to monitor
and manage. While fatigue, hot flashes, and metabolic changes can occur, bone health is the most
clinically significant long-term concern.
7. A patient with advanced ovarian cancer is being treated with a PARP inhibitor. Which of the
following is the most important baseline and ongoing monitoring parameter for this therapy?
A. Thyroid function tests
B. Complete blood count (CBC) with differential
C. Renal function tests
D. Serum electrolytes
🟢 B. Complete blood count (CBC) with differential
🔴 Explanation: PARP inhibitors can cause significant myelosuppression, including anemia,
thrombocytopenia, and neutropenia. Regular monitoring of the CBC is critical to detect these
potentially serious hematologic toxicities. The risk of myelodysplastic syndrome (MDS) and acute
myeloid leukemia (AML) is also a rare but serious concern that can be detected through monitoring
the CBC. While the other options are important, they are not as specifically tied to the primary,
most common toxicities of this drug class.
8. A patient is started on allopurinol prior to chemotherapy for a high-grade lymphoma. What is
the primary goal of this therapy?
A. To prevent acute kidney injury from tumor lysis syndrome
B. To treat hyperuricemia caused by chemotherapy
C. To prevent a hypersensitivity reaction to the chemotherapy
D. To increase the efficacy of the chemotherapeutic agents
🟢 A. To prevent acute kidney injury from tumor lysis syndrome
🔴 Explanation: Allopurinol is a xanthine oxidase inhibitor that reduces the production of uric acid.
In the context of high-grade lymphomas and other highly proliferative tumors, the rapid cell lysis
caused by chemotherapy can release large amounts of intracellular uric acid. This can lead to tumor
, lysis syndrome (TLS) and subsequent acute kidney injury. Allopurinol is used prophylactically to
prevent this complication by lowering uric acid levels.
9. In a patient with Hodgkin lymphoma, which of the following clinical findings is a classic B
symptom?
A. Persistent generalized lymphadenopathy
B. Unexplained weight loss of more than 10% body weight over 6 months
C. Splenomegaly
D. Pruritus without rash
🟢 B. Unexplained weight loss of more than 10% body weight over 6 months
🔴 Explanation: B symptoms are systemic signs of lymphoma and include unexplained fever >38°C,
drenching night sweats, and unexplained weight loss of >10% of body weight over 6 months. These
are important for staging and prognosis. While pruritus is a symptom associated with Hodgkin
lymphoma, it is not classified as a classic B symptom. Lymphadenopathy and splenomegaly are
signs of the disease but are not B symptoms.
10. A 48-year-old patient is diagnosed with colorectal cancer. The NP understands that which of
the following dietary factors has the strongest evidence for increasing the risk of this cancer?
A. High intake of red and processed meats
B. Low intake of fruits and vegetables
C. High intake of dietary fat
D. Low-calcium diet
🟢 A. High intake of red and processed meats
🔴 Explanation: A substantial body of epidemiological evidence strongly links a high intake of red
and processed meats to an increased risk of colorectal cancer. The mechanisms may involve
heterocyclic amines, polycyclic aromatic hydrocarbons, and N-nitroso compounds formed during
processing and cooking. While other dietary factors may play a role, the evidence for red and
processed meats is the strongest and most consistent.
11. A 65-year-old patient presents with progressive hoarseness and a history of smoking. The
initial imaging of choice to evaluate the larynx is:
A. Computed tomography (CT) of the neck with contrast
B. Magnetic resonance imaging (MRI) of the neck
C. Panendoscopy
D. Positron emission tomography (PET) scan
🟢 A. Computed tomography (CT) of the neck with contrast
🔴 Explanation: CT of the neck with contrast is the standard initial imaging modality for evaluating
suspected laryngeal cancer. It provides excellent detail of the laryngeal structures, cartilage
invasion, and cervical lymphadenopathy. While panendoscopy is the gold standard for direct
visualization and biopsy, it is an invasive procedure, not an imaging study. MRI is often used to
evaluate soft tissue extension, and PET/CT may be used for staging, but CT is typically the first
imaging step.
