AOCNP (ADVANCED ONCOLOGY CERTIFIED NURSE
PRACTITIONER) EXAM 300 ACTUAL QUESTIONS
AND CORRECT ANSWERS WITH RATIONALE
LATEST UPDATE ALREADY GRADED A+ ASSURED
PASS
The AOCNP (Advanced Oncology Certified Nurse Practitioner) exam is a
rigorous, psychometrically validated certification administered by the
Oncology Nursing Certification Corporation (ONCC) for nurse practitioners
specializing in adult oncology. The 3-hour, computer-based test consists of 165
multiple-choice questions covering five core domains, with a heavy emphasis
on cancer treatment, symptom management, and supportive care. Eligibility
requires either an oncology-focused NP program or general NP training with
additional oncology practice hours. Passing requires a scaled score of 55.
Certification is valid for four years, with renewal through professional
development, ensuring AOCNPs maintain excellence in comprehensive,
evidence-based oncology care.
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
Answer: C
Rationale: PD-L1 expression on tumor cells helps determine eligibility and the
expected response to immune checkpoint inhibitors, which are a form of
immunotherapy. A high PD-L1 expression level often indicates a patient is more
likely to benefit from these agents.
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
Answer: B
Rationale: Anthracyclines are known for their dose-dependent cardiotoxicity,
which can lead to cardiomyopathy and heart failure. Baseline and periodic
assessment of left ventricular ejection fraction (LVEF) is a standard monitoring
requirement to detect early cardiac dysfunction.
3. Tumor lysis syndrome is most commonly associated with:
A. Early-stage colon cancer
B. Hormonal therapy
C. High-grade lymphomas and leukemias
D. Radiation dermatitis
Answer: C
Rationale: Tumor lysis syndrome (TLS) is a metabolic emergency that occurs
when a large number of cancer cells are destroyed rapidly, releasing their contents
into the bloodstream. This is most frequently seen in hematologic malignancies
like high-grade lymphomas and acute leukemias due to their rapid proliferation and
high sensitivity to chemotherapy.
4. A patient on cisplatin reports tinnitus. The most appropriate action is:
A. Reassure the patient
B. Administer diuretics
C. Continue therapy unchanged
D. Evaluate for ototoxicity and notify the oncology team
Answer: D
Rationale: Cisplatin is a highly ototoxic chemotherapy agent that can cause
irreversible sensorineural hearing loss and tinnitus. Any new auditory symptom
warrants immediate evaluation and discussion with the oncology team about
potential dose modification or discontinuation.
5. Which laboratory finding is most consistent with the syndrome of inappropriate
antidiuretic hormone (SIADH) in a small cell lung cancer patient?
A. Elevated serum sodium
B. Decreased urine osmolality
C. Low serum sodium with high urine osmolality
D. Elevated serum potassium
Answer: C
Rationale: SIADH causes water retention due to excessive antidiuretic hormone
release, leading to dilutional hyponatremia. In SIADH, serum sodium is low while
,urine osmolality is inappropriately high, indicating the kidneys are not diluting
urine as they should.
6. The AOCNP is managing a patient with febrile neutropenia. Which organism is
the most common cause of bacteremia in this setting?
A. Candida albicans
B. Staphylococcus aureus
C. Coagulase-negative staphylococci
D. Pseudomonas aeruginosa
Answer: C
Rationale: Coagulase-negative staphylococci, particularly Staphylococcus
epidermidis, are the most frequently isolated organisms in febrile neutropenic
patients, largely due to their association with central venous catheter infections.
While Pseudomonas and other gram-negatives are also important, coagulase-
negative staphylococci are the most common overall.
7. A breast cancer patient on tamoxifen should be monitored for:
A. Bone density loss
B. Endometrial hyperplasia and thromboembolism
C. Nephrotoxicity
D. Cardiotoxicity
Answer: B
Rationale: Tamoxifen is a selective estrogen receptor modulator that has estrogenic
effects on the uterus, increasing the risk of endometrial hyperplasia and
endometrial cancer. It also increases the risk of venous thromboembolic events, so
patients should be counseled on signs of deep vein thrombosis and pulmonary
embolism.
8. Which targeted therapy is associated with acneiform rash as a common dose-
limiting side effect?
A. Trastuzumab
B. Rituximab
C. Erlotinib
D. Bevacizumab
Answer: C
Rationale: Erlotinib is an epidermal growth factor receptor (EGFR) tyrosine kinase
inhibitor. EGFR is expressed in the skin and hair follicles, and its inhibition leads
to an acneiform rash that is a very common and often dose-limiting toxicity
requiring symptom management and sometimes dose reduction.
, 9. A patient with metastatic colorectal cancer on FOLFOX develops cold-induced
paresthesia. This is most likely due to:
A. 5-fluorouracil
B. Leucovorin
C. Oxaliplatin
D. Bevacizumab
Answer: C
Rationale: Oxaliplatin is a platinum-based chemotherapy that causes a unique form
of peripheral neuropathy characterized by cold-induced dysesthesia and paresthesia
in the hands, feet, and perioral area. This is a hallmark toxicity of oxaliplatin and is
exacerbated by exposure to cold temperatures.
10. Which medication is the preferred prophylactic agent for preventing tumor
lysis syndrome in a high-risk patient?
A. Allopurinol
B. Rasburicase
C. Sodium bicarbonate
D. Furosemide
Answer: B
Rationale: Rasburicase is a recombinant urate oxidase that rapidly converts uric
acid to allantoin, a more soluble compound that is easily excreted. It is the
preferred agent for high-risk tumor lysis syndrome because it works faster and is
more effective than allopurinol, which only prevents new uric acid formation
rather than reducing existing levels.
11. A patient receiving trastuzumab for HER2-positive breast cancer must have
routine monitoring of:
A. Liver function
B. Renal function
C. Left ventricular ejection fraction
D. Electrolytes
Answer: C
Rationale: Trastuzumab, a monoclonal antibody targeting HER2, is associated with
cardiotoxicity, particularly left ventricular dysfunction and heart failure. Routine
monitoring of LVEF via echocardiogram or MUGA scan is mandatory before,
during, and after treatment to detect early declines in cardiac function.
12. Which symptom is a hallmark of spinal cord compression in a cancer patient?
A. Headache and photophobia
