INTRODUCTION
The purpose of this comprehensive assessment is to evaluate the clinical proficiency
and theoretical knowledge of nurses specializing in oncology. This exam assesses a
broad spectrum of skills, ranging from the foundational biology of cancer to advanced
pharmacological interventions and ethical decision-making. The assessment features
,a combination of knowledge-based multiple-choice questions and complex scenario-
based inquiries designed to mirror real-world clinical challenges. By emphasizing
critical thinking and the application of evidence-based practice, this exam ensures
that practitioners are prepared to provide high-quality, patient-centered care.
Candidates must demonstrate competence in symptom management, treatment
toxicities, and the psychosocial support of patients and families throughout the cancer
continuum.
SECTION ONE: QUESTIONS 1–100
1. A patient with a history of tobacco use and chronic alcohol consumption is
diagnosed with squamous cell carcinoma of the esophagus. Which risk factor is
most significantly associated with the development of this specific histology in
the upper two-thirds of the esophagus?
A. Gastroesophageal reflux disease (GERD)
B. Barrett’s esophagus
C. Combined use of tobacco and alcohol
D. High-fat dietary intake
🟢 C. Combined use of tobacco and alcohol
,🔴 RATIONALE: While GERD and Barrett’s esophagus are primary risk factors for
adenocarcinoma of the distal esophagus, the synergistic effect of tobacco and
alcohol consumption is the leading risk factor for squamous cell carcinoma,
particularly in the proximal and middle thirds of the esophagus.
2. A nurse is reviewing the pathology report of a patient with breast cancer. The
report indicates the tumor is "T2, N1, M0." How should the nurse interpret the
"N1" component of this staging?
A. The tumor has spread to distant organs.
B. There is metastasis to movable ipsilateral axillary lymph nodes.
C. The lymph nodes are fixed and matted.
D. No regional lymph node involvement is detected.
🟢 B. There is metastasis to movable ipsilateral axillary lymph nodes.
🔴 RATIONALE: In the TNM staging system for breast cancer, N1 indicates
involvement of 1 to 3 regional lymph nodes that are typically movable. N0 indicates
no node involvement, and M0 indicates no distant metastasis.
3. Which of the following laboratory values is the most critical to monitor for a
patient receiving high-dose methotrexate?
, A. Serum potassium
B. Serum creatinine
C. Hemoglobin levels
D. Serum glucose
🟢 B. Serum creatinine
🔴 RATIONALE: Methotrexate is primarily excreted by the kidneys and can cause
nephrotoxicity. High-dose methotrexate requires rigorous hydration and monitoring of
serum creatinine to ensure clearance and prevent acute kidney injury, which would
further delay drug excretion and increase systemic toxicity.
4. During a chemotherapy infusion of a vesicant agent, the patient complains of a
burning sensation at the peripheral IV site. What is the nurse's immediate
priority action?
A. Slow the infusion rate and apply a warm compress.
B. Aspirate the remaining drug from the catheter.
C. Stop the infusion immediately.
D. Notify the oncologist.
🟢 C. Stop the infusion immediately.
