Introduction
The Certified Breast Care Nurse (CBCN) examination is a comprehensive
assessment designed to validate the specialized knowledge and clinical expertise of
registered nurses providing care across the breast cancer continuum. The purpose of
this exam is to ensure that practitioners possess the critical thinking skills necessary
for decision-making in screening, diagnosis, treatment planning, and survivorship.
This assessment utilizes a combination of foundational multiple-choice questions and
,complex clinical scenarios to evaluate a candidate’s ability to apply evidence-based
standards to real-world patient care. Nurses are tested on their proficiency in
managing physical and psychosocial symptoms, navigating legal and ethical
frameworks, and facilitating multidisciplinary coordination to improve patient
outcomes.
1. Which of the following is considered the most significant non-modifiable risk
factor for the development of breast cancer?
A. Obesity
B. Advancing age
C. Nulliparity
D. Sedentary lifestyle
🟢 Correct answer B. Advancing age
🔴 RATIONALE: While obesity and nulliparity are known risk factors, advancing age
is the most significant non-modifiable risk factor, as the incidence of breast cancer
increases significantly as a woman gets older.
2. A patient with a newly diagnosed T2, N1, M0 infiltrating ductal carcinoma asks
the nurse what the "N1" means. Which response is most accurate?
,A. The tumor is between 2 and 5 centimeters.
B. There is no evidence of distant metastasis.
C. Cancer has spread to movable ipsilateral axillary lymph nodes.
D. The cancer is confined to the breast tissue only.
🟢 Correct answer C. Cancer has spread to movable ipsilateral axillary lymph nodes.
🔴 RATIONALE: In the TNM staging system, N1 indicates that the cancer has spread
to movable, palpable ipsilateral axillary lymph node(s).
3. A post-menopausal patient is prescribed Anastrozole (Arimidex). The nurse
should prioritize educating the patient on which potential side effect?
A. Increased risk of uterine cancer
B. Venous thromboembolism
C. Decreased bone mineral density
D. Cardiac cardiomyopathy
🟢 Correct answer C. Decreased bone mineral density
🔴 RATIONALE: Aromatase inhibitors like anastrozole suppress estrogen levels in
post-menopausal women, which significantly increases the risk of osteoporosis and
bone fractures.
, 4. Which imaging modality is most appropriate for the initial screening of a 25-
year-old woman with a palpable, mobile, non-tender breast mass?
A. Diagnostic mammography
B. Breast MRI with contrast
C. Ultrasound
D. Thermography
🟢 Correct answer C. Ultrasound
🔴 RATIONALE: In women under age 30, breast tissue is typically dense, making
mammography less effective; ultrasound is the preferred initial tool to differentiate
between a solid mass and a fluid-filled cyst.
5. A patient undergoing external beam radiation therapy for breast cancer
develops brisk erythema and moist desquamation in the axillary fold. This
should be documented as which grade of skin toxicity?
A. Grade 1
B. Grade 2
C. Grade 3
D. Grade 4
