The receptor rules and treatments that recur on the CBCN. Skim before test day, then prove it with practice.
Exam facts
- 165 questions (125 scored), 3 hours
- Biggest areas: Nursing Practice (28%), Coordination of Care (26%)
Receptor status drives treatment
- ER/PR positive → endocrine therapy: tamoxifen (often
premenopausal), aromatase inhibitors (postmenopausal) - HER2 positive → HER2-targeted therapy (e.g., trastuzumab)
- Triple-negative → chemotherapy is the mainstay
Surgery & nodes
- Sentinel lymph node biopsy first for clinically node-negative early disease
- Protect the at-risk arm after axillary surgery to reduce lymphedema (avoid trauma, BPs, venipuncture)
Risk & screening
- Strong family history of breast/ovarian cancer → genetic counseling and possible BRCA1/2 testing
- Staging follows the TNM system (tumor, nodes, metastasis)
