1. A 46-year-old woman presents for evaluation of a newly palpable
breast mass. She reports that the mass was initially tender before
menstruation but has persisted for three menstrual cycles. On
examination, the lesion is firm, mobile, and approximately 2 cm in
diameter. There is no skin retraction or palpable axillary
lymphadenopathy. Which nursing interpretation is MOST
appropriate?
A. The mass is most likely malignant because it is firm and persistent.
B. The mass is most likely a fibroadenoma because it is mobile.
C. The physical examination alone cannot reliably distinguish a benign
from malignant breast lesion.
D. The absence of lymphadenopathy excludes invasive breast cancer.
Answer: C.
Rationale: A breast mass cannot be reliably characterized as benign or
malignant solely from palpation. Mobility and tenderness may suggest
a benign process, but malignancies can also be mobile or painless,
particularly early in their course. Persistent or clinically concerning
masses require appropriate diagnostic evaluation, which may include
diagnostic mammography, ultrasound, and tissue sampling depending
1
,on age and clinical circumstances. The nurse should avoid falsely
reassuring the patient based solely on physical characteristics.
2. A patient asks the breast care nurse why mammography
commonly uses both craniocaudal and mediolateral oblique views.
Which explanation is BEST?
A. The two views determine whether a tumor is hormone receptor
positive.
B. The two views provide complementary visualization of breast tissue
and improve localization and detection of abnormalities.
C. The two views are required only when breast cancer is already
diagnosed.
D. The second view is used primarily to determine whether a biopsy is
required.
Answer: B.
Rationale: Craniocaudal and mediolateral oblique views provide
complementary perspectives of the breast and allow radiologists to
evaluate tissue from different orientations. The mediolateral oblique
view also includes portions of the upper outer breast and axillary
region. Imaging findings determine whether additional diagnostic
evaluation is appropriate; mammographic views themselves do not
determine tumor receptor status.
3. A 52-year-old patient has a screening mammogram reported as
BI-RADS 5. She asks the nurse, “Does this mean I definitely have
breast cancer?” Which response is MOST accurate?
A. “Yes. BI-RADS 5 means the mammogram has already confirmed
cancer.”
B. “No. BI-RADS 5 means the finding is highly suspicious and tissue
2
,diagnosis is generally recommended.”
C. “No. BI-RADS 5 means the finding is probably benign and can be
observed.”
D. “Yes. BI-RADS 5 specifically identifies invasive ductal carcinoma.”
Answer: B.
Rationale: BI-RADS 5 indicates a finding that is highly suspicious for
malignancy and warrants appropriate tissue diagnosis. Imaging
cannot establish the definitive histologic diagnosis of breast cancer.
Pathologic examination of tissue is required for confirmation. BI-
RADS categories guide management and follow-up; they do not
substitute for pathology.
4. A woman with a newly diagnosed invasive breast carcinoma has
pathology showing estrogen receptor-positive and progesterone
receptor-positive disease with HER2-negative status. Which
statement best explains the clinical significance of these biomarkers?
A. They determine the patient's exact TNM stage.
B. They provide information about tumor biology and help guide
systemic treatment decisions.
C. They determine whether breast-conserving surgery is technically
possible.
D. They establish whether the tumor is metastatic.
Answer: B.
Rationale: ER, PR, and HER2 are important biomarkers that
characterize breast tumor biology and have major therapeutic
implications. Hormone receptor-positive tumors may respond to
endocrine therapy, while HER2-positive disease may benefit from
HER2-directed therapy. Biomarkers do not independently establish
anatomic TNM stage or determine whether disease is metastatic.
3
, 5. A patient with newly diagnosed breast cancer says, “My tumor is
estrogen-receptor positive, so estrogen must have caused my
cancer.” Which response by the nurse is BEST?
A. “Yes, estrogen receptor positivity proves that estrogen caused the
cancer.”
B. “ER positivity means the cancer cells have receptors that can respond
to estrogen signaling; it does not prove estrogen was the sole cause.”
C. “ER positivity means the tumor cannot grow without estrogen.”
D. “ER positivity means chemotherapy will not be effective.”
Answer: B.
Rationale: ER positivity indicates expression of estrogen receptors by
tumor cells and identifies a biologic pathway that can be
therapeutically targeted with endocrine therapy. It does not establish a
single causative factor. ER-positive disease can have complex
molecular and environmental contributors. ER status also does not
automatically determine whether chemotherapy is appropriate.
6. A patient with early-stage breast cancer undergoes breast-
conserving surgery followed by radiation therapy. Which
explanation best describes the purpose of breast irradiation in this
setting?
A. To eliminate all possible circulating tumor cells throughout the body
B. To reduce the risk of local recurrence in the treated breast
C. To replace the need for pathologic assessment of surgical margins
D. To prevent all future cancers
Answer: B.
Rationale: Radiation therapy following breast-conserving surgery is
commonly used to reduce the risk of local recurrence in the remaining
