APEA PRACTICE QUESTIONS Women's Health Exam
Questions with well verified answers 2026!!!!
1. (Moderate Difficulty) Which of the following genetic mutations is most strongly associated with
hereditary breast cancer?
A) HER2
B) BRCA1 & BRCA2
C) TP53
D) PTEN - ANSWERS💫✔️-Answer: B) BRCA1 & BRCA2Explanation: Mutations in BRCA1 and BRCA2
increase the lifetime risk of breast cancer significantly. These genes function as tumor suppressors, and
their mutations lead to unchecked cell growth.
(High Difficulty) A 50-year-old woman presents with a firm, immobile, non-tender breast mass in the
upper outer quadrant. There is also peau d'orange skin dimpling. What is the most likely underlying
cause of the skin changes?
A) Inflammatory response
B) Lymphatic obstruction
C) Increased vascular permeability
D) Hormonal stimulation - ANSWERS💫✔️-B) Lymphatic obstruction
Explanation: Peau d'orange occurs due to cancerous invasion of dermal lymphatics, causing edema and
skin thickening.
(Moderate Difficulty) A postmenopausal woman with ER/PR-positive breast cancer is started on
anastrozole. What is the mechanism of action of this drug?
A) Selective estrogen receptor modulator
B) Estrogen receptor antagonist
C) Aromatase inhibitor
D) HER2 receptor inhibitor - ANSWERS💫✔️-C) Aromatase inhibitor
Explanation: Anastrozole inhibits aromatase, reducing estrogen synthesis in postmenopausal women,
which is crucial for ER/PR-positive breast cancer treatment.
, (High Difficulty) A patient with HER2-positive breast cancer is prescribed trastuzumab (Herceptin).
Which of the following adverse effects should be closely monitored?
A) Nephrotoxicity
B) Cardiotoxicity
C) Hepatotoxicity
D) Pulmonary fibrosis - ANSWERS💫✔️-B) Cardiotoxicity
Explanation: Trastuzumab can cause cardiomyopathy, leading to reduced left ventricular ejection
fraction (LVEF). Baseline and follow-up echocardiograms are recommended.
A premenopausal woman with ER/PR-positive breast cancer is started on tamoxifen. What is the most
serious potential adverse effect?
A) Osteoporosis
B) Endometrial cancer
C) Hypercalcemia
D) Pulmonary embolism - ANSWERS💫✔️-: B) Endometrial cancer
Explanation: Tamoxifen is a selective estrogen receptor modulator (SERM) that acts as an antagonist in
the breast but an agonist in the endometrium, increasing the risk of endometrial hyperplasia and cancer.
During a clinical breast exam, a 45-year-old patient is found to have a newly detected, firm, non-tender
breast mass with irregular borders in the upper outer quadrant. What is the next best step in evaluating
this mass?
A) Order a diagnostic mammogram and ultrasound
B) Schedule a follow-up exam in 6 months
C) Start empirical antibiotic therapy
D) Reassure the patient and advise self-monitoring - ANSWERS💫✔️-A) Order a diagnostic mammogram
and ultrasoundExplanation: Any new, persistent breast mass in a woman >40 years old should be
evaluated with diagnostic imaging (mammogram ± ultrasound). If findings are suspicious, a biopsy is
needed for definitive diagnosis.
Which of the following best describes the role of HER2 (human epidermal growth factor receptor 2) in
breast cancer pathophysiology?
A) It functions as a tumor suppressor gene, and its mutation leads to unchecked cell growth
