Ambulatory Care Nursing Certification Exam 2026: Comprehensive
Professional Practice Test — Patient Assessment, Chronic Disease
Management, Preventive Care, Medication Safety, Care Coordination
& Clinical Decision-Making — 190 Multiple-Choice Questions with
Answers & Detailed Rationales
SECTION I: CARE CONTINUUM — BREAST HEALTH, SCREENING, AND EARLY DETECTION
(Questions 1–50)
Question 1
A 52-year-old patient presents for a routine wellness visit. She reports no breast symptoms
but has a strong family history of breast cancer in her mother and sister. According to
current guidelines, which screening recommendation is most appropriate for this patient?
A. Annual mammography beginning at age 40
B. Mammography every 2 years beginning at age 50
C. Annual mammography and clinical breast exam beginning at age 40
D. No screening until age 55 unless symptoms develop
Correct Answer: A
Explanation: Guidelines recommend annual mammography for women at average risk
starting at age 40; this patient's family history further supports early and regular screening.
Question 2
During a clinical breast exam, the nurse palpates a firm, mobile, well-circumscribed mass in
the upper outer quadrant of a 34-year-old patient's breast. The patient reports the mass
feels tender before menses. What is the most likely diagnosis?
A. Fibroadenoma
B. Invasive ductal carcinoma
,C. Fibrocystic changes
D. Phyllodes tumor
Correct Answer: C
Explanation: Fibrocystic breast changes commonly present as tender, mobile masses that
fluctuate with hormonal cycles; this pattern is characteristic of benign fibrocystic disease.
Question 3
A 47-year-old patient undergoes screening mammography. The radiologist assigns a BI-RADS
score of 4. What does this classification indicate?
A. Negative, routine screening recommended
B. Benign finding, no further action needed
C. Suspicious abnormality, biopsy should be considered
D. Highly suggestive of malignancy, immediate treatment required
Correct Answer: C
Explanation: BI-RADS 4 indicates a suspicious abnormality warranting tissue sampling; BI-
RADS 5 indicates high suspicion for malignancy.
Question 4
A 29-year-old patient asks about breast self-awareness. Which teaching point should the
nurse emphasize?
A. Perform self-breast exams on the same day each month
B. Know what is normal for your breasts and report changes promptly
C. Self-exams replace the need for clinical breast exams
,D. Only perform self-exams if you have a family history of breast cancer
Correct Answer: B
Explanation: Breast self-awareness emphasizes recognizing normal breast appearance and
texture, enabling prompt reporting of changes rather than rigid technique or schedule.
Question 5
A 62-year-old patient with a history of lobular carcinoma in situ (LCIS) asks about her risk of
developing invasive breast cancer. What is the most accurate response?
A. LCIS does not increase cancer risk
B. LCIS indicates a 1–2% lifetime risk increase
C. LCIS confers a 20–30% lifetime risk of invasive cancer
D. LCIS requires immediate bilateral mastectomy
Correct Answer: C
Explanation: LCIS is a marker of increased risk, conferring approximately 20–30% lifetime risk
of invasive breast cancer, warranting enhanced surveillance.
Question 6
A 44-year-old patient has dense breast tissue noted on mammography. How does breast
density affect cancer risk and screening?
A. Dense tissue decreases risk but improves mammogram accuracy
B. Dense tissue increases risk and may reduce mammogram sensitivity
C. Dense tissue has no effect on risk or imaging
D. Dense tissue requires MRI instead of mammography for all patients
, Correct Answer: B
Explanation: Dense breast tissue increases cancer risk and can mask tumors on
mammography, potentially requiring supplemental imaging such as ultrasound or MRI.
Question 7
A patient with a BRCA1 mutation asks about risk-reduction strategies. Which intervention
provides the greatest reduction in breast cancer risk?
A. Annual mammography starting at age 25
B. Prophylactic bilateral mastectomy
C. Chemoprevention with tamoxifen
D. Increased physical activity and dietary changes
Correct Answer: B
Explanation: Prophylactic bilateral mastectomy reduces breast cancer risk by approximately
90–95% in BRCA mutation carriers, the most significant risk-reduction intervention available.
Question 8
A 38-year-old patient presents with a spontaneous, unilateral, bloody nipple discharge. What
is the priority nursing action?
A. Reassure the patient this is a benign finding
B. Document and schedule routine follow-up in 6 months
C. Refer for diagnostic evaluation to rule out malignancy
D. Advise the patient to avoid nipple stimulation
