WITH DETAILED QUESTIONS AND CORRECT
ANSWERS GRADED A+| CHAMBERLAIN
UNIVERSITY
1. A nurse is reviewing the internal structure of the breast.
Which components primarily comprise the breast tissue?
A. Skeletal muscle and dense ligamentous tissue
B. Fibrous, glandular, and adipose tissues
C. Lactiferous ducts and smooth muscle
D. Pectoralis major muscle and connective fascia
Correct Answer: B
Rationale: The breast tissue is structurally composed of
glandular tissue (which produces milk), fibrous tissue (including
Cooper's ligaments for support), and adipose tissue (which
provides the bulk of the breast volume).
,2. During a clinical breast examination, why is it essential for
the advanced practice nurse to pay special attention to the
upper outer quadrant of the breast?
A. It contains the largest amount of adipose tissue.
B. It is the most frequent site of breast tumor development.
C. Cooper's ligaments attach exclusively in this region.
D. It is the only area containing lactiferous ducts.
Correct Answer: B
Rationale: The upper outer quadrant (including the Axillary Tail of
Spence) contains a high concentration of glandular tissue and is
the location where the majority of breast malignancies are
detected.
3. When evaluating the axillary lymph system during a
physical assessment, which primary groups of nodes should
the clinician palpate?
A. Central, lateral, pectoral, and subscapular
B. Supraclavicular, sternal, lateral, and deep cervical
,C. Anterior, posterior, deep axillary, and epitrochlear
D. Inguinal, central, pectoral, and brachial
Correct Answer: A
Rationale: The four primary groups of axillary lymph nodes
assessed during a breast exam are the central axillary (high in the
axilla), lateral (along the humerus), pectoral/anterior (along the
lateral edge of the pectoralis major), and subscapular/posterior
(along the lateral border of the scapula).
4. A patient presents with a localized skin infection on her
right forearm. Which lymphatic finding would the clinician
expect upon examination of the axilla?
A. Contralateral axillary lymph node enlargement
B. Ipsilateral axillary lymph node enlargement
C. Bilateral supraclavicular lymph node enlargement
D. Generalized inguinal lymphadenopathy
, Correct Answer: B
Rationale: Lymphatic drainage from the upper extremity flows
toward the ipsilateral (same side) axillary lymph nodes. An
infection in the right arm leads to enlargement of the right axillary
nodes.
5. A 9-year-old girl expresses anxiety because her peers are
wearing bras, but she has not noticed any breast growth yet.
What is the most appropriate response by the nurse
practitioner?
A. "You will likely start your menstrual period before your breasts
begin to grow."
B. "Breast development usually begins between 8 and 10 years of
age, so your timing is normal."
C. "We should order a hormone panel immediately to check for
delayed puberty."
D. "You should expect rapid breast growth within the next month."
Correct Answer: B
