Health Assessment Chp 17 Flashcards
The breast is composed of (3 things)
Glandular tissue, fibrous tissue, including suspensory ligaments, and adipose tissue
What is glandular tissue and its purpose?
15-20 lobes radiating from the nipple and these are composed of lobules which contain clusters of alveoli that produce milk.
What is the tail of spence?
Cone shaped breast tissue that projects up into that axilla, close the pectoral group of axillary lymph nodes
The site of most breast tumors?
Upper outer quadrant
Where are the breast located?
Anterior to the Pectoralis major and serratus anterior muscles. Between the 2nd and 6th ribs and extending from the side of the sternum to the midaxillary line.
The breast lymphatic drains ___% of lymph into ____
75%, ipsilateral axillary nodes
Four groups of axillary nodes in the breast?
Central axillary nodes, pectoral (anterior), subscapular (posterior), lateral
Central axillary nodes
High up in the middle of the axilla, over the ribs and serratus anterior muscle. These receive lymph from the other three groups of nodes
Pectoral (anterior)
Along the lateral edge of the pectoralis major muscle, just inside the axillary fold.
Subscapular (posterior)
Along the lateral edge of the scapula, deep in the posterior axillary fold
Lateral group of lymph nodes
Along the humerus, inside the upper arm
From the central axillary nodes, drainage….
Flows up to the infraclavicular, and supraclavicular nodes.
A smaller amount of lymph drainage
Flows directly up to the infraclavicular group, or deep into the chest, or into the abdomen, or directly across the opposite breast
During embryonic life
Epidermal ridges or milk lines are present and curve down from the axilla to the groin bilaterally. The breast develops along the ridge over thorax, and the rest of the ridge atrophies. Occasionally a supernumerary nipple (extra nipple) persists and is visible somewhere along the track of the mammary ridge
At birth only breast structures present are
Lactiferous ducts within the nipple. No alveoli have developed. Little change occurs in puberty.
The onset of breast development occurs at an average age between
8&9 years for African American girls and by 10 in white girls. However, recent evidence shows an earlier onset of breast development in 7 year olds: 10.4% of white girls, 23.4% of non-Hispanic black girls and 15% of Hispanic girls
Early breast development is linked to
Greater body mass (BMI) ratings and reflects the rise in obesity in US children
Is it normal for one breast to grow faster than the other?
Yes, tenderness is common also
Tanner stages
- Preadolescent- only a small elevated nipple
- Breast bud stage- a small mound of breast and nipple develops; the aerial widens
- The breast and areole enlarge; the nipple is flush with the breast surface.
- The aerial and nipple from a secondary mound over the breast.
- Mature breast: only the nipple protrudes; the Areola is flush with the breast contour (the Areola may continue as a secondary mound in some normal women)
Tanner stages 2-5 takes an average of
3 years although the range is 1.5 to 6 years. During this time pubic hair develops, and axillary hair appears 2 years after the onset of pubic hair
The beginning of breast development precedes
Menarche (beginning of menstruation) by about 2 years.
Menarche occurs in breast development stage
3 or 4, usually just after peak of adolescent growth spurt around 12 years of age. This helps to assess the development of adolescent girls and increases their knowledge about their own development.
During pregnancy breast changes start
During the second month and are common early signs of pregnancy. Pregnancy stimulates the expansion of the ducal system and supporting fatty tissue and the development of true secretory alveoli. Thus the breast enlarge and feel more modular.
What happens to the nipples during pregnancy
They grow larger, darker, and more erectile
What happen to the areolae during pregnancy?
They become larger and darker as pregnancy progresses, and the tubercles become more prominent. The brown color fades after lactation, but the areolae never return to the original color
A 5-month pregnant woman comes in and complains of prominent venous patterns over enlarged breasts that are leaking a very thick, yellow fluid. How would you assess/ document this finding?
These are normal findings. (p 389)
During pregnancy, breasts expand the ducts system and supporting fatty tissue and development of the the secretory alveoli. This causes the breasts to be enlarged.
After the 4th month of pregnancy, colostrum (thick yellow precursor for milk) may be expressed.
Venous pattern is expected to be prominent over skin surface?
A 6-month pregnant woman is getting a routine breast assessment, what normal findings would you have?
Colostrum expressed
Enlarged nodular breasts
Larger, darker, more erectile nipples
Larger, darker areolae
Prominent tubercles
(p 389)
Describe the components of colostrum
Thick, yellow fluid
Precursor for milk
Same amount of protein and lactose as milk, practically no fat; rich in antibodies
Expected after 4th most until first few days after delivery (until milk is produced aka lactation)
A woman is postpartum and is questioning breastfeeding her new baby. What would you include in your discussion with her?
Since the baby is new born, she may be expelling colostrum for these first few days and that is normal; it is filled with antibodies so encourage breastfeeding
Lactation aka milk production, may take up to 3 days to start (1-3 days after delivery)
When it comes, it may be whitish color because emulsified fat and calcium caseinate
(P 389)
A postmenopausal woman complains of breast changes. Describe normal changed that would be assessed.
Decrease in estrogen and progesterone from ovaries, this causes atrophy in breast glandular tissue.
Fibrous connective tissue replaces the breast glandular tissue
Fat envelope atrophies ( decreases breast size and elasticity) giving the breasts a droopy look which is worsened by kyphosis
Internal structures more prominent and palpable
Decrease in axillary hair
(P 389)
Which spinal disorder affects an aging woman’s breasts?
Kyphosis
Drooping is accentuated by kyphosis in some older women (p 389)
A 49-year-old woman has done a BSE and comes into the hospital complaining of a new lump near her nipple she had not felt before menopause. She is a non-smoker, been losing weight since menopause, and has never had children/breastfed before. She is concerned about breast cancer, what should you tell her.
This is likely a normal finding because as an aging woman, her decreased breast size makes her inner structures more prominent. A breast lump may have been present for years is suddenly palpable.
Around the nipple, the lactiferous ducts more palpable and feel firm and stringy because of fibrosis and calcification.
