Exam 2 Flashcards
What is breast tissue composed of?
glandular tissue in 15-20 lobes, suspensory ligaments (cooper’s), fat and adipose tissue
Axillary lymph nodes
central, pectoral, subscapular, lateral
supernumerary nipple
extra nipple along mammary ridge
tanner stage 1
pre-adolescent, elevation of nipple
tanner stage 2
breast bud stage, elevation of breast and nipple, enlargement of areola
tanner stage 3
further enlargement of breast and areola, menarchy
tanner stage 4
projection to form a second mound above the level of breast, menarchy
tanner stage 5
mature stage, projection of nipple only/areola recedes to level of breast
breast cancer risk factors
female over 50, personal and family history, BRCA 1/2 mutation, previous breast irradiation, menarche 50
breast cancer lifestyle risk factors
no kids or first kid after 30, long term hormone replacement therapy, alcohol 2-5 drinks daily, obesity, high fat diet, physical inactivity, not breast feeding
how long should a thorough breast exam take
3 min/breast
if lump is present what should be recorded
location, size, shape, consistency, mobility, distinctness, nipple, overlying skin color, tenderness, lymphadenopathy
gynecomastia
enlargement of flat disc of undeveloped breast tissue underneath male nipple
fibroadenomas
in age 15-25, usually single but can be multiple, well delineated, mobile, usually nontender, usually benign tumor
fibrocystic breast disease
age 30-50, regress after menopause except with estrogen therapy, round, well delineated, mobile, usually tender, lots of discomfort, single or mobile
Breast cancer
age 30 and older, most common in over 50, usually singular, irregular or stellate, firm or hard, not clearly delineated, can be fixed to skin or underlying tissues, usually nontender, usually ductal
peau d’or·ange
edema of breast, a pitted or dimpled appearance of the skin, especially as characteristic of some cases of breast cancer or due to cellulite
nipple retraction
suspensory ligament tightened up, possibly from breast cancer
Manubriosternal angle/angle of louis
important landmark for heart and lungs, site of trachea splitting, corresponds with the top of the heart, distinct bony ridge hooked to second rib
right lung fissures
oblique and horizontal
left lung fissures
oblique fissure
visceral pleurae
lines lungs
parietal pleurae
lines chest wall
functions of the lungs
supply O2 for energy production, remove CO2 as a waste product, maintain acid/base balance of arterial blood, maintain heat exchange
hypercapnia
increased CO2 in the blood increases breathing
hypoxemia
increased respirations due to an abnormally low concentration of oxygen in the blood
hypoventilation
low RR causes CO2 to build up –> respiratory acidosis
hyperventilation
rapid RR, low concentration of CO2
hacking cough is a sign of?
pneumonia
rust colored sputum
TB or pneumococcal pneumonia
frothy pink sputum
pulmonary edema
hemoptysis
coughing up blood due to TB, pulmonary embolus or heart failure, mitral valve stenosis due to increased pulmonary venous congestion (most common cardiac cause), pulmonary infarction, ruptured vessel
barrel chest is a sign of?
emphysema
Pectus excavatum
depressed breast bone, only an issue if it blocks lung expansion
Pectus carinatum
protruding breast bone
Kyphosis
tends to happen with older people because of osteoperosis/break down of spinal column, can affect ability to hear their breath sounds
scoliosis
sideways curvature of the spine
Anteroposterior: transverse diameter
1:2
coastal angle
should be
pink puffer
COPD, emphysema, chronic bronchitis, pink complexion + shortness of breath + tripod position
blue bloater
cyanosis, decreased capacity of lungs, right sided heart failure, COPD
tachypnea
> 20 RR, rapid breathing due to exercise, fever or acidotic
Kussmual
deeper rapid breathing, associated with metabolic acidosis
Cheyene-Stokes
respirations wax/wayne in a regular pattern, periods of apnea
where to palpate for symmetric expansion
T9 or T10
Tactile fremitus
Sound is conducted better through a dense or solid structure than porous so anything that increase density of lung will increase fremitus
Increased fremitus could be a sign of
pneumonia
decreased fremitus could be a sign of
obstructive bronchitis
bronchovesicular sounds
Inspiration = expiration, heard mid chest and between scapula
vesicular sounds
soft and low pitched, heard on most of lung surface, Inspiration > expiration
Bronchophony
tactile fremitus is abnormally clear rather than muffled, could be caused by the solidification of lung tissue (lung cancer) or fluid in the alveoli (pneumonia)
Egophony
E to A changes, increased resonance often caused by lung consolidation and fibrosis, could indicate pneumonia
Whispered Pectoriloquy
louder clear whispered “99“ rather than faint or absent sound, could be a sign of pneumonia or cancer
infants have a rounded thorax until?
age 6
infants breath through nose rather than mouth until
age 3 months
infant RR
30-40 breaths / min
infants have bronchovesicular sounds in peripheral lung field until
age 6
older adult chest changes…
increased AP:transverse, kyphosis, compensates by holding head extended and tilted back, decreased chest expansion, fatigue easily
atelectasis
partial or complete collapse of the lung usually due to anesthesia
atelectasis signs
trachea may be shifted towards involved side, absent tactile fremitus, dull percussion over affected area, absent breath sounds
Consolidation (pneumonia) signs
trachea is midline, increased tactile fremitus over affected area, dull percussion, bronchial breath sounds, late inspiratory crackles over involved area
bronchitis signs
trachea is midline, normal tactile fremitus, resonant percussion, vesicular breath sounds, possibly scattered coarse crackles or wheezes or rhonchi
emphysema
damaged alveoli
emphysema signs
trachea is midline, decreased tactile fremitus bc alveoli can’t get the air out so more trapped in lungs, hyperresonant percussion, decreased breath sounds to absent, possible scattered crackles, wheezes and rhonchi
bronchitis
inflammation of lining of bronchial tubes
pneumonia
fluid filled, infection of alveoli
asthma signs
trachea is midline, decreased tactile fremitus, resonant or hyperresonant percussion, breath sounds obscured by wheezes, possible crackles
asthma
Constriction in trachiobronchial tree & edema & mucus & bronchospasm, lungs will over inflate during asthma attack
pleural effusion
A buildup of fluid between the tissues that line the lungs and the chest, collapses the alveoli
pleural effusion signs
trachea shifted toward opposite side, decreased to absent tactile fremitus, dull to flat percussion, decreased to absent breath sounds, possible pleural friction rub
pneumothorax
collapsed lung usually due to injury - either air leaking into pleural space or a leak in the chest wall
pneumothorax signs
trachea shifted toward opposite side, decreased tactile fremitus due to pleural air, hyperresonant percussion, decreased to absent breath sounds, possible pleural rub
