Monthly
What is the best time to perform a breast self-examination
Right after a menstrual period, when the breasts are the smallest, palpate while in shower
How many quadrants is the breast divided into
4
What is located in the upper outer quadrant
tail of Spence (cone shaped breast tissue that projects up into the axilla)
What is the most common site for breast tumors?
Upper outer quadrant
Which lung has 3 lobes?
Right
Posteriorly the location of C7 marks what?
apex of the lungs
Which lung is shorter?
Right (due to the liver being below it)
Which lung is more narrow?
The left( because the heart is part of this lung)
What are the lungs separated by?
fissures that run obliquely through the chest
What fissure crosses the 5th rib in the mid-axillary line and terminates at the 6th rib in midclavicular line?
oblique (major or diagonal)
What divides the upper, middle, and lower lobes of the right lung?
horizontal (minor) fissure
The total volume of air exhaled is known as?
Forced Vital Capacity (FVC)
Normal time for full expiration is……
4 seconds or less
What measures lung health in chronic conditions such as asthma
spirometer
The number of seconds it takes for the person to exhale from total lung capacity to residual volume
Forced expiratory time
What is the normal outcome of FEV1/FVC ratio?
75% or grater (no obstruction of airflow is present)
Noninvasive method to assess arterial oxygen saturation
pulse oximeter
Is used as an outcome measure for people in pulmonary rehab because it mirrors conditions that are used in everyday life. Measures functional status in aging adults.
6 minute walk test
FEV1/FCF ratio of 60-70% is
mild obstruction

9(18)
What lung areas are we to listen to when doing an examination?
posterior from the apices at C7 to the base are T10 and laterally from the axilla down to the 7th or 8th rib

What disease starts with a small crust on the nipple apex and spreads to areola?
Paget disease
What factor do we need to consider when doing breast exams?
Age
What type of tissue composes most of the breast?
adipose tissue
Contains 15-20 lobes radiating from the nipple, and these are composed of lobules. Within each lobule are clusters of alveoli that produce milk
Glandular tissue
What are the reservoirs for storing milk in the breast?
ampullae or lactiferous sinuses
Fibrous connective tissue extending vertically from the skin surface to attach on chest wall muscles. These support the breast tissue
suspensory ligaments or Cooper ligaments
The relative proportion of glandular, fibrous and fatty tissues varies depending on….
age, cycle, pregnancy, lactation, and general nutritional state
After menopause, what 2 hormones decrease causing tissue to atrophy?
Estrogen and Progesterone
What is this dead tissue replaced with?
fibrous connective tissue
Drooping of the breast in aging adults is accentuated by….
kyphosis in some older women
On the breast, a shallow dimple is also called______
skin teather
