Nurs 122 Exam #2 UPDATED ACTUAL Questions and
CORRECT Answers
What happens as you age? diminished chest expansion
Changes in the chest
What happens as you age? become thinner & osteoporosis
Bones
What happens as you age? lose their shape
Alveoli
What happens as you age? Diminished cough reflex
Cough
What happens as you age? less sensitive to hypoxia and hypercapnia
Brain
Hypercapnia excessive carbon dioxide in blood
Common significant deviations of the chest for older -marked dorsal curvature
adults include
-kyphosis
-increased AP diameter of chest [barrel chest]
-diminished chest expansion
As we age, bones become -thinner
-more rigid
-change shape
-muscles may become weakened
As we age, bones become thinner, more rigid, change this results in lower oxygen level w less CO2 removed from body & decreased
shape and muscles may become weakened ability to cough
Osteoporosis causes decreased thoracic vertebrae height
Aging also causes the alveoli to lose shape causing SOB
, As we age, decreased sensitivity, large amounts of particles that are more difficult to
expectorate can collect in lungs
Due to diminished cough reflex with
Expectorate to spit
In addition, as we age less sensitive to hypoxia [low oxygen & hypercapnia [higher than normal CO2] &
higher residual volume
The brain
As we age, as a result, older persons are at increased risk for pneumonia and bronchitis
the brain is less sensitive to hypoxia [low oxygen &
hypercapnia [higher than normal CO2] & higher residual
volume
Lung two cone-shaped, elastic structure suspended within thoracic cavity
Lung are paired; not completely symmetric
Right lung 3 lobes [upper, middle, lower]
Left lung 2 lobes [upper and lower]
The apex of each lung extended slightly above clavicle
The base of each lung at level of diaphragm
