SUCCESS|NEWEST VERSION
Chest wall changes and aging - CORRECT ANSWER-anteroposterior diameter
increases, thorax becomes shorter, chest wall elasticity decreases, mobility of
chest wall decreases
interventions for chest wall changes with aging - CORRECT ANSWER-discuss
the normal changes of aging, discuss the need for increased rest periods during
exercise, pt may become anxious when working harder to breathe.
,Atelectasis - CORRECT ANSWER-Alveolar collapse
The top of the lung is called? - CORRECT ANSWER-Apex, extends above the
clavicle
What is the bottom of the lung called? - CORRECT ANSWER-Base, just above
the diaphram
Any problem with the right lung interferes with? - CORRECT ANSWER-Gas
exchange and perfusion.
When oxygen levels are high? - CORRECT ANSWER-hgb binds oxygen very
tightly and little oxygen is unloaded
when oxygen levels are low? - CORRECT ANSWER-hgb binds oxygen less tightly
and will rapidly and easily unload remaining oxygen to provide tissues with what
they need.
,Alveoli changes with aging? - CORRECT ANSWER-alveolar surface area
decreases, diffusion capacity decreases, ability to cough decreases, airways close
early
Interventions for alveoli changes with aging - CORRECT ANSWER-encourage pt
to turn, deep breathe, IS, encourage upright position
Lung changes with aging - CORRECT ANSWER-Residual volume decreases, vital
capacity decreases, efficiency of oxygen and Co2 exchange decreases, elasticity
decreases.
Interventions for lung changes with aging - CORRECT ANSWER-auscultation,
inspection, help pt maintain health and fitness, assess RR, encourage frequent
oral hygiene
Pharynx and larynx changes with aging - CORRECT ANSWER-muscles atrophy,
vocal cords become slack, laryngeal muscles lose elasticity and airways lose
cartilage.
interventions for pharynx and larynx changes with aging - CORRECT ANSWER-
have face to face conversations, pts voice may be soft and hard to understand
, Pulmonary vasculature changes with aging - CORRECT ANSWER-vascular
resistance to blood flow through pulmonary vascular sys increases, pulmonary
blood volume decreases, risk for hypoxia increases. assess LOC pt can become
confused during acute respir conds
Exercise tolerance and aging - CORRECT ANSWER-bodys response to hypoxia
and hypercarbia decreases. assess for hypoxia
Important aspects to assess in respiratory system hx - CORRECT ANSWER--
smoking hx
-childhood illnesses: asthma, pneumonia, hay fever, allergies, eczema, croup,
cystic fibrosis
-adult illnesses: Tb, HIV/AIDS, Dm, HTN, Heart disease, hospitalizations, surgeries,
sleep problems,
Patient Education with Smoking Cessation - CORRECT ANSWER--list reasons
you want to quit smoking
-set a date to stop smoking
-ask help from those around you
-remind self of why wanting to quit smoking
-avoid places that tempt you to smoke
