Q

pulmonary chest pain

Study These Flashcards
A

sharp knife like pain
SOB
activity intolerance

25
claudication
intermittent pain in legs after activity pain in leg after walking pain decreases with rest
26
fatigue
low energy levels assess for cause physical work, infection, disease
27
weakness
decreased muscular strength rarely psychological explore cause need more testing
28
dyspnea
difficulty lying flat at rest or exertion may be severe cardiac problem if at rest
29
coughing
assess if pulmonary or cardiac problem | is not if productive
30
thorax
mediastinum right pleural cavity left pleural cavity
31
primary muscles of inspiration
diaphragm | intercostal muscles
32
accessory muscles
all others
33
upper airway structures
nose pharynx larynx trachea
34
functions of upper airway
conduct air to lower airway | warm, filter and humidify air
35
structures of lower airway
trachea R/L stem bonchi bronchioles alveoli
36
external respirations
pressure gradient
37
internal respirations
cellular level
38
pons
regulates respiratory rhytm
39
medulla
controls respiratory rate and depth
40
abnormal lung sounds
crackles | wheezes
41
crackles
heard on inspiration and expiration could be cleared with coughing sounds like crackling or bubbling
42
cause of crackles
atelectasis | caused by emphysema
43
wheezing
heard on inspiration or expiration heard with asthma or pneumonia sounds like continuous music
44
diagnostic tests
sputum specimens pulmonary function tests pulse ox arterial blood gases
45
hypoxemia
blood oxygen levels below normal | tells how much O2 the lungs are delivering to the blood
46
normal O2
80-100
47
hypoxia
blood unable to take adequate amount of O2 to tissue
48
signs of hypoxia
agitation anxiety LOC headache bradycardia
49
