24
if you hear an S3 heart sound, which high pitched abnormal breath sound is most likely associated with CHF?
crackles there is congestion and fluid collection leading to crackles, will hear brief, discontinuous popping
25
what conditions is wheezing associated with?
COPD and asthma it's caused by airway obstruction
26
what abnormal respiratory sound is low pitched, rattling and resembles snoring?
Rhonchi ronquidos is spanish for snoring
27
what abnormal respiratory sound would you expect to hear with COPD, bronchiectasis, pneumonia, chronic bronchitis, or cystic fibrosis?
rhonchi
28
what abnormal respiratory sound would indicated pleural inflammation?
pleural rub auscultated in lower lateral chest area
29
what voice sound is an increased resonance with greater clarity and loudness of spoken words? example "99"
bronchophony clearer sounds are abnormal, indicated consolidation
30
what voice sound happens when "E" sounds change to a long, nasal sounding "A"
Egophony can be d/t lung consolidation/pneumonia
31
what voice sound is an increased loudness of whispering? You would recognize whispered words 1,2,3
whispered pectoriloquy
32
what is atelectasis?
lug collapse
33
what is emphysema?
trapping of air
34
what is pneumothorax?
compression of lungs d/t air build up, lungs can't fully expand

ROME
Respiratory Opposite Metabolic Equal
41
if pH is normal, is it uncompensated or compensated?
compensated
42
if PaCO2 is normal, is it metabolic or repiratory?
metabolic
43
if HCO3 is normal, is it metabolic or respiratory?
respiratory
44
if HCO3, PaCO2 and pH are all not normal, is it compensated, uncompensated, or partially compensated?
partially compensated
45
in COPD, is CO2 increased or decreased?
increased bc it can't get out oxygen is low, and pH is low
46
what is a later manifestation of cystic fibrosis?
anorexia
47
meconium ileus and acute bronchitis are early manifestations of what?
cystic fibrosis
48
during vigorous exercise, PO2 ________.
decreases acutely
49
name the pulmonary condition: acute episodes of airways narrowing and swelling, and may produce extra mucus, triggering coughing and a wheezing sound when you breath out.
asthma obstructive
50
name the pulmonary condition: obstructive condition in which inflammation and irritation of the bronchial tubes occurs, causing mucus build up. commonly caused by smoking
chronic bronchitis commonly caused by smoking
51
name the pulmonary condition: infection of one or both the lungs, alveoli fill with fluid or pus, making it difficult to breathe
pneumonia restrictive
52
name the pulmonary condition: abnormal permanent enlargement of air spaces distal to the terminal bronchioles, accompanied by the destruction of alveolar walls, leading to reduced gas exchange and progressive air trapping
emphysema
53
name the pulmonary condition: build up of excess fluid between the layers of the pleura outside the lungs
pleural effusion "water on the lungs" music studio example (thick walls)
54
name the pulmonary condition: collapsed lung where air leaks into the space between your lung and chest wall. there is still some air left in the lungs though
pneumothorax
55
name the pulmonary condition: complete or partial collapse of the entire lung or area of the lung, alveoli become deflated. commonly occurs after surgery.
atelectasis no air left
56
fremitus (vibration) will be louder when there is more or less air?
less
57
in pleural effusion, fremitus will be ____ and percussion will be ____
low, dull
58
percussion will be _______ when there is more air (big drum)
hyperresonant
59
when a lot of fluid is present, percussion will be ____
dull
60
when an adult (8+) collapses and there are two adults present, what should you do? what if you are alone?
one calls 911 and the other starts CPR if you are alone call 911 first the start CPR
61
order of actions for when an adult collapses?
check for responsiveness Compression Airway Breathing
62
if a child collapses and you are alone, what do you do?
start CPR, if no change after 2 min call 911
63
order of actions for when a child collapses?
check for responsiveness Airway Breathing Compression
