Miscellaneous Flashcards
most common stenotic heart valve
aortic (aortic stenosis)
most common heart chamber hypertrophy
LVH (left ventricular hypertrophy)
most common incompetent heart valve leading to regurgitation
mitral (mitral regurgitation)
priority sequelae of mitral regurgitation
decreased cardiac output s/t blood regurgitating backwards into the atria
dx: grade 2-3/6 holosystolic heart murmur with a “blowing” quality with radiation to the axilla
mitral regurgitation
(2) most common locations for a heart murmur to radiate to
- neck/carotids
2. axilla
characteristics of mitral regurgitation heart murmur
low grade 2-3/6
holosystolic
“blowing” in quality
radiates to the axilla
s/s of decreased CO
dyspnea on exertion
chest pain
orthopnea
syncope
where is the PMI usually located and why is it commonly displaced
5th intercostal space, mid-clavicular line
commonly displaced by LVH
asthma exacerbation starts by being a problem of:
- getting air in
- getting air out
2. getting air out problem of air trapping leads to prolonged exhale decreased FEV1 (exhale) is an early sign trouble getting air in (decreased SaO2) is a late sign
first clinical test to decrease in an asthma exacerbation: o2 sats or FEV1?
FEV1
which is a better test in asthma exacerbation: FEV1 or peak flow?
FEV1 (as part of spirometry)
you may see peak flow more commonly in practice because it is cheap, but for boards the FEV1 and spirometry is the more EBP answer
chest radiographs are rarely ordered for an asthma exacerbation. what would be the clinical situation in which this might be useful for the PCP?
r/o underlying pneumonia (e.g., presents with fever and copious productive sputum)
S3 heart sound typically indicates
systolic dysfunction, such as in heart failure
S4 heart sound typically indicates
diastolic dysfunction, typically as the result from longstanding HTN or repeated episodes of cardiac ischemia
