Q

asthma exacerbation starts by being a problem of:

  1. getting air in
  2. getting air out
A
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

Q

which is a better test in asthma exacerbation: FEV1 or peak flow?

A

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

Q

chest radiographs are rarely ordered for an asthma exacerbation. what would be the clinical situation in which this might be useful for the PCP?

A

r/o underlying pneumonia (e.g., presents with fever and copious productive sputum)

Q

the BP in secondary vs. primary HTN is typically higher

A

secondary HTN is markedly higher than primary

17
Q

second most common heart chamber hypertrophy

A

left atrial hypertrophy

18
Q

describe mitral regurgitation

A

in mitral regurgitation, incompetent mitral valves fail to close properly, allowing blood to regurgitate back up into the left atrium during systole. the end result is decreased CO potential. classic symptoms of low CO include dyspnea on exertion, orthopnea, chest pain, syncope, or pre-syncope. on physical exam, expect to hear a holosystolic murmur with a blowing quality grade 2-3/6 with radiation to the axilla.

19
Q

common cardiac comorbidity causing mitral regurgitation

A

LVH

Q

VALGUS stress indicates….

A

force being applied AWAY from midline

The valgus stress test is used to evaluate ligament damage. For the valgus stress test at 30 degrees, the examiner places one hand over the medial joint line while the other hand holds the foot/ankle. Valgus stress force is then applied laterally (away from the patient’s body) to the joint through the foot, while the fingers palpate for an increase in joint line opening.

Q

VARUS stress indicates….

A

force being applied towards MIDLINE
