Clin Med exam 2 Questions With Complete Solutions
Acute problems due to Atherosclerosis and MI Correct Answer
- Catecholamine-triggered arrhythmias
- Rupture of athermatous plaques by mechanical stress
- Increased blood coagulability in exercise stress
more common during strenuous exercise than at rest.
Afterload has a direct relationship with SV
true or false? Correct Answer False!
It's indirect.
Increased afterload indicates decreased stroke volume.
Describe LV blood flow Correct Answer -low during systole
-high during diastole
Opposite of RV blood flow.
Describe RV blood flow Correct Answer -high during systole
-low during diastole
opposite of LV blood flow
distension Correct Answer increased transmural pressure
gradient increases radius of vessels.
, EDV Correct Answer blood collected in ventricles during
diastole.
ejection fraction Correct Answer EF=SV/EDV
equation for lung compliance? Correct Answer TV/(Ppl
before inspiration-Ppl after inspiration)
ESV Correct Answer amount of blood remaining in a
ventricle after contraction.
formula for net filtration pressure Correct Answer Fluid
movement=(capillary hydrostatic pressure-interstitial fluid
hydrostatic pressure)-(plasma oncotic pressure-interstitial fluid
oncotic pressure)
how much blood does the heart use? Correct Answer 5% of
the body's blood supply.
hypercapnea Correct Answer excessive Co2 in the blood.
in a working heart afterload is determined by-? Correct Answer
-the pressure which must be exceeded for ejection to take place
-by the radius of the chamber is directly related to afterload.
in what clinical setting is anatomic dead space increased?
Correct Answer on a ventilator
intra plural pressure is always lower than intrapulmonary
pressure.
