B
30
The most common cause of an increase in pulmonary capillary pressure is: a. right ventricular failure b. left ventricular failure c. pulmonary edema d. pulmonary hypertension
B
31
High end ventricular diastolic volume means good or bad cardiac output?
Bad. Higher end diastolic volume means CHF which means CO or SV will be decreased
32
During exercises, you would expect a patient with heart failure to have a high or low stroke volume?
Low, and increased ventricular end diastolic volume will induce dyspnea and pulmonary edema.
33
Inotrophy is defined as:
contractility
34
Frank starling law of the heart is a relationship between ___ and ____
length and tension
35
Decreased stroke volume leads to hypertrophy which leads to increased ventricular mass which leads to increased atrial pressure
Just know this
36
Decreased stroke volume leads to increased ventricular end diastolic volume which leads to an increase in atrial pressure
Just know this
37
Increased levels of BNP and ANP(Natriuretics) are indicative of: a. heart failure b. acute coronrary syndrome c. heart disease d. all of the above
D. ANP and BNP are released by cardiac muscle during times of high filling pressure(detected by stretch receptors of atrium) and are used to diagnose and manage disease states(BNP is the most important)
38
True or false: Renal dysfunction can lead to CHF
True
39
Hepatomegaly occurs in this organ? It occurs when ____
Liver, increased fluid leads to hepatic venous congestion and decreased O2 perfusion
40
Name the 3 major "pneas" of CHF:
Dsypnea paroxymal nocturnal dsypnea orthopnea
41
Name 3 S/S of CHF:
``` Rapid respiratory rate rales/crackles with inspration S3 heart sounds peripheral edema jugular venous distention weight gain sinus tachycardia decreased exercises tolerance ```
42
In what population would a S3 heart sound be normal
Children
43
S1 is the ___ and S2 is the ___
lub, dub
