Hesi Med Surg III Final Exam
1. what is the amount of blood pumped by the heart each minute✔✔ CO
2. all hemodynamic measurements are affected by what?✔✔ CO
3. what is normal cardiac output?✔✔ 4-8 L
4. what is a more accurate measurement of CO by taking BSA into
account?-
✔✔ cardiac index
5. what is normal cardiac index?✔✔ 2.4-4
6. what compensates for changes in CP by speeding up or slowing
down✔✔ -
heart rate
7. what is the amount of blood ejected by each heartbeat?✔✔ stroke
volume
8. what is the presure exerted on the ventricular walls by the volume of
blood filling the ventricle at the end of diastole?✔✔ preload
,9. if the preload is high, what do we see?✔✔ too much blood volume, fluid
overload HF
renal failure
10.if preload is low, what do we see?✔✔
dehydration from diuretic
11. what is the resistance to ventricular contraction to pump the blod out?-
✔✔ afterload
12.what is the pressure that the heart must overcome such as in MAP?✔✔
af- terload
13.if we have a high afterload, what do we see?✔✔ aortic
stenosis vasoconstriction
14.what is property of myocardial muscle fivers that allows them to
short- en✔✔ contractility
15.how do we measure CO?✔✔ HR x Stroke volume
16.what are minimally invasive lines for cardiac?✔✔ central venous
access arterial access
17.what are invasive lines for cardiac?✔✔ pulmonary artery catheter
(swan ganz)
, 18.where is the central line normally placed?✔✔ subclavian
vein jugular vein
19.why is central line good?✔✔ good way to give
meds give fluids
