Question Answer
Tachycardia=? BPM; Bradycardia=? BPM
Show Answer

Hemorrhage and dehydration causes a decrease in?
Show Answer
Circulation blood volume and decreased SVR
Left or right heart failure? Blood backs up into the systemic circulation?
Show Answer
Right heart failure
Left or right heart failure? Blood backs up into the pulmonary circulation?
Show Answer
Left sided heart failure
What causes the first (S1) heart sound?
Show Answer
During ventricular diastole the atrioventricular (mitral and tricuspid) valves open and blood flows from the atria to the ventricles.
What causes the second (S2) heart sound?
Show Answer
During the systolic phase, the semilunar (aortic and pulmonic) valves open and blood flows from the ventricles to the aorta and pulmonary arteries.

Show Answer
12 hours.
Providers use ____ to diagnose acute myocardial infarcts.
Show Answer
Cardiac enzymes which are: Creatine kinase, cardiac troponins I&T

The amount of blood ejected from the left ventricle each minute it ____.
Show Answer
Cardiac output. Normal= 4 to 6 L/min
What is the formula for cardiac output?
Show Answer
CO= SV X HR
With respect to the conduction system of the heart, what does each control: ANS, PNS, SNS?
Show Answer
ANS= rate of impulsion generation and speed of transmission; PNS= originate from vagus, decreased rate and innervate atria, ventricles, SA and AV nodes; SNS= increased rate of impulse generation and speed, innervate all parts of atria and ventricles

Show Answer
Myoglobin; should be less than 90 mcg/L
What alterations in older adults result in decreased cardiac function?
Show Answer
Calcification of the conduction pathways, thicker and stiffer heart valves due to lipid accumulation and fibrosis, and decrease in number of pacemaker cells in the SA node
A ____ determines coronary blood flow changes with increased activity.
Show Answer
thallium stress test
____ is an invasive measure of intracardiac electrical pathways. It provides more specific information about difficult to treat dysrhythmias.
Show Answer
Electrophysiological study (EPS)
____ is a noninvasive measure of heart structure and heart wall motion. Demonstrates overall cardiac performance.
Show Answer
