WITH CORRECT QUESTIONS AND
ANSWERS 2025
abnormally rapid heart rate - above 100 - CORRECT-ANSWERSTachycardia
abnormally slow heart rate - under 60 - CORRECT-ANSWERSBradycardia
volume of blood in ventricles at end of diastole - CORRECT-ANSWERSpreload
resistance against which left ventricle pushes blood out - CORRECT-
ANSWERSAfterload
contraction of heart .... provides increase in pressure to eject blood - CORRECT-
ANSWERSSystole
relaxation of heart.... required for filling chambers - CORRECT-ANSWERSDiastole
hypervolemia, regurgitation of cardiac valves, heart failure - CORRECT-
ANSWERSWhen is preload increased?
hypertension, vasoconstriction - CORRECT-ANSWERSWhen is afterload increased?
increase in cardiac workload - CORRECT-ANSWERSWhat increases when afterload
increases?
Volume of blood ejected by the heart in one minute:
cardiac output = heart rate x stroke volume - CORRECT-ANSWERSWhat is cardiac
output?
Volume of blood pumped out of ventricle- contraction - CORRECT-ANSWERSWhat is
stroke volume?
, closure of AV valves - CORRECT-ANSWERSThe heart sound, lubb is due to the
_________ .
closure of semilunar valves. - CORRECT-ANSWERSThe heart sound, dub is due to the
________.
heart rate 60-100 bpm. - CORRECT-ANSWERSpulse rate
dilates (opens) blood vessels, which allows blood to flow more easily
example: nitroglycerin - CORRECT-ANSWERSWhat do vasodilators do?
-decrease heart rate and blood pressure
-treat HTN & dysrhythmias
-reduce angina attacks - CORRECT-ANSWERSWhat do beta blockers do?
hardening of blood vessels - CORRECT-ANSWERSarteriosclerosis
plaque build up in the coronary artery causing clots, often leads to MI. - CORRECT-
ANSWERSAtherosclerosis
medications administered to increase urine secretion in order to remove excess sodium
and/or water.
- treats high blood pressure and congestive heart failure - CORRECT-
ANSWERSDiuretics
a drug that prevents clotting of the blood - CORRECT-ANSWERSanticoagulant
Transports cholesterol from liver to cells
Major factor contributing to atheroma formation - CORRECT-ANSWERSlow-density
lipoprotein (LDL)
Transports cholesterol away from the peripheral cells to liver—"good" lipoprotein
