NUR 145 Module C- Perfusion Test
Questions and Correct Answers
Sinoatrial (SA) node ✅pacemaker of the heart

Atrioventricular (AV) node ✅the secondary pacemaker of the heart

Depolarization ✅electrical activation of a cell caused by the influx of sodium into the
cell while potassium exits the cell

Repolarization ✅return of the cell to resting state, caused by reentry of potassium into
the cell while sodium exits the cell.

Refractory periods ✅1) effective (absolute) refractory period: the cell is completely
unresposive to any electrical stimulus; it is incapable of initiating an early depolarization
2) relative refractory period: if an electrical stimulus is stronger than normal, the cell may
depolarize prematurely

Cardiac cycle ✅-the events that occur in the heart from the beginning of one heartbeat
to the next
-the number of cardiac cycles completed in a minute depends on the heart rate
-each cycle has 3 major sequential events:
--diastole
--atrial systole
--ventricular systole

Diastole ✅period of relaxation of the heart.

Systole ✅period of ventricular contraction resulting in ejection of blood from the
ventricles into the pulmonary artery and aorta

Control of HR ✅Autonomic nervous system, baroreceptors

Cardiac output (CO) ✅total amount of blood ejected by one of the ventricles in liters
per minute

CO=svxhr

Stroke volume (SV) ✅amount of blood ejected from one of the ventricles per heartbeat

Preload ✅the degree of stretch (volume) of the ventricular cardiac muscle fiber at the
end of diastole

, Afterload ✅resistance to ejection of blood volume from the ventricle

Contractility ✅-force generated by the contracting myocardium
-ability of cardiac muscle to shorten

Ejection fraction ✅percentage of the end-diastolic blood volume ejected from the
ventricle with each heartbeat

Assessment of cardiovascular system ✅-Health history
-Demographic information
-Family/genetic history
-Cultural/social factors
-Risk factors
--Modifiable
--Nonmodifiable

Health history ✅-symptoms
-past health, family history
-medications
-nutrition

-pain or discomfort in other areas of upper body
-dyspnea
-peripheral edema, weight gain, abnormal distention due to enlarged spleen and liver
ascites
-palpitations
-unusual fatigue
- dizziness, syncope, or changes in LOC

Physical assessment ✅-general appearance
-assessment of the skin and extremities
-BP (pulse pressure, BP changes)
-arterial pulses
-jugular vein pulsations
-heart inspection and palpation
-heart auscltation
