NSG320 Practice Test Questions solved 100%
Correct
hypertension (HTN)
elevated blood pressure persistently higher than
Stage 1 -- 130-139 or 80-89
Stage 2 > 140 or > 90
Ejection Fraction (EF)
percentage of blood volume in the ventricles at the end of diastole that is ejected during
systole; a measurement of contractility
Action Potential (AP)
buildup of electrical current in the neuron
arterial blood pressure
Measure of the pressure exerted by the blood as it flows through the arteries.
Cardiac Index
amount of blood pumped out of heart per minute per sq meter of body mass. normal ranges
btwn 2.5 to 4.2 L/min/meter2
Cardiac Output (CO)
Amount of blood pumped in 1 minute (~5 L)
cardiac reserve
difference between resting and maximal cardiac output
coronary angiography
, specialized type of angiography that helps diagnose stenosis or obstruction of the arteries that
supply blood to the heart muscle
Diastole
Relaxation of the heart
Diastolic Blood Pressure (DBP)
The pressure in the arteries during the relaxation phase (diastole) of the cardiac cycle;
indicative of total peripheral resistance.
Heaves
sustained lifts of the chest wall in the precordial area that can be seen or palpated.
Korotkoff sounds
series of sounds that correspond to changes in blood flow through an artery as pressure is
released
Mean Arterial Pressure (MAP)
pressure forcing blood into tissues, averaged over cardiac cycle
mumurs
sounds created by abnormal, turbulent flow of blood in the heart
Point of maximal impulse (PMI)
the point where the apex of the heart touches the anterior chest wall and heart movements are
most easily observed and palpated
Preload
volume of blood in ventricles at end of diastole
Pulse Pressure (PP)
difference between systolic and diastolic pressure
