erythema
redness of skin
murmur
harsh, blowing sounds caused by disruption of blood flow
myocardial ischemia
oxygen needs heightened so heart has to work harder
systole
ventricular contraction, blood leaves the ventricles to go to the lungs or body.
what is the pacemaker of the heart
sinoatrial node (SA node)
how many times is the sinoatrial node set to discharge per minute
60-100
if the heart rate is initiated in the atrioventricular node, how fast would the heart beat per minute
60
if the heart rate is initiated in the bundle branches, how fast would the heart beat per minute
30
what is the term used to describe a sudden droop in blood pressure that may occur when an older client changes position from lying or sitting to standing
orthostatic hypotension
what two cultural groups are at the highest risk for hypertension
african americans, spanish (mexicans/cuban/filipino)
dullness when percussing over the heart is
an abnormal finding that could indicate an enlarged heart.
the third heart sound (S3) is heard
immediately after S2.
S3= kentucky
the fourth heart sound (S4) is heard
immediately before S1
S4= there are 4 e's in tenessee
what is happening when S1 is heard?
tricuspid and mitral (AV) valves are closing. begins systole
what is happening when S2 is heard?
aortic and pulmonic (semilunar) valves are closing. end of systole and beginning of diastole.
when would the nurse hear S3
when AV (tricuspid & mitral) valves open, blood flow into ventricles may vibrate during mid-diastole, termed ventricular gallop.
when would the nurse hear S4
before S1, termed atrial gallop.
what is the significance of S3
may indicate heart failure or fluid overload.
what is the significance of S4
may indicate hypertension or ventricular hypertrophy
at erb's point you can hear
S1 and S2 equally
at the aortic and pulmonic valves you can hear
S2
at the mitral valve you can hear
S1
