NUFT EXAM 3 WITH COMPLETE SOLUTIONS
GRADED A+
QUESTIONS AND ANSWERS
primary role of arteries: ANSWER - carry blood away from the heart
primary role of veins: ANSWER - carry blood to the heart
______ contain oxygen rich blood ANSWER - arteries
what produces S1? ANSWER - closure of AV valves (mitral and tricuspid; *remember, they
close alphabetically! mitral before tricuspid)
what produces S2? ANSWER - closure of semilunar valves (aortic and pulmonic)
what heart "events" occur first? ANSWER - left side take place a split second before right
side
where is S1 heard best? ANSWER - apex (bottom of the heart; "point of maximal impulse")
where is S2 heard best? ANSWER - base (top of the heart)
what part of the stethoscope is used to ascultate murmurs? ANSWER - bell
4 characteristics of heart sounds: ANSWER - - frequency
- intensity
- duration
- timing
what heart sound occurs during systole? ANSWER - S1
, what heart sound occurs during diastole? ANSWER - S2
location of aortic and pulmonic ascultatory areas: ANSWER - 2nd intercostal space
location of erb's point: ANSWER - 3rd intercostal space
what ascultatory area are murmurs heard best? why? ANSWER - erb's point; valves come
closest to overlapping
location of tricuspid ascultatory area: ANSWER - 4th intercostal space
location of mitral ascultatory area: ANSWER - 5th intercostal space, mid-clavicle
what do extra heart sounds (S3 & S4) usually correspond with? ANSWER - misfiring of the
heart + heart failure
what disorders are murmurs generally related to? what is the sound caused by? ANSWER
- valve; thickness/speed of the blood flow
what is thyrotoxicosis? ANSWER - too much thyroid hormone circulating in blood stream
if a murmur correlates with a carotid sound, its a _____ murmur ANSWER - systolic
define stenosis: ANSWER - narrowing of a valve (narrowing causes turbulence)
what is a lift or heave? ANSWER - forceful cardiac contractions that cause a slight to
vigorous movement of sternum/ribs
how should a Pt. be positioned to inspect jugular veins? ANSWER - 45 degree angle
______ position can assist with palpating the apical pulse ANSWER - left lateral
assessing for edema: how long should the skin be depressed for? ANSWER - 5 seconds
