S1_L5_Obj - 7-8 Flashcards
part of stethoscope: for low pitch sounds
bell
part of stethoscope: for high pitch sounds
diaphragm
t or f Listening to breath sounds through the pt gown or clothing is
the right way
f, Place bell/diaphragm directly against the chest wall
t or f Keep tubing free from contact from any objects
t, note: common error is tube rubbing against bed rails or other objects
t or f Eliminate noise from the environment while taking heart sounds
t, note: common error is auscultation in a noisy room
t or f do not wet the chest hair if thick
f, wet the chest hair bc chest hair can be interpreted as adventitious sound
t or f Ask pt to sit, if possible; or roll comatose pt to one side
t, common error is acceessing onlt convenient areas
HEART SOUNDS: found in what valves (5)
Aortic valve

Concentration of the 4 valves is found at _
erb’s point
t or f Apical pulse is similar to the location of the tricuspid valve
f, Apical pulse is similar to the location of the “mitral valve”

During _, splitting of S2 is audible
(physiologic split)
inspiration
splitting of s2 is called
physiologic split
abnormal heart sounds are also called
gallops
S3 also called as
ventricular gallop
S4 also called as _
atrial gallop
Faint, low-frequency heart sound
