Heart and Lung Sounds_Check Off Flashcards
Identify the abnormal sound: pt. says E, ausculate A
Egophony
Heart sound: start of systole, AV valves close
S1, lub (low pitched)
How many areas are ausculated on the anterior, posterior, and lateral lung?
Anterior: 10 spots (5 each side)
Posterior: 12 spots (6 each side)
Laterally: 4 spots
** look at diagram
Describe the pitch and intensity of vesicular and bronchial breath sounds
Vesicular: low pitch, soft intensity
Bronchial: high ptich, loud intensity
Identify the abnormal sound: pt. says 99, you hear clear 99
Bronchophony
Location: aortic valve
R 2nd intercostal space
Location: Tricuspid/Right AV valve
L 4th intercostal space
List the order of timing of S1, S2, and carotid pulse
S1, pulse, S2
How many lobes does the left lung have? How many fissures?
2 lobes (superior, inferior)
1 fissure (oblique)
Heart sound: at atrial contraction (atrial kick), due to accelerated rush of blood in the ventricles
S4
Name the breath sound: long on inhalation, short on expiration
Vesicular (over lung fields)
Name the following breath sound: heard over entire lung, except beneath manubrium and interscapular region
Vesicular (over lung fields)
What causes S1?
Closure of AV valves; ventricular pressure > atrial pressure
Identify the abnormal sound: fine, noncontinuous rattling, high pitched, sound like rice crispies, heard on inhale (sometimes exhale), due to fluid in alveoli/bronchioles
Rales or Crackles
Why does the left lung have less lobes than the right?
Due to the space taken up by the heart on the left
Name the following breath sound: result from consolidation/compression of pulmonary tissue that assists in transmission of sound from the bronchial tree
Bronchial (tubular, over trachea)
Heart sound: end of systole, aortic/pulmonic valves close
S2, dub (loud)
Identify the abnormal sound: you ausculate clear whisper
Whispering pectoriloquy
T/F: S3 and S4 are normal heart sounds.
False: abnormal, seen with heart failure
Name the following breath sound: short on inspiration, long on expiration
Bronchial (tubular, over trachea)
** or equal on inspiration/expiration
Location: Mitral/Bicuspid/Left AV valve
L 5th intercostal space
Location: pulmonic valve
L 2nd intercostal space
Which breath sounds are louder?
Bronchial
Identify the abnormal sound: muscial sounds like high pitched clarinet notes, produced on inhale, due to constriction/obstruction
Wheeze
How many lobes does the right lung have? How many fissures?
3 lobes (superior, middle, inferior)
2 fissures (horizontal and oblique)
What instructions should you give your pt. prior to auscultation?
- sit up
- lean forward
- deep breaths
- turn your head away from me
Identify the abnormal sound: coarse rattling on exhale, very clear, low pitched, due to mucus in bronchi
Rhonchi
What causes S2?
closure of aortic/pulmonic valves; due to vessel pressure > ventricular pressure
Identify the abnormal sound: stratchy sounds produced by movement of pleural surfaces; “walking on fresh snow”
Pleural friction rub
Heart sound: as ventricles fill, due to vibration on ventricular wall
S3
