Test 2: Heart & lungs Flashcards
hyperresonance of lungs can be heard in
asthma and COPD
soft and low pitched; inspiratory sounds that last longer than expiratory sounds without pause
vesicular breath sounds
inspiratory and expiratory sounds are about equal; heard often in the 1st and 2nd interspaces and b/t scapula
bronchovesicular breath sounds
loud expiratory sounds last longer than inspiratory sound with a short silence between.
bronchial breath sounds
discontinuous breath sounds
crackles or rales
continuous breath sounds
wheezes or rhonchi
discontinous, soft, high-pitched, and very brief breath sounds. Popping that sounds like wood in fireplace.
fine crackles
discontinuous, brief, popping breath sounds. Most common during inspiration.
coarse crackles
relatively high-pitched with hissing or shrill quality. mostly heard on expiration
wheezes
when “ee” sounds like “a” that suggest pneumonia
egophony
longer forced expiratory time is seen with
COPD
creaking or grating sounds that have been described as being similar to walking on fresh snow
pleural rub
continuous, low pitched sounds with a gurgling, snoring or rattle-like quality. More common during expiration.
rhonchi
an S3 gallop indicates
a change in ventricular compliance
mitral valve opens and rapid ventricular filling as blood flows early in diastole from atria into ventricle.
S3
S4 relates to a
stiff ventricle and atrial contraction
Stage I hypertension is
140-159/90-99mmHg
Stage II hypertension is
> 160/100
Prehypertension
129-139/80-89 mmHg
the carotid upstroke always occurs
in systole after S1
sounds or murmur coinciding with the carotid upstroke are
systolic
sounds or murmurs coinciding after the carotid upstroke are
diastolic
how to detect mitral stenosis
patient in left lateral decubitus and listen to apical pulse with bell of stethescope.
how to detect aortic murmurs
ask the patient to lean forward, exhale, and hold breath. listen with diaphragm from left sternal border to apex.
aortic regurgitation is heard at
2nd - 4th left interspaces
timing of aortic regurgitation
early diastolic
quality of aortic regurgitation
descrescendo, blowing, high pitched
aortic regurgitation can cause
left ventricular hypertrophy
heard in the right 2nd interspace that radiates to the carotids
aortic stenosis
timing of aortic stenosis
mid systolic murmur
quality of aortic stenosis
harsh sounding, crescendo-decrescendo heard higher at apex
aortic stenosis murmur is heard best when
patient is leaning forward
aortic stenosis is heard mostly in
elderly patients
tricuspid regurgitation is best heard over
lower left sternal border over xiphoid
timing of tricuspid regurgitation
holosystolic
quality of tricuspid regurgitation
blowing, increases intensity during inspiration,
tricuspid stenosis is best heard at
4th-5th ICS left of sternal border
timing of tricuspid stenosis
diastolic
quality of tricuspid stenosis
descrescendo, soft, and low-pitched
murmur usually associated with rheumatic fever
mitral and tricuspid stenosis
tricuspid stenosis increases in intensity by
exercise, inspiration, sitting forward
consider atbx prophylaxis prior to dentist appts for pateints with
tricuspid stenosis
group most associated with tricuspid stenosis
children, pregnancy
pulmonic valve regurgitation is heard best at
2nd ICS at left sternal border and radiates to apex
timing of pulmonic valve regurgitation
diastolic
quality of pulmonic valve regurgitation
High-pitched decrescendo murmur
most common causes of pulmonic valve regurgitation
pulmonary HTN or tetrology of fallot
pulmonic valve regurgitation is usually
asymptomatic
pulmonic valve stenosis is best heard at
2nd and 3rd left ICS
timing of pulmonic valve stenosis
midsystolic to late systolic
quality of pulmonic valve stenosis
harsh, crescendo-decrescendo
pulmonic valve stenosis usually found in
children-congenital
VSD is heard best at
4th left ICS
timing of VSD
holosystolic (throughout s1 and s2)
quality of VSD
harsh and loud with thrill
venous hum is due to the rush of blood from the _____ to the ____
jugular veins, superior vena cava
in venous hum, this is louder
diastole
location of venous hum
under the medial third of right clavicle
continuous murmur without a silent interval
venous hum
Described as a humming, roaring, low-pitched sound best heard with the bell.
venous hum
age group most affected by venous hum
children
innocent murmur caused by low-frequency vibrations generated by normal pulmonary valve leaflets during systole or periodic vibrations generated by a left ventricular false tendon.
stills murmur
stills murmur heard best at
2nd to 4th left ICS
timing of stills murmur
early and mid systolic
quality of stills murmur
musical
linked with a remarkably rapid ejection of blood from the left ventricle during systole
hypertrophic obstructive cardiomyopathy (HOCM)
HOCM best heard at
lower left sternal border
timing of HOCM
late systolic
Typically develops during a puberty growth spurt as an adolescent
HOCM
timing of coarctation of aorta
continous
congenital narrowing of aorta
coarctation of aorta
Patent ductus arteriosis is caused by
failure of closure of hole that connects pulmonary artery and aorta
assessment of PDA reveals
bounding pulses
timing of PDA
continuous
higher risk of PDA with
premature infants
grade of murmur that is loud with thrill
Grade 4
grade of murmur where it is audible without a stethoscope and thrill is palpable
grade 6
risk factors for PE
age > 60, pulmonary HTN, CHF, lung disease, stroke, cancer, trauma, DVT, oral contraceptives
s/s of PE
pleuritic chest pain, hemoptysis, dyspnea, pleural friction rub, fever
virchow’s triad with DVT
venous stasis, hypercoagulability, endothelial injury.
