axillary temp
under armpit
0.5C < oral**
rectal temp
anus
0.5 > oral**
tympanic temp
forehead
oral temp
preferred, under the tongue
pulse assessment considerations
rate
rhythm
elasticity
force
temp normal
35.8-37.3
bp normal
120/80 mmHg
heart rate normal
60-100 bpm
resp rate
12-20 rpm
systolic pressure
top #
pressure against artery during contraction
diastolic pressure
bottom #
pressure at rest when heart recoils btwn contractions
Relaxation of heart
considerations for resp rate
rate, rhythm, depth
atrioventricular
tricuspid (RA=>RV) and mitral (LA=LV)
semilunar
pulmonic (RV=>aorta=>lungs) and aortic (LV=>systemic circulation)
route of blood flow
Inferior/superior vena cava => RA => tricuspid => RV => pulmonic => pulmonary artery => lungs => pulmonary vein => LA => mitral valve => LV => aortic valve => aorta => body
s3
soft, dull, low-pitched sound heard after S2 (Al-Ber-Ta)
norm in children and young adults, not normal in older adults
s1
AV valve closure (LUB-dub); represents start of systole
s2
SL valve closure (lub-DUB); represent end of systole
split s2
aortic valve closes b4 pulmonic (lub-T-DUB) on expiration
s4
very soft, low-pitched sound heart b4 s1 (NEW-Bruns-Wick)
usually abnormal
summation gallop
hearing s4-s1-s2-s3
murmurs
blowing, swooshing sounds arising from turbulent blood flow
arteries
high pressure vessels that deliver oxygenated blood
veins
low pressure, one-way vessels with valves that bring deoxygenated blood back to heart; closer to surface of skin
