what would be an appropriate statement within the general survey
such and such is a 30 yom who is alert and oriented x 4. He has an erect posture and symmetrical bilaterally. Has a flowing even gait. Behavior is appropriate for the situation.
what is the thermostat of the human body
hypothalamus
influences on temp
diurnal cycle
menstrual cycle
exercise
age
diurnal cycle =
any pattern that recurs every 24 hours
Modified Allen's test =
test to see if the ulnar and radial arteries are sufficiently supplying the hand with blood
normal pulse range =
60 -100
stroke volume =
amount of blood pump with each contraction of the LV
normal pulse force =
2+
bounding pulse =
> 2 +
thready pulse =
< 2 +
things to assess about pulse =
rate
rhythm
force
normal ratio of pulse to resp rate
4:1
pulse pressure =
difference between systolic and diastolic
does heart want to fill faster or slower
slower. rapid pulse = decreased fill time
MAP =
(2D + S)/3
2 X diastolic + systolic / 3
average MAP is
60
MAP practically is
average pressure in the arteries to perfuse body tissues
some influences on BP
age
race
weight
emotions
sex
diurnal rhythm
stress
physiologic factors controlling the BP
cardiac output
peripheral vascular resistance
volume of circulating blood
viscosity of blood
elasticity of vessel walls
dilated vessels do what to peripheral vascular resistance
decreases it
cuff too small =
falsely high BP
too big cuff =
falsely low BP
3 important korotkoff sounds are
1 systolic pressure
4 muffling of sounds
5 diastolic pressure
what is a unique pressure difference in the thigh
thigh pressure higher in thigh than in the arm
coarctation of aorta =
narrowing of the aorta
what is normal BP
<120/<80
stage 1 hypertension =
140-159/90-99
stage 2 hypertension =
>160/>100
what are some special considerations in aging adults in regards to the general survey
