2nd written exam quick info Flashcards
Sensitivity
true positive rate
if patient tests positive, they have the disease
Specificity

if patient tests negative, they do not have the disease
Ruling Disease in and Out
SnNout

prone
normal pulse is between
60-100 bpm
do not measure with thumb
measure for 60 sec
tachycardia=
over 100
bradycardia=
less than 60
normal respirations are in between
12-20
rise and fall of chest for 1 min
tachypnea
greater than 20
bradypnea

Normal BP
120/80
Width of BP cuff should be
Length of bladder- should be
1/3 to 1/2 circumference of limb
at least 80% of the circumference
if cuff is too wide
you underestimate BP
if cuff is too tight
you have a BP that’s too high
