NUR 729 NEONATES AND PEDS EXAM
QUESTIONS AND CORECT ANSWERS
Which age has highest rate of post op events?
birth to 12 months
How old is a neonate?
0-28 days
How old is infant? Toddler?
infant: 30 days - 1 year
toddler: 1-3 years
What is gestational age?
number of weeks and days measured from the first day of the LMP.
What is post-conceptual age (post menstrual)?
Gestational age + chronological age
-we care about this one more
What is corrected age?
,Age corrected for prematurity
Example: 4 months since birth but was 2 months premature, so corrected age= 2
months
24hr observation of infants <60 weeks post conceptual age due to ______
increased respiratory problems
Do Frank-Starling law apply to children?
-not really. They're already operating at the high end of the curve
True/False: more of the cardiac output in a neonate goes to the brain and heart
true
Peds have an immature myocardium and a _______ left ventricle. Increases in
afterload may cause a(n) ________ in CO
noncompliant
reduction
means if BP goes up, CO goes down in kids (really bad)
, Kids are ______ dependent for cardiac output
heart rate
Peds have a fixed ________
stroke volume
What receptor is underdeveloped in kids? What does this mean?
-baroreceptor reflex
-don't respond to hypotension with tachycardia like adults do
-parasympathetic innervation is dominant, not SNS
Epi or atropine for peds bradycardia. Why?
EPI
-peds maintain lower catecholamine stores and have blunted response to
exogenous catecholamines
SBP estimate easy equation
>1 year: age x2 +90 = SBP
HR and BP values for neonate, 12 months, 3 year, 12 year old
