DETAILED ANSWERS WITH RATIONALES (VERIFIED
ANSWERS) |ALREADY GRADED A+
normal fetal heart rate range - ANSWER: 110-160
what could it mean if FHR is high - ANSWER: infection, low o2, young
what could it mean if FHR is low - ANSWER: post date pregnancy
what is the number one way to know a babies age - ANSWER: sonogram
what do you do if theres low amniotic fluid, variable decels - ANSWER: amnioinfusion
if baby is stressed, the baby will divert the blood flow to the brain, heart, and
adrenals. this organ won't get good blood flow which will lead to what? - ANSWER:
kidneys, low urine output, low amniotic fluid
what category tracing is absent variability without decels - ANSWER: 2
what category tracing is absent variability with decels - ANSWER: 3
influences on fetal heart patterns that are outside the fetus - ANSWER: extrinsic
what type of influences are associated with maternal-fetal exchange:
-placenta
-maternal utero placental circulation
-fetal placental circulation
-placental transfer
-uterine blood flow
-umbilical cord
-amniotic fluid - ANSWER: extrinsic
ALL transfer takes place here - ANSWER: intervillous space
all babies have this with uterine contraction but it's worse with a problematic
placenta - ANSWER: transient hypoxemia
when is the only time you give an amnioinfusion - ANSWER: cord compression
influences on fetal heart rate that are inside the babies heart - ANSWER: intrinsic
where is the most oxygenated blood - ANSWER: ductus venosus, liver
, where does the blood go to avoid the lungs - ANSWER: foramen ovale
if the baby has this, then they DO NOT have metabolic acidosis - ANSWER: moderate
variability
what would cause a sympathetic response (things speed up, accelerations) -
ANSWER: infection, movement , loud noise, repositioning
what would cause parasympathetic response - ANSWER: variable decel, early decal,
post dates, head compression
what nerve decreases bp - ANSWER: vagus nerve
during this, the blood flow gets shunted to the brain heart and adrenals. can't
tolerate labor - ANSWER: hypoxemia
the degree of hypoxemia a fetus can tolerate before true tissue hypoxia and acidosis
occur - ANSWER: fetal reserve
3 things that indicate fetal well being - ANSWER: normal baseline, moderate
variability, no late or variable decels
signs of utero-placental insufficiency - ANSWER: late or variable decels
what is the first thing you should do with recurrent late decels - ANSWER: change
position
what should pH be - ANSWER: 7.10 or higher
what should CO2 be - ANSWER: 60 or lower
what should base excess or base deficit be - ANSWER: 12 or lower
if CO2 is greater than 60, what type of acidosis - ANSWER: respiratory
if base excess greater than 12, what type of acidosis - ANSWER: metabolic
the approximate mean FHR rounded to increments of ____ bpm during a ____
minute window, excluding:
-accelerations and deceleratons
-periods of marked variability - ANSWER: baseline fetal heart rate, 5, 10
for baseline fetal heart rate there must be at least ___ minutes of identifiable
baseline segments in a ___ minute window or the baseline for that period is
indeterminate - ANSWER: 2, 10
bradycardia is a baseline of < ____ bpm for > ___ minutes - ANSWER: 110, 10
