Assessment of Fetal Well-Being/Fetal
Monitoring(Completely solved)
Types of fetal monitoring correct answers kick counts
NST
OCT/CST
BPP
FSE
IUPC
Kick counts correct answers used by mom to self assess fetal well being
during 3rd trimester lay on L side and count movements in 1hr
10+ = reassuring
<10 = wait 1hr and repeat test
if still <10, contact provider
T/F: kick counts is considered to be a part of medical protocol correct answers false
Non-stress test (NST) correct answers first step in assessment of fetal well-being
utilizes external doppler to continuously monitor fetal HR
used in prenatal assessment for high risk pregnancy
Oxytocin challenge test (OCT)/
Contraction stress test (CST) correct answers combines NST with external tocometer to allow for
eval of fetal HR in response to contractions
used during natural labor or prenatally with dilute infusion of oxytocin to stimulate contractions
What is an OCT/CST used for in the prenatal setting correct answers helps determine if a high-
risk pregnancy can continue or if the fetus should be delivered
Biophysical profile (BPP) correct answers US study done in addition to NST
evaluates amniotic fluid volume, fetal tone, fetal activity, and fetal breathing movements
What is the 5th category measured in BPP? correct answers NST
What is the scoring like for BPP? correct answers 8-10 is reassuring
total possible is 10
, Fetal scalp electrode (FSE) correct answers used during labor to measure timing and strength of
contractions
threaded into uterine cavity past presenting part of fetus and requires rupture of membranes
What units are used to measure uterine contractions? correct answers Montevideo units
Purpose of performing NST and CST correct answers to monitor fetal well-being to ensure a
positive outcome
Purpose of NST and CST in prenatal setting correct answers determine if a high-risk pregnancy
should be allowed to continue, if labor should be induced, or if a C-section should occur
Purpose of NST and CST in delivery setting correct answers determine if delivery should
continue vaginally, if a poor outcome is likely, or if a C-section is needed
Purpose of NST and CST in a trauma setting correct answers determine if the pregnant patient
can be safely discharged
When is NST and CST used? correct answers -prenatally w/ high risk such as SGA/IUGR, DM,
HTN
-Post-term pregnancies (start at 40-41wks q 3d)
-patients who report dec in fetal movement
-all patients admitted for delivery
-after maternal trauma
T/F: NST/CST is typically used at any given time during pregnancy correct answers false
typically not used before 32 weeks due to questionable reliability before this time
General explanation of NST/CST machine correct answers contraction transducer (toco) placed
on fundus
fetal heart transducer (doppler) placed on lower abdomen or wherever fetal heart tones are best
heard
remember to zero out at beginning
What information is charted on the top of the graph? bottom? correct answers Top: fetal heart
rate
Bottom: contractions
4 steps in evaluating results of NST/CST correct answers 1. determine fetal HR baseline
2. determine variability
3. determine if reactive pattern is present
