NURS 352 EXAM QUESTIONS AND 100%CORRECT ANSWERS
Antepartum Fetal Surveillance-ANSWER fetal movement assessment, nonstress test,
contraction stress test, biophsycial profile, umbilical artery doppler velocimetry,
ultrasound, amniocentesis, chorionic villi sampling
Maternal conditions that require additional fetal surveillance-ANSWER antiphospholipid
syndrome, hyperthyroidism, hemoglobinopahties, cyanotic heart disease, lupus,
chronic renal disease, type 1 diabetes, hypertensive disorders,
pregnancy conditions that require additional fetal surveillance - ANS pregnancy
induced hypertension, decreased fetal movement, oligohydramnios, polyhydramnios,
intrauterine growth restriction, postterm pregnancy, isoimmunixation, fetal anomalies,
previous fetal demise, multiple gestation
fetal movement assessment - ANS kick counts, done after dinner with mother resting on
side with 10 movements in 2 hours and no smoking for 2 hours before counting
advantages of fetal movement assessment ANSWER low tech, can be done daily, done
on all pregnancies, reassuring for mother
intrapartum fetal assessment ANSWER electronic fetal monioring- external or internal
monitoring, intrauterine pressure catheter
components of EFM interpretation ANSWER baseline, variability, periodic changes
3 tier fetal heart rate interpreteation ANSWER 3 categories
,variation of FHR in EFM - ANSWER variation of FHR around baseline of 5-10 which
indivates parasympathetic system, chemoreceptors, baroreceptors and cardiac
responsiveness health
acceleration in EFM - ANSWER up 10-25 of baseline which indiates sympathetic system
what decreases variability - ANSWER prematurity-specifically before 28 weeks, hypoxia,
congenital heart anomalies, fetal tachycardia, fetal metabolic acidosis, CNS
depressants,, fetal sleep cycles,betamethasone, neurological abnormality
when should variability be present - ANSWER after 32 weeks
Absent variability-ANSWER amplitude range undetectable
minimal variability-ANSWER <5 bpm
moderate variability-ANSWER 6-25 bpm
Marked variability-ANSWER >25 bpm
most significant sign of fetal compromise-ANSWER Variability in FHR that is persistently
absent or minimal
normal range hr fetal-ANSWER 120-160
fetal bradcardia-ANSWER less than 120
causes of bradycardia in fetus-ANSWER heart block, occiput posterior, transverse
position, serious fetal compromise
,tachycardia in fetus - ANSWER > 160
mild tachycardia in fetus - ANSWER 160-180
severe tachycardia in fetus - ANSWER > 180
tachycardia > 200 bpm in fetus - ANSWER usually due to congenital anomaies or fetal
tachyarrhythmia
persisent tachycardia w fetal hypoxia, fetal anemia, maternal fever suggests - ANSWER
chorioamnionitis
category 1 - ANSWER Baseline 110-160, variability is moderate, accelerations present
or absent, early decelerations present or absent, and variable or late decelerations
absent
what does category 1 mean - ANSWER Not a risk to a fetus - normal acid-base status at
time, routine care
category 2 - ANSWER tachy or brady cardia w/o absent variability, minimial variability,
absent variability w/o recurrent decelerations, marked variability, absence of
accelerations after stim, recurrent variable decelerations with miniminal or mod
varaibility, prolonged decelation from 2-10 min, reccurent late decelerations w mod
variability, variable decelerations w slow return to baseline or overshoot
category 2 means - ANSWER indeterminate, not predictive of abnormal fetal acid base
status but requires continued monitoring
category 3 - ANSWER sinusoidal pattern or absent variabiilty w recurrent late
decelerations, recurrent variable decelerations, or bradycardia
what does category 3 mean - ANSWER abnormal fetal acid base status, efforts to
expedite can resolve underlying cause
deceleration classifications - ANSWER early, variable, late, prolonged
, early deceleration - ANSWER FHR decrease before contraction, mirror image of
contraction and EHR
late deceleration - ANSWER Slowing of the fetal heart rate after the beginning of a
uterine contraction and continuing after the contraction is over.
VEAL CHOP - ANSWER V- Variable C- Cord Comphression
E- Early Decels H- Head Compression
A- Accelerations O - OK
L-Late Decels P - Placenta insuff
types of decreased placental exchange - ANS excessive contractions, hypotension,
maternal hypoxemia, hypertension, diabetes IUGR, abruption
IUGR - ANS intrauterine growth restriction
late deceleration picture - ANS
early deceleration picture - ANS
variable deceleration picture - ANS
variable deceleration - ANS Periodic change in fetal heart rate due to compression of
umbilical cord; the decelerations vary in onset, frequency, and waveform.-usually V or
W shaped
severe variable deceleration with overshoot - ANSWER variability preserved and shows
good reserve
