Question 1: Moderate Variability ranges (most common)

Answer:

ranges from 6-25 bpm

Question 2: Causes of prolonged deceleration/hypotension

Answer:

due to epidural or spinal, vagal stimulation(vaginal exam) with SVE or pushing, valsalva maneuver (holding breath while pushing)

Question 3: Causes of prolonged deceleration/changes in environment

Answer:

abruption, uterine rupture, hypertonous uterus, cord accidents, maternal seizures, maternal death Question 4: Decreased variability that is not associated with drugs, sleep, or prematurity should be considered....

Answer:

an ominous sign

Question 5: Intensity of contractions

Answer:

strength of the contraction at its highest point

Question 6: avoid placing the internal spiral electrode on

Answer:

the fontanels or the face

Question 7: Variable decelerations

Answer:

caused by cord compression, decreased blood flow to the fetus and slowing of fetal heart rate - v-shaped

Question 8: Terminal Bradycardia

Answer:

late hypoxia- deficiency of o2 reaching the tissue of the mom and therefore fetus, cord prolapse, abruptio placenta, uterine rupture

Question 9: Minimal Variability ranges

Answer:

ranges less than or equal to 5 bpm

Question 10: moderate or marked variability is...

Answer:

good sign that the fetus is not suffering cerebral asphyxia

Question 11: Sinusoidal Pattern & causes

Answer:

waveform evenly distributed on STV or accelerations or decelerations; bleed from mom from MVA or RH+/- crossover, fetal hypoxia from fetal anemia

Question 12: Reassuring EFM tracing

Answer:

FHR 110-160, short term variability prsent, long term variability moderate or marked with accelerations, early decelerations may be present, no late decelerations, if variable not deep and repetitive

Question 13: Absent Variability ranges

Answer:

undetectable

Question 14: Variable deceleration

Answer:

doesn't have to be r/t contraction, shape variable has sharp drop and returns (v,u,w), onset is variable and abrupt, lowest point is variable, FHR not usually within normal limits (<110), cause umbilical cord compression, requires nsg action

Question 15: Early Decelerations

Answer:

consistent and uniform, mirrors contraction inversely, onset just prior to or early in contraction, lowerst point at or before mid contraction, FHR stays 110-160, cause head compression which decreases cerebral bld flow/vagal cont to monitor/chart

Question 16: When is variability decreased

Answer:

during periods of fetal sleep, after administration of certain drugs(pain, mag sulf,antihistimines), fetal tachycardia, fetuses less than 28 weeks gestation Question 17: For external monitoring what is the best placement of the transducer

Answer:

when placed over the fetal back

Question 18: Tachycardia sustained, causes

Answer:

FHR > 160 for >10 min, hypoxia, maternal fever or dehydration, drugs that stimulate beta receptors (terbutaline or cocaine), maternal hyperthyroidism, fetal anemia/prematurity

Question 19: Early Decelerations - causes

Answer:

caused by fetal head compression - vagal response

Question 20: long term variability is recorded as

Answer:

absent, minimal, moderate, and marked

Question 21: resting tone of uterus

Answer:

is when the uterus is at rest

Question 22: Method of assessment stimulation of fetus

Answer:

scalp (SVE), vibroacoustic stimulation; should see FHR accelerate in response

Question 23: baseline FHR; average, normal, don't count

Answer:

avg is observed in 10 minute period, normal 110-160, accelerations & decelerations; look at pattern over time

Question 24: Frequency of contractions

Answer:

measured in minutes, time between the beginning of one contraction to the beginning of the next

Question 25: Short Term variability

Answer:

"grass" beat to beat changes, can only be measure with internal monitor

Question 26: late deceleration nursing actions

Answer:

turn to left side, o2 mask 7-10 liters, discontinue pitocin, increase IV fluids/give bolus, continue to monitor FHR/vaginal exam to check progress of labor, notify MD/CNM

Question 27: Interpretation; start with, then,

Answer:

contraction pattern, frequency, duration and intensity; uterine resting tone; baseline FHR; variability; periodic changes (contraction)
