OB Lab 1 Flashcards
When is baseline FHR observed
between contractions over 10 min
what is baseline FHR
110-160bpm
what interventions can a patient take for cramps after birth
tylenol/ibprofen
how long should pain last after birth
5-7 days
all pain should be evaluated for what
infection
what does a electronic fetal monitoring do
monitors fetal well being by monitoring fetal heart rate and contractions
what is fetal tachycardia and what could be the causes
over 160bpm
causes: hypoxemia, anemia, prematurity, maternal conditions, meds
what is accelerations FHR
increase in FHR 15bpm over 15 seconds - before 32 weeks 10bpm over 10 seconds
how is FHR and contractions monitored by internal fetal monitoring system
fetal monitoring- scalp spiral electrode, intrauterine pressure catheter measure contractions
what is effacement
thinning of the cervix
what is early deceleration FHR
symmetrical, gradual decrease in FHR with contraction - mirror
where should fundus level be one our postpartum
at umbillicus
what does late deceleration FHR look like
decel mirrors contraction but starts after contraction and ends after contraction
what is dilation
opening of cervix
what does BUBBLE -LE stand for in postpartum assessment
Breast, Uterine, Bladder, Bowels, Lochia, Episiotomy, Legs, Emotions
where is the uterus immediately postpartum
1/2 down between umbilical and symphysis pubic
how often should uterus be checked after birth
every 15 min for hour, then every 30min-nexthour then every 4 hours
what is involution
process of uterus returning to pre-pregnancy state takes about 6-7 weeks
how do you measure frequency of contractions
measure from beginning of one contractions to beginning of next contraction
what are braxton hicks
irregular cramping, doesnt cause cervical changes
what is the treatment for braxton hicks
position changes, hydration
what is lochia
vaginal discharge
1-3 days postpartum lochia =
lochia rubra (dark red)
4-10 days postpartum lochia =
lochia serosa (bright red)
10-28 days postpartum lochia=
lochia alba (yellow)
Intensity of contractions mild abdomen will feel like…
nose
Intensity of contractions moderate abdomen will feel like
chin
Intensity of contractions severe abdomen will feel like
forehead
how does a external fetal monitoring work
doppler ultrasound measures HR and tocodynanometer used to measure contractions
what is baseline variability
fluctuating in baseline FHR indicator of adequate fetal oxygenation during labor
what is minimal baseline variability
less then 5bpm
what is moderate baseline variability
best - 6-25bpm
what is marked baseline variability
over 25 bpm
what is fetal bradycardia and what could be some causes
less then 110bpm
causes: maternal position, decreased BP, cord compression
what is variable deceleration FHR
abrupt decrease in FHR 15 bpm by 15 seconds looks like a v or u
what is hyperstimulation
uterine tachysystole - excessively frequent contractions, over 5 within 1 minute of eachother over 10 min
what is deceleration FHR
decrease FHR below baselie
what is recurrent deceleration FHR
occurs 50% of contractions over 20 minutes
what is intermittent decelerations FHR
occurs less than 50% of contractions over 20 min
how much should the uterus decrease per day
1 fingerbreath (1cm)
when should the uterus not be palpable
10 weeks
what is prolonged decelerations FHR
decels over 15bpm below baseline over 2 min – immediate intervention needed
