Chapter 17: Intrapartum Fetal Surveillance Flashcards
Adequate fetal oxygenation requires normal blood ______ and _________ to the placenta.
flow, volume
Adequate fetal oxygenation requires adequate exchange of ___________ and _______________ in the placenta
oxygen, carbon dioxide
Adequate fetal oxygenation requires normal oxygen ____________ in the blood
saturation
Adequate fetal oxygenation requires a(n) ______________________________________________ between the placenta and fetus through vessels in the umbilical cord
open circulatory path
Adequate fetal oxygenation requires normal fetal ____________ and ________________________ functions
circulatory, oxygen carrying
Gelatinous substance in the umbilical cord that helps cushion it
Wharton’s jelly
Actual decrease in maternal blood volume is caused by this
hemorrhage
Relative decrease in maternal blood volume is caused by this
altered distribution
Epidural block anesthesia and resulting hypotension is an example of (actual, relative) reduction in blood volume
relative
Term for contractions that are too long, are too frequent, or have an inadequate relaxation period
tachysystole
Contractions that are too long are more than _______________
90-120 seconds
Contractions that are too frequent are closer than every ___________
2 minutes
Contractions with an inadequate relaxation period are less than _____________
30 seconds
Term for separation of the placenta before birth
abruptio placentae
Term for necrosis of varying amounts of placental tissue
infarcts
Term for umbilical cord around the fetal neck
nuchal cord
Low fetal _____________, ___________, or __________ may cause fetal tissues to be hypoxic despite adequate oxygenation and exchange.
blood volume, hypotension, anemia
This fetal monitoring method allows increased mobility of the mother
Auscultation of FHR
This fetal monitoring method allows the mother to use water-based pain management
Auscultation of FHR
This fetal monitoring method provides a more natural atmosphere
Auscultation of FHR
This fetal monitoring method can only assess FHR and uterine activity for a small part of labor
Auscultation of FHR
This fetal monitoring method might have distracting interruptions
Auscultation of FHR
This fetal monitoring method may be uncomfortable due to pressure of the instrument
Auscultation of FHR
This fetal monitoring method is staff intensive and may require a nurse-to-staff ratio greater than 1:1
Auscultation of FHR
This fetal monitoring method is not recommended in high-risk conditions that require continuous fetal monitorin
Auscultation of FHR
This fetal monitoring method supplies more data than the other method
Electronic Fetal Monitoring (EFM)
This fetal monitoring method provides a permanent record
Electronic Fetal Monitoring (EFM)
This fetal monitoring method can show gradual trends in FHR and uterine activity
Electronic Fetal Monitoring (EFM)
This fetal monitoring method can be used continuously
Electronic Fetal Monitoring (EFM)
This fetal monitoring method allows the mother to listen to the sound of the fetal heartbeat, which can be comforting
Electronic Fetal Monitoring (EFM)
This fetal monitoring method can help anticipate beginning and end of contractions
Electronic Fetal Monitoring (EFM)
This fetal monitoring method allows one nurse to care for two patients during the first stage of labor
Electronic Fetal Monitoring (EFM)
This fetal monitoring method limits the mother’s mobility
Electronic Fetal Monitoring (EFM)
This fetal monitoring method may require constant readjustments from position changes or active fetus
Electronic Fetal Monitoring (EFM)
This fetal monitoring method requires readjustments as the fetus moves downward
Electronic Fetal Monitoring (EFM)
This fetal monitoring method’s belts/stockinette can be uncomfortable
Electronic Fetal Monitoring (EFM)
This fetal monitoring method is difficult to obtain good data with a thick abdominal pad
Electronic Fetal Monitoring (EFM)
______________ in FHR is the number one sign of fetal wellbeing.
Variability
This internal fetal monitoring method detects electrical signals from the fetal heart and involves a wire attached to fetal skin (often the head)
fetal scalp electrode (FSE)
This type of internal fetal monitoring senses intrauterine pressure and increases in intraabdominal pressure
Intrauterine Pressure Catheter (IUPC)
One type of IUPC has an additional lumen to infuse sterile solution (NS) into the uterus, which is used for this
amnioinfusion
FHR is termed bradycardia or tachycardia when it has been out of range for at least __________. If this occurs, check _____________.
10 minutes, temperature
To obtain an FHR baseline, obtain a clear tracing for ___________ while the uterus is at _______.
2 minutes, rest
This type of deceleration starts early in the contraction but returns to baseline at the end of the contraction
early
Early decelerations indicate this
head compression
Interventions required for early decelerations
none
This type of deceleration starts late in the contraction or towards the end of a contraction and continues after the contraction ends
late
Late decelerations indicate this
placental insufficiency
Late decelerations are expected with _______ BP and __________ patients
high, postterm
Interventions done for late decelerations
Change position (left side)
Stop Pitocin (oxytocin)
Increase rate of or bolus nonadditive fluids
Administer O2
Notify HCP
Type of deceleration that can occur anywhere
variable
Interventions for variable decelerations
Change position (left side)
Stop Pitocin (oxytocin)
Increase rate of or bolus nonadditive fluids
Administer O2
Notify HCP
Amnioinfusion
Term for infusion of sterile isotonic solution into the uterus, which can be used to increase the fluid around the fetus and cushion the cord and reduce likelihood of C section
amnioinfusion
