advanced FHMHow do i maximize uterine blood flow? - ANSPosition change,hydration, decrease uterine
ctx(meds), reduce fear and anxiety
How do i maximize umbilical circulation? - ANSPosition change and amnioinfusion
How do i maximize oxygenation? - ANSPosition change, o2, maternal hydration, breathing
techniques, correct or treat underlying disease
BPP - ANSBiophysical profile
My job as a LD RN is to assess fetal oxygenation of laboring woman with the following: - ANS1.
Maximize uterine blood flow
2. Maximize umbilical circulation
3. Maximize oxygenation
How can oxygen delivery be interrupted? - ANSMaternal anemia, maternal decreases in cardiac
output, patient bleeding
Maternal anemia, decreases in mat cardiac output, and patient bleeding will diminish ______
________. - ANSOxygen delivery
Increased oxygen consumption occurs with ___________. - ANSHyperthermia
How do i decrease maternal oxygen consumption? - ANSBreathing techniques, pain
management, repositioning
Fetal oxygenation is dependent on the _____ _____ to the uterus and the placenta via the
___________ ______. It is also dependent on the? - ANSBlood flow via umbilical vein, integrity
of the placenta
Post date pregnancies results in ? - ANSDecreased fetal oxygenation bc of the SAo2 dropping
by 30% at 43weeks
The umbilical vein transport blood to the _____ and the umbilical arteries transport blood away
from the _____ and to the ________. - ANSVein to the fetus and arteries away from fetus to
placenta
Four fetal responses to decreased oxygen delivery? - ANSDecreased fetal movement,
decreased reactivity and decreased variability, ph goes down producing acidemia
, A base deficit of ____________ is of concern, any base excess of less than _____ indicates the
need for? - ANSA base deficit of greater than -6 is of concern, a base excess of less than -6
indicates need for fluids
Asphyxia - ANSAsphyxia is a Combo of hypoxia, acidemia, and metabolic acidosis
Normal cord gas PH - ANS7.20-7.29
Normal cord gas PCO2 - ANS49.2-56.3
Normal cord gas HCO3 - ANS22.0-24.1
Normal cord gas Po2 - ANS15.1-23.7
Normal cord gas BD - ANS2.7-8.3
Normal fetal oxygenation occurs with what criteria - ANSFhr 110-160, mod variability,
acceleration in presence of ut ctx, no decels with ut ctx,
What is the most consitent predictor of newborn acidemia? - ANSAbsent or min variability with
recurrent late or variable decels or bradycardia
What does a cat I and moderate variabilty indicate? - ANSA well oxygenated, meorologically
intact fetus which has reserves
Category I - ANSBL of 110-160, moderate var, no lates or variable decels, early decels or
accelerations may pr may not be present.
Bradycardia <110 is Category __ - ANSCat 2
Tachycardia >160 w/o variability is Category __ - ANSCat 2
Minimal or marked var is Category __ - ANSCat 2
Absent variability w/o recur decels is Category __ - ANSCat 2
Recurrent var decels w min or mod var - ANSCat 2
What constitutes recurrent - ANS50% or more w/ctx in 20 min
Absence of accels after stimulation - ANSCat 2
The two causes of variable decels are: - ANSFetal hypoxemia and cord compression
