|
|
|
|
Fetal bradycardia
|
<110 bpm
d/t contractions, meds, squished head, hypoxia |
|
|
|
Fetal tachycardia
|
>160 bpm
d/t fetal distress, maternal temp, meds, early stages of hypoxia |
|
|
|
Variable deceleration of FHR
|
Near top of contraction
d/t cord compression |
|
|
|
Early deceleration
|
At or before the top of contraction
d/t head compression reassuring |
|
|
|
Late decelration of FHR
|
After contraction
d/t utero-placental deficiency fetus lacks proper oxygen |
Give O2
Call Dr. Maternal position on L side, hydration, dc any meds that might effect FHR, VS (possible hypotension) Fetal blood sample. |
|
|
Prolonged decelration of FHR
|
longer than 2 minutes

reposition mother |
|
|

60-90 bpm 16-24 resp. 95% PO2 36.2-37.6 temp. |
|
|
|
FHR
|
120-160
110, sleeping 180, crying |
|
|
|
Epidural S&S
|
vasodilation
decreased BP maternal and fetal decreased FHR decreased mom's ability to push, making stage 2 longer. VS and sensation check q5m |
|
|
|
Pitocin
|
Check vitals, baby condition (gestation, NST, FHR 30min.), position, presenting part, engagement, bishops score.
Monitor, hyperstimulation of uterus (titonic contractions) Risks, uterine rupture, water intoxication, fetal hypoxia and fetal death. During check, maternal VS, contraction status, FHR, I&O Discontinue if: non-reassuring FHR, contractions <2min, duration >60 seconds |
|
|
|
Bishop's Score
|
Cervix's readyness for labor
|
|
|
|
Crowning
|
Fetal head is encircled by the external opening of the vagina.
Birth is inminent. |
|
|
|
Baseline of FHR
|
what heart rate is equal to after 10 min
# heart rate is centered around |
|
|
|
Variability of FHR
|
shows how baby is responding to environment
amount of “wiggle” in the line. |
|
|
|
Accelrations fo FHR
|
Baby movement
|
|
|
|
ROM nursing interventions
|
Immediately asses FHR and check for proplapse of umbilical cord.
|
|
|
|
Fetal risks of a prolapsed cord
|
decreased blood flow.
labor can increase compression. with no relief the fetus will die. |
|
|
|
Nursing care for a prolapsed cord
|
Mother is kept horizontal, w/O2. Knee chest position is also appropriate.
FHR. pressure on fetal head is necessary to relieve pressure on cord. |
|
|
|
assessments during latent phase
|
q30m: contractions
q1h: BP, respirations, FHR q4h: temp |
|
|
|

|
tablet inserted vagianally to induce labor. @risk for uterine rupture.
|
|
|
|
Administration of Pitocin for induction
|
should achieve contractions q2-3m lasting 40-60 seconds
Uterus should relax to full resting tone baseline between contractions. |
|

q30m: BP, pulse, resp, FHR |
|
|
|
assessments during active phase
