The 4 P's of the birth process
The 2 powers of labor are?
- uterine contractions
- maternal pushing
cervical effacement is expressed as ?
percentage of its original length
the amount of cervical dilation is expressed in ?
The nurse should promptly report contraction duration longer than?
- 90 seconds or intervals shorter than 60 seconds and frequency closer than 2 minutes.
Why should the nurse report long lasting, short interval timed contractions?
- placenta doesnt get enough oxygen carrying blood, when the uterus is tightly contracted. (fetal oxygen supply)
2 reasons why the sutures and fontanelles of fetal head are important in the birthing process?
- allows for shaping, accomodation to size and shape of maternal pelvis.
- Provides landmarks to determine how the fetus is oriented within the mothers pelvis.
Right sacrum anterior- breech
Left mentum transverse- face presentation
Right occiput anterior-most common
Left occiout posterior- back labor
key difference between real and false labor
change in cervical effacemant/dilation
3 phases of 1st stage of labor
- Latent- 1-4 cm 4-6 hours
- Active- 4-7 cm and effacement 2-6 hours
- Transition- 7-10 cm complete effacement 2-6 hours
Typical maternal behaviours during 1st stage of labor
Latent- cooperative, alert, talkative, welcomes diversions, frequent urination, thirst.
Active- apprehensive, anxious, introverted, less social, focused on breathing, prespires, flushing, wants pain relief.
Transition- irritable, rejects support person, introverted, wants to give up, restless, leg tremors, fears losing control, want pain relief.
Typical maternal behaviours durng 2nd stage of labor
- Bulging perineum
- passage of stool
- spontaneoud pushing or urge
- states baby is coming
Third stage bmaternal behaviours
- increased energy
- curious about baby
- desires to nurse baby
- minimal pain with placental expulsion
Fourth thage maternal behaviours
- time for parents and new baby to get aquainted
- mother nurses baby
Nornal fetal heart rate
Characteristics of abnormal amniotic fluid
- cloudy yellow fluid-infection
- strong odor-infection
- meconium-possible meconium aspiration for baby
Assessments reportable to MD by nurse
- temp: 110.4>
- blood pressure: 140/90 > or <90 for systolic
- FHR: outside of 110-120/150-160
Baseline Fetal HR of 125 during labor is?
Normal for term fetus
When assessing duration of contraction by palpation, it is time by?
bef=ginning of one contraction, to the end of the same contraction
during normal labor, contraction usually become?
more frequent and longer duration
when the fetus is cephalic in presentation, the amniotic fluid is expected to be?
The thinning of the cervix during labor is called?
Fetal descent during labor is measured in relation to the mothers?
When the placenta is delivered with the fetal side presenting, its called?
A nurse should learn to evaluate the progress of labor by methods other than vaginal examination, primarily because vaginal examination increases?
risk of infection
whicj=h maternal position should be avoided during labor?
VBAC should be observed during labor, particularily for signs of ?
