Intrapartum nursing Flashcards
What is acme?
The peak or most intense part of the uterine contraction.
What is the decrement?
Period after the acme that the contraction is waning.
What is the increment?
Period before the acme that the contraction is building.
What is effacement and how is it measured?
Thinning and shortening of the cervix. Shortens and thins as baby nears the cervix. Estimated at a percentage. 100% is fully effaced.
What is cervical dilation?
As the fetus nears the cervix, it is pulled apart and upward. This dilation is measured in cm and 10 is full dilation.
What is intensity of the contraction and how is it measured?
The strength of the contraction. Measure in:
Mild-uterus feels like tip of nose
Moderate-uterus feels like chin
Strong-uterus feels like forehead
What is the duration in contraction language?
Length of contraction from beginning to end. Start at beginning of increment to end of decrement. Usually measured in seconds.
What is the interval in contraction language?
Length from end of one contraction to the beginning of the next. This is when the exchange of fetal nutrients, waste, oxygen across the placenta take place.
When are mom’s vital signs best assessed during labor?
Between contractions (during the interval period)
What are the four factors of the birth process? (also called the 4 p’s)
Power (of contractions and pushing)
Passage-(how mom is built)
Passenger
Psyche
What is the first stage of labor?
Onset of labor to full dilation
What is the second stage of labor?
Full dilation through birth of baby
What are the two major fontanelles?
Anterior-Diamond shaped and formed by the two coronal, one sagittal and one frontal sutures
Posterior-Triangular and formed by 3 sutures (one sagittal and two lamboid) It is very small and feels more like a slight depression in skull.
What is the fetal lie?
How the baby is LYING in uterus (longitudinal or transverse or oblique)
What is the fetal attitude?
The relation of the baby’s body parts to each other (head, arms, legs flexed or extended)
What is the fetal presentation?
Which part is PRESENTING to outside world first-1. Head (cephalic) 2. breech 3. Shoulder
What is concern in breech births?
Umbilical cord gets in a bind and can be compressed while waiting on head to be delivered. Head delivery is rushed.
What is frequency in contraction language?
Period of time from start of one contraction to start of next contraction. This is what is commonly used to measure nearness of delivery.
What is fetal position?
Presentation in relation to maternal pelvis. Maternal pelvis divided into 4 quadrants -anterior, posterior, right, left. What part is presenting is oriented to position of mom’s pelvis. So occiput, mentum (chin) or sacrum can present in anterior, posterior, left, right quadrants.
What are cardinal movements of labor?
Natural changes of position of baby as it makes its descent through pelvis and out. See other slides for breakdown of position changes.
What is first and second cardinal movement of labor?
Descent-baby’s presenting part starts into true pelvis
Engagement-Head in pelvic cavity
What are 3rd and 4th cardinal movements of labor?
Flexion-Chin down
Internal rotation-head twists to fit through widest part of pelvis
What are 5th, 6th, 7th cardinal movements of labor?
Extension-chin up (this happens as baby is crowning and head delivers)
External rotation-Twist of head, shoulders to allow for shoulders to deliver
Expulsion-finish delivery
What is molding in labor language?
Head shape changes to fit through birth canal
What is supine hypotensive syndrome?
Mom lies flat-baby impedes blood flow-BP drop in mom
What is bloody show?
Warning sign of impending labor called a premonitory sign. Mix of thick, bloody mucus discharge shows cervical ripening
