Maternity- Labor And Delivery Process Flashcards
Who does an intrapartum Nurse care for during each labor and delivery
The fetus mother and family unit
What are pre-monetary signs preceding labor
Back ache
weight loss
lightening
contractions
increase vaginal discharge or bloody show
energy burst
G.I. changes
Pre-monetary signs during labor of backache
Constant Low Dalbec a caused by pelvic muscle relaxation
How much weight should you lose during labor
0.5 to 1.5 kg weight loss
1-3 lbs
What is lightening
Fetal head descends to true pelvis about 14 days before labor
feeling like fetus has dropped
causes easier breathing
more pressure on bladder
more pronounced in first pregnancy
What are contractions
Irregular uterine contractions (Braxton Hicks) that eventually progress in strength and regularity
Premonitory signs of labor increase vaginal discharge or bloody show
Explosion of cervical mucus plug may occur
bloody tinged mucous plug from onset of dilation and effacement
What is an energy burst
Premonitory sign of labor
sometimes called nesting response
What G.I. changes can you have in the premonitory signs of labor
Nausea vomiting indigestion
less common
What is the first stage of labor consist of
The Latent stage
active phase
transition phase
What happens in the Latent stage of labor
Last 6 to 4 hours
cervical is dilated 0 to 3 cm
onset of contractions occur
mild to moderate irregular
occur 5 to 30 minutes and last 30 to 45 seconds
some dilation in effacement
woman is talkative and eager
What happens during the active phase of labor
3 to 2 hours
4 to 7 cm dilated
contractions more regular moderate strong
occur 3 to 5 minutes last 40 to 70 seconds rapid dilation in effacement
some fetal dissent
feeling helplessness with anxiety as contractions become stronger
What happens during the transition phase of labor
Last 20 to 40 minutes
dilated 8 to 10 cm
contractions very strong
occur 2 to 3 minutes less 45 to 90 seconds

What happens during the third stage of labor
Delivery of the placenta

What is Schultz’s Presentation
Shiny fetal surface of placenta emerges first
What is Duncan presentation
Dull maternal surface of placenta emerges first
What is the fourth stage of labor
Maternal stabilization of vital signs
Return to homeostasis
What is cervical ripening
Cervix become soft opens and partially effaced
can begin to dilate
What happens during the rupture of membranes
The water breaks can initiate labor or occur any time during labor
Common during transition phase
How long after the rupture of membranes do you go into labor
Within 24 hours after rupture
if greater than 24 hours fetus can lead to infection
What should the nurse do immediately after a rupture of membranes
Assess the FHR for abrupt decelerations
indicative of fetal distress to rule out umbilical cord prolapse

Head down
What is the fetal lie
The relationship of maternal spine to the fetus spine
What is a transverse lie
Fetus spine is horizontal informs a right angle to the maternal spine
will not accommodate vaginal birth require a cesarean it fetus does not rotate
What is a Parallel or longitudinal lie
Fetal spine is parallel to maternal spine either cephalic or breech presentation
Breech presentation can require what
A cesarean birth
What is the fetal attitude
Relationship of fetal body parts to one another

What does the third letter refrence in fetal position
The part of the maternal pelvis
anterior posterior or transverse
What is station
Measurement of fetal descent in CM with station 0 being the level of imaginary line of the ischial spine
What does a negative station mean
superior (above) to the ischial of spine
What does a postive station mean
Inferior (below) the ischial spine
What is the passageway of birth
The birth canal
size and shape must be adequate to allow the fetus to pass through
Cervix must dilate and efface in response to contractions
What is powers of birth
Uterine contractions which caused effacement and dilation
What is effacement
Shortening and thinning of the cervix
What is dilation
Enlargement or widening of the cervical opening and Canal
What is position of birth
Client should engage in frequent position changes during birth
whatever the maternal preference is
What helps aid in the fetal descent
Gravity
What is the physiological response of birth
Maternal stress tension and anxiety can produce physiological changes and impair progress of labor
What is a Leopold maneuver
Abdominal palpation of the fetal presenting part lie attitude descent and probable location where the fetal heart tones can be best auscultated
What is a Toko transducer
External electronic monitoring that is applied to the maternal abdomen over the fundus 
What does external electronic monitor
(Tocotransducer) 
Measures uterine activity
displays uterine contraction patterns
What is an external fetal monitor 
Transducer applied to the abdomen to assess FHR patterns during labor and birth
When do you obtain Group B streptococcus culture
Screen at 35 to 37 weeks
if results not available obtain culture at birth 
What does a postive Group B streptococcus culture mean
Start IV prophylactic antibiotic
What can a urinalysis in labor determine
Dehydration
ketonuria
proteinuria
glycosuria (implies gestational diabetes)
UTI (common in diabetes mellitus)
How often should you assess maternal vital signs
Check maternal temperature every two hours if membranes are ruptured
How do you assess uterine labor contractions
Placing a hand over the fundus to assess contraction frequency duration and intensity
What is frequency of a contraction
From the beginning of one contraction to the beginning of the next
What is duration of a contraction
Time between the beginning of a contraction to the end of the same contraction
What is intensity of a contraction
Strength of contraction at its peak described as mild moderate or strong
What is the resting tone of a uterine contraction
Tone of the uterine muscle in between contractions
What kind of contraction can reduce blood flow to the placenta resulting in fetal hypoxia and decreased FHR
 contraction duration (greater than 90 seconds ) or two frequent contractions (more than five and 10 minute periods) without suefficient time for uterine relaxation (less than 30 seconds)
What do you look for in a vaginal examination during labor
Cervical dilation and effacement
decent of fetus the birth canal
fetal position presenting part + lie membranes are intact or ruptured
What is the mechanism of labor in vertex presentation
The adaptations of the fetus makes as it progresses through the birth canal
What is engagement of labor
Occurs when the presenting part passes the pelvic inlet at the level of isheal spine station 0
What is the descent of labor
The process of the presenting part through the pelvis
What is flexion during labor
The fetal head meets resistance of the cervix pelvic wall
the head flexes bringing the chin close to the chest 
What is internal rotation of labor
The fetal occiput Ideally rotates to a lateral anterior position as it progresses from the ischeal spine to the lower pelvis
What is extension of labor
The fetus passes under the symphysis pubis where the head is deflected anteriorly and born
What is external rotation of labor
After the head is born it rotates to the position it occupied as it entered the pelvic inlet
What is birth by expulsion
After birth of head and shoulders the trunk of the neonate is born
What is the order that labor proceeds in
Engagement
descent
flexion
internal rotation
extension
external rotation
Birth by expulsion
How many times do we assess blood pressure and pulse after birth
Obtain blood pressure and pulse every 15 minutes after the first two hours of birth
When should be assessed temperature after birth
Temperature should be assessed every four hours for the first eight hours after birth and at least every eight hours
When should you assess the fundus in Lochia after birth
Every 15 minutes for the first hour
How can you prevent hemorrhage after birth
Massage the uterine fundus
Characteristics of true labor
Contractions begin irregularly but become Regular and frequent stronger less longer and are more frequent walking can increase contraction intensity progression in dilation in effacement
Characteristics of false labor
Painless irregular contractions decrease in frequency and intensity with walking stop with sleep or emptying bladder
no significant change in dilation or effacement
