Labor and Delivery Flashcards
Exam 1
Delivery Location Options
- Hospitals
- Home births
- Birthing centers
Where do most women choose to deliver?
Hospitals
Why do many women choose home births?
Many choose home births because of negative hospital experiences; Women may feel more comfortable, empowered, and in control at home.
Labor consists of five components, referred to as the five Ps: What are they?
Power
Passageway
Passenger
Psyche
Position
Five P’s of labor: Power
Refers to uterine contractions and pushing efforts
Five P’s of labor: Passageway
Refers to the anatomy of the patient’s bony pelvis and soft tissues
Five P’s of labor: Passenger
Refers to the fetus
Five P’s of labor: Psyche
Refers to the patient’s state of mind
Five P’s of labor: Position
Refers to patient position
Five Ps of Labor: POWER- what are the primary powers of labor
1 _ Primary powers of labor are the involuntary uterine contractions.
Five Ps of Labor: POWER- where do the primary powers of labor occur?
Primary powers occur in the upper two-thirds of the uterus and apply pressure to the fetus.
Primary powers occur in the upper two-thirds of the uterus and apply pressure to the fetus. What occurs as a response to the pressure?
In response to the pressure, the cervix dilates and effaces, allowing for passage of the fetus.
What effects power?
Contraction frequency, duration, and intensity affect power.
What can be administered to augment contraction power?
Oxytocin can be administered to augment contraction power.
Five Ps of Labor: POWER- what are the secondary powers of labor
2 _ Secondary powers are the voluntary action of pushing.
Secondary powers are the voluntary action of pushing- what does this mean?
Secondary powers are the maternal pushing efforts after the cervix is completely dilated.
What should occur with contractions?
Effective pushing should occur with the contractions and may require coaching from the nurse.
Which pelvis shape provides the most ideal passageway
Gynecoid pelvis shape provides the most ideal passageway.
What does passageway depend on?
The passageway also depends on the ability of soft tissue to stretch.
When would soft tissue be an issue for fetal passage?
Soft tissue is rarely an impediment to fetal passage but may be a problem if a woman has scar tissue from gynecologic surgery.
What helps to turn and orient the fetus through the cardinal movements of delivery?
The muscles of the pelvic floor help turn and orient the fetus through the cardinal movements of delivery.
Fetal station
The relationship between the fetal presenting part and the pelvis is assessed by fetal station.
A Zero Station
A zero station means the presenting part is at the level of the ischial spines.
Important factors related to the fetus and labor are:
Fetal head size, fetal presentation, fetal attitude, fetal lie, and fetal position.
Five Ps: Passenger: What is the largest part of the fetus?
The fetal head is the largest part of the fetus.
Five Ps: Passenger: What qualities of the fetal skull allow it to pass through the birth canal?
The fetal skull bones are not fused and allow for the head to adjust to the birth canal.
Fetal presentation
Fetal presentation - refers to the part of the fetus entering the pelvis first.
Fetal presentation: The majority of babies are in what position?
The majority of babies are in a headfirst or cephalic(vertex) presentation.
What is breech position?
A breech presentation means the baby is in a buttocks or feet first presentation.
Fetal attitude
Fetal attitude- refers to the position of the fetal parts in relationship to itself
( chin to chest best)
Fetal lie –
fetal position in relation to mother’s spine
