Questions with Correct Verified Solutions
What are the 5 P's of the labor process that can impact the labor experience?
passageway, passenger, powers, position of mother, & physiological response
What is an example of the Passageway in the labor process?
the maternal pelvis
What is an example of the Passenger in the labor process?
the fetus
What is an example of the Powers in the labor process?
contractions
What are examples of the Physiological response in the labor process?
preparedness, anticipation, and anxiety associated with labor
The ability to have a vaginal birth is the integral relationship between what 5 things?
mom's pelvis, shape of the pelvis, size of baby, contractions, & work of contractions
What hormone does the placenta produce that is associated with the pelvis?
Relaxin
What is the job of relaxin in relation to the placenta?
has a relaxing effect on the pelvis so it is better able to accommodate the babies head as the baby
descends into the pelvis
,What is the pelvic inlet formed by?
upper margins of the pubic bone and upper margins of the sacrum
What is the midpelvis formed by?
posterior part of the symphysis pubis, ischium, sacrum, and coccyx
What is the pelvic outlet bound by?
pubic arch anteriorly, ischial tuberosities laterally, and the tip of the coccyx posteriorly
What is the most common fracture of the baby during labor?
clavicle
Why is the clavicle x the most common fracture of the baby during labor?
the baby is coming through the vaginal wall and the shoulder can get stuck during labor
What is the most desirable position for the baby to be in during labor?
head down
What are sutures in the babies head? What do they allow for?
membraneous spaces that allow for molding
What are fontanels and what do they allow for?
membrane filled sacs that allow the brain to grow from a baby to a newborn
During labor, what do the sutures in a babies head allow for?
the skull bone to accommodate the mothers pelvis
,What fontanel is the first one to close in a baby?
posterior
What shape is the posterior fontanel?
triangular shaped
What fontanel is smaller? Which one is larger?
posterior; anterior
What shape is the anterior fontanel?
diamond shaped
If the baby is in occiput posterior (OP) position, what would the examiner feel?
posterior fontanel felt toward moms bottom laying on the bed
In what direction is the baby looking in occiput posterior positioning?
baby is looking up at the ceiling
For a baby to have the most effective labor and be able to get delivered in the most non-
traumatic way, how must the baby present?
its smallest package to moms perinatal floor
What does the babies smallest package require regarding positioning?
head/chin to be flexed down onto the chest which will present the smallest anterior/posterior
diameter
, If a baby is lying in OP position meaning his head is looking up at the ceiling, then is he
presenting himself into his smallest package?
no as he is not able to get into flexed position
What is the safest way to deliver a baby in terms of positioning?
occiput anterior
What is the occiput anterior position?
baby's head is down and facing the mothers front instead of her back
What way is the baby looking at the time of delivery in occiput anterior?
baby has his chin on his chest and is looking downward
How does occiput posterior positioning affect the labor?
labor will last longer and will not be as efficient
When a baby is in OP position, what do moms complain of?
back pain
Why do mom's complain of back pain when the baby is in OP position?
the baby's back/spine is rubbing against the mom's vertebrae
What is the biparietal diameter?
widest part of the head entering the pelvic inlet
What is the suboccipitobregmatic diameter?
baby presents his smallest anterior/posterior diameter fetal skull to mom's perinatal floor
