(VERSION A AND B) COMPLETE 250 QUESTIONS AND
CORRECT ANSWERS (VERIFIED ANSWERS) |ALREADY
GRADED A+
Uterine Stretch Theory - ANSWER: When maximum stretch, uterus gives up and
random partial contractions occur
Rhythmic contractions lead to delivery of baby
Oxytocin stimulation theory - ANSWER: Causes uterine contractions
Probably a factor but is not the entire thing for labor
Progesterone withdrawal theory - ANSWER: End of pregnancy, these levels will drop
off
If not adequte levels, will likely have a miscarraige`
Fetal cortisol and placental degeneration theory - ANSWER: If you give sheep high
levels of cortisol, they will go into labor
Fetal membrane phospholipid-arachadonic acid-prostaglandin theory - ANSWER:
Precursor hormones in placenta that get into moms blood stream and more
hormones increase
See higher levels of these in women who are in labor
Contractions - ANSWER: Firing and shortening of muscle fibers in the uterus
Muscle fibers of the uterus run up and down. When they relax, the lengthen.
Eventually they will get very short over time.
Muscle fibers also spiral around the uterus towards the middle and bottom. Donut
shaped muscle fibers around the cervix
Fundus will get smaller and smaller
Duration of contraction - ANSWER: How long the contraction lasts
Contractions will come in waves. Muscle fibers relax and it goes away for a bit.
Contractions appear as mountains when monitoring
Frequency of contractions - ANSWER: How often
, Measure from start of one contraction through contraction to the start of another
contraction
*Never exactly the same
Intensity of contraction - ANSWER: How strong the contraction is
Can put hands on mom's tummy and can feel the uterus bunch up
Rock hard belly means pretty strong contraction
Internal pressure catheter - ANSWER: Measure the amount of millimeters of
mercury of amniotic fluid is putting pressure on this
Not all moms are internally monitored. If concerned about strength of the
contractions, it could be good to use
Dilation - ANSWER: How open the cervix is
As the pressure of the baby gets stronger, cervix will dilate and become more and
more open
What does a closed cervix mean? - ANSWER: Not dilated at all (about the size of a
pencil
What is the maximum dilation? - ANSWER: 100 cm
Babies head will fit through about 10 cm
C-section, will make incision to be about 10 cm
Effacement - ANSWER: Thickness/length of the cervix, "how tall your donut is"
As labor progresses, less cervix btw baby and outside world
Normal cervix is about 1 inch, with labor the cervix will become thinner
Measure by percentages (not effaced at all =0%)
Fully effaced - ANSWER: Probably about the thickness of paper
100% effaced
Station - ANSWER: Where the head is in relationship to the ischial spines
Engaged, ballotable, crowning
