Q

hormones and menstruation

A
  • LH rises and causes follicles of ovary to produce estrogen
  • when estrogen levels increase, LH decreases
  • ovulation occurs after an LH surge damages the estrogen producing cells causing decline in estrogen
  • LH surge results in corpus luteum which produces estrogen and progesterone
  • estrogen and progesterone rises suppressing LH output
    lack of LH promotes degeneration of corpus luterum
  • cessation of the corpus luteum means a decline in estrogen and progesterone output
  • decline in hormones ends their negative effect on LH output
  • LH is release and menstrual cycle begins again

Q

function of the placenta

A
  • serves as interface between the mother and fetus
  • masking hormones to control the physiology of the mother to ensure fetus is supplied with nutrients and oxygen needed for growth
  • protecting the fetus from immune attack by the mother
  • removing waste products from fetus
  • inducing the mother to bring more food to the placenta
  • producing hormones that mature into fetal organs

Q

fetal circulation

A
  • blood from the placenta to and from the fetus back to the placenta
  • ductus venousus, ductus arteriosus, and formen ovale are the shunts during fetal life
  • placenta acts like lungs
  • arteries typically bring blood into the body but in fetal circulation, arteries are bringing blood to placenta and umbilical vein goes to the heart

Q

umbilical cord

A
  • formed from the amnion
  • lifeline from the mother to growing embryo
  • contains one large vein and two small arteries
  • wharton jelly surrounds the vein and arteries to prevent compression
  • at term, average umbilical cord is 22 in long and 1 in wide

Q

role of amniotic fluid

A
  • helps maintain a constant body temperature for the fetus
  • permits symmetric growth and development
  • cushions the fetus from trauma
  • allows the umbilical cord to be relatively free of compression
  • promotoes fetal movement to enhance MSK development

active labor

A
  • cervix has thinned out and opening up
  • baby’s head is facing mother’s side
  • effacement in active labor is 100%
  • contractions are 45-60sec/q2-5 minutes
  • moderate to palpation
  • 0.5cm-1cm/hr
  • progressive fetal descent
219
Q

recommendations from experts about pushing

A
  • labor down until she feels urge to push
  • follow spontaneous urges
  • directing a woman should be reserved
  • shouldn’t be directed to push longer than 8 seconds with each push
220
Q

how positioning can help push

A
  • push in upright position
  • increases pelvic diameter 28-30%
  • decreases duration of 2nd stage
  • decreased intensity of pain
  • decreased incidence of perineal trauma
221
Q

third stage of labor

A
  • expulsion of placenta
  • may be very happy or very tired
  • involved with how baby is doing; asking questions about baby’s well being
  • slowing of contractions
  • shrinking of uterus to grapefruit size; found at level of umbilicus
222
Q

fetal adaptation to labor

A
  • FHR: accelerations and slight decels
  • fetal circulation: uterine contractions may decrease circulation: watch for cord compression
  • fetal lung fluid is cleared from passages as infant passes through birth canal during labor and birth. process of labor contributes to absorption of some of lung fluid
  • fetal O2 pressure decreases
  • arterial carbon dioxide increases
  • arterial pH decreases
  • bicarbonate levels decrease
  • fetal respiratory movements decrease during labor
223
Q

maternal adapations to labor

A
  • increase in CO
  • increase in systolic and diastolic BP during contractions; baseline in between
  • increase HR
  • increase WBC
  • increase RR and O2 consumption
  • proteinuria
  • perineal stretching
  • euphoria, amensida
  • stomach empyting slower, nausea
224
Q

fetal assessment during labor and birth

A
  • true labor contraction
  • false labor contractions
  • FHR patterns (baseline, variablity, periodic changes, assessment methods, fetal scalp sampling, pulse ox, stimualtio
225
Q

factors for proper oxygenation of fetus

A
  • normal maternal BF and volume to placenta
  • normal oxygen saturation in maternal blood
  • adequate exchange of O2 and CO2
  • open circulatory path between placenta and fetus through vessels in umbilical cord
  • if not maintained can lead to fetal hypoxia
226
Q

amniotic fluid allows for

A
  • proper bone growth
  • lungs to develop properly
  • prevents pressure on umbilical cord
  • keeps constant temperature
  • cushions fetus from sudden blows or movement
227
Q

characteristics of amniotic fluid

A
  • color: clear (if colored with green it means meconium indicating fetal distress)
  • odor: should be odorless (if foul smelling, may indicate infection)
  • amount: scant: gross scant: high leak: gross: forwaters
  • time: note time leak is first observed
