NM 704 Exam 3: Questions And Step-by-Step Answers
3rd stage of labor definition Right Ans - - period following birth of baby
through expulsion of placenta
3rd stage lasts Right Ans - - typically less than 10 min
retained placenta Right Ans - - more than 30 min from birth to placenta
expulsion
placental seperation Right Ans - - results of abrupt decrease in size of
uterine cavity during & following birth of neonate
- sudden disproportion btwn area of implantation & placental size --> cxes
plancenta to buckle & separate from decidua
placental expulsion Right Ans - - schultz --> occurs majority of time
- duncan
- both mechanisms considered normal
schultz Right Ans - - placenta separates centrally
- fetal side --> smooth & shining membrane --> exits vagina 1st
- membranes expelled last with maternal side of placenta inside amniotic sac
- inverts placenta & amniotic sac --> cxes membranes to peel off remainder of
decidua & trail behind placenta
placental separation Right Ans - - schultz --> fetal side
- duncan --> maternal side
schultz & bleeding Right Ans - - conceals majoring of bleeding until
placenta & membranes are expelled
duncan Right Ans - - separates marginally
- doesn't invert
- maternal side --> beefy red color --> expelled @ same time as fetal side
duncan & bleeding Right Ans - - blood loss visible externally earlier
control of bleeding @ placental site Right Ans - - post birth contractions
constrict blood vessels that supply placenta --> hemostasis
, placental separation signs Right Ans - - small gush of blood
- lengthening of cord
- rise of uterus into abd
- uterus becomes firm & rounded
small gush of blood in placental separation Right Ans - - blood escapes
from btwn placenta & decidua
lengthening of cord in placental separation Right Ans - - as placenta
descends into vagina --> cord lengthens @ vaginal introitus
rise of uterus into abd in placental separation Right Ans - - placenta
descends into vagina --> uterus is displaced upward
uterus becomes firm & rounded in placental separation Right Ans - - uterus
able to contract more firmly once placenta is expelled --> cxing rounded
firmer uterus
avoiding mismanagement of 3rd stage Right Ans - - no cord traction --> if
mom in squatting or other upright position
- no uterine massage BEFORE placental expulsion
no cord traction --> if mom in squatting or other upright position during
avoiding mismanagement of 3rd stage Right Ans - - could increase risk of
uterine inversion
no uterine massage BEFORE placental expulsion during avoiding
mismanagement of 3rd stage Right Ans - - could cx incomplete placental
seperation resulting in iatrogenic hemorrhage
expectant management of 3rd stage definition Right Ans - physiologic
management
- non interventionist approach
- delayed cord clamping
- no cord traction or if any gentle
- maternal bearing down efforts to expel placenta
- no external uterine massage following placenta expulsion
- no routine uterotonic agent administered
