BSNC 5000 MODULE 2 OB EXAM
QUESTIONS WITH CORRECT DETAILED
ANSWERS
what is the third stage of labour - Answer-last from the birth of fetus until placenta is
delivered
- can last 3-5min or up to an hour
- when mom and baby have skin to skin contact for the first time
when does the placenta separate from mom - Answer-placenta normally separates with
3-4 strong uterine contractions after infant born
what are the benefits to skin-to-skin contact right after birth - Answer-- create warm
environment (baby cold)
- reduces anxiety and fear
- decreases catecholamine production and increased oxytocin production = facilitation
placental separation
what is the fourth stage of labour - Answer-begins with the delivery of placenta and
includes at least the first 2 hours after birth
- time of attachment, bonding, and breastfeeding
what is the mechanism of labour - Answer-- presenting part of baby is large in
proportion to passageway, fetus must adapt to birth canal during descent
- turns and other adjustments necessary in human birth process
- 7 cardinal movements during labour (vertex presentation)
assessment of fetus during labour - Answer-- contraction will decrease intrauterine
blood flow -> interventions to protect mom and baby
- auscultate HR assessing pattern
- electronic fetal monitoring -> decreased mobility and increased use of analgesics (not
good)
- every 15-20min post contraction to assess how they doing
what are the 4 T's - Answer-- tone
- trauma
- thrombin
- tissue
, what are the 7 cardinal movements of mechanism of labour in vertex presentation -
Answer-- engagement
- descent
- felxion
- internal rotation
- extension
- external rotation
- expulsion
what is the engagement movement - Answer-- When biparietal diameter of head passes
the pelvic inlet, head is said to be engaged in pelvic inlet
- asynclitism: head usually engages in pelvis in a synclitic position (parallel to the axis of
the pelvis. used of the planes of the fetal head in labor)
What is the descent movement - Answer-refers to progress of the presenting part
through the pelvis
what is the flexion movement - Answer-When descending head meets resistance from
the cervic, pelvic wall, or pelvic floor, normally flexes so chin is brought closer into cloer
contact with fetal chest
what is the internal rotation movement - Answer-Maternal pelvic inlet is widest in
transverse diameter, fetal head passes the inlet into true pelvis in occipitotransverse
position
what is the extension movement - Answer-When fetal head reaches perineum for birth,
it is deflected anteriorly by perineum
what is the expulsion movement - Answer-After birth of shoulders, head and shoulders
are lifted up toward mothers pubic bone, and trunk of baby is born by flexing it laterally
in direction of symphysis pubis
what is effacement - Answer-the shortening and thinning of the cervix during first stage
of labour
what is dilation - Answer-dilation of cervix is the enlargement or widening of the cervical
opening
during the first stage of labour what is completed during the uterine activity assessment
- Answer-- contractions monitored
- frequency
- intensity
- duration
resting tone
