basics
1.a) Frequency
b) Duration: Which contraction characteristics can be assessed with a
tocody- namometer?
a) Frequency
b) Duration
c) Intensity
2.Uterus: All Fetuses of mothers in labor experience an interruption of
the oxygena- tion pathway at which point?
3.a) Throughout labor and delivery unless the use of a more accurate
method is clearly indicated: The FHR can be monitored using doppler
ultrasound?
a)Throughout labor and delivery unless the use of a more accurate
method is clearly indicated
b) Internally
c) Only early in labor
d)The FHR cannot be monitored by doppler ultrasound
4.b) 110-160 bpm: What is the normal range for FHR base line in a term
infant?
a) 80-120 bpm
b) 110-160 bpm
c) 140-180bpm
d) it depends on the sex of the fetus
5.Mother's inhalation to lungs to mat. circulatory system to hemoglobin in
RBC's to bloodstream in uterus. Uterus to spiral arteries to placenta to
inter- villous space to travel via simple diffusion into the villi. The capillaries
to the umb. vein to the fetus.
The umb. artery sends waste (CO2) to the intervillous space to the mothers
venous system.: Trace the flow of oxygen from mother to fetus and back.
6.1. Mother (blood plasma, cardiac output, hemoglobin concentration &
O2 saturation)
2. Placenta/intervillous space (uterine contractions & calcification's)
3. Fetus (vagal response aka decel or cord compression): What factors
impact maternal oxygen delivery?
7.30-50%
lateral recumbent or semi-Fowler's: By what % does maternal cardiac
output increase above the non-pregnant state and what position helps
this uteroplacental blood flow?
8.>5 contractions in 10 min (more frequently than Q 2 min) averaged over
30 min window.

2. Admin IV fluid bolus.
3. Admin 0.25mg terbutaline SQ.
4. Admin O2 10L via non rebreather face mask.: List interventions for
tachysystole contractions.
10.higher conc. to lower concentration.
1. Oxygen from maternal (higher) to fetal compartment (lower) to fetal hgb
then transported to fetal tissue.
2. CO2 returns to intervillous space by passive diffusion and is removed
by the mat. venous system.: Describe passive diffusion as related to the
maternal placental fetal system.
11.Place her in lateral position, & increase IV fluids. If no improvement may
need to give epi to increase vascular tone.: Maternal hypotension is a
potential side effect of regional anesthesia and analgesia. What nursing
interventions could you use to raise the client's blood pressure? Choose
all that apply.
A) Place the woman in a supine position.
B) Place the woman in a lateral position.
C) Increase intravenous (IV) fluids.
D) Continuous Fetal Monitor
E) Administer ephedrine per MD order
12.systolic BP >= 140mm hg, a diastolic BP>= 90 mm hg or MAP of >=105: -
Define maternal hypertension (gestational).
13.17g/dl, fetal hgb has a higher oxygen affinity than an adult to develop in
an oxygen poor environment. The fetal circulatory pattern ensures blood
with higher O2 and nutrition content is delivered to the vital organs (brain
and heart) to tolerate the stress of labor.: What is the normal expected
value for a term fetal HGB?

jelly. O2 (high content) travels via the vein
CO2 travels via 2 arteries back to placenta: detail the umbilical orc

15.A decrease of blood flow and O2 delivery to fetus & increases CO2 level
in fetus.
Transient cord compression can be common in labor. Variable FHR decel's is
frequently associated with cord compression.: Define cord
