b) Duration - ACCURATE ANSWERS✔✔ Which contraction
characteristics can be assessed with a tocodynamometer?
a) Frequency
b) Duration
c) Intensity
Uterus - ACCURATE ANSWERS✔✔ All Fetuses of mothers in labor
experience an interruption of the oxygenation pathway at which point?
a) Throughout labor and delivery unless the use of a more accurate
method is clearly indicated - ACCURATE ANSWERS✔✔ 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
,b) 110-160 bpm - ACCURATE ANSWERS✔✔ 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
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
intervillous 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. - ACCURATE ANSWERS✔✔ Trace the flow
of oxygen from mother to fetus and back.
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) - ACCURATE
ANSWERS✔✔ What factors impact maternal oxygen delivery?
30-50%
lateral recumbent or semi-Fowler's - ACCURATE ANSWERS✔✔ By
what % does maternal cardiac output increase above the non-pregnant
state and what position helps this uteroplacental blood flow?
,>5 contractions in 10 min (more frequently than Q 2 min) averaged over
30 min window.
Caused by oxytocin, aminoinfusion or in rare cases spontaneously. -
ACCURATE ANSWERS✔✔ Define tachysystole contractions and the
cause of.
Maintaining mat. volume, mat. positioning, intravenous hydration.
Decreasing mat. pain/anxiety.
1. Reposition pt to side.
2. Admin IV fluid bolus.
3. Admin 0.25mg terbutaline SQ.
4. Admin O2 10L via non rebreather face mask. - ACCURATE
ANSWERS✔✔ List interventions for tachysystole contractions.
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. - ACCURATE ANSWERS✔✔ Describe
passive diffusion as related to the maternal placental fetal system.
Place her in lateral position, & increase IV fluids. If no improvement
may need to give epi to increase vascular tone. - ACCURATE
ANSWERS✔✔ 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
systolic BP >= 140mm hg, a diastolic BP>= 90 mm hg or MAP of
>=105 - ACCURATE ANSWERS✔✔ Define maternal hypertension
(gestational).
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. - ACCURATE
ANSWERS✔✔ What is the normal expected value for a term fetal
HGB?
1 vein, 2 arteries encased in wharton's jelly.
O2 (high content) travels via the vein
CO2 travels via 2 arteries back to placenta - ACCURATE
ANSWERS✔✔ detail the umbilical cord
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. - ACCURATE
ANSWERS✔✔ Define cord compression.
