b) 110-160 bpm -
correct answer ✅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. -
correct answer ✅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) -
correct answer ✅What factors impact maternal oxygen
delivery?
30-50%
lateral recumbent or semi-Fowler's -
correct answer ✅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. -
correct answer ✅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. -
correct answer ✅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. -
correct answer ✅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. -
correct answer ✅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.
