PRACTICE TEST 2026 ACTUAL QUESTIONS
WITH ANSWERS GRADED A+
◉ Uterus. Answer: 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. Answer: 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. 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.. 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). Answer: What
factors impact maternal oxygen delivery?
◉ 30-50%
lateral recumbent or semi-Fowler's. 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..
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.. 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.. 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.. 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.
, D) Continuous Fetal Monitor
E) Administer ephedrine per MD order
◉ systolic BP >= 140mm hg, a diastolic BP>= 90 mm hg or MAP of
>=105. Answer: 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.. Answer: 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. Answer: 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.. Answer: Define
cord compression.
◉ May lead to hypoxemia and fetal acidemia. The depth of variable
deceleration's is not enough to determine degree. Evaluate oxygenation
