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 Ans-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 Ans-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 Ans-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 Correct Ans-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. Correct Ans-
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 Correct Ans-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. Correct Ans-Define cord compression.
May lead to hypoxemia and fetal acidemia. The depth of variable deceleration's is not enough
to determine degree. Evaluate oxygenation through baseline heart rate characteristics

through rate, variability and presence or absence of accelerations. Correct Ans-Explain
persistent or recurrent cord compression concerns and what to look at.
A normal part of labor. As contractions build increased uterine pressure prevents blood from
entering/leaving the intervillous space. During the peak the fetus relies completely on its
oxygen reserve (an aerobic challenge that is not an issue for a health fetus. Correct Ans-
Explain transient interruptions in fetal oxygen supple during labor.
Chronic deficiency of placenta function, usually from an interruption of oxygenation pathway
due to abruption, mat. hypo or hypertension or other issues. Infant is not tolerant of
contractions. Can result in fetal grow restrictions (FGR) Correct Ans-Define Uteroplacental
insufficiency (UPI)
Assess baseline FHR
Determine rhythms (regular vs irregular)
ID accelerations and deceleration's but not the type of deceleration (early/late/variable)
The fetal heartbeat is best heard over the fetal back. Correct Ans-Auscultation of Fetal
Heart Sounds tell you what information?
Where is the best place to listen?
Palpation to determine presentation and position of the fetus and aid in location of fetal
heart sounds.

Head=hard, round, movable object
Buttocks=soft and irregular shape
Back=smooth, hard surface felt on one side of the abdomen
Irregular knobs and lumps on opposite side of abdomen may be hands, feet, elbows, and
knees Correct Ans-Leopold's Maneuvers
Uses sonar to track the fetal myocardium & converts movement into sound. If placed
incorrectly may pick up maternal heart.
Perform Leopold's maneuvers to find fetal back, locate heartbeat, count FHR, check mothers
pulse and compare. Correct Ans-Handheld Fetal Doppler
ID risk factors such as HTN (=vasoconstriction), Maternal smoking, abruption, post-term
pregnancy, maternal diabetes and consider FHR characteristics Correct Ans-How can you
determine if the placenta is functioning optimally?
500-700ml to the uterus per minute, 80% is directed to the placenta Correct Ans-How
much blood normally flows to the placenta?
This depends on oxygenation which is reflected in FHR variability and accelerations on the
fetal monitor tracings. Correct Ans-How many uterine contractions can be tolerated?
Umb. cord -Proplapse
