TEST 2026 ANSWERS VERIFIED
◉ 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. Answer:
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..
Answer: 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). Answer: 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.. Answer:
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. Answer: 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.. Answer: Handheld
Fetal Doppler
◉ ID risk factors such as HTN (=vasoconstriction), Maternal
smoking, abruption, post-term pregnancy, maternal diabetes and
consider FHR characteristics. Answer: How can you determine if the
placenta is functioning optimally?
,◉ 500-700ml to the uterus per minute, 80% is directed to the
placenta. Answer: 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.. Answer: How many
uterine contractions can be tolerated?
◉ Umb. cord -Proplapse
Mat. inhalation -Asthma
Placenta -Calcification
Uterus -Tachysystole
Fetus -Rh isoimmunization (fetal anemia)
Mat. circulation -Hypertension. Answer: What conditions impact the
following pathways:
Umbilical cord
Maternal inhalation
Placenta
Uterus
Fetus
Maternal circulation
◉ Helps Assess Fetal Well-Being
, Can Use external Doppler US Device or Internal Fetal Scalp Electrode
Should Be Monitored Every 30 Minutes in Stage I, Every 15 Minutes
in Stage 2. Answer: Fetal Heart Rate Monitoring (two methods)
◉ 10-20 mm Hg (this is an arbitrary #)
Toco detects increases and decreases but can not quantify pressure..
Answer: When using toco what do you set the uterine resting tone or
baseline to?
What is toco measuring?
◉ Between 5-20 mm Hg
IUPC gives a quantified measure of intrauterine pressure.. Answer:
When using IUPC what is the resting tone or baseline?
What is the IUPC measuring?
◉ -Duration (the time elapsed from beginning to end) 60-80
seconds = 6-8 small boxes
-Frequency (time elapsed from beginning of one contraction to the
beginning of the next) 2 minutes = 2 darker vertical lines. Answer:
What is the duration?
What is the frequency?
