NUR 202 EXAM 1 OB QUESTIONS AND ANSWERSLeopold's maneuvar has how many maneuvars? - Answers-4
If baby was LOA you would put fetal monitor where on mothers abd? - Answers-LLQ
Fetal HR is <110 for 10 mins this is called - Answers-Fetal bradycardia
What is the cx of early decelerations - Answers-Head compression
What is the priority nursing intervention for variable deceleration? - Answers-Reposition
mother. Baby is compressing umbilical cord
What does a late deceleration mean? - Answers-Deoxygenated (HR decreases after peak
of contraction)
The purpose of this is to evaluate how to fetus tolerates labor and to identify possible
hypoxic insult to the fetus during labor - Answers-Fetal surveillance
Oxygen for the fetus is received from? - Answers-The placenta
Fetal hypoxia, cord compression, placenta detachment does what to the fetal HR -
Answers-Decreases it. Bradycardia
Fetal tachycardia can results from what? - Answers-Infection
Mix of maternal and fetal' blood occurs and mother develops antibodies. This can cause
the fetus to become what? - Answers-Anemic
Fetoscope is useful for fetal - Answers-Cardiac dysrhythmias
Doppler ultrasound is common in actual practice, useful if baby is _____ and maternal
mother has _______ - Answers-Early, increased maternal abd fat
The best way to access fetal well being would be to start listening in FHR when during an
contraction so that late decelerations could be detected? - Answers-At the end of one (not
after one)
During intermittent auscultation to establish a baseline the FHR is assessed for how long
after a contraction - Answers-A full minute
FHR is heard most clearly at the fetal? - Answers-Back
,In a cephalic presentation the FHR is best heard in which quadrant - Answers-Lower
quadrant
In a breech presentation the FHR is best heard at or above the level of? - Answers-
Maternal umbillicus
External monitoring can be used while the membranes are still intact and cervix is not
dilate, but also can be used with ruptured membranes and a dilating cervix. True or false?
- Answers-True
Tocotransducer "toco" is placed over the fundus. This detects changes in abd contour to
measure what with a pressure sensor? - Answers-Uterine activity
This requires ROM, about 2 cm of cervical dilation, presenting part low enough to allow
placement, and skilled practitioner available to insert. This is what type of monitoring
device - Answers-Internal fetal monitoring
FHR with scalp electrode and uterine activity with intrauterine pressure Cather (IUPC) are
both internal fetal monitoring devices. Which one requires ROM and which one doesn't?
- Answers-Scalp electrode requires ROM
IUPC does not require ROM
Evaluation of fetal monitoring strips what order do you go in? - Answers-1st baseline rate
2nd variability
3rd any pattern of rate change from baseline
Uterine activity is evaluated by what 4 things? - Answers-Frequency, duration, intensity
of contraction, and uterine resting tone (min of 30 secs)
Most accurate in extreme fetal oxygenation and acid base balance issues - Answers-
Fetal monitoring strip
Normal average fetal HR is - Answers-110-160
FHR >160 for atleast 10 minutes is - Answers-Tachycardia
FHR <110 for atleast 10 minutes is - Answers-Bradycardia
Less than 5 beats change is what kind of variability - Answers-Minimal variability
6-25 beats change is what kind of variability - Answers-Moderate variability (this is
normal)
, Greater than 25 beats change is what kind of variability - Answers-Marked variability
Evaluation of what clarifies how a fetus is tolerating stress of labor including factors that
cause hypoxia and considered a significant component of FHR trading - Answers-
Variability
Fetal sleep (20-40 mins), narcotics, sedative drugs like mag sulfate, ETOH, illicit drugs,
fetal tachycardia, gestational age <28 weeks, fetal anomalies affecting CNS, severe
hypoxia, abnormalities of heart or CNS, maternal acidemia or hypoxia. These can play a
factor in decreased - Answers-Variability
Periodic changes is the HR in response to what - Answers-Contractions
Reductions in the mothers circulating blood volume reduces perfusion of the intervillous
spaces with oxygenated maternal blood. True or false? - Answers-True
Hemorrhage, epidural block hypotension, maternal hypertension, lowered oxygen
level in maternal blood, maternal acid base imbalance, asthma, pulmonary infection,
smoking. These are all red flags to what prob imposed on fetus - Answers-Reduced
perfusion of the intervillous spaces with oxygenated maternal blood
Dilation is dependent of the pressure of the presenting part and the contraction and
retraction of the uterus. True or false? - Answers-True
Contractions over 90-120 seconds, too frequent closer than every 2 minutes, or too short
less than 30 seconds of complete relaxation. This is what kind of uterine activity -
Answers-Hypertonic uterine activity
Oligohydramnios (low amniotic fluid) can cause what to the umbilical cord - Answers-
Compression. Inadequate fluid to cushion cord
Temporary increase is FHR, 15 beat increase for 15 seconds, associated with fetal
movement, may occur with vag exam, uterine contractions, and mild cord compression
(breech), may be non periodic, reassuring, fetus has responsive to CNS and is not in
acidosis - Answers-Accelerations
Occur only during contractions as the fetal head is compressed, returns to baseline fetal
heart rate by the end of the contraction, are mirror images of contractions when
contraction is at its highest the FHR is at its lowest, is not associated with fetal
compromise, requires no additional interventions except document - Answers-Early
decelerations
Begins well after the contraction begins (often near the peak), return to baseline after the
contraction ends, reflect impaired placental exchange or uteroplacental insufficiency,
requires nursing intervention to improve placental blood flow and fetal oxygen supply. -
Answers-Late decelerations
