Which of the following does not affect the degree of fetal activity?
a. Vibroacoustic stimulation
,b. Smoking
c. Fetal position
d. Gestational age - ANSWER a. Vibroacoustic stimulation To be considered reactive, a
nonstress test must have:
a. 4 fetal heart rate accelerations in a 20 minute window
b. 2 fetal heart rate accelerations in a 10 minute window
c. 4 fetal heart rate accelerations in a 40 minute window
d. 2 fetal heart rate accelerations in a 20 minute window - ANSWER d. 2 fetal heart rate
accelerations in a 20 minute window
If a nonstress test is nonreactive after 40 minutes, the next step should be:
a. Have the client go home and do fetal movement counts
b. Do a biophysical profile or contraction stress test
c. Repeat the nonstress test within a week
d. Admit the client for delivery - ANSWER b. Do a biophysical profile or contraction stress test
All of the following are components of a biophysical profile except:
a. Contraction stress test
b. Assessment of fetal breathing
c. Amniotic fluid volume measurement
d. Fetal movement assessment - ANSWER a. Contraction stress test
A modified biophysical profile includes a nonstress test and:
a. Contraction stress test
b. Ultrasound assessment of fetal movement
c. Ultrasound assessment of amniotic fluid volume
d. Fetal movement counts - ANSWER c. Ultrasound assessment of amniotic fluid volume
For a contraction stress test to be interpretable, you must have a minimum of:
a. 5 contractions in a 10-minute window
b. 3 contractions in a 10-minute window
,c. 4 contractions in a 10-minute window
2 contractions in a 10-minute window - ANSWER b. 3 contractions in a 10 minute window
The vagus nerve begins maturation 26 to 28 weeks. Its dominance results in what effect to the
FHR baseline?
a. Increases baseline
b. Decreases baseline - ANSWER b. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space. - ANSWER True
T/F: The parasympathetic nervous system is a cardioaccelerator. - ANSWER False
T/F: Baroreceptors are stretch receptors which respond to increases or decreases in blood
pressure. - ANSWER True
T/F: There are two electronic fetal monitoring methods of obtaining the fetal heart rate: the
ultrasound transducer and the fetal spiral electrode. - ANSWER True
T/F: Variability can be determined with the fetoscope. - ANSWER False
T/F: Because the ultrasound transducer and toco transducer are sealed units, they can be
dipped in warm water to make cleaning easier. - ANSWER False
T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is
increased variability. - ANSWER True
T/F: All fetal monitors contain a logic system designed to reject artifact. - ANSWER True
T/F: The monitor should always be tested before starting a tracing, either external or internal
mode and labeled a test. - ANSWER True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. - ANSWER False
T/F: Both internal and external monitoring methods are equally accurate means of obtaining the
fetal heart rate and contraction patterns. - ANSWER False
T/F: The ultrasound transducer is usually placed on the side of the uterus over the baby's back,
as the fetal heart is heard best there. - ANSWER True
T/F: The spiral electrode is used to more accurately determine the frequency, duration, and
intensity of uterine contractions. - ANSWER False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not maternal. -
ANSWER False
T/F: The intrauterine catheter is used to pick up the fetal heart rate. - ANSWER False
T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has died. -
ANSWER True
, T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. - ANSWER
True
T/F: Variability and periodic changes can be detected with both internal and external monitoring.
- ANSWER True
T/F: Variable decelerations are a result of cord compression. - ANSWER True
T/F: The presence of FHR accelerations in the intrapartum and antepartum periods is a sign of
adequate fetal oxygenation. - ANSWER True
T/F: Variable decelerations are a vagal response. - ANSWER True
T/F: Late decelerations have a gradual decrease in FHR (onset to nadir 30 seconds) and are
delayed in timing with the nadir of the deceleration occurring after the peak of the contraction. -
ANSWER True
T/F: The fetal heart rate baseline can be determined during periods of marked variability. -
ANSWER False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the blood flow through
the placenta. - ANSWER True
T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration pattern in
labor. - ANSWER True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is indicated. -
ANSWER False
What is your first intervention in management of a patient experiencing variable decelerations?
a. Immediate delivery
b. Change maternal position
c. No treatment indicated
d. Oxygen
e. Stop oxytocin infusion - ANSWER b. Change maternal position
Etiology of a baseline FHR of 165bpm occurring for the last hour can be:
1. Maternal supine hypotension
2. Maternal fever
3. Maternal dehydration 4. Unknown
a. 1 and 2
b. 1, 2 and 3
