CERTIFICATION EXAM QUESTIONS AND ANSWERS
(2023-20240 VERIFIED ANSWERS
Which of the following factors can have a negative effect on uterine blood flow?
• Hypertension
• Epidural
• Hemorrhage
• Diabetes
• All of the above - e. All of the above
How does the fetus compensate for decreased maternal circulating volume?
• Increases cardiac output by increasing stroke volume.
• Increases cardiac output by increasing it's heart rate.
• Increases cardiac output by increasing fetal movement.
• - b. Increases cardiac output by increasing it's heart rate.
Stimulating the vagus nerve typically produces:
• A decrease in the heart rate
• An increase in the heart rate
• An increase in stroke volume
• No change - a. A decrease in the heart rate
What initially causes a chemoreceptor response?
• Epidurals
• Supine maternal position
• Increased CO2 levels
• Decreased O2 levels
• A&C
• A&B
• C & D - g. C & D
The vagus nerve begins maturation 26 to 28 weeks. Its dominance results in
whateffect to the FHR baseline?
• Increases baseline
,• Decreases baseline - b. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space. - True
T/F: The parasympathetic nervous system is a cardioaccelerator. - False
T/F: Baroreceptors are stretch receptors which respond to increases or decreases in
blood pressure. - True
T/F: There are two electronic fetal monitoring methods of obtaining the fetal
heartrate: the ultrasound transducer and the fetal spiral electrode. - True
T/F: Variability can be determined with the fetoscope. - False
T/F: Because the ultrasound transducer and toco transducer are sealed units, they
canbe dipped in warm water to make cleaning easier. - False
T/F: The most common artifact with the ultrasound transducer system for fetal
heartrate is increased variability. - True
T/F: All fetal monitors contain a logic system designed to reject artifact. - True
T/F: The monitor should always be tested before starting a tracing, either
external orinternal mode and labeled a test. - True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. - False
T/F: Both internal and external monitoring methods are equally accurate means of
obtaining the fetal heart rate and contraction patterns. - False
T/F: The external toco is usually placed over the uterine fundus to pick up
contractions. - True
T/F: The external toco gives measurable uterine pressure. - False
,T/F: The fetal spiral electrode can be placed when vaginal bleeding of
unknownorigin is present. - False
T/F: The ultrasound transducer is usually placed on the side of the uterus
over thebaby's back, as the fetal heart is heard best there. - True
T/F: The spiral electrode is used to more accurately determine the frequency,
duration, and intensity of uterine contractions. - False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal,
not maternal. - False
T/F: The intrauterine catheter is used to pick up the fetal heart rate. - False
T/F: The internal spiral electrode may pick up the maternal heart rate if the baby
hasdied. - True
T/F: Fetal arrhythmias can be seen on both internal and external monitor
tracings. -True
T/F: Variability and periodic changes can be detected with both internal and
externalmonitoring. - True
T/F: Variable decelerations are a result of cord compression. - True
T/F: The presence of FHR accelerations in the intrapartum and antepartum
periods isa sign of adequate fetal oxygenation. - True
T/F: Variable decelerations are a vagal response. - 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 peakof the contraction. - True
, T/F: The fetal heart rate baseline can be determined during periods of marked
variability. - False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the
blood flow through the placenta. - True
T/F: Variable decelerations are the most frequently seen fetal heart rate
decelerationpattern in labor. - True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean
section is indicated. - False
What is your first intervention in management of a patient experiencing variable
decelerations?
• Immediate delivery
• Change maternal position
• No treatment indicated
• Oxygen
• Stop oxytocin infusion - b. Change maternal position
Etiology of a baseline FHR of 165bpm occurring for the last hour can be:
• Maternal supine hypotension
• Maternal fever
• Maternal dehydration
• Unknown
• 1 and 2
• 1, 2 and 3
c. 2, 3 and 4 - c. 2, 3 and 4
What is the most probable cause of recurrent late decelerations?
• Utero-placental insufficiency
• Head compression
• Cord compression
• Maternal position change - a. Utero-placental insufficiency
