NCC EFM Exam practice 200 Questions and Answers Verified 2023/2024 Which of the following factors can have a negative effect on uterine blood flow?

• Hypertension
• Epidural
• Hemorrhage
• Diabetes
• All of the above - Correct Answer e. All of the above

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 - Correct Answer a. A decrease in the heart rate

The vagus nerve begins maturation 26 to 28 weeks. Its dominance results in what effect to the FHR baseline?

• Increases baseline
• Decreases baseline - Correct Answer b. Decreases baseline

T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is increased variability. - Correct Answer True T/F: All fetal monitors contain a logic system designed to reject artifact. - Correct Answer True T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. - Correct Answer True T/F: Variability and periodic changes can be detected with both internal and external monitoring. - Correct Answer True

T/F: Variable decelerations are a vagal response. - Correct Answer True

T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration pattern in labor. - Correct Answer True

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 1 / 3

• 2, 3 and 4 - Correct Answer c. 2, 3 and 4

The most prevalent risk factor associated with fetal death before the onset of labor is:

• Low socioeconomic status
• Fetal malpresentation
• Uteroplacental insufficiency
• Uterine anomalies - Correct Answer c. Uteroplacental insufficiency

Which of the following conditions is not an indication for antepartum fetal surveillance?

• Gestational hypertension
• Diabetes in pregnancy
• Fetus in breech presentation
• Decreased fetal movement - Correct Answer c. Fetus in breech presentation

Which of the following does not affect the degree of fetal activity?

• Vibroacoustic stimulation
• Smoking
• Fetal position
• Gestational age - Correct Answer a. Vibroacoustic stimulation

T/F: Umbilical cord influences that can alter blood flow include true knots, hematomas, and number of umbilical vessels. - Correct Answer True T/F: Low amplitude contractions are not an early sign of preterm labor. - Correct Answer False T/F: Corticosteroid administration may cause an increase in FHR accelerations. - Correct Answer False T/F: Corticosteroid administration may cause an increase in FHR. - Correct Answer True T/F: Contractions cause an increase in uterine venous pressure and a decrease in uterine artery perfusion. - Correct Answer True As a result of the intrinsic fetal response to oxygen deprivation, increased catecholamine levels cause the peripheral blood flow to decrease while the blood flow to vital organs increases. These flow changes along with increased catecholamine secretions have what effect on fetal blood pressure and fetal heart rate?

• Increase BP and increase HR
• Increase BP and decrease HR
• Decrease BP and increase HR
• Decrease BP and decrease HR - Correct Answer B. Increase BP and decrease HR 2 / 3

During a term antepartum NST (non-stress test), you notice several variable decelerations that decrease at least 15 bpm and last at least 15 sec long. Which of the following is the least likely explanation?

• True knot
• Gestational diabetes
• Umbilical cord entanglement
• Oligohydramnios - Correct Answer B. Gestational diabetes

All of the following are likely causes of prolonged decelerations except:

• Uterine tachysystole
• Prolapsed cord
• Maternal hypotension
• Maternal fever - Correct Answer D. Maternal fever

All of the following could likely cause minimal variability in FHR except

• Magnesium sulfate administration
• Fetal sleep cycle
• Narcotic administration
• Ephedrine administration - Correct Answer D. Ephedrine administration

When an IUPC has been placed, Montevideo units must be ___ or greater for adequate cervical change to occur.

A. 100

B. 200

C. 300

• 400 - Correct Answer B. 200

What would be a suspected pH in a fetus whose FHTs included recurrent late decelerations during labor?

A. 7.10

B. 7.26

C. 7.32

• 7.41 - Correct Answer A. 7.10

The nurse notes a pattern of decelerations on the fetal monitor that begins shortly after the contraction and returns to baseline just before the contraction is over. The correct

nursing response is to:

• Give the woman oxygen by facemask at 8-10 L/min
• Position the woman on her opposite side
• Increase the rate of the woman's intravenous fluid
• Continue to observe and record the normal pattern - Correct Answer d. Continue to

observe and record the normal pattern Determining the FHR baseline requires the nurse to approximate the mean FHR rounded to increments of 5 bpm during a ___-minute window (excluding accelerations and decelerations).
