NCC EFM practice Which of the following factors can have a negative effect on uterine blood flow? a. Hypertension b. Epidural c. Hemorrhage d. Diabetes e. All of the above - correct answer e. All of the above Stimulating the vagus nerve typically produces: a. A decrease in the heart rate b. An increase in the heart rate c. An increase in stroke volume d. 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? a. Increases baseline b. 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: 1. Maternal supine hypotension 2. Maternal fever 3. Maternal dehydration 4. Unknown a. 1 and 2 b. 1, 2 and 3 c. 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: a. Low socioeconomic status b. Fetal malpresentation c. Uteroplacental insufficiency d. Uterine anomalies - correct answer c.

Fetus in breech presentation d. Decreased fetal movement - correct answer c. Fetus in breech presentation Which of the following does not affect the degree of fetal activity? a. Vibroacoustic stimulation b. Smoking c. Fetal position d. 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
