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 - 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 - 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 - b. Decreases baseline T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is increased variability. - True T/F: All fetal monitors contain a logic system designed to reject artifact. - True T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. - TrueT/F: Variability and periodic changes can be detected with both internal and external monitoring. - True T/F: Variable decelerations are a vagal response. - True T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration pattern in labor. - 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 - 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 - c. Uteroplacental insufficiency Which of the following conditions is not an indication for antepartum fetal surveillance? a. Gestational hypertension b. Diabetes in pregnancy c. Fetus in breech presentation d. Decreased fetal movement - c. Fetus in breech presentationWhich of the following does not affect the degree of fetal activity? a. Vibroacoustic stimulation b. Smoking c. Fetal position d. Gestational age - a. Vibroacoustic stimulation T/F: Umbilical cord influences that can alter blood flow include true knots, hematomas, and number of umbilical vessels. - True T/F: Low amplitude contractions are not an early sign of preterm labor. - False T/F: Corticosteroid administration may cause an increase in FHR accelerations. - False T/F: Corticosteroid administration may cause an increase in FHR. - True T/F: Contractions cause an increase in uterine venous pressure and a decrease in uterine artery perfusion. - True As a result of the intrinsic fetal response to oxygen deprivation, increased catecholamine levels cause the peripheral blood flow to decrease w
