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 answers 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 answers 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 correct answers 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 answers a. Vibroacoustic stimulation T/F: Umbilical cord influences that can alter blood flow include true knots, hematomas, and number of umbilical vessels. correct answers True T/F: Low amplitude contractions are not an early sign of preterm labor. correct answers False T/F: Corticosteroid administration may cause an increase in FHR accelerations. correct answers False T/F: Corticosteroid administration may cause an increase in FHR. correct answers True T/F: Contractions cause an increase in uterine venous pressure and a decrease in uterine artery perfusion. correct answers 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? A. Increase BP and increase HR B. Increase BP and decrease HR C. Decrease BP and increase HR D. Decrease BP and decrease HR correct answers B. Increase BP and decrease HR 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? A. True knot B. Gestational diabetes C. Umbilical cord entanglement D. Oligohydramnios correct answers B. Gestational diabetes All of the following are likely causes of prolonged decelerations except: A. Uterine tachysystole B. Prolapsed cord C. Maternal hypotension D. Maternal fever correct answers D. Maternal fever All of the following could likely cause minimal variability in FHR except A. Magnesium sulfate administration B. Fetal sleep cycle C. Narcotic administration D. Ephedrine administration correct answers 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 D. 400 correct answers 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 D. 7.41 correct answers 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: a. Give the woman oxygen by facemask at 8-10 L/min b. Position the woman on her opposite side c. Increase the rate of the woman's intravenous fluid d. Continue to observe and record the normal pattern correct answers d. Continue to observe and record the normal pattern
