All of the above How does the fetus compensate for decreased maternal circulating volume? a. Increases cardiac output by increasing stroke volume. b. Increases cardiac output by increasing it's heart rate. c. Increases cardiac output by increasing fetal movement. correct answers b. Increases cardiac output by increasing it's heart rate. 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 answers a. A decrease in the heart rate What initially causes a chemoreceptor response? a. Epidurals b. Supine maternal position c. Increased CO2 levels d. Decreased O2 levels e. A & C f. A & B g. C & D correct answers g. C & D 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 answers b. Decreases baseline T/F: Oxygen exchange in the placenta takes place in the intervillous space. correct answers True T/F: The parasympathetic nervous system is a cardioaccelerator. correct answers False T/F: Baroreceptors are stretch receptors which respond to increases or decreases in blood pressure. correct answers True T/F: There are two electronic fetal monitoring methods of obtaining the fetal heart rate: the ultrasound transducer and the fetal spiral electrode. correct answers True T/F: Variability can be determined with the fetoscope. correct answers False T/F: Because the ultrasound transducer and toco transducer are sealed units, they can be dipped in warm water to make cleaning easier. correct answers False T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is increased variability. correct answers True T/F: All fetal monitors contain a logic system designed to reject artifact. correct answers True T/F: The monitor should always be tested before starting a tracing, either external or internal mode and labeled a test. correct answers True T/F: The paper speed on the fetal monitor should always be set at 1cm/min. correct answers False T/F: Both internal and external monitoring methods are equally accurate means of obtaining the fetal heart rate and contraction patterns. correct answers False T/F: The external toco is usually placed over the uterine fundus to pick up contractions. correct answers True T/F: The external toco gives measurable uterine pressure. correct answers False T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown origin is present. correct answers False T/F: The ultrasound transducer is usually placed on the side of the uterus over the baby's back, as the fetal heart is heard best there. correct answers True T/F: The spiral electrode is used to more accurately determine the frequency, duration, and intensity of uterine contractions. correct answers False T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not maternal. correct answers False T/F: The intrauterine catheter is used to pick up the fetal heart rate. correct answers False T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has died. correct answers True T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. correct answers True T/F: Variability and periodic changes can be detected with both internal and external monitoring. correct answers True T/F: Variable decelerations are a result of cord compression. correct answers True T/F: The presence of FHR accelerations in the intrapartum and antepartum periods is a sign of adequate fetal oxygenation. correct answers True T/F: Variable decelerations are a vagal response. correct answers 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 peak of the contraction. correct answers True T/F: The fetal heart rate baseline can be determined during periods of marked variability. correct answers False T/F: Anything that affects maternal blood flow (cardiac output) can affect the blood flow through the placenta. correct answers True T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration pattern in labor. correct answers True T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is indicated. correct answers False What is your first intervention in management of a patient experiencing variable decelerations? a. Immediate delivery b. Change maternal position c. No treatment indicated d. Oxygen e. Stop oxytocin infusion correct answers b. Change maternal position 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 What is the most probable cause of recurrent late decelerations? a. Utero-placental insufficiency b. Head compression c. Cord compression d. Maternal position change correct answers a. Utero-placental insufficiency 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 is NOT used for antepartum fetal surveillance? a. Fetal movement counting b. Antepartum fetal heart rate testing c. Biophysical profile testing d. Maternal HCG levels correct answers d. Maternal HCG levels 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 To be considered reactive, a nonstress test must have: a. 4 fetal heart rate accelerations in a 20 minute window b. 2 fetal heart rate accelerations in a 10 minute window c. 4 fetal heart rate accelerations in a 40 minute window d. 2 fetal heart rate accelerations in a 20 minute window correct answers d. 2 fetal heart rate accelerations in a 20 minute window If a nonstress test is nonreactive after 40 minutes, the next step should be: a. Have the client go home and do fetal movement counts b. Do a biophysical profile or contraction stress test c. Repeat the nonstress test within a week d. Admit the client for delivery correct answers b. Do a biophysical profile or contraction stress test All of the following are components of a biophysical profile except: a. Contraction stress test b. Assessment of fetal breathing c. Amniotic fluid volume measurement d. Fetal movement assessment correct answers a. Contraction stress test A modified biophysical profile includes a nonstress test and: a. Contraction stress test b. Ultrasound assessment of fetal movement c. Ultrasound assessment of amniotic fluid volume d. Fetal movement counts correct answers c. Ultrasound assessment of amniotic fluid volume For a contraction stress test to be interpretable, you must have a minimum of: a. 5 contractions in a 10-minute window b. 3 contractions in a 10-minute window c. 4 contractions in a 10-minute window
