RNC-OB Domain 2: Fetal Assessment Welcome to your RNC-OB Domain 2: Fetal Assessment 1. RNC-OB: Fetal Assessment What is the most likely fetal heart rate (FHR) pattern seen with umbilical cord compression? Early decelerations Late decelerations Variable decelerations Sinusoidal pattern None 2. RNC-OB: Fetal Assessment A fetus with anemia would most likely display which of the following Doppler ultrasound findings? Decreased systolic/diastolic 'S/D' ratio in the umbilical artery Absent end-diastolic flow in the umbilical artery Reversed end-diastolic flow in the umbilical artery Increased peak systolic velocity in the middle cerebral artery None 3. RNC-OB: Fetal Assessment Which FHR pattern is considered a sign of fetal well-being during non-stress testing (NST)? Baseline variability of less than 5 bpm Periodic accelerations with fetal movement Recurrent late decelerations Bradycardia None 4. RNC-OB: Fetal Assessment In the context of fetal monitoring, what does a 'saltatory' pattern refer to? A pattern with wide fluctuations in the baseline FHR, ranging more than 25 bpm A baseline FHR with no detectable variability A smooth, sine wave-like undulating pattern in FHR A baseline FHR that is consistently below 110 bpm None 5. RNC-OB: Fetal Assessment The presence of 'mirror artifact' in fetal heart rate monitoring is most commonly associated with which type of monitoring? Internal monitoring External ultrasound Doppler Telemetry monitoring External tocodynamometer None 6. RNC-OB: Fetal Assessment What is the primary concern associated with persistent fetal tachycardia (>160 bpm for 10 minutes or more)? Fetal sleep cycle Fetal well-being Maternal medication effect Maternal fever None 7. RNC-OB: Fetal Assessment In biophysical profile (BPP) scoring, what does a score of 6 out of 10 typically indicate? Normal, with no immediate action required Borderline, requiring possible reevaluation Abnormal, necessitating immediate delivery Abnormal, but delivery can be delayed None 8. RNC-OB: Fetal Assessment Which of the following is a key feature distinguishing early decelerations from late decelerations in fetal heart rate monitoring? The shape of the deceleration The timing of the deceleration in relation to contractions The duration of the deceleration The recovery time to baseline FHR None 9. RNC-OB: Fetal Assessment Fetal magnetocardiography is primarily used to assess: Fetal heart rate variability Fetal lung maturity Fetal cardiac electrical activity Fetal response to maternal glucose levels None 10. RNC-OB: Fetal Assessment The 'short-term variability' in fetal heart rate monitoring refers to: Fluctuations in FHR from one contraction to the next Beat-to-beat variations in FHR Changes in FHR over a 10-minute window Variations in FHR associated with fetal movements None 11. RNC-OB: Fetal Assessment Which ultrasound finding is most indicative of fetal aneuploidy? Pyelectasis Echogenic intracardiac focus Choroid plexus cyst Nuchal translucency None 12. RNC-OB: Fetal Assessment In twin-to-twin transfusion syndrome (TTTS), what fetal monitoring finding is most concerning? Discordant growth Polyhydramnios in the donor twin Oligohydramnios in the recipient twin A "stuck twin" phenomenon None 13. RNC-OB: Fetal Assessment What does the presence of sinusoidal heart rate pattern typically indicate? Normal fetal behavior Fetal anemia Umbilical cord compression Maternal drug use None 14. RNC-OB: Fetal Assessment Which condition is most likely to cause a false positive reading in fetal heart rate monitoring for bradycardia? Maternal supine hypotensive syndrome Fetal sleep cycles Maternal tachycardia Cross-talk with maternal heart rate None 15. RNC-OB: Fetal Assessment A significant decrease in fetal movement is reported by the mother. What is the first step in assessment? Immediate delivery Non-stress test Biophysical profile Contraction stress test None 16. RNC-OB: Fetal Assessment What fetal heart rate pattern is indicative of head compression during labor? Early decelerations Late decelerations Variable decelerations Prolonged decelerations None 17. RNC-OB: Fetal Assessment In the context of electronic fetal monitoring, what is the significance of a 'category III' fetal heart rate tracing? Normal and reassuring Requires continued monitoring Predictive of fetal compromise Inconclusive and requires further testing None 18. RNC-OB: Fetal Assessment Fetal scalp stimulation during labor is used to assess: Fetal oxygenation Fetal hair growth Maternal-fetal blood incompatibility Fetal response to tactile stimuli None 19. RNC-OB: Fetal Assessment The 'Montevideo units' are calculated to assess: Fetal heart rate variability Fetal breathing movements Strength of uterine contractions Amniotic fluid index None 20. RNC-OB: Fetal Assessment The use of vibroacoustic stimulation during a non-stress test is intended to: Decrease fetal movement Induce fetal sleep Elicit a fetal heart rate acceleration Measure fetal hearing None 1 out of 20 Time is Up!
