Umbilical cord compression An appropriate treatment for recurrent variable decelerations with moderate variability during second stage pushing is: A. Amnioinfusion B. Modification of pushing efforts C. Oxygen at 10 liters per nonrebreather face mask. correct answers B. Modification of pushing efforts The Primary purpose of the ...

EFM paper speed correct answers 3cm/ minute Ultra sound (EFM) correct answers US transducer detects motion through ultrahigh frequency sound waves - it determines FHR by auto correlation compares successive reflected ultra sound waveforms at many points FSE correct answers fetal scalp electrode (ISE) measures interval between R waves Value of EFM correct answers used as a screen test, not considered diagnostic - normal EFM tracing = grater than 99% chance fetus with not have neurologic ...

The fetal spiral electrode measures the A. Peaks of the Doppler waveforms B. R to R intervals of the fetal heart C. ST segments of the fetal ECG correct answers B. R to R intervals of the fetal heart The optimal location for the ultrasound transducer for the fetus correct answers the fetal back First step when contraction pattern is weird with IUPC in place correct answers re zero the IUPC Membranes ruptured 60 minutes ago and now you see prolonged deceleration, first step: correct a...

Why use fetal monitoring? correct answers Primary goal is to prevent fetal and maternal morbidity and mortality (prevent injury and death to mother and/ or baby), to prevent bad patient outcomes. What percent of babies who experience a suboptimal event while being fetal monitored, develop cerebral palsy? correct answers 3% of babies with poor tracing develop cerebral palsy What are most sentinel events due to? correct answers Poor communication between providers. Most errors are traceable ...

Uterine contractions are quantified as correct answers the number of contractions present in a 10 min window Normal frequency of uterine contractions correct answers ≤5 contractions in 10 min, averaged over a 30 min window Tachysystole is correct answers >5 contractions in 10 min, averaged over a 30 min window.
