The etiology of a late deceleration is {Ans: uteroplacental insufficiency}Normal frequency of uterine contractions {Ans: ≤5 contractions in 10 min, averaged over a 30 min window}FHR patterns are defined by the characteristics of {Ans: baseline, variability, accelerations, and decelerations}An early deceleration is a visually apparent usually (A) and (B) decrease of and return of the FHR associated with a uterine contraction {Ans: A. symmetrical B. gradual}To be called an acceleration, the peak must be (A) an the acceleration must last (B) from the onset to the return to baseline FHR {Ans: A. ≥ 15 bpm B ≥ 15 seconds}In an early deceleration, the nadir of the deceleration occurs {Ans: at the same time as the peak of the contraction}
