CERTIFICATION EXAM Q&A 2026 STUDY
GUIDE SOLVED QUESTIONS GRADED A+
◉ Marked Variability. Answer: Amplitude range increase 25 ppm
*can be caused by :ephedrine, postdates, catecholamine release.
◉ Moderate Variability. Answer: Amplitude range 6-25pbm
◉ Acceleration. Answer: visually apparent ABRUPT increase- onset to
peak is less than 30 sec.- in FHR above the adjacent baseline. The FHR
peak is 15pbm above baseline &last 15 seconds but less than 2min from
the onset to return to baseline.
15X15
*before 32wks its 10X10
◉ Absent Variability. Answer: Amplitude range undetectable
◉ Baseline Variability. Answer: Fluctuation in the baseline FHR are
irregular in amplitude and frequency and are visually quantified as the
amplitude of the peak to trough in bpm.
, *most important indicator of fetal oxygenation, cardiac & near pathways
◉ PNS (Parasympathetic Nervous System). Answer: *Matures later in
pregnancy (32wks) and gains dominance the longer the pregnancy lasts.
*leaves medulla- becomes vagus nerve to the SA & AV nodes of
heart(conduction network)
*decrease FHR- about 10bpm
*control over variability
*interplay with sympathetic NS result in baseline variability.
◉ SNS (sympathetic nervous system). Answer: *matures early in
pregnancy @10wks,
*shunts blood to core of body
*Nerve fibers in myocardium
*Stimulation release fetal hormones "Catecholamines" Epi & Norepi
from adrenal glands. Cont. release+Asym. IUGR
*Increase FHR and Increase Fetal BP(vasoconstriction)
◉ Episodic. Answer: Event that occurs "anytime" with out contraction.
Varriables.
◉ Bradycardia. Answer: Baseline rate less than 110bpm
