EFM Test exam 2023 with 100% correct answers

Baseline Rate Approx mean FHR rounded to increments of 5 bpm during a 10 min segment. Minimum baseline duration must be 2 min, excluding periods of marked variability or segments of baseline that differ by 25 bpm. Bradycardia Less than 110 bpm Tachycardia Greater than 160 bpm Acceleration Visually abrupt increase above baseline (onset to peak 30sec) that is 15 by 15, or 10 by 10 before 32 weeks Early deceleration Gradual decrease in FHR (30 sec) with the nadir occuring at the same time as the peak. In most cases, onset and recovery occur simultaneously with the contraction. Late deceleration Gradual decrease in baseline associated with uterine contraction. Nadir occurs after the peak of the contraction. Onset, peak, and recovery occur after onset, peak, and ending of uterine contraction. Variable deceleration Visually abrupt decrease in FHR, (onset to beginning of nadir is 30sec) Decrease is 15bpm, lasting 15sec, and less than 2 min. Prolonged deceleration Decrease greater than or equal to 15 bpm, lasting greater than or equal to 2 min, and less than 10 min from onset to return to baseline. Recurrent deceleration Occurring with greater than or equal to 50% of contractions during any 20 min segment. acidemia Increase H+ in blood acidosis Increase H+ in tissue Hyperstimulation Persistent pattern of more than 5 contractions in 10 min, contractions lasting 2 min or longer, or contractions of normal duration occuring withing 1 min of each other FSE reflects _____ wave R wave. FSE detects the PQRST complex, then filters everything out but R wave Contraindications to FSE application HIV, chronic hepatitis, HSV or other untreated STDs, mother who is a known hemophilia carrier when sex of fetus is unknown Parasympathetic nervous system influences the heart via the ______ nerve Vagus Origination/Termintation points of parasympathetic nerve fibers Medulla Oblongata/SA and AV node Stimulation of parasympathetic nerve fibers _____ (slows or speeds up) FHR slows
