2024 INTERMEDIATE FETALMONITORING EXAM WITH
CORRECT ANSWERS
How does a toco work? - CORRECT-ANSWERSdetects changes in shape of
abdomen resulting from uterine tension
5 Physiological Goals - CORRECT-ANSWERS1. support maternal coping and
labor progress
2. maximize uterine blood flow
3. maximize umbilical circulation
4. maximize oxygenation
5. maintain appropriate uterine activity
Why is emotional support important? - CORRECT-ANSWERSdecreases
catecholamine response and increases fetal oxygenation
Interventions to maximize blood flow - CORRECT-ANSWERS-reduce
anxiety/pain
-maternal positioning (lateral)
-hydration
-medication to reduce uterine contractions (decrease pit or tocolytics)
Interventions to maximize umbilical circulation - CORRECT-ANSWERS-
maternal position
-amnioinfusion (closely monitor resting tone)
Interventions to maximize oxygenation - CORRECT-ANSWERS-maternal
breathing
-supplemental oxygen (cautious use, not 1st line, not for prophylactic use)
Interventions to maintain appropriate uterine activity - CORRECT-ANSWERS-
oxytocin
-fluid bolus
-position change
Baseline Rate - CORRECT-ANSWERS-approximate mean FHR rounded to
increments of 5bp during a 10 min segment
, - duration must be at least 2 min. or the baseline for that period is
indeterminate
Bradycardia - CORRECT-ANSWERSbaseline rate less than 110 bpm
Tachycardia - CORRECT-ANSWERSbaseline of greater than 160 bpm
Baseline variability - CORRECT-ANSWERSfluctuations in baseline FHR that are
irregular in amplitude and frequency
Absent variability - CORRECT-ANSWERSamplitude range undetectable
Minimal variability - CORRECT-ANSWERSamplitude range > undetectable but
<5/min
Moderate variability - CORRECT-ANSWERSamplitude ranges 6-25 bpm
Marked variability - CORRECT-ANSWERSamplitude range greater than 25
bpm
Acceleration - CORRECT-ANSWERSvisually apparent abrupt (<30 sec to
peak) increase in FHR above baseline for less than 2 minutes
-15bpmx15sec for 32 weeks and up
-10bpmx10sec for less than 32 weeks
Prolonged Acceleration - CORRECT-ANSWERSacceleration lasting longer than
2 minutes but less than 10 minutes.
Early Deceleration - CORRECT-ANSWERSA visually apparent usually
symmetrical gradual (more than 30 sec) decrease in FHR and return to
baseline associated with a contraction
-nadir occurs at the same time as the peak of the contraction
Late Deceleration - CORRECT-ANSWERSvisually apparent, usually
symmetrical gradual decrease in FHR and return to baseline associate with a
contraction
-delayed in timing with the nadir occurring after the peak of the contraction
Variable Deceleration - CORRECT-ANSWERSvisually apparent abrupt
decrease in FHR
-decrease is 15 bpm lasting for more than 15 sec but less than 2 minutes
Prolonged Deceleration - CORRECT-ANSWERSvisually apparent decrease in
FHR that is at least 15 bpm lasting greater than or equal to 2 minutes but
less than 10 minutes from onset to return to baseline
