NCC EFM EXAM QUESTIONS AND VERIFIED ANSWERS
reactive NST (normal)
two or more fetal heart rate accelerations (15 above baseline and last 15 sec) within 20
min
Nonreactive NST
No accelerations present after 40 min of monitoring
FHR decelerations during NST warrants...
delivery
Fetal Acoustic Stimulation Test
sound and vibration stimulation of fetus in adjunct to NST
Nonreactive FAST
After one application of stimulation, fetus does not respond with acceleration
Managment of Reactive NST
Resume routine monitoring (1-2x per week)
Managment of Non-reactive NST
Back up test with BPP or CST/OCT
Components of BPP
1. Fetal breathing
2. Fetal movement
3. Fetal tone
4. AFV
5. Fetal HR
Parts of BPP which assesses acute central nervous system function
1. Fetal HR
2. Fetal tone
3. Fetal movement
4. Fetal breathing
Parts of BPP which assesses long term adequacy of placental function
AFV
BPP Scoring
, 2 points for each normal variable (Max = 10)
0 points for each abnormal variable
Normal BPP score
8-10 with normal AFV
Suspicous BPP score
6
Repeat testing following day
BPP score a/w perinatal M&M
Less than 6
Modified BPP
NST + AFV
Normal modified BPP
MUST have AFV greater than 2 cm + normal NST without deccels
Managment of abnormal modified BPP
Back up test with regular BPP or CST/OCT
Clinically significant deccels
Variable, late, and prolonged (greater than 2 min, less than 10 min)
FHT monitoring for low-risk women
Active phase of 1st stage: q30 mins
2nd stage: q15 mins
FHT monitoring for high-risk women
Active phase of 1st stage: q15 mins
2nd stage: q5 mins
Uterine cxt during labor decrease perfusion at level of...
intervillous space
Fetal compensations for periods of oxidative stress during labor...
- Increased affinity for oxygen in fetal Hgb
- Vascular shunts toward vital organs
- Higher fetal CO
- High glycogen storage in myocardium
Fetal vascular shunts
