NCC EFM Exam Practice Questions
1. Oxygen is transferred from mom to fetus via the placenta through?:
Pas- sive (Simple) Diffusion
2.Intervillous space perfusion is dependent on?: Adequate Uterine Blood
Flow
3. Maternal Fetal Exchange is best promoted by which maternal position?:
-
Either Rt or Lt Lateral
4. What is transfer down the concentration gradient from higher to
lower called?: Diffusion
5. The most likely physical rationale for recurrent late decels after
epidural is?: Maternal Sympathetic Blockade
6. Which FHR pattern would be anticipated when monitoring mono-
mono twins?: Variable Decels
7. Fetus can survive in an environment w/ a PO2 equal to adult venous
blood d/t?: increased O2 carrying capacity
8. Variable decels are mediated primarily by?: baroreceptors
9. The sympathetic branch of the ANS influences FHR to?: increase
10.the average difference in baseline FHR b/w 30 & 40 weeks is?:
10bpm usually 5-6; 10 is closest
1/3
, 11.Fetal blood is most highly oxygenated in the?: Ductus Venosous
