Study Guide for Week 2
Content (Chapters 6 &
9)
The next quiz will ask about the material that is on the study guide. I will expect
you to know NST (accelerations, reactive/nonreactive), the definitions about the
components of a fetal heart rate tracing, VEAL- CHOP (the mnemonic we used
for decelerations and what causes them) since these concepts were
introduced in OB CCC. FHR strips will be on the quiz. Please also take a look
at the interventions for the decelerations- you should be familiar with them
from CCC as well.
