Fetal Heart Monitoring Quiz
Prior to 32 weeks gestation, a fetal heart rate acceleration is defined as an increase in
FHR that must be at least ______ above the baseline and must last at least ________. -
ANS-10 bpm above the baseline and the acceleration must last at least 10 seconds
FHR variability can be interpreted with an external monitor - ANS-using a Doppler
technology called autocorrelation
As the history of EFM continues to unfold, one thing is certain: research continues to be
needed to identify best practices for EFM or IA in laboring women. Technology alone will
never be the answer. Standardization of terminology, multidisciplinary education
regarding FHR interpretation and underlying physiology, and management based on
collaboration and teamwork remain the best approach to safe passage for mother and
child, regardless of the technology employed.
True/False - ANS-true
Fetal oxygenation consists of two basic elements: the fetal response to interruption of
oxygen & transfer of oxygen from the environment to the fetus
True/False - ANS-true
Three anatomic shunts _________, _________ & _________ permit fetal blood to
bypass the liver and the lungs - ANS-ductus venosus, ductus arteriosus and foramen
ovale
Vasa previa is a placental vessel that traverses the chorioamniotic membrane in close
proximity to the cervical os
True/False - ANS-true
Name 3 causes of interrupted transfer of oxygen from the environment to the fetus -
ANS-lungs, heart, vasculasture, uterus, placenta, umbilical cord
Accumulation of lactic acid in the tissues results in metabolic acidosis. lactic acid
accumulation can lead to utilization of buffer bases (primarily bicarbonate) to help
stabilize tissue pH. If the buffering capacity is exceeded, the blood pH may begin to fall,
