EFM Certification Practice Questions with Expert
Solutions
A transient decrease in cerebral blood flow (increase in cerebral blood pressure) during a contraction
may stimulate _____ and may cause ____. - Answer Bararecptors, early decelerations
What is not a type of supraventricular dysthymia? - Answer PVC, s
The _____ _____ ______ maintains transmission of beat-to-beat variability - Answer Parasympathetic
nervous system
The _____ ______ allows relatively well oxygenated blood to enter the fetal heart directly, bypassing the
liver. - Answer Ductous venous
(T/F) Metabolic acidosis is more easily reversible and potentially less detrimental to the fetus when
compared to respiratory acidosis. - Answer False
_____ is defined as the energy releasing process of metabolism - Answer Catabolism
periodic accelerations can indicate all of the following except:
A. Stimulation of fetal chemoreceptors
B. Tracing is maternal
C. Umbilical vein compression - Answer A. Stimulation of fetal chemoreceptors
All of the following are likely causes of prolonged decelerations except:
A. Uterine tachsystole
B. Maternal hypotension
C. Prolapsed cord
D. Maternal fever - Answer D Maternal fever
, ____ denotes the spontaneous, rhythmic depolarization of cardiac cells. - Answer Automaticity
As a contraction begins, partial umbilical cord compression causes occlusions of the low-pressure vein
and decrease return of blood to the fetal heart rate, resulting in decreased CO, hypotension, and a
compensatory FHR ____. - Answer Acceleration
the umbilical vein carries what? - Answer Oxygenated blood from the placenta to the fetus.
_______ is the primary neurotransmitter of the parasympathetic branch of the autonomic nervous
system. - Answer Acetylcholine
_____ respond to increases in fetal arterial bp by detecting the amount of stretch and sending impulses
via the vagus nerve to the midbrain, decreasing FHR, CO, and BP - Answer Baroreceptors.
The FHR baseline reflects what physiological process? - Answer Both parasympathetic and sympathetic
response *(intact central nervous system)*
EFM is an excellent _____ test for determining the presence or absence of neurological injury.
A. Definitive
B. Diagnostic
C. Screening - Answer Screening
The normal mean value range for arterial bicarbonate (HCO3) is: - Answer 22-24
_____ FHR patterns are those associated with uterine contractions - Answer Periodic
The parasympathetic branch of the autonomic nervous system does what? - Answer Decreases FHR
T/F Fetal hemoglobin is higher than maternal hemoglobin. - Answer True
