Questions and Answers
1. A transient decrease in cerebral blood flow (increase in cerebral
blood pres- sure) during a contraction may stimulate and may
cause .
ANS Bararecptors, early decelerations
2. What is not a type of supraventricular dysthymia?
ANS PVC,s
3. The maintains transmission of beat to beat
variability
ANS Parasym- pathetic nervous system
4. The allows relatively well oxygenated blood to enter
the fetal heart directly, bypassing the liver.
ANS Ductous venous
5. (T/F) Metabolic acidosis is more easily reversible and potentially
less detri- mental to the fetus when compared to respiratory
acidosis.
ANS False
,6. is defined as the energy releasing process of metabolism
ANS Catabolism
7. periodic accelerations can indicate all of the following except
A. Stimulation of fetal chemoreceptors
B. Tracing is maternal
C. Umbilical vein compression
ANS A. Stimulation of fetal chemoreceptors
8. All of the following are likely causes of prolonged decelerations
except
A. Uterine tachsystole
B. Maternal hypotension
C. Prolapsed cord
D. Maternal fever
ANS D Maternal fever
9. denotes the spontaneous, rhythmic depolarization of cardiac
cells.
ANS Auto- maticity
10. A
, s a contraction begins, partial umbilical cord compression causes
occlu- sions of the low-pressure vein and decrease return of blood to
the fetal heart rate, resulting in decreased CO, hypotension, and a
compensatory FHR .
ANS – Acceleration
11. the umbilical vein carries what?
ANS Oxygenated blood from the placenta to the fetus.
12. is the primary neurotransmitter of the parasympathetic
branch of the autonomic nervous system.
ANS Acetylcholine
13. 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
ANS Baroreceptors.
14. The FHR baseline reflects what physiological process?
ANS Both parasympathetic and sympathetic response *(intact central nervous system)*
15. EFM is an excellent test for determining
the presence or absence of neurological injury.
A. Definitive
