Questions and Answers
1. When peripheral chemoreceptors respond to decreased oxygen
and in- creased CO2 this leads to an increase in?
a. arterial blood pressure
b. cardiac output
c. fetal heart rate
ANS a. arterial BP
2. Maternal hypoventilation may cause fetal hypoxemia and
a. asphyxia
b. hypercarbia
c. uterine artery vasospasm
ANS a. asphyxia
3. Normal PCO2 and decreased HCO3 are consistent with
what type of acidemia?
a. metabolic
,b. mixed
c. respiratory
ANS a. metabolic
4. simple diffusion of substances across the placental barrier is
a. accomplished via a hydrostatic or osmotic gradient
b. dependent on assistance of a carrier molecule
c. passive & requires no energy
ANS c. passive and requires no energy
5. the progressive decrease in FHR baseline as gestation advances is
considered to be a result of maturation of the
a. cardiac electrical pathways
b. fetal circulatory system
c. parasympathetic nervous system
ANS c. parasympathetic nervous system
6. when late decels occurs in the presence of moderate variability.
This is most likely due to chemoreceptor mediated response to
transient?
a. hypotension
b. hypoxemia
c. umbilical cord compression
, ANS b. hypoxemia
7. When late decelerations occur due to fetal hypoxia the best way
to improve oxygenation is to provide maternal oxygen by
a. nasal cannula
b. nonrebreather mask
c. simple face mask
ANS b. nonrebreather mask
8. A woman in labor on oxytocin develops tachysystole but the
other EFM parameters are within normal limits. The next step
is to
a. continue to moniot
b. decrease the oxytocin
c. start intrauterine resuscitation measurements
ANS b. decrease the oxytocin
9. If a category II tracing with minimal variability and absent fetal
heart accel- erations does not improve after interventions, the
clinician should recognize that
a. immediate c/s is indicated
b. it should be considered indeterminate
