T/F: |Oxygen |exchange |in |the |placenta |takes |place |in |the |intervillous |space. |- |correct |answer-True



T/F: |The |parasympathetic |nervous |system |is |a |cardioaccelerator. |- |correct |answer-False



T/F: |Baroreceptors |are |stretch |receptors |which |respond |to |increases |or |decreases |in |blood |pressure. |-
|correct |answer-True




T/F: |There |are |two |electronic |fetal |monitoring |methods |of |obtaining |the |fetal |heart |rate: |the |
ultrasound |transducer |and |the |fetal |spiral |electrode. |- |correct |answer-True



T/F: |Variability |can |be |determined |with |the |fetoscope. |- |correct |answer-False



T/F: |Because |the |ultrasound |transducer |and |toco |transducer |are |sealed |units, |they |can |be |dipped |in |
warm |water |to |make |cleaning |easier. |- |correct |answer-False



T/F: |The |most |common |artifact |with |the |ultrasound |transducer |system |for |fetal |heart |rate |is |
increased |variability. |- |correct |answer-True



T/F: |All |fetal |monitors |contain |a |logic |system |designed |to |reject |artifact. |- |correct |answer-True



T/F: |The |monitor |should |always |be |tested |before |starting |a |tracing, |either |external |or |internal |mode |
and |labeled |a |test. |- |correct |answer-True

,T/F: |The |paper |speed |on |the |fetal |monitor |should |always |be |set |at |1cm/min. |- |correct |answer-False



T/F: |Both |internal |and |external |monitoring |methods |are |equally |accurate |means |of |obtaining |the |fetal
|heart |rate |and |contraction |patterns. |- |correct |answer-False




T/F: |The |external |toco |is |usually |placed |over |the |uterine |fundus |to |pick |up |contractions. |- |correct |
answer-True



T/F: |The |external |toco |gives |measurable |uterine |pressure. |- |correct |answer-False



T/F: |The |fetal |spiral |electrode |can |be |placed |when |vaginal |bleeding |of |unknown |origin |is |present. |- |
correct |answer-False



T/F: |The |ultrasound |transducer |is |usually |placed |on |the |side |of |the |uterus |over |the |baby's |back, |as |
the |fetal |heart |is |heard |best |there. |- |correct |answer-True



T/F: |The |spiral |electrode |is |used |to |more |accurately |determine |the |frequency, |duration, |and |intensity |
of |uterine |contractions. |- |correct |answer-False



T/F: |The |heart |rate |from |a |well-applied |fetal |spiral |electrode |can |only |be |fetal, |not |maternal. |- |correct
|answer-False




T/F: |The |intrauterine |catheter |is |used |to |pick |up |the |fetal |heart |rate. |- |correct |answer-False



T/F: |The |internal |spiral |electrode |may |pick |up |the |maternal |heart |rate |if |the |baby |has |died. |- |correct |
answer-True



T/F: |Fetal |arrhythmias |can |be |seen |on |both |internal |and |external |monitor |tracings. |- |correct |answer-
True

, T/F: |Variability |and |periodic |changes |can |be |detected |with |both |internal |and |external |monitoring. |- |
correct |answer-True



T/F: |Variable |decelerations |are |a |result |of |cord |compression. |- |correct |answer-True



T/F: |The |presence |of |FHR |accelerations |in |the |intrapartum |and |antepartum |periods |is |a |sign |of |
adequate |fetal |oxygenation. |- |correct |answer-True



T/F: |Variable |decelerations |are |a |vagal |response. |- |correct |answer-True



T/F: |Late |decelerations |have |a |gradual |decrease |in |FHR |(onset |to |nadir |30 |seconds) |and |are |delayed |
in |timing |with |the |nadir |of |the |deceleration |occurring |after |the |peak |of |the |contraction. |- |correct |
answer-True



T/F: |The |fetal |heart |rate |baseline |can |be |determined |during |periods |of |marked |variability. |- |correct |
