NCC EFM PRACTICEA transient decrease in cerebral blood flow (increased cerebral blood pressure)
during a contraction may stimulate _____ and may cause a(n) _____
A. Baroreceptors; early deceleration
B. Baroreceptors; late deceleration
C. Chemoreceptors; early deceleration - ANSWERS-A. Baroreceptors; early
deceleration
The primary physiologic goal of interventions for late decelerations is to
A. Decrease maternal oxygen consumption
B. Maximize placental blood flow
C. Maximize umbilical circulation - ANSWERS-B. Maximize placental blood flow
Which of the following is most responsible for producing FHR variability as the
fetus grows?
A. Maturation of the parasympathetic nervous system
B. Maturation of the sympathetic nervous system
C. Release of maternal prostaglandins - ANSWERS-A. Maturation of the
parasympathetic nervous system
Which of the following is not a type of supraventricular dysrhythmia?
A. Premature atrial contraction (PAC)
,B. Premature ventricular contraction (PVC)
C. Supraventricular tachycardia (SVT) - ANSWERS-B. Premature ventricular
contraction (PVC)
Which is the most common type of fetal dysrhythmia?
A. Premature atrial contraction (PAC)
B. Premature ventricular contraction (PVC)
C. Third-degree heart block - ANSWERS-A. Premature atrial contraction (PAC)
All of the following are traits of fetal supraventricular tachycardia (SVT), but which
is most problematic?
A. Decreases diastolic filling time
B. Dramatically increases oxygen consumption
C. Often leads to ventricular tachycardia (VT) - ANSWERS-C. Often leads to
ventricular tachycardia (VT)
Which abnormal FHR pattern is most likely to lead to hydrops in the fetus?
A. Marked variability
B. A premature ventricular contraction (PVC)
C. Supraventricular tachycardia (SVT) - ANSWERS-C. Supraventricular tachycardia
(SVT)
,Which of the following is an irregular FHR pattern associated with normal
conduction and rate?
A. Premature atrial contractions (PACs)
B. Sinus arrhythmias
C. Sinus tachycardias - ANSWERS-B. Sinus arrhythmias
Which of the following is one example of a fetal tachyarrhythmia?
A. Second-degree heart block, Type I
B. Atrial fibrillation
C. Premature atrial contraction (PAC) - ANSWERS-B. Atrial fibrillation
(T/F) Sinus bradycardias, sinus tachycardias, and sinus arrhythmias are all
associated with normal conduction (normal P-waves followed by narrow QRS
complexes). - ANSWERS-True
(T/F) An internal scalp electrode will detect the actual fetal ECG. - ANSWERS-True
(T/F) An internal scalp electrode can solely diagnose a fetal dysrhythmia. -
ANSWERS-False
_____ are patterns of abnormal FHR associated with variability in R-to-R intervals,
but with normal P-waves preceding normal QRS complexes.
A. Arrhythmias
, B. Complete heart blocks
C. Dysrhythmias - ANSWERS-A. Arrhythmias
_____ are abnormal FHR rhythms associated with disordered impulse formation,
conduction, or both.
A. Arrhythmias
B. Supraventricular tachycardias
C. Dysrhythmias - ANSWERS-C. Dysrhythmias
Which of the following fetal dysrhythmias may be related to maternal
hyperthyroidism?
A. Sinus tachycardia
B. Premature atrial contractions (PACs)
C. Third-degree heart block - ANSWERS-B. Premature atrial contractions (PACs)
With _____ premature ventricular contractions (PVCs), the baseline and
variability are obscured.
A. Idioventricular
B. Bigeminal
C. Trigeminal - ANSWERS-B. Bigeminal
With _____ premature ventricular contractions (PVCs), the upward spikes will be
slightly longer than the downward spikes.
