The fetal heart rate baseline increases 20 beats/minute after vibroacoustic stimulation. The best interpretation of this is that the fetus is showing:
a. A reassuring response.
b. Progressive acidosis.
c. Parasympathetic stimulation.
d. A worsening hypoxia.
A
The fetus with adequate reserve for the stress of labor will usually respond to vibroacoustic stimulation with a temporary increase in the fetal heart rate (FHR) baseline.
An increase in the FHR after stimulation is reassuring.
An increase in the FHR after stimulation is a reassuring pattern and does not indicate prob-lems with the parasympathetic nervous system.
An increase in the FHR with stimulation does not indicate hypoxia.
