正确答案:
2. to startle and awaken the fetus
解释 :
Fetal acoustic stimulation involves the use of an instrument that emits sound levels of approximately 80 dB at a frequency of 80 Hz. The sharp sound startles and awakens the fetus and is used with nonstress testing as a method to evaluate fetal well-being. A fetoscope or Doppler stethoscope is used to listen to the fetal heart rate. Nipple stimulation or intravenous oxytocin is used to stimulate contractions. Ultrasound testing is used to determine amniotic fluid volume.
