A woman at 38 weeks gestation is in labor. The labor has been uneventful, and the fetal heart tracings have been normal. Spontaneous rupture of membranes occurs; fetal heart rate drops to 90 beats per minute for four minutes and then resumes a normal pattern. The most likely etiology for this fetal heart rate change is
A. Abnormal fetal presentation
B. Impaired placental circulation
C. Possible cord compression - Answer>>> C. Possible cord compression
Which of the following is the primary neurotransmitter of the sympathetic branch of the autonomic nervous system?
A. Acetylcholine
B. Dopamine
C. Norepinephrine - Answer>>> C. Norepinephrine
The most prevalent risk factor associated with fetal death before the onset of labor is:
a. Low socioeconomic status
b. Fetal malpresentation
c. Uteroplacental insufficiency
d. Uterine anomalies - Answer>>> c. Uteroplacental insufficiency
T/F: Use of a fetoscope for intermittent auscultation of the fetal heart rate may be used to detect accelerations and decelerations from the baseline, and can clarify double-counting of half-counting of baseline rate. - Answer>>> True
An appropriate initial treatment for recurrent late decelerations with moderate variability during first stage labor is
A. Amnioinfusion
B. Maternal repositioning
C. Oxygen at 10L per nonrebreather face mask - Answer>>> B. Maternal repositioning
T/F: In the context of moderate variability, late decelerations are considered neurogenic in origin and are typically amenable to intrauterine resuscitation techniques directed towards maximizing uterine blood flow. - Answer>>> True
Which of the following conditions is not an indication for antepartum fetal surveillance?
a. Gestational hypertension
b. Diabetes in pregnancy
c. Fetus in breech presentation
d. Decreased fetal movement - Answer>>> c. Fetus in breech presentation
