Which test would the nurse anticipate to be done to determine if preterm labor is present in a patient whose symptoms are questionable?

ANS: B
A fetal fibronectin test may be ordered to assess the presence of preterm labor in patients whose presenting symptoms are questionable so that early intervention (e.g., tocolytic therapy, corticosteroids, transport to a tertiary center) can be initiated when indicated. Sonograms determine the presence and viability of a fetus. Amniocentesis determines genetic problems in a fetus. Doppler determines circulation in the vascular system of the mother or the baby.
