The nurse providing care for the laboring woman should understand that late fetal heart rate (FHR) decelerations are the result of:
a. Altered cerebral blood flow. c. Uteroplacental insufficiency.
b. Umbilical cord compression. d. Meconium fluid.
ANS: C
Uteroplacental insufficiency would result in late decelerations in the FHR. Altered fetal cerebral blood flow would result in early decelerations in the FHR. Umbilical cord compression would result in variable decelerations in the FHR. Meconium-stained fluid may or may not produce changes in the fetal heart rate, depending on the gestational age of the fetus and whether other causative factors associated with fetal distress are present.
