A nurse is reviewing the electronic fetal monitor (EFM) tracing of a client who is in labor and has a prolonged deceleration of the fetal heart rate to 90/min.
The nurse should recognize that this finding indicates which of the following?
Fetal hypoxia
Fetal head compression
Fetal sleep cycle
Fetal movement.
The Correct Answer is A
A prolonged deceleration of the fetal heart rate to 90/min indicates acute fetal hypoxia/acidosis, which is a decrease in the blood flow to the placenta that reduces the amount of oxygen and nutrients transferred to the fetus. Fetal pH drops at a rate of 0.01/min during the deceleration. Causes of acute hypoxia include low maternal blood pressure, dehydration, anemia, rapid uterine contractions, placental abruption, and fetal hypoxia.
