The baseline FHR is the average rate during a 10-minute segment.Changes in FHR are categorized as periodic or episodic.These patterns include both accelerations and decelerations.The labor nurse is evaluating the client's most recent 10-minute segment on the monitor strip and notes a late deceleration.Which is likely to have caused this change?

Late decelerations are almost always caused by uteroplacental insufficiency.Insufficiency is caused by uterine tachysystole,maternal hypotension,epidural or spinal anesthesia,IUGR,intraamniotic infection,or placental abruption.Spontaneous fetal movement,vaginal examination,fetal scalp stimulation,fetal reaction to external sounds,uterine contractions,fundal pressure,and abdominal palpation are all likely to cause accelerations of the FHR.Early decelerations are most often the result of fetal head compression and may be caused by uterine contractions,fundal pressure,vaginal examination,and the placement of an internal electrode.A variable deceleration is likely caused by umbilical cord compression,which may happen when the umbilical cord is around the baby's neck,arm,leg,or other body part or when a short cord,a knot in the cord,or a prolapsed cord is present.
