A nurse is analyzing several fetal heart rate patterns. The pattern that would be of most concern to the nurse would be:
1. Moderate long-term variability.
2. Early decelerations.
3. Late decelerations.
4. Accelerations.
3
Rationale:
1. Moderate long-term variability is a reassuring sign that the fetus is not suffering from cerebral asphyxia.
2. Early decelerations occur before the onset of the uterine contraction. Early deceleration is usually considered to be benign.
3. Late decelerations are caused by uteroplacental insufficiency. The late deceleration pattern is considered a nonreassuring sign.
4. Accelerations are thought to be a sign of fetal well-being.
