At the last vaginal exam, the client who is in the late first stage of labor was fully effaced, 8 cm dilated, vertex presentation, and station -1. Which observation would indicate that the fetus was in fetal distress?

  • A. The fetal heart rate slowly drops to 110 beats/min during strong contractions, recovering to 138 beats/min immediately afterward.
  • B. Fresh meconium is found on the examiner's gloved fingers after a vaginal exam, and the fetal monitor pattern remains essentially unchanged.
  • C. Fresh, thick meconium is passed with a small gush of liquid, and the fetal monitor shows late decelerations with a variable descending baseline.
  • D. The vaginal exam continues to reveal some old meconium staining, and the fetal monitor demonstrates a U-shaped pattern of deceleration during contractions, recovering to a baseline of 140 beats/min.
Correct Answer: C

Rationale: Meconium staining alone is not a sign of fetal distress. Meconium passage is a normal physiological function that is frequently noted with a fetus of more than 38 weeks' gestation. Fresh meconium, in combination with late decelerations and a variable descending baseline, is an ominous signal of fetal distress caused by fetal hypoxia. It is not unusual for the fetal heart rate to drop to less than the 140 to 160 beats/min range in late labor during contractions, and, in a healthy fetus, the fetal heart rate will recover between contractions. Old meconium staining may be the result of a prenatal trauma that is resolved.
