A nurse is caring for a client who is in labor and has an external fetal monitor.The nurse observes late decelerations on the monitor strip and interprets them as indicating which of the following?

Choice A rationaleUmbilical cord compression is associated with variable decelerations, not late decelerations. The distinction lies in the timing of the decelerations, as umbilical cord compression causes abrupt drops in heart rate rather than gradual late drops after contractions.Choice B rationaleLate decelerations occur due to uteroplacental insufficiency, where the placenta fails to adequately supply oxygen to the fetus. This is a sign of fetal distress, often caused by conditions such as maternal hypotension or placental abruption, requiring prompt intervention.Choice C rationaleFetal head compression leads to early decelerations, which are benign and occur as the head is compressed during contractions. This contrasts with late decelerations, which are indicative of compromised fetal oxygenation.Choice D rationaleMaternal bradycardia does not cause late decelerations on the fetal monitor. Late decelerations are specifically related to uteroplacental insufficiency, not maternal cardiac conditions. .
