Recurrent late decelerations with minimal variability indicate fetal hypoxia; intervene and notify the provider immediately.

Test yourself first: 5 questions
Question 1 of 5
A nurse is assessing a fetal monitor tracing and observes decelerations that begin after the peak of the contraction and return to baseline well after the contraction ends. How should the nurse interpret this pattern?
Answer: C. Late decelerations begin after the contraction peak and recover after the contraction ends, indicating uteroplacental insufficiency. They are nonreassuring and require intervention. Early decelerations mirror the contraction and reflect head compression; variable decelerations are abrupt and relate to cord compression; accelerations are reassuring.
Question 2 of 5
A nurse notes early decelerations on a laboring client's fetal monitor strip. What is the appropriate nursing action?
Answer: A. Early decelerations mirror the contraction and are caused by fetal head compression as the cervix dilates. They are benign and reassuring, requiring only continued monitoring and documentation, not intervention. Stopping oxytocin, repositioning, or preparing for emergency cesarean would be appropriate for nonreassuring patterns such as late or prolonged decelerations.
Question 3 of 5
A client receiving oxytocin for labor augmentation has contractions occurring every 90 seconds, each lasting 100 seconds, with the fetal heart rate showing late decelerations. What is the nurse's first action?
Answer: A. Tachysystole (contractions too frequent or prolonged) with late decelerations indicates the uterus is overstimulated and the fetus is compromised. The first action is to stop the oxytocin infusion. Repositioning, increasing the main-line IV fluids, and applying oxygen follow, but discontinuing the offending drug is the immediate priority.
Question 4 of 5
A nurse observes early decelerations on the fetal monitor of a client in active labor. Which statement correctly describes the cause of this pattern?
Answer: C. Early decelerations mirror the contraction and are caused by fetal head compression. They are considered benign and require no intervention.
Question 5 of 5
A laboring client at term has a fetal heart rate tracing showing recurrent late decelerations. Which action should the nurse take first?
Answer: B. Late decelerations indicate uteroplacental insufficiency. The first intrauterine resuscitation action is to reposition the client to a side-lying position to improve placental perfusion. Other measures such as stopping oxytocin, giving oxygen, and increasing IV fluids follow.
Keep the streak going with more questions like these, each with a full rationale.
What is fetal heart rate decelerations?
The normal baseline fetal heart rate is 110-160 bpm. Recognizing the pattern tells the nurse whether the fetus is tolerating labor or is in distress. Memory aid VEAL CHOP: Variable=Cord compression, Early=Head compression, Accelerations=OK, Late=Placental insufficiency.
Key points to remember
- Early decelerations mirror the contraction (onset and return with the contraction) and are caused by fetal head compression; they are benign.
- Late decelerations begin after the contraction peaks and return after it ends; they reflect uteroplacental insufficiency and are non-reassuring.
- Variable decelerations are abrupt, V- or U-shaped drops unrelated to contraction timing, caused by umbilical cord compression.
- Accelerations (a rise of 15 bpm for 15 seconds) indicate a well-oxygenated, healthy fetus and are reassuring.
- Loss of variability combined with late or prolonged decelerations is a sign of fetal hypoxia.
Nursing priorities
- For late or variable decelerations, reposition the mother (left side first, then right or knee-chest) to improve perfusion or relieve cord pressure.
- Apply oxygen at 10 L/min via non-rebreather mask (when indicated) to increase fetal oxygenation.
- Stop or decrease oxytocin if it is infusing to reduce uterine activity.
- Increase the IV fluid rate to improve maternal blood pressure and placental perfusion.
- Notify the provider for persistent late or variable decelerations and prepare for possible intervention.
Patient teaching
- Changing positions during labor helps the baby get more oxygen, so cooperate with repositioning.
- The monitor and frequent checks are normal ways to make sure the baby is tolerating labor.
- Tell the nurse right away if your water breaks, since cord problems can affect the heart rate.
Red flags: report now
- Recurrent late decelerations with minimal variability indicate fetal hypoxia; intervene and notify the provider immediately.
- Prolonged deceleration or bradycardia (under 110 bpm sustained) requires emergency intervention.
- If repositioning, oxygen, and stopping oxytocin do not correct the pattern, prepare for emergency cesarean birth.
- Do not ignore loss of fetal heart rate variability, which is an early marker of compromise.
