What is an appropriate intervention for a fetus showing late decelerations?

• A. Change maternal position, increase IV fluids, and administer oxygen
• B. Immediate delivery via emergency cesarean section
• C. Increase maternal caffeine intake to stimulate fetal activity
• D. Initiate continuous fetal heart rate monitoring

Answer: (A)

The intervention involving changing the maternal position, increasing intravenous fluids, and administering oxygen is appropriate for addressing late decelerations in fetal heart rate. Late decelerations are typically indicative of uteroplacental insufficiency, where the fetus may not be receiving adequate oxygen during contractions. By changing the maternal position, such as moving the mother to her side, blood flow to the placenta can improve, potentially alleviating the pressure on the umbilical cord and enhancing fetal oxygenation. Increasing intravenous fluids helps maintain maternal hydration and might improve placental perfusion. Administering oxygen to the mother further increases the oxygen supply that can be delivered to the fetus, which is particularly vital in situations where fetal distress is noted. The other options do not address the immediate concerns regarding fetal wellbeing in the same effective manner. Immediate delivery via emergency cesarean section is a possible intervention in critical cases, but it is generally a last resort after non-invasive measures have been attempted. Increasing maternal caffeine intake would not only be inappropriate but could also potentially exacerbate fetal distress. Initiating continuous fetal heart rate monitoring is important for ongoing assessment but does not provide a solution to the issue of late decelerations and fetal distress.
