What interventions should be taken if late decelerations are noted during FHR monitoring?

• A. Place the mother on her left side, assess for uterine tachysystole, and increase IV fluids
• B. Encourage the mother to walk around and change positions frequently
• C. Administer pain medication and monitor vitals every hour
• D. Perform a cesarean section immediately

Answer: (A)

When late decelerations are observed during fetal heart rate (FHR) monitoring, it's crucial to respond quickly to ensure the wellbeing of both the mother and the fetus. Late decelerations often suggest fetal hypoxia due to uteroplacental insufficiency, where the fetus does not receive adequate oxygen, typically linked to decreased blood flow during contractions. Placing the mother on her left side is the primary recommendation in this scenario. This positioning can improve venous return and increase uterine perfusion, potentially alleviating the cause of the late decelerations. Additionally, assessing for uterine tachysystole is essential, as excessive uterine contractions can contribute to fetal distress. Increasing IV fluids can help combat any maternal dehydration and improve blood volume, thereby enhancing placental blood flow to the fetus. Encouraging the mother to walk or frequently change positions is not advisable because movement may exacerbate the condition instead of improving it. Pain medication and hourly vital monitoring, while important in the overall care of a laboring patient, do not directly address the underlying issue of late decelerations. Performing a cesarean section is an option if the fetus remains distressed despite interventions, but it is not the immediate response to late decelerations.
