A nurse is collecting data from a fetal monitor strip and recognizes late decelerations. Which of the following actions should the nurse expect to be taken at this time?

Choice A rationale Repositioning the client to a left lateral position aims to improve uteroplacental perfusion by alleviating compression of the inferior vena cava by the gravid uterus. This enhances venous return to the mother's heart, increasing cardiac output and ultimately improving blood flow and oxygen delivery to the placenta and fetus, which can resolve late decelerations caused by uteroplacental insufficiency. Choice B rationale Documenting findings is a crucial nursing responsibility, but it is not the immediate intervention for addressing late decelerations. Scientific principles dictate that physiological stabilization takes precedence over documentation when fetal well-being is compromised. Documentation would follow after initial interventions are implemented to improve the fetal status. Choice C rationale Adjusting fetal monitor sensors might be necessary if the tracing is poor quality, but it does not directly address the physiological cause of late decelerations. Late decelerations reflect uteroplacental insufficiency, not merely a monitoring artifact. Addressing the underlying physiological compromise is the priority before troubleshooting equipment. Choice D rationale Inserting a fetal scalp electrode provides a more accurate assessment of fetal heart rate by directly monitoring the fetus. However, this is an invasive procedure and is typically considered after initial conservative measures, such as maternal repositioning and oxygen administration, have been attempted without resolution of the late decelerations.
