A nurse in the labor and delivery unit is caring for a client who is undergoing external fetal monitoring. The nurse notices that the fetal heart rate starts to decrease after a contraction begins, with the lowest rate occurring after the contraction's peak. What should be the nurse's first action?
Administer oxygen using a non-rebreather mask.
Increase the rate of maintenance IV infusion.
Elevate the client's legs.
Place the client in the lateral position.
The Correct Answer is D
Choice A reason:
Administering oxygen using a non-rebreather mask is a subsequent step if initial measures do not improve fetal heart rate decelerations. It can help increase the amount of oxygen available to the fetus. Oxygen administration is a supportive measure that can be used if there are signs of fetal distress. In the scenario described, where the fetal heart rate slows after the start of a contraction with the lowest rate occurring after the peak, it suggests late decelerations, which are often associated with uteroplacental insufficiency. Administering oxygen can help increase the fetal oxygen reserve and is a common intervention during labor when there are concerns about fetal well-being.
Choice B reason:
Increasing the rate of maintenance IV infusion is typically considered when there is a concern for maternal hypotension or dehydration, which may not be the immediate cause of the observed fetal heart rate pattern. Increasing the rate of an IV infusion can help improve maternal hydration and blood pressure, which in turn can enhance placental perfusion. However, this intervention is more indirect and may not provide the immediate response needed to address fetal heart rate decelerations. It is typically considered after more direct interventions, such as repositioning the mother, have been attempted.
Choice C reason:
Elevating the client's legs can help improve venous return to the heart, potentially increasing maternal cardiac output and blood flow to the placenta. While this can be beneficial, it is not the primary intervention for late decelerations. Repositioning the mother to improve uteroplacental circulation is generally the first step.
Choice D reason:
Placing the client in the lateral position is often the first action taken when late decelerations are observed. This position helps improve uteroplacental blood flow and can quickly address potential issues related to fetal oxygenation. This position helps to relieve pressure on the inferior vena cava and aorta, which can be compressed by the gravid uterus, especially in the supine position. Relieving this pressure helps to improve uteroplacental circulation and can quickly address the cause of late decelerations, which is often related to compromised blood flow to the placenta.

Correct Answer is D
Explanation
Choice A reason:
Administering oxygen via face mask is a common intervention for late decelerations; however, it is not the first-line action. Oxygen is given to improve fetal oxygenation, but repositioning the mother has a more immediate effect on improving uteroplacental blood flow and, consequently, fetal oxygenation12.
Choice B reason:
Increasing the infusion rate of IV fluid is an intervention used to expand maternal blood volume, which can improve placental perfusion. However, this is not the primary action to be taken when late decelerations are noted, as it may take time for the increased fluid to affect the uteroplacental circulation.
Choice C reason:
Elevating the client’s legs can help increase venous return to the heart, potentially improving uteroplacental circulation. Nonetheless, this is not the most immediate action to take for late decelerations, as it does not directly address the potential compression of the vena cava or aorta.
Choice D reason:
Positioning the client on her side, particularly the left side, is the priority nursing action for late decelerations. This position helps relieve pressure on the inferior vena cava, enhancing maternal cardiac output and increasing blood flow to the placenta, which can quickly improve fetal oxygenation and resolve late decelerations
Correct Answer is ["A","C","D"]
Explanation
Choice a) Reason: History of migraines
Women with a history of migraines may experience an improvement or worsening of their migraine symptoms during pregnancy. Hyperemesis gravidarum, a condition characterized by severe nausea and vomiting, can be associated with migraines due to hormonal changes, stress, or dehydration that pregnancy may exacerbate.
Choice b) Reason: History of gestational hypertension
Gestational hypertension typically develops after 20 weeks of gestation, so it would not be expected in a client at 8 weeks of gestation. Additionally, there is no direct correlation between gestational hypertension and hyperemesis gravidarum.
Choice c) Reason: Twin gestations
Twin or multiple gestations can increase the likelihood of hyperemesis gravidarum due to higher levels of hCG (human chorionic gonadotropin) and other pregnancy-related hormones. These elevated hormone levels are associated with more severe nausea and vomiting.
Choice d) Reason: Nulliparous
Nulliparity (having never given birth) is not directly associated with an increased risk of hyperemesis gravidarum. However, first-time pregnancies can be unpredictable, and the condition can occur regardless of parity.
Choice e) Reason: Oligohydramnios
Oligohydramnios refers to a decreased amount of amniotic fluid and is not typically associated with hyperemesis gravidarum. It is more commonly related to conditions affecting the placenta or fetal kidneys.
