A nurse is assisting with the monitoring of a client who is in the first stage of labor, with an external fetal monitor in place and IV fluids infusing. Which of the following factors will cause variable decelerations in the fetal heart rate?

Choice A rationale :

Prepare for cesarean birth. The nurse should consider preparing for a cesarean birth as the client is at 39 weeks of gestation and has heavy vaginal bleeding. Heavy vaginal bleeding during pregnancy could indicate an emergency situation such as placental abruption or placenta previa, both of which can be life-threatening for the mother and the baby. In such cases, an emergency cesarean birth might be necessary to ensure the safety of both the client and the baby. Promptly preparing for the procedure will help expedite the process and prevent any delays in providing necessary medical care.

Choice B rationale

Initiate an IV infusion of magnesium sulfate. Magnesium sulfate is not indicated in this situation. Magnesium sulfate is commonly used in obstetrics, particularly in the management of preeclampsia and eclampsia to prevent seizures. However, the client's heavy vaginal bleeding suggests a different issue and magnesium sulfate would not address the underlying cause. Instead, the focus should be on identifying and managing the cause of the bleeding to ensure the best outcome for the client and the baby.

Choice C rationale

Administer antibiotics. Administering antibiotics is not the priority action in this scenario. Heavy vaginal bleeding in a pregnant client requires immediate attention to assess the cause and determine the appropriate course of action. While antibiotics may be necessary in some situations, they are not the first-line treatment for heavy vaginal bleeding during pregnancy. The nurse should focus on providing prompt and appropriate care to address the client's immediate needs.

Choice D rationale

Request the RN to perform a cervical examination. Performing a cervical examination may provide valuable information about the cause of the heavy vaginal bleeding. It can help determine if the bleeding is related to cervical changes, such as cervical dilation or effacement. The findings from the cervical examination, along with other assessments, will aid in making the most appropriate decisions regarding the client's care. However, it is not the only action that the nurse should take. In this critical situation, the nurse must prioritize immediate interventions to ensure the safety and well-being of the client and the baby.

Choice D rationale:

The nurse should state, "The purpose of this medication is to boost fetal lung maturity.”. The rationale behind this choice is that betamethasone is a corticosteroid medication commonly administered to women at risk of preterm delivery between 24 and 34 weeks of gestation. Its primary goal is to accelerate fetal lung maturation by promoting the production of surfactant, a substance that coats the lungs and prevents their collapse. By enhancing lung development, the medication helps reduce the risk of respiratory distress syndrome and other respiratory complications that premature infants might face. It does not directly impact fetal heart rate (Choice A), halt cervical dilation (Choice B), or stop preterm labor contractions (Choice C).

Choice A rationale:

The nurse should not state, "The purpose of this medication is to increase the fetal heart rate.”. Betamethasone does not affect the fetal heart rate, as it is primarily used to enhance lung maturity, as mentioned earlier. The incorrect statement may lead to confusion and misunderstanding of the medication's intended purpose.

Choice B rationale:

The nurse should not state, "The purpose of this medication is to halt cervical dilation.”. Betamethasone does not stop or halt cervical dilation. Its main action is on the fetal lungs to promote surfactant production. Cervical dilation is a natural process that occurs during labor and is not influenced by this medication.

Choice C rationale:

The nurse should not state, "The purpose of this medication is to stop preterm labor contractions.”. Betamethasone is not used to stop or prevent preterm labor contractions directly. Instead, its focus is on improving fetal lung maturity to enhance the baby's respiratory function once born prematurely.
