A nurse is assisting with the care of a client who is in labour and has an external electronic fetal monitor. The nurse observes that the fetal heart rate begins to decelerate after the contraction has started, with the lowest point of the deceleration occurring after the peak of the contraction. Which of the following actions should the nurse take first?

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 A rationale:

Painless, bright red vaginal bleeding at 36 weeks gestation is indicative of placenta previa. Placenta previa is a condition in which the placenta partially or completely covers the cervix, leading to bleeding as the cervix begins to efface and dilate. The bright red color of the blood is due to its fresh origin from the exposed placental vessels. This condition is painless because the bleeding occurs without uterine contractions.

Choice B rationale:

Preterm labor is not the correct answer in this scenario. Preterm labor refers to the onset of regular uterine contractions leading to cervical changes before 37 weeks of gestation. In this case, the key indicator is painless bleeding, which is not associated with uterine contractions.

Choice C rationale:

Threatened abortion is also not the correct answer. Threatened abortion is the term used when a pregnant woman experiences vaginal bleeding, but the cervix is closed, indicating that there is still a chance for the pregnancy to continue. However, the bleeding in placenta previa is unrelated to fetal viability and is specifically caused by the placental position.

Choice D rationale:

Abruptio placentae is not the correct answer either. Abruptio placentae, also known as placental abruption, is a condition where the placenta prematurely separates from the uterine wall before delivery. This can cause painful bleeding due to the blood being trapped between the placenta and uterine wall. In the given scenario, the bleeding is described as painless, which does not align with the characteristics of abruptio placentae.
