A nurse is caring for a client who is 4 hours postpartum following a vaginal birth. The client has saturated a perineal pad within 10 minutes. Which of the following actions should the nurse take first?

Choice a reason:
The viability of the fetus at 38 weeks of gestation is typically not the primary concern when heavy, red vaginal bleeding occurs without contractions. Fetal movements reported by the mother are a good sign of fetal well-being. However, the ultrasound in this scenario is more likely to be used to rule out placental issues that could cause bleeding, rather than to assess fetal viability.

Choice b reason:
The biparietal diameter (BPD) is a measurement taken during an ultrasound to assess fetal growth and development. While BPD is an important parameter, it is not typically the focus of an urgent ultrasound in the context of heavy vaginal bleeding late in pregnancy. The BPD is more relevant to growth assessments rather than acute bleeding episodes.

Choice c reason:
Locating the placenta is crucial in the case of heavy, red vaginal bleeding at 38 weeks of gestation. The bleeding could be indicative of placental abruption or placenta previa, both of which are serious conditions that require immediate medical attention. An ultrasound can quickly determine the location of the placenta and assess for these conditions.

Choice d reason:
Assessing fetal lung maturity is not typically the priority in an emergency situation involving heavy vaginal bleeding. While lung maturity is an important consideration for the timing of delivery, especially in preterm labor, the immediate concern in this scenario would be to identify the source of bleeding and ensure the safety of both the mother and fetus.

Choice A reason:
A blood glucose level of 96 mg/dL is within the normal range for a fasting blood sugar level in pregnancy, which is typically between 70 to 95 mg/dL. It is crucial to monitor blood glucose levels during pregnancy due to the risk of gestational diabetes, which can have adverse effects on both the mother and the fetus.

Choice B reason:
The production of estrogen is indeed enhanced during pregnancy. Estrogen plays a vital role in maintaining the pregnancy, promoting fetal development, and preparing the body for childbirth. Elevated levels of estrogen are expected and contribute to many of the physiological changes experienced during pregnancy.

Choice C reason:
A heart rate of 120 bpm (beats per minute) can be considered slightly elevated during pregnancy. The normal resting heart rate for a pregnant woman is usually between 60 to 100 bpm. However, during pregnancy, the heart rate can increase to accommodate the increased blood volume and the needs of the growing fetus. Given the information provided, the most likely scenario that the nurse should address is the heart rate of 120 bpm, as it is slightly above the normal range and may need monitoring or intervention.

Choice D reason:
Weakened respiratory contractions are not typically expected during pregnancy. Pregnant women may experience shortness of breath due to the growing uterus pushing against the diaphragm, but the respiratory contractions themselves should not be weakened. If this occurs, it may warrant further investigation.
