A nurse is caring for a client who experienced a vaginal birth 12 hours ago. The nurse recognizes the client is in the dependent, taking-in phase of maternal postpartum adjustment. Which of the following findings should the nurse expect during this phase?

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.

Choice A reason:
Methylergonovine is used postpartum to prevent or control uterine bleeding by causing the uterus to contract. A firm fundus upon palpation indicates that the uterus is contracting well, which helps to compress the blood vessels and prevent excessive bleeding. This is the expected outcome when methylergonovine is effective.

Choice B reason:
The absence of breast pain is not directly related to the effectiveness of methylergonovine. Breast pain or engorgement typically occurs when milk comes in a few days postpartum and is not influenced by uterotonic medications.

Choice C reason:
An increase in lochia, or postpartum vaginal discharge, is not an indicator of methylergonovine's effectiveness. Lochia will naturally change and decrease as the postpartum period progresses and is not directly affected by the medication.

Choice D reason:
An increase in blood pressure is not an expected effect of methylergonovine and could indicate a side effect or complication. Methylergonovine can cause hypertension as a side effect, so an increase in blood pressure would warrant further assessment rather than indicating effectiveness.
