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:
The deltoid muscle, while commonly used for IM injections in older children and adults, is not the preferred site for newborns due to their underdeveloped muscle mass in this area. Administering an injection in the deltoid could increase the risk of injury to the surrounding nerves and tissues in newborns.

Choice B reason:
The vastus lateralis muscle is the recommended site for IM injections in newborns. It is the preferred location because it is the largest muscle in the thigh and has sufficient mass to absorb the medication effectively. This muscle is located on the anterolateral aspect of the thigh and is considered the safest site with the least risk of damaging blood vessels, nerves, or bone.

Choice C reason:
The dorsogluteal muscle, located in the buttocks, was once a common site for IM injections. However, it is no longer recommended due to the high risk of injury to the sciatic nerve and significant blood vessels in the area. Additionally, the fat content in the buttocks can affect the absorption of the medication.

Choice D reason:
The ventrogluteal muscle, also located in the hip area, is another site for IM injections but is more suitable for older children and adults. For newborns, the vastus lateralis remains the preferred site due to easier access and less risk of complications.
