A nurse in a clinic is teaching the mother of a 4-month-old infant who has been breastfed. The mother plans to switch her infant to an iron-fortified formula. Which of the following should be included in the teaching?

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:
Monitoring the heart rate is important for any newborn, but it is not the priority intervention for an SGA newborn. SGA newborns are at risk for several complications, but abnormal heart rates are not a primary concern directly related to being small for gestational age.

Choice b reason:
While monitoring weight is a part of routine newborn care and important for tracking growth and development, it is not the most immediate concern for an SGA newborn. The priority is to address potential acute complications that can arise from being small for gestational age.

Choice c reason:
Monitoring axillary temperature is important for maintaining normothermia in newborns, especially those who are SGA, as they have less subcutaneous fat and are more prone to heat loss. However, the most critical and immediate risk for SGA newborns is hypoglycemia, making blood glucose monitoring a higher priority.

Choice d reason:
SGA newborns are at increased risk for hypoglycemia due to their decreased glycogen stores. Therefore, monitoring blood glucose levels is a priority intervention. Hypoglycemia can lead to serious complications such as seizures and brain injury if not promptly identified and treated. It is essential to monitor blood glucose levels frequently and intervene as necessary to maintain them within a normal range.
