A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?

Conditions:

1. Placental abruption, the premature separation of the placenta from the uterine wall, can occur due to hypertension, which increases the risk of vascular damage and bleeding behind the placenta, leading to its separation.
2. Oligohydramnios, a condition characterized by a deficiency of amniotic fluid, is typically associated with decreased fetal urine production, renal abnormalities, or placental insufficiency. However, none of the findings listed in the scenario directly correlate with this condition.
3. Spontaneous abortion, also known as miscarriage, can occur due to various factors such as genetic abnormalities, hormonal imbalances, or maternal health conditions. However, none of the findings listed in the scenario directly correlate with this condition.
4. Chorioamnionitis is an infection of the fetal membranes and amniotic fluid. While maternal fever is often associated with chorioamnionitis, it is not a finding listed in the scenario. Additionally, the other findings do not directly correlate with this condition.
5. Placenta previa is a condition where the placenta partially or completely covers the cervix. This condition is not directly associated with the findings listed in the scenario.

Findings:

1. Hypertension is a risk factor for placental abruption due to increased vascular resistance, which can lead to vascular damage and placental separation.
2. Temperature elevation may indicate an infection, such as chorioamnionitis, which can increase the risk of placental abruption.
3. Hyperreflexia can be associated with conditions like preeclampsia, which is characterized by hypertension and can increase the risk of placental abruption.
4. Vomiting alone is not directly associated with an increased risk of placental abruption.
5. Fundal height measurement can provide information about fetal growth and gestational age but is not directly associated with an increased risk of placental abruption.

A: Changing the TPN bag and tubing every 24 hours is standard practice to prevent infection, so this action is appropriate.
B: Checking glucose levels every 6 hours is necessary because TPN can significantly affect blood glucose levels.
C: Gradually increasing the TPN rate is a standard procedure to monitor tolerance to the infusion.
D: This indicates a need for intervention. TPN lines should not be used for any other infusions to prevent contamination and interactions between the nutrition formula and medications.
