Question 6 of 859
Pregnant women with diabetes often have problems related to the effectiveness of insulin in controlling their glucose levels during their second half of pregnancy.
The nurse teaches the client that this is due to:
    Correct Answer: D

    Pregnant women with diabetes often experience difficulty with insulin effectiveness during the second half of pregnancy due to increased levels of human placental lactogen. This hormone acts as an insulin antagonist, reducing the effectiveness of insulin, stimulating lipolysis, and increasing the circulation of free fatty acids. Consequently, glucose regulation becomes more challenging, necessitating closer monitoring and potential adjustments in diabetes management.

Question 7 of 859
Diabetes during pregnancy requires tight metabolic control of glucose levels to prevent perinatal mortality. When evaluating the pregnant client, the nurse knows the recommended serum glucose range during pregnancy is:
    Correct Answer: A

    The recommended range for serum glucose levels during pregnancy is between 70 mg/dL and 120 mg/dL to reduce the risk of perinatal mortality. Maintaining glucose levels within this range helps to minimize the risk of complications for both the mother and fetus. Levels above 120 mg/dL can increase the risk of complications such as macrosomia and neonatal hypoglycemia, while levels below 70 mg/dL can lead to maternal hypoglycemia, which can be dangerous for both the mother and the child.

Question 8 of 859
When assessing fetal heart rate status during labor, the monitor displays late decelerations with tachycardia and decreasing variability. What action should the nurse take?
    Correct Answer: D

    Late decelerations with tachycardia and decreasing variability in fetal heart rate are signs of fetal distress, suggesting that the fetus may not be getting adequate oxygen. This situation requires immediate intervention to prevent potential harm to the baby. The nurse should report these findings to the physician or midwife immediately so that appropriate actions can be taken, such as repositioning the mother, administering oxygen, increasing IV fluids, or preparing for potential emergency delivery.

Question 9 of 859
A client has been diagnosed as being preeclamptic. The physician orders magnesium sulfate. Magnesium sulfate (MgSO4) is used in the management of preeclampsia for:
    Correct Answer: A

    Magnesium sulfate (MgSO4) is primarily used in the management of preeclampsia to prevent seizures. Preeclampsia is a condition characterized by high blood pressure during pregnancy, which can lead to eclampsia, a severe complication involving seizures. MgSO4 acts as an anticonvulsant by depressing the central nervous system to reduce the risk of seizures. It is not typically used for the prevention of uterine contractions, sedation, or fetal lung protection.

Question 10 of 859
The predominant purpose of the first Apgar scoring of a newborn is to:
    Correct Answer: C

    The predominant purpose of the first Apgar scoring of a newborn is to evaluate the infant’s vital functions. The Apgar score, taken shortly after birth, assesses the newborn's breathing, heart rate, muscle tone, reflexes, and skin color to determine how well the baby is doing and whether immediate medical care is required.
