The correct answer is choice A. “Perform self-monitoring of blood glucose using a glucometer.” This instruction will help the pregnant woman with gestational diabetes to monitor her blood glucose levels and adjust her insulin dosage accordingly. Self-monitoring of blood glucose is recommended at least four times a day for women with gestational diabetes.

Choice B is wrong because “Check blood glucose levels once a week.” is not frequent enough to ensure adequate glycemic control. Women with gestational diabetes need to check their blood glucose levels daily or more often.

Choice C is wrong because “Maintaining blood glucose levels within the recommended range is not necessary.” is false and dangerous. Maintaining blood glucose levels within the recommended range is essential to prevent maternal and fetal complications such as macrosomia, hypoglycemia, congenital anomalies, and preeclampsia.

Choice D is wrong because “Ignore symptoms of hypoglycemia and hyperglycemia.” is also false and dangerous.

Symptoms of hypoglycemia and hyperglycemia should not be ignored, but reported to the health care provider and treated promptly.

Hypoglycemia can cause maternal seizures, coma, and death. Hyperglycemia can cause fetal distress, stillbirth, and neonatal death.

The normal range for fasting blood glucose in pregnancy is 60 to 95 mg/dL. The normal range for postprandial blood glucose in pregnancy is 100 to 129 mg/dL.
