Which class of non-insulin antidiabetic medication is generally contraindicated in pregnancy due to insufficient safety data?
Answer: GLP-1 receptor agonists
GLP-1 receptor agonists lack adequate human pregnancy safety data and are classified as contraindicated during pregnancy.
What is the primary mechanism by which pregnancy causes insulin resistance?
Answer: Secretion of placental hormones such as human placental lactogen
Human placental lactogen and other placental hormones directly antagonize insulin signaling, producing physiological insulin resistance that peaks in the third trimester.
At what postprandial time point is blood glucose monitoring typically recommended for women with GDM?
Answer: 1 hour after eating
Postprandial monitoring at 1 hour after meal start is preferred in GDM because 1-hour values correlate more strongly with macrosomia risk than 2-hour values.
Women with type 1 diabetes are at greatest risk for hypoglycemia during which phase of pregnancy?
Answer: Early first trimester due to nausea and increased insulin sensitivity
Early pregnancy is characterized by increased insulin sensitivity combined with nausea-related reduced food intake, significantly raising hypoglycemia risk in type 1 diabetes.
A diabetes educator counsels a woman with GDM about physical activity. Which statement is most accurate?
Answer: Walking after meals can meaningfully reduce postprandial glucose levels
Post-meal walking increases muscle glucose uptake and has been shown to significantly lower postprandial blood glucose in women with GDM.
Approximately what percentage of women with GDM achieve adequate glycemic control through lifestyle modification alone?
Answer: 70–85%
Approximately 70–85% of women with GDM can meet glucose targets with medical nutrition therapy and physical activity, without requiring pharmacotherapy.
What is the standard recommended frequency of daily blood glucose self-monitoring for a woman newly diagnosed with GDM?
Answer: Four times daily (fasting and after each main meal)
Standard GDM monitoring involves four checks per day—fasting and 1 hour after each of three main meals—to ensure targets are consistently met.
