A nurse is caring for a client who is at 22 weeks of gestation and has been unable to control her gestational diabetes mellitus with diet and exercise.
Which of the following medications should the nurse anticipate a prescription from the provider for the client?
A Repaglinide
B Insulin
C Glipizide
D Acarbose
The correct answer and Explanation is :
The correct answer is B Insulin.
Gestational diabetes mellitus (GDM) is a condition that occurs during pregnancy when the body is unable to produce enough insulin to meet the increased needs during this time. While lifestyle modifications such as diet and exercise are the first-line treatments, some women may not achieve adequate glycemic control through these methods alone, necessitating pharmacological intervention.
Insulin is the preferred medication for managing gestational diabetes, especially when dietary changes and exercise do not suffice. It is safe for both the mother and the developing fetus. Unlike oral hypoglycemic agents, insulin does not cross the placenta and has a long history of use in pregnancy, making it a reliable option for managing blood glucose levels effectively.
The other options presented have limitations in the context of GDM:
- A Repaglinide: This is a short-acting insulin secretagogue that can cause hypoglycemia and is not typically recommended during pregnancy due to insufficient safety data.
- C Glipizide: This is an oral sulfonylurea that stimulates insulin release from the pancreas. Although it can be effective for type 2 diabetes, there is limited evidence on its safety during pregnancy, and it can potentially cross the placenta, raising concerns about fetal effects.
- D Acarbose: This medication works by inhibiting carbohydrate absorption in the intestine. While it is sometimes used for type 2 diabetes, its safety and efficacy during pregnancy are not well-established.
In conclusion, for a pregnant client with gestational diabetes who has not achieved glycemic control through diet and exercise, insulin is the most appropriate and safe pharmacological choice, allowing for effective management of blood glucose levels and minimizing risks to both the mother and fetus.
