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. The nurse should anticipate a prescription from the provider for which of the following medications for the client?

Choice A reason: "I know I am at increased risk to develop type 2 diabetes." is a correct statement, because it indicates that the client understands the long-term implications of gestational diabetes. The client should be aware that gestational diabetes increases the risk of developing type 2 diabetes later in life, and that she should have regular screening and follow-up.

Choice B reason: "I will take my glyburide daily with breakfast." is a correct statement, because it indicates that the client understands the medication regimen for gestational diabetes. The client should take glyburide, a sulfonylurea that lowers blood glucose levels, as prescribed by the provider, and monitor her blood glucose levels before and after meals.

Choice C reason: "I will reduce my exercise schedule to 3 days a week." is an incorrect statement, because it indicates that the client does not understand the importance of physical activity for gestational diabetes. The client should exercise at least 30 minutes a day, 5 days a week, unless contraindicated by the provider. Exercise can help improve insulin sensitivity, lower blood glucose levels, and prevent excessive weight gain.

Choice D reason: "I should limit my carbohydrates to 50% of caloric intake." is a correct statement, because it indicates that the client understands the dietary guidelines for gestational diabetes. The client should consume a balanced diet that provides adequate but not excessive amounts of carbohydrates, protein, and fat, and that is consistent in carbohydrate intake throughout the day.

Choice A reason: Blunt force trauma is a possible risk factor for placental abruption, which is a condition where the placenta detaches from the uterine wall and causes bleeding, pain, and fetal distress. However, blunt force trauma is not the most common risk factor, as it accounts for only a small percentage of cases. The most common causes of blunt force trauma are motor vehicle accidents, falls, or domestic violence.

Choice B reason: Hypertension is the most common risk factor for placental abruption, as it affects about 50% of cases. Hypertension can cause vasospasm and reduced blood flow to the placenta, which can weaken the attachment and lead to separation. Hypertension can be chronic, gestational, or related to preeclampsia.

Choice C reason: Gestational diabetes mellitus is not a risk factor for placental abruption, but rather a condition where the client develops high blood sugar levels during pregnancy and can cause complications, such as macrosomia, polyhydramnios, or neonatal hypoglycemia. Gestational diabetes mellitus does not affect the placental attachment or function.

Choice D reason: Cigarette smoking is a risk factor for placental abruption, as it can cause vasoconstriction and reduced oxygen delivery to the placenta, which can impair its growth and development. However, cigarette smoking is not the most common risk factor, as it affects about 25% of cases.
