A nurse is reinforcing teaching with a client who is in her second trimester and has a new diagnosis of gestational diabetes. Which of the following statements by the client indicates a need for further teaching?

c. "I will reduce my exercise schedule to 3 days a week."

The client should not reduce her exercise schedule, as physical activity can help lower blood glucose levels and improve insulin sensitivity in gestational diabetes. The client should aim for at least 30 minutes of moderate-intensity exercise on most days of the week unless contraindicated by her provider. Exercise can also help prevent excessive weight gain, preeclampsia, and macrosomia in pregnancy.

The other statements are correct and do not indicate a need for further teaching.

The client should limit her carbohydrates to 50% of her daily caloric intake, as carbohydrates have the most impact on blood glucose levels. The client should also choose complex carbohydrates that are high in fiber and low in glycemic index, such as whole grains, fruits, and vegetables. The client should know that she is at increased risk of developing type 2 diabetes, as gestational diabetes is a risk factor for future diabetes mellitus. The client should undergo screening for diabetes 6 to 12 weeks after delivery and every 1 to 3 years thereafter. The client should also adopt lifestyle modifications such as a healthy diet, regular exercise, and weight management to prevent or delay the onset of type 2 diabetes.The client should take her glyburide daily with breakfast, as glyburide is an oral antidiabetic agent that can be used to treat gestational diabetes when diet and exercise are not enough to control blood glucose levels. Glyburide stimulates the pancreas to produce more insulin and lowers blood glucose levels. Glyburide should be taken with the first meal of the day to avoid hypoglycemia.

c. Excessive uterine enlargement

A hydatidiform mole is a type of gestational trophoblastic disease, where the placenta develops abnormally into a mass of cysts that resemble grape-like clusters. A hydatidiform mole can cause excessive uterine enlargement, as the uterus grows larger than expected for the gestational age. The nurse should measure the fundal height and compare it with the expected value based on the last menstrual period or ultrasound.

The other findings are not associated with a hydatidiform mole and may indicate other conditions.

Whitish vaginal discharge is not a sign of a hydatidiform mole, but it may be normal in pregnancy due to increased cervical mucus production. However, if the discharge is foul-smelling, yellow, green, or bloody, it may indicate an infection or a complication such as preterm labor or placental abruption.

Fetal heart rate irregularities are not a sign of a hydatidiform mole, but they may indicate fetal distress or congenital anomalies. A hydatidiform mole usually does not have a viable fetus, and fetal heart tones are absent or very faint. The nurse should use a Doppler device or a fetal monitor to assess the fetal heart rate and rhythm.

d. Rapidly dropping human chorionic gonadotropin (hCG) levels are not a sign of a hydatidiform mole, but they may indicate a spontaneous abortion or an ectopic pregnancy. A hydatidiform mole usually causes very high hCG levels, as the abnormal placental tissue secretes large amounts of this hormone. The nurse should perform a urine or blood test to measure the hCG levels and monitor them for chan
