A client with a history of impaired glucose tolerance asks the nurse about the potential impact on her current pregnancy.

The nurse explains that impaired glucose tolerance increases the risk of developing:.

The correct answer is choice A. Nonstress test.A nonstress test is a screening tool that uses fetal heart rate patterns and accelerations as an indicator of fetal well-being.It is commonly performed for pregnant women who have gestational diabetes and are taking oral antidiabetic drugs to monitor the effects of the medication on the baby.

Choice B. Biophysical profile is wrong because it is an ultrasound assessment of the fetal status with an NST.It utilizes ultrasound with EFM to assess five variables: fetal breathing movements, fetal movement, fetal tone, amniotic fluid volume, and fetal heart rate.

Choice C.Amniocentesis is wrong because it is a diagnostic procedure where a needle is inserted through the abdominal wall into the uterine cavity to obtain amniotic fluid and commonly performed for genetic testing, neural tube defects, fetal lung maturity, and hemolytic disease in the fetus or intrauterine infection.

Choice D. Chorionic villus sampling (CVS) is wrong because it is a diagnostic procedure where a needle is inserted through the abdominal wall into the uterine cavity to obtain chorionic villi (placental tissue) and commonly performed for chromosomal, metabolic and DNA testing.It does not test for neural tube defects.

The correct answer is choice C. The woman had no episodes of hypoglycemia or hyperglycemia during pregnancy.

This outcome indicates that the interventions were successful in maintaining a normal blood glucose level for the woman and preventing complications for her and her baby.

Choice A is wrong because the recommended weight gain for a pregnant woman with gestational diabetes is 11.5 to 16 kg (25 to 35 lb).

Gaining less than 10 kg (22 lb) may indicate inadequate nutrition or poor glycemic control.

Choice B is wrong because the ideal birth weight for a baby of a woman with gestational diabetes is between 2.5 and 4 kg (5.5 and 8.8 lb).

A baby who weighs 3 kg (6.6 lb) at birth is within the normal range, but it does not necessarily reflect the effectiveness of the interventions.

Choice D is wrong because the woman’s blood glucose levels may or may not return to normal within six weeks after delivery.

Gestational diabetes usually resolves after giving birth, but some women may develop type 2 diabetes later in life.

Therefore, a postpartum glucose test is recommended to check the woman’s status.

Normal ranges for blood glucose levels during pregnancy are:

• Fasting: less than 95 mg/dL

• One hour after meals: less than 140 mg/dL

• Two hours after meals: less than 120 mg/dL
