A 26-year-old multipara is at 26 weeks' gestation. Her previous births include two large-for-gestational-age babies and one unexplained stillbirth. The nurse suspects gestational diabetes
Which tests would the nurse anticipate as being most definitive in making a diagnosis? 1. A 50 g, 1-hour glucose screening test
2. A single fasting glucose level
3. A 100 g, 1-hour glucose tolerance test
4. A 100 g, 3-hour glucose tolerance test
4
Rationale
1. All women get the initial 50 g of glucose and a 1-hour screening.
2. A single fasting glucose level is not an adequate indicator of the glucose level in relation to food.
3. The 100 g 1-hour tolerance test is not an adequate indicator of the glucose level in relation to food.
4. A client with a history of LGA infants or gestational diabetes will be given the 100 g of glucose and the 3-hour glucose tolerance test.
