Screening and Diagnosis
Screening and Diagnosis ( 6 Questions)
A nurse is providing education to a pregnant client about the screening test for gestational diabetes.
The nurse explains that the test involves measuring blood sugar levels at different time points.
Which of the following blood sugar level readings would confirm a diagnosis of gestational diabetes?
These blood sugar levels are within the normal ranges.
Only the fasting blood sugar level is slightly above the normal range, but not enough to confirm a diagnosis of gestational diabetes
These blood sugar levels exceed the normal ranges for a pregnant woman undergoing a screening test for gestational diabetes.
Only the 1 hour and 2 hours blood sugar levels are slightly above the normal ranges, but not enough to confirm a diagnosis of gestational diabetes
The correct answer is choice C. Fasting: 90 mg/dL, 1 hour: 185 mg/dL, 2 hours: 160 mg/dL.
This is because these blood sugar levels exceed the normal ranges for a pregnant woman undergoing a screening test for gestational diabetes.
The normal ranges are:
• Fasting: less than 95 mg/dL
• 1 hour: less than 180 mg/dL
• 2 hours: less than 155 mg/dL
Choice A is wrong because these blood sugar levels are within the normal ranges.
Choice B is wrong because only the fasting blood sugar level is slightly above the normal range, but not enough to confirm a diagnosis of gestational diabetes.
Choice D is wrong because only the 1 hour and 2 hours blood sugar levels are slightly above the normal ranges, but not enough to confirm a diagnosis of gestational diabetes.
