A nurse is evaluating the blood glucose levels of a pregnant woman who has gestational diabetes after a glucose tolerance test.
Which of the following results indicates that the woman has impaired glucose tolerance?
Fasting blood glucose level of 95 mg/dL
One-hour blood glucose level of 185 mg/dL
Two-hour blood glucose level of 135 mg/dL
Three-hour blood glucose level of 105 mg/dL
The Correct Answer is B
The correct answer is choice B. One-hour blood glucose level of 185 mg/dL.
This indicates that the woman has impaired glucose tolerance, which is a risk factor for gestational diabetes. According to Mayo Clinic, a normal blood glucose level is lower than 140 mg/dL (7.8 mmol/L) after a glucose tolerance test.
A blood glucose level between 140 and 199 mg/dL (7.8 and 11 mmol/L) is considered impaired glucose tolerance,

Correct Answer is C
Explanation
The correct answer is choice C. The woman should report any vaginal discharge or itching to her doctor, as these could be signs of a yeast infection, which is more common in women with diabetes.Yeast infections can cause irritation and discomfort, and may increase the risk of preterm labor or urinary tract infections
Choice A is wrong because checking blood glucose levels four times a day is recommended during pregnancy, not after delivery.After delivery, the woman may need to check her blood glucose levels less often, depending on her doctor’s advice
Choice B is wrong because drinking juice or soda can raise blood glucose levels and worsen hyperglycemia.The woman should drink water or sugar-free beverages if she feels thirsty
Choice D is wrong because stopping insulin or oral medication after delivery can lead to uncontrolled blood glucose levels and complications.
The woman should follow her doctor’s instructions on how to adjust her medication after delivery.Some women may need to continue taking insulin or oral medication for a while, while others may be able to stop or switch to a different type of medication
Correct Answer is C
Explanation
The correct answer is choice C. Elevated urine specific gravity.
This is because hyperglycemia causes osmotic diuresis, which increases the concentration of solutes in the urine.
Urine specific gravity is a measure of the density of urine compared to water and reflects the amount of solutes in the urine.A normal range for urine specific gravity is 1.005 to 1.030.
Choice A is wrong because elevated serum ketones are a sign of ketoacidosis, which is a complication of diabetes mellitus type 1, not gestational diabetes.Ketoacidosis occurs when the body breaks down fat for energy due to insufficient insulin and produces ketones, which are acidic byproducts that can lower the blood pH.
Choice B is wrong because decreased serum osmolality indicates dilution of the blood, which can be caused by excessive fluid intake, diuretic use, or syndrome of inappropriate antidiuretic hormone (SIADH).
Serum osmolality is a measure of the concentration of solutes in the blood and reflects the balance between water and electrolytes.A normal range for serum osmolality is 275 to 295 mOsm/kg.
Choice D is wrong because decreased blood pH indicates acidosis, which can be caused by ketoacidosis, lactic acidosis, renal failure, or respiratory failure.
Blood pH is a measure of the acidity or alkalinity of the blood and reflects the balance between carbon dioxide and bicarbonate.A normal range for blood pH is 7.35 to 7.45.
