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 B
Explanation
The correct answer is choice B. Preeclampsia.
Preeclampsia is a complication of pregnancy that is characterized by high blood pressure, proteinuria, and edema.It can result from uncontrolled blood sugar levels, as well as other risk factors such as obesity, hypertension, and previous large for gestational age (LGA) infant.
Preeclampsia can lead to serious complications for both the mother and the baby, such as eclampsia, HELLP syndrome, placental abruption, and intrauterine growth restriction.
Choice A. Placenta previa is wrong because it is a condition where the placenta covers the cervix partially or completely.It is not caused by uncontrolled blood sugar levels, but by factors such as previous cesarean section, multiple gestation, advanced maternal age, and smoking.
Choice C. Chorioamnionitis is wrong because it is an infection of the amniotic fluid and membranes that surround the fetus.
It is not caused by uncontrolled blood sugar levels, but by bacteria that ascend from the vagina or cervix into the uterus.It can cause fever, uterine tenderness, foul-smelling amniotic fluid, and fetal tachycardia.
Choice D. Abruptio placentae is wrong because it is a condition where the placenta separates from the uterine wall before delivery.It is not caused by uncontrolled blood sugar levels, but by factors such as trauma, hypertension, smoking, cocaine use, and previous history of abruption.
Correct Answer is C
Explanation
The correct answer is choice C. 185 mg/dL.According to the Mayo Clinic, a blood sugar level of 190 mg/dL or higher indicates gestational diabetes.A blood sugar level below 140 mg/dL is usually considered normal.
Therefore, a blood sugar level of 185 mg/dL is above the normal range and below the diagnostic threshold for gestational diabetes.
Choice A is wrong because 160 mg/dL is within the normal range for the glucose tolerance test.
Choice B is wrong because 175 mg/dL is also within the normal range for the glucose tolerance test.
Choice D is wrong because 200 mg/dL is above the diagnostic threshold for gestational diabetes.
