A nurse is preparing a pregnant woman for a glucose tolerance test to screen for gestational diabetes.
The nurse should instruct the woman to do which of the following before the test?
Eat a high-carbohydrate meal the night before
Drink water only for 8 hours before the test
Avoid caffeine and smoking for 12 hours before the test
Take her usual medications with a sip of water
The Correct Answer is B
The correct answer is choice B. Drink water only for 8 hours before the test. This is because the test measures how your body responds to sugar (glucose) and drinking water will not affect your blood sugar levels. The test involves drinking a sugary drink and having your blood drawn before and after to check how your body handles the glucose.
Choice A is wrong because eating a high-carbohydrate meal the night before will raise your blood sugar levels and may interfere with the test results.
Choice C is wrong because caffeine and smoking can also affect your blood sugar levels and should be avoided before the test.
Choice D is wrong because some medications can affect your blood sugar levels and should be discussed with your doctor before the test.
The normal range for blood sugar levels during the glucose tolerance test is below 140 mg/dL (7.8 mmol/L) at one hour after drinking the sugary drink. If your level is higher than that, you may have gestational diabetes and need further testing. Gestational diabetes is a condition that develops during pregnancy and can cause problems for you and your baby if not well managed.

Hyperglycemia means having high
Correct Answer is A
Explanation
The correct answer is choice A. The nurse should monitor the woman’s blood glucose levels every hour during labor.This is because labor is a stressful event that can increase the blood glucose levels and the risk of complications for both the mother and the baby.The goal is to maintain the maternal glucose between 4.0 and 6.0-7.0 mmol/L during labor.
Choice B is wrong because every two hours is too infrequent to detect and correct any fluctuations in blood glucose levels during labor.
Choice C is wrong because every four hours is even more infrequent and could lead to poor glucose control and adverse outcomes.
Choice D is wrong because every six hours is the least frequent and the most dangerous option for monitoring blood glucose levels during labor.
Normal ranges for blood glucose levels are 3.9 to 5.5 mmol/L for fasting or preprandial values, and less than 7.8 mmol/L for postprandial values.
