Nursing Interventions ( 6 Questions)
A nurse is screening a pregnant woman for gestational diabetes using an oral glucose tolerance test (OGTT).
The nurse should instruct the woman to do which of the following before the test?
Eating a high-carbohydrate meal the night before can raise the blood glucose level and affect the test results.
The oral glucose tolerance test (OGTT) requires fasting for about 8 hours before the test to get accurate results.
Caffeine and smoking can also affect the blood glucose level and interfere with the test results
Some medications can alter the blood glucose level and cause false-positive or false-negative results. The woman should consult her doctor about taking her usual medications before the test.
The correct answer is choice B. Drink water only for 8 hours before the test. This is because the oral glucose tolerance test (OGTT) requires fasting for about 8 hours before the test to get accurate results.
The woman should not eat or drink anything except water during this time.
Choice A is wrong because eating a high-carbohydrate meal the night before can raise the blood glucose level and affect the test results.
Choice C is wrong because caffeine and smoking can also affect the blood glucose level and interfere with the test results.
Choice D is wrong because some medications can alter the blood glucose level and cause false-positive or false-negative results. The woman should consult her doctor about taking her usual medications before the test.
Normal ranges for OGTT vary depending on the laboratory and the type of glucose solution used. Generally, a normal fasting blood glucose level is less than 100 mg/dL, a normal 1-hour level is less than 180 mg/dL, a normal 2-hour level is less than 155 mg/dL, and a normal 3-hour level is less than 140 mg/dL.
