Week 9: Sherpath: Collaborative Care of Diabetes
Questions and Verified Answers
Which laboratory finding warrants a repeat test to confirm a diagnosis of diabetes?
A. Hemoglobin A1c (HgbA1c) of 6.0%
B. Fasting plasma glucose level of 90 mg/dL
C. Random blood glucose value of 250 mg/dL
D. Oral glucose tolerance test with 2-hour glucose level of 150 mg/dL Correct Answer: C. Random blood
glucose value of 250 mg/dL.
A random plasma glucose value ≥200 mg/dL may indicate diabetes, but if the patient has no symptoms,
the test must be repeated to confirm the diagnosis and rule out a false-positive result.
Which instruction should the nurse give to a patient who is scheduled for a fasting blood glucose test?
A. "Do not take your cardiac medications before the test."
B. "You will drink a glucose solution 2 hours before the test."
C. "Do not eat or drink anything for 8 hours before the test."
D. "Bring someone with you to drive you home after the test." Correct Answer: C. "Do not eat or drink
anything for 8 hours before the test."
A patient should not eat or drink anything for 8 hours before a fasting blood glucose test. Food and drink
can interfere with test results.
Which diagnostic test result will the nurse review to evaluate a patient's blood glucose control over an
extended period?
, A. Fasting blood glucose
B. Random blood glucose
C. Oral glucose tolerance test
D. Glycosylated hemoglobin (HgbA1c) Correct Answer: D. Glycosylated hemoglobin (HgbA1c).
A glycosylated hemoglobin (HgbA1c) value indicates blood glucose control over time (approximately 3
months) by measuring the percentage of glycosylated hemoglobin molecules.
Which dietary instruction should the nurse include when reviewing dietary needs with a patient newly
diagnosed with diabetes?
A. "Consume 45 to 60 grams of carbohydrates per meal."
B. "Fats should comprise 10% of your daily food intake."
C. "Ensure that 30% of daily food intake comes from protein."
D. "Men and women are allowed to consume up to two alcoholic beverages per day." Correct Answer: A.
"Consume 45 to 60 grams of carbohydrates per meal."
The patient with diabetes should be instructed to include 45 to 60 grams of carbohydrates in every meal
to maintain a well-balanced diet and prevent hypo- and hyperglycemia.
The patient with new-onset type 2 diabetes asks the nurse about ways to lose weight. Which instruction
should the nurse include in patient education?
A. Use portion control.
B. Increase protein intake.
C. Begin a low-carbohydrate diet.
D. Eliminate all foods that are high in sugar. Correct Answer: A. Use portion control.
