A client has a fasting blood glucose of 112 mg/dL. How should the nurse interpret this result?

Correct answer

Prediabetes range — normal fasting glucose is 70-99 mg/dL; 100-125 mg/dL indicates prediabetes; this result warrants counseling on lifestyle modifications to prevent progression to type 2 diabetes

  1. A Normal — no follow-up needed
  2. B Prediabetes range — normal fasting glucose is 70-99 mg/dL; 100-125 mg/dL indicates prediabetes; this result warrants counseling on lifestyle modifications to prevent progression to type 2 diabetes
  3. C Type 2 diabetes diagnosis
  4. D Hypoglycemia

Why this is the answer

FASTING GLUCOSE INTERPRETATION: Normal: 70-99 mg/dL; Prediabetes: 100-125 mg/dL (impaired fasting glucose); Diabetes: 126 mg/dL or above on two separate occasions. The client's 112 mg/dL falls squarely in the PREDIABETES range. NURSING IMPLICATIONS: Education on lifestyle modifications: 5-7% weight loss if overweight; 150 minutes/week moderate-intensity aerobic exercise; reduced intake of refined carbohydrates, saturated fats, and processed foods; the Diabetes Prevention Program (DPP) showed that lifestyle intervention reduced progression to diabetes by 58% in high-risk individuals; consider referral to a structured lifestyle program; repeat HbA1c or fasting glucose in 1 year.
