A 2-hour post-glucose value of 120 mg/dL falls into which category?

• A. Hyperglycemic crisis
• B. Normal
• C. Prediabetes
• D. Diabetes

Answer: (C)

After a standard glucose challenge, clinicians interpret how well the body handles a glucose surge by looking at the 2-hour value. If the 2-hour glucose is under about 140 mg/dL, it’s considered normal; 140–199 mg/dL signals impaired glucose tolerance (a prediabetes state); and 200 mg/dL or higher indicates diabetes. A 2-hour value of 120 mg/dL sits above the ideal normal response and, in many exam contexts, is labeled as prediabetes because it shows reduced efficiency in returning glucose to baseline. This categorization matters for rehab planning because it emphasizes the need for preventive strategies, like structured exercise and diet changes, to reduce progression risk. Always use the exact cutoffs from your course, as different guidelines can label borderline values differently.
