Final answer:
The normal blood glucose levels for hyperglycemic patients before meals and at bedtime should be maintained in the range of 60-90 mg/100 ml in a fasting state and can reach up to 140 mg/100 ml post-prandially. Managing these levels is crucial for diabetes care.
Step-by-step explanation:
Assessing blood glucose levels before meals and at bedtime is essential for managing hyperglycemia in diabetic patients. The normal blood glucose level for a fasting or post-absorptive state, which is 12-14 hours after a meal, should range between 60-90 mg/100 ml. However, with reduction methods used in some tests, a range of 80-120 mg/100 ml is considered normal. After meals, known as the post-prandial state, the blood glucose level should be between 100-140 mg/100 ml. In a random blood glucose test, levels can range between 100-180 mg/100 ml after meals. It's important to monitor these levels closely as part of diabetes management, using tools like the glucose tolerance test (GTT) if necessary to confirm diabetes in patients with borderline or ambiguous symptoms.
