Fasting RBS value is 110-115 mg/dl is indicative of?

Appeared in: NORCET 5 Prelims - Sept 2023 (Shift-2)

Explanation

A fasting blood sugar level of 110-115 mg/dL falls into the category of Impaired Fasting Glucose (IFG).
IFG is also known as pre-diabetes, which indicates a higher-than-normal blood sugar level, but not high enough to be diagnosed as diabetes.
According to the American Diabetes Association (ADA) criteria, a fasting plasma glucose between 100 mg/dL and 125 mg/dL is defined as pre-diabetes.

Option A: A diagnosis of diabetes mellitus requires a fasting plasma glucose level of 126 mg/dL or higher on more than one occasion.
Option C: A normal fasting plasma glucose level is considered to be less than 100 mg/dL. The value of 110-115 mg/dL is above this threshold.
Option D: This is not a diagnostic category. Furthermore, the value of 110-115 mg/dL is not high enough to confirm diabetes; it only indicates an increased risk for developing it.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Interpretation of fasting blood glucose levels for diagnosing dysglycemia as background academic context rather than a clinical decision trigger.
Identifying pre-diabetes is crucial as it is a major risk factor for developing Type 2 diabetes and cardiovascular disease.
Nurses play a key role in educating patients with pre-diabetes about lifestyle modifications, including diet, exercise, and weight management, to delay or prevent the progression to diabetes.
What if? If the patient's fasting blood sugar was 130 mg/dL, it would meet the criteria for a provisional diagnosis of diabetes. The next step would be to repeat the test on a different day to confirm the diagnosis.

How to Approach the Question

First, identify the key clinical value provided in the question: a fasting blood sugar of 110-115 mg/dL.
Next, recall the standard diagnostic criteria for blood glucose levels.
Compare the given value to the established ranges for normal, pre-diabetes, and diabetes.
The range 110-115 mg/dL fits within the pre-diabetes category (100-125 mg/dL).
Eliminate the other options based on these criteria: 'Normal' is below 100 mg/dL, and 'Diabetes' is 126 mg/dL or higher.
