Explanation

A fasting blood glucose level of 110-115 mg/dL falls within the standard diagnostic range for pre-diabetes, which is 100-125 mg/dL.
This state is also known as Impaired Fasting Glucose (IFG), indicating that blood sugar is elevated above normal but not high enough for a diabetes diagnosis.
This value signifies an increased risk of developing type 2 diabetes in the future.
Early detection at this stage allows for preventive interventions to be implemented.

Option A: A diagnosis of diabetes mellitus requires a fasting plasma glucose level of 126 mg/dL or higher on more than one occasion. The value of 110-115 mg/dL is below this threshold.
Option C: Normal fasting plasma glucose is defined as a level below 100 mg/dL. The value of 110-115 mg/dL is clearly above the normal range.
Option D: This value does not confirm diabetes; it indicates a pre-diabetic state. Confirmation of diabetes requires higher values (≥126 mg/dL) or other diagnostic tests like HbA1c or an Oral Glucose Tolerance Test (OGTT).

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 pre-diabetes and diabetes as background academic context rather than a clinical decision trigger.
Identifying pre-diabetes is a critical nursing function. It allows the nurse to initiate patient education on lifestyle modifications, such as diet, exercise, and weight management, which can significantly delay or prevent the onset of type 2 diabetes.
Nurses play a key role in monitoring patients with pre-diabetes, scheduling follow-up tests, and reinforcing the importance of adherence to lifestyle changes.
What if? If the patient's value was 130 mg/dL and was confirmed by a second test, the diagnosis would change from pre-diabetes to diabetes mellitus. The nursing care plan would then expand to include management of a chronic disease, education on medication (if prescribed), self-monitoring of blood glucose, and prevention of long-term complications.

How to Approach the Question

First, identify the key clinical data provided in the question: the test type ('Fasting RBS') and the specific value ('110-115 mg/dl').
Next, recall the standard diagnostic criteria for fasting blood glucose levels as defined by major health organizations like the American Diabetes Association (ADA).
Compare the given value (110-115 mg/dl) to the established ranges: Normal (<100 mg/dl), Pre-diabetes (100-125 mg/dl), and Diabetes (≥126 mg/dl).
Determine which category the value falls into. In this case, it is squarely within the pre-diabetes range.
Select the option that correctly names this category.
Eliminate the other options by confirming they represent incorrect ranges for the given value.
