Final answer:
A concerning abnormal Fasting Blood Sugar level for Dr. Bahjat would be 200 mg/dL, indicating a potential diagnosis of diabetes mellitus and an increased risk of hyperglycemia and glucosuria. Option number d is correct.
Step-by-step explanation:
An example of an abnormal Fasting Blood Sugar (FBS) level that would be concerning for a doctor, such as Dr. Bahjat, is d) 200 mg/dL. Normal fasting blood glucose is below 100 mg/dL. A level between 100 mg/dL and 125 mg/dL indicates pre-diabetes, and a level above 125 mg/dL is diagnostic for diabetes.
Therefore, a fasting blood glucose level of 200 mg/dL is significantly high and suggests poorly controlled blood glucose, potentially indicative of diabetes mellitus. Hyperglycemia, as mentioned, occurs when levels rise above 180 mg/dL, increasing the risk of glucosuria because this level exceeds the renal threshold for glucose.
