Hyperglycemia results in which of the following?

• A. Normal blood glucose
• B. High blood glucose
• C. Low blood glucose
• D. Ketosis

Answer: (B)

Hyperglycemia means elevated blood glucose. When glucose in the blood is high, the body responds with increased urination and thirst, and if levels rise above the kidney’s reabsorption capacity, glucose spills into the urine (glucosuria) driving osmotic diuresis. This state directly describes high blood glucose. The other terms refer to different situations: normal blood glucose is a normal range (euglycemia), low blood glucose is hypoglycemia, and ketosis is a metabolic state with elevated ketone bodies from fat breakdown, which can occur in certain insulin-deficient conditions but is not the definition of hyperglycemia.
