Hyperglycemia
Hypoglycemia
Hyperkalemia
The Correct Answer is B
A. Hypernatremia: Hypernatremia refers to high sodium levels, which are not directly related to impaired glucose metabolism.
B. Hyperglycemia: Aging reduces insulin sensitivity and pancreatic function, leading to higher blood glucose levels, or hyperglycemia, which is a risk factor for diabetes mellitus.
C. Hypoglycemia: Aging-related insulin resistance typically results in elevated glucose levels (hyperglycemia), not low blood sugar (hypoglycemia).
D. Hyperkalemia: Hyperkalemia is an excess of potassium in the blood, which is not directly linked to impaired glucose metabolism.
