What can be life-threatening when a patient goes into a state of hyperglycemia?

• A. Sepsis
• B. Diabetic ketoacidosis
• C. Hypoglycemia
• D. Pneumonia

Answer: (B)

In cases of hyperglycemia, one of the most critical conditions that can develop is diabetic ketoacidosis (DKA). This occurs when the body becomes unable to use glucose for energy due to insufficient insulin levels, leading to the breakdown of fats for fuel. As fat breakdown occurs, ketones are produced, which can accumulate to dangerous levels in the blood, causing metabolic acidosis.

Symptoms of DKA include excessive thirst, frequent urination, nausea, abdominal pain, weakness, and altered mental status. The high levels of glucose and ketones in the bloodstream can lead to severe dehydration, electrolyte imbalances, and can ultimately result in coma or death if not promptly treated. This makes DKA a life-threatening complication often associated with uncontrolled diabetes and hyperglycemia.

Other options, while they may present risks in diabetic patients or those with altered glucose levels, do not specifically stem from hyperglycemia as directly and immediately as diabetic ketoacidosis does, making DKA the most relevant and pressing concern in a hyperglycemic state.
