Question

the most fundamental pathophysiology of diabetic ketoacidosis is which of the following?

too little insulin.
too much insulin.
too much sugar.
too little sugar.

Explanation:

Identify the core mechanism of DKA

Using the Diabetic Ketoacidosis Pathophysiology knowledge point

• Diabetic ketoacidosis (DKA) is a life-threatening complication primarily occurring in patients with Type 1 diabetes.
• The fundamental underlying cause of DKA is an absolute or relative deficiency of insulin (too little insulin).
• Without adequate insulin, cells cannot uptake glucose for energy, leading the body to break down fats for fuel, which produces acidic ketone bodies.

Evaluate the given options

• "Too little insulin": Directly matches the primary pathophysiological trigger of DKA.
• "Too much insulin": This would lead to hypoglycemia (low blood sugar), not DKA.
• "Too much sugar": While hyperglycemia is present in DKA, it is a consequence of the lack of insulin, not the fundamental pathophysiological trigger itself.
• "Too little sugar": This describes hypoglycemia.

Answer:

• Too little insulin. (Correct answer)
• Too much insulin.
• Too much sugar.
• Too little sugar.
