A patient with Type 1 Diabetes Mellitus is admitted to the emergency department with deep, rapid breathing, abdominal pain, and confusion. Which of the following laboratory findings would most likely confirm a diagnosis of diabetic ketoacidosis (DKA)?

Blood glucose level of 140 mg/dL with low insulin levels.

Blood glucose level of 180 mg/dL with normal ketone levels.

Blood glucose level of 250 mg/dL with normal ketone levels.

Blood glucose level of 600 mg/dL with elevated ketone levels in blood and urine.

Answer and Explanation

The Correct Answer is D

A.   A blood glucose level of 140 mg/dL is too low for DKA, which typically involves hyperglycemia above 250 mg/dL.
B.   A blood glucose level of 180 mg/dL and normal ketone levels are inconsistent with DKA, as DKA involves both high glucose and elevated ketones.
C.   A blood glucose level of 250 mg/dL with normal ketone levels would not suggest DKA. Elevated ketones are a critical part of diagnosing DKA.
D.   A blood glucose level of 600 mg/dL with elevated ketone levels in blood and urine confirms DKA, a life-threatening complication of Type 1 diabetes.

A. Dextrose 10% in water B. 25% albumin C. Dextrose 5% in water D. Dextran 40

Correct Answer is C

B. 25% albumin is not appropriate for treating hypernatremia and is typically used for volume expansion in cases of shock or hypoalbuminemia.
C. Dextrose 5% in water is an isotonic solution that helps dilute sodium levels and correct hypernatremia gradually.
D. Dextran 40 is a volume-expanding agent, not suitable for treating hypernatremia.
