A 16-year-old female, a known diabetic, is found by her parents in her bedroom, confused and disoriented. Her skin is warm and dry, breath has a fruity odor, and respirations are deep and rapid (Kussmaul). Her blood glucose level is 480 mg/dL. What is the MOST likely underlying condition?
- ADiabetic Ketoacidosis (DKA)
- BHypoglycemia
- CInsulin shock
- DHyperosmolar Hyperglycemic State (HHS)
Show answer & explanationAnswer & explanation
Correct answer: A. Diabetic Ketoacidosis (DKA)
The classic presentation of a diabetic patient with confusion, warm/dry skin, fruity breath, Kussmaul respirations (deep and rapid), and a very high blood glucose (480 mg/dL) is indicative of Diabetic Ketoacidosis (DKA).
Why the other options are wrong
- B. Hypoglycemia would present with cool, clammy skin, and a low blood glucose level, not warm/dry skin, fruity breath, or Kussmaul respirations.
- C. Insulin shock is another term for severe hypoglycemia, which is inconsistent with the presented symptoms and high blood glucose.
- D. HHS typically occurs in older type 2 diabetics, involves extremely high glucose levels (>600 mg/dL), and causes severe dehydration but usually without Kussmaul respirations or fruity breath (no ketoacidosis).
Diabetic Ketoacidosis (DKA)
A serious complication of diabetes, primarily Type 1, occurring when the body produces high levels of blood acids called ketones. It is characterized by hyperglycemia, metabolic acidosis, and dehydration.
- Common in Type 1 diabetics, often triggered by infection or missed insulin.
- Symptoms include altered mental status, warm/dry skin, Kussmaul respirations, fruity breath.
- High blood glucose levels (>250 mg/dL) are present.
