**Question:** All are seen in DKA except -
**Correct Answer:** A. Hyperkalemia.
**Core Concept**
Diabetic ketoacidosis (DKA) is a serious complication of diabetes characterized by hyperglycemia, metabolic acidosis, and ketosis. It occurs when the body produces high levels of ketones, acidic substances that can be toxic in large amounts.
**Why the Correct Answer is Right**
Hyperkalemia is not typically seen in DKA. In DKA, potassium levels are usually low (hypokalemia) due to several factors, including insulin deficiency, increased glucose levels, and the effect of catecholamines. Insulin promotes potassium uptake in cells, and the lack of insulin leads to increased potassium levels in the blood.
**Why Each Wrong Option is Incorrect**
* **Option B:** Metabolic acidosis is a hallmark of DKA, caused by the accumulation of ketones and lactate.
* **Option C:** Hyperglycemia is a key feature of DKA, resulting from insulin deficiency and impaired glucose uptake in cells.
**Clinical Pearl / High-Yield Fact**
In DKA, the presence of hyperkalemia should raise suspicion for other underlying conditions, such as renal failure or adrenal insufficiency.
**Correct Answer:** A. Hyperkalemia.
