**Core Concept**
Acute pancreatitis is a clinical condition characterized by inflammation of the pancreas, leading to various systemic complications. The pathophysiology involves premature activation of digestive enzymes within the pancreatic tissue, resulting in autodigestion and necrosis.

**Why the Correct Answer is Right**
The correct answer is **C**. Acute pancreatitis primarily causes hyperglycemia due to the destruction of beta cells in the islets of Langerhans and the resulting impairment of insulin production. However, it can also cause hypoglycemia in the later stages, especially in those with significant pancreatic necrosis.

**Why Each Wrong Option is Incorrect**
**Option A:** Hyperkalemia is actually a common finding in acute pancreatitis due to the release of potassium from damaged cells and the resulting shift from the intracellular to the extracellular space.
**Option B:** Hyperlipidemia is a known complication of acute pancreatitis, often associated with the release of lipase and other enzymes that break down triglycerides.

**Clinical Pearl / High-Yield Fact**
A key clinical correlation to remember is that acute pancreatitis can be triggered by hypertriglyceridemia, especially in those with very high levels of triglycerides.

**Correct Answer: D. Hypoglycemia.**
