In which condition would you expect to see elevated potassium levels?

Elevated potassium levels are commonly associated with acute kidney injury or renal failure. In these conditions, the kidneys are unable to effectively filter and excrete potassium from the body. Potassium is a vital electrolyte that helps regulate various physiological processes, including muscle function and cardiac rhythm. When renal function decreases due to injury or failure, potassium can accumulate in the bloodstream, leading to hyperkalemia, which can have serious cardiac implications.

In contrast, chronic liver disease might lead to various electrolyte imbalances, but elevated potassium levels are not a typical direct outcome. Dehydration due to excessive sweating usually results in low potassium levels (hypokalemia) since potassium is lost in sweat. Hyperthyroidism can lead to various metabolic changes, but elevated potassium is not a characteristic feature. Hence, acute kidney injury or renal failure is the most relevant condition linked to elevated potassium levels.
