Verified step by step guidance

Understand the normal range for potassium levels in the blood, which is typically between 3.5 to 5.0 mEq/L (mmol/L). A level of 5.5 mEq/L indicates hyperkalemia, or elevated potassium levels.

Consider the conditions listed and how they affect potassium levels. Cushing's syndrome often leads to hypokalemia (low potassium levels) due to increased aldosterone, which promotes potassium excretion.

Evaluate the impact of chronic kidney disease on potassium levels. The kidneys are responsible for filtering and excreting excess potassium. In chronic kidney disease, the kidneys' ability to excrete potassium is impaired, leading to potential hyperkalemia.

Analyze the effect of loop diuretics on potassium levels. Loop diuretics increase the excretion of potassium, often leading to hypokalemia rather than hyperkalemia.

Consider the impact of excessive vomiting on potassium levels. Vomiting can lead to loss of potassium from the body, typically resulting in hypokalemia rather than hyperkalemia.
