Question: 1 / 595

What is the normal potassium range in the body?

2.5-3.5

3.5-5

The normal potassium range in the body is 3.5 to 5.0 mEq/L. Potassium is a crucial electrolyte that plays an essential role in various bodily functions, including maintaining fluid balance, conducting nerve impulses, and ensuring proper muscle function, notably affecting heart rhythms. This range is vital for healthy bodily operations, particularly in nerve and muscle function, where potassium helps facilitate cellular communication and contraction.

Values below 3.5 indicate hypokalemia, which can lead to muscle weakness, cramping, and irregular heart rhythms, while values above 5.0 reflect hyperkalemia, potentially resulting in dangerous cardiac complications. Maintaining potassium levels within this normal range is therefore critical for overall health and stability, which clearly supports the selection of the answer indicating the range of 3.5 to 5.
