Which of the following represents the normal potassium range in the laboratory?

The normal potassium range in the laboratory is 3.5-5.0 mEq/L. Potassium is a crucial electrolyte in the body, playing a significant role in various physiological processes, including nerve conduction, muscle function, and maintaining fluid balance.

Values within this range indicate proper potassium levels that facilitate normal cellular functions and are essential for the proper functioning of the cardiovascular system. Levels below 3.5 mEq/L may indicate hypokalemia, which can lead to muscle weakness, cardiac arrhythmias, and other health issues. Conversely, levels above 5.0 mEq/L, known as hyperkalemia, can result in serious complications, including life-threatening heart rhythm disturbances.

Understanding the normal potassium range is vital for healthcare professionals, as it enables them to assess and manage patients effectively. This knowledge helps in the interpretation of laboratory results and informs treatment decisions when electrolyte imbalances are detected.
