What is the normal range for potassium levels in the body?

The normal range for potassium levels in the body is crucial for maintaining various physiological functions, including nerve conduction, muscle contraction, and maintaining fluid balance. The correct answer indicates that the typical potassium levels in a healthy adult range from 3.5 to 5.0 milliequivalents per liter (mEq/L).

This range is widely accepted in clinical settings and represents the balance necessary for normal cellular function. Levels below this range can indicate hypokalemia, which can lead to muscle weakness, cramps, and arrhythmias, while levels above this range signify hyperkalemia, which can also be life-threatening and might lead to cardiac complications.

Understanding the normal potassium range is essential for healthcare professionals when assessing electrolyte imbalances in patients and implementing appropriate interventions.
