What are the normal serum potassium levels?

• A. 2.5 to 3.0 mEq/L
• B. 3.5 to 5.0 mEq/L
• C. 5.5 to 6.0 mEq/L
• D. 4.0 to 4.5 mEq/L

Answer: (B)

Normal serum potassium levels are considered to be in the range of 3.5 to 5.0 mEq/L. This range is crucial for maintaining various physiological functions in the body, as potassium plays a vital role in muscle contraction, nerve function, and maintaining cellular function. Levels below 3.5 mEq/L indicate hypokalemia, which can lead to muscle weakness, cardiac arrhythmias, and other health issues. Conversely, levels above 5.0 mEq/L signal hyperkalemia, which can also result in serious complications, including life-threatening cardiac problems. Understanding the normal serum potassium range is essential for monitoring and managing electrolyte imbalances effectively.
