What is the normal range for bicarbonate (HCO3) levels?

• A. 18-22 mEq/L
• B. 22-26 mEq/L
• C. 26-30 mEq/L
• D. 30-34 mEq/L

Answer: (B)

Bicarbonate (HCO3) levels are an important part of evaluating a patient’s acid-base balance and are typically measured in milliequivalents per liter (mEq/L). The normal range for bicarbonate levels is indeed 22-26 mEq/L. This range reflects the body’s ability to maintain a proper pH balance by neutralizing acids and bases in the blood. Bicarbonate acts as a buffer, helping to regulate acid-base status. When bicarbonate levels fall below this range, it may indicate acidosis, a condition where the body becomes too acidic. Conversely, levels above the normal range can suggest alkalosis, where the body is too alkaline. Hence, the significance of maintaining bicarbonate within the standard range of 22-26 mEq/L is critical for optimal metabolic function and homeostasis.
