What is the normal value for arterial pH?

  1. 7.20 to 7.30

  2. 7.35 to 7.45

  3. 7.45 to 7.50

  4. Greater than 7.50

The correct answer is: 7.35 to 7.45

The normal value for arterial pH is typically defined as ranging from 7.35 to 7.45. This range indicates a healthy balance of acids and bases in the bloodstream, which is crucial for various physiological processes in the body, including enzymatic reactions and cellular functions. When the pH falls below 7.35, it may indicate acidosis, while a pH above 7.45 may suggest alkalosis, both of which can have significant health implications. Understanding these normal values is essential in clinical settings for diagnosing and managing various medical conditions related to acid-base imbalances.
