A patient's blood gas shows a pH of 7.25. This indicates?

• A. Acidosis
• B. Alkalosis
• C. Normal acid-base balance
• D. Metabolic stability

Answer: (A)

A blood gas result showing a pH of 7.25 indicates acidosis because it falls below the normal reference range for arterial blood, which is typically between 7.35 and 7.45. When the pH is less than 7.35, the body is considered to be in a state of acidosis, which can occur due to an accumulation of acids or a loss of bicarbonate. Understanding the pH scale is crucial for interpreting acid-base balance; lower pH values indicate an increase in hydrogen ion concentration, which characterizes acidosis. In clinical practice, recognizing this abnormality is important as it can guide further diagnostic and treatment decisions for the patient.
