Understand the concept of arterial pH: Arterial pH is a measure of the hydrogen ion concentration in the blood, which determines its acidity or alkalinity. The normal range for arterial pH is typically between 7.35 and 7.45, with values below 7.35 indicating acidosis and values above 7.45 indicating alkalosis.
Define physiological acidosis: Physiological acidosis refers to a state where the arterial pH is lower than the normal range but still compatible with life. This typically occurs when the pH is between 7.00 and 7.35, as values below 7.00 are considered severe acidosis and may be life-threatening.
Analyze the options provided: Review each range given in the question and compare it to the definition of physiological acidosis. The range 7.00 to 7.35 fits the criteria for physiological acidosis, as it is below the normal range but not critically low.
Eliminate incorrect options: Exclude ranges that do not align with the definition of physiological acidosis. For example, 6.80 to 7.00 represents severe acidosis, while 7.35 to 7.45 is the normal range, and 7.45 to 7.60 represents alkalosis.
Select the correct answer: Based on the analysis, the range 7.00 to 7.35 is the correct answer for physiological acidosis.
