ABG Pre Quiz

True or False:
Acid-base disorders involve imbalances in the body’s pH levels, often categorized as acidosis (low pH) or alkalosis (high pH). These disorders can be respiratory or metabolic in origin, and they are commonly identified through arterial blood gas (ABG) analysis.

• 40-50mmHg

When the opposite system is not responding, pH remains imbalances, this is ​ (a)   . ​
(b)   occurs when the opposite system is working to correct the imbalance, pH not yet normalized.
When homeostasis is achieved, all values have returned to normal, the blood gas is ​ (c)   .
