Question
The nurse reviews the blood gas results of a client with atelectasis. The nurse analyzes the results and determines that the client is experiencing respiratory acidosis. Which result validates the nurse's findings?
Solution
Respiratory acidosis is a condition that occurs when the lungs can't remove enough of the carbon dioxide (CO2) produced by the body. As a result, body's fluids, especially the blood, become too acidic.
In the context of blood gas results, the nurse would look for the following indicators of respiratory acidosis:
-
Elevated arterial carbon dioxide levels (PaCO2): Normal PaCO2 levels are typically between 35 to 45 mm Hg. In respiratory acidosis, these levels would be higher than 45 mm Hg.
-
Lowered blood pH: Normal blood pH levels are between 7.35 to 7.45. In respiratory acidosis, the pH would be lower than 7.35, indicating that the blood is more acidic than it should be.
-
Normal or lowered bicarbonate (HCO3) levels: Normal bicarbonate levels are typically between 22 to 26 mEq/L. In respiratory acidosis, these levels could be normal or slightly lower than normal.
So, the nurse's findings of respiratory acidosis would be validated by blood gas results showing elevated PaCO2, lowered blood pH, and normal or slightly lowered bicarbonate levels.
