Answer:
D) pH, 7.25; PaCO2 50 mm Hg
Explanation:
For respiratory acidosis confirmation by arterial blood gas values, there should be:
- pH value less than 7.35 <em>(it indicates the acidosis in body but there may be multiple sources of acidosis). </em>
- Partial carbon dioxide pressure greater than 45 mmHg<em> (it indicates that the acidosis source is respiratory)</em>
Therefore a person with values (pH, 7.25; PaCO2 50 mm Hg) would express respiratory acidosis.
The value (pH, 5.0; PaCO2 30 mm Hg) indicates the respiratory alkalosis condition.
