Which combination of arterial blood gas (ABG) values confirms respiratory acidosis if a male client with Guillain-Barré syndrome develops respiratory acidosis as a result of reduced alveolar ventilation?

A. pH, 5.0; PaCO2 30 mm Hg
B. pH, 7.40; PaCO2 35 mm Hg
C. pH, 7.35; PaCO2 40 mm Hg
D. pH, 7.25; PaCO2 50 mm Hg

Respuesta :

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 (it indicates the acidosis in body but there may be multiple sources of acidosis).
  • Partial carbon dioxide pressure greater than 45 mmHg (it indicates that the acidosis source is respiratory)

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.
