Question

A male client is admitted with a severe asthma attack. For the last 3 hours he has experienced increased shortness of breath. His arterial blood gas results are: pH 7.22 PaCO2 55 mmHg; HCO3 25 mEq/L or mmol/L (SI). Which intervention should the nurse implement?

Answer 1

The acid-base imbalance is respiratory acidosis. Interventions to improve ventilation and oxygenation should be implemented by the nurse.

Step-by-step explanation:

The acid-base imbalance in this case can be classified as respiratory acidosis. The decreased pH (7.22) and increased PaCO2 (55 mmHg) indicate acidosis. The HCO3 level (25 mEq/L or mmol/L) within the normal range suggests that compensation has not yet occurred.

The nurse should implement interventions to improve the client's ventilation and oxygenation. This may include administering bronchodilators, providing supplemental oxygen therapy, and assisting the client with effective breathing techniques. Monitoring the client's respiratory status and vital signs closely is also essential.
