In a scenario where the arterial blood gas shows alkalosis, and decreased CO2, which intervention is indicated?

• A. Increase the ventilatory rate
• B. Administer sedatives
• C. Prescribe bronchodilators
• D. Consider mechanical ventilation

Answer: (A)

In a scenario where arterial blood gas analysis reveals alkalosis accompanied by decreased CO2 levels, the indicated intervention is to increase the ventilatory rate. This approach addresses the underlying issue of respiratory alkalosis, typically caused by hyperventilation, leading to a significant loss of carbon dioxide (CO2). By increasing the ventilatory rate, the patient can retain more CO2, which helps to restore the acid-base balance towards normal levels. This compensatory mechanism helps to decrease the elevated pH that characterizes alkalosis, stabilizing the patient's condition. The other interventions might not directly address the root cause of respiratory alkalosis. Administering sedatives could potentially decrease the respiratory drive, which could exacerbate the low CO2 levels. Prescribing bronchodilators is typically relevant for conditions like asthma or COPD, rather than directly addressing alkalosis. Considering mechanical ventilation may be appropriate in severe cases of respiratory failure but is not the first step when dealing with respiratory alkalosis alone. Thus, increasing the ventilatory rate is a targeted and effective intervention in this context.
