What is the expected action for respiratory alkalosis?

• A. Decrease ventilation rate
• B. Increase CO2 levels
• C. Increase HCO3 levels
• D. Administer oxygen

Answer: (A)

In cases of respiratory alkalosis, the body experiences a decrease in carbon dioxide (CO2) levels due to hyperventilation, which leads to an increase in blood pH. To correct this condition, the expected action is to decrease the ventilation rate. This reduction in ventilation allows CO2 levels to increase back to normal, helping to restore acid-base balance. By decreasing the ventilation rate, the body can retain CO2, which will ultimately lead to an increase in acidity (or a decrease in pH) and correct the alkalosis. It’s important to understand that the primary issue in respiratory alkalosis is the loss of CO2 through excessive breathing, so the corrective action should focus on reducing that ventilation. The other options are achievable outcomes or treatments in various contexts, but they do not directly address the underlying mechanism of respiratory alkalosis effectively. Increasing CO2 or bicarbonate levels is not the first line of corrective action but rather may be seen in metabolic responses or compensations. Administering oxygen may be necessary in cases of hypoxemia, but it doesn’t address the primary issue of CO2 loss leading to alkalosis.
