Practice Question

A nurse is caring for a client in the emergency department (ED) who has high anxiety and shallow respirations at a rate of 30/min. Which of the following acid-base disturbances is the client most likely experiencing?

Answer Choices:

Correct Answer:

Respiratory alkalosis

Rationale:

😰Anxiety triggers rapid, shallow breathing that expels excess carbon dioxide.

🫁Hyperventilation lowers PaCO₂, which raises blood pH above normal.

⚖️The primary disturbance is a decrease in carbonic acid with minimal effect on bicarbonate.

💡Respiratory alkalosis is defined by elevated pH and reduced PaCO₂ due to excessive ventilation.

📌Core Message

Excessive ventilation from anxiety leads to respiratory alkalosis by decreasing CO₂ and increasing pH.
