What is a key symptom to monitor for in a client experiencing respiratory alkalosis?

• A. Oxygen saturation below 90%
• B. Hypoventilation
• C. High carbon dioxide levels
• D. Decreased urinary output

Answer: (A)

In the context of respiratory alkalosis, one of the key symptoms to monitor for is oxygen saturation levels. Respiratory alkalosis is a condition that occurs when there is an excess of base or a deficiency of acid in the blood due to hyperventilation, which leads to decreased carbon dioxide levels. The physiological response of hyperventilation can initially lead to increased levels of oxygen in the blood.

However, as the condition progresses, it can affect the body's ability to adequately exchange gases, particularly if there is an underlying problem such as anxiety or pulmonary disease that may accompany respiratory alkalosis. In such cases, it is crucial to monitor the client's oxygen saturation. A saturation below 90% indicates insufficient oxygen supply, which requires immediate intervention.

While hypoventilation, high carbon dioxide levels, and decreased urinary output are important considerations in other contexts, they do not directly correlate with the defining characteristics of respiratory alkalosis, which primarily involves elevated pH and lowered carbon dioxide levels. Monitoring oxygen saturation provides a more direct assessment of the client's respiratory status and helps guide appropriate clinical actions.
