A 2-year-old child in respiratory distress has an order to keep the O2 saturation above 95%. When the saturation falls to 80%, what should be the initial action by the practical nurse?

A 2-year-old child in respiratory distress has an order to keep the O2 saturation above 95%. When the saturation falls to 80%, what should be the initial action by the practical nurse?

• A. Double-check the order with the physician.
• B. Administer additional oxygen.
• C. Arrange for arterial blood gases to confirm the reading.
• D. Perform a chest assessment.

Answer: (B)

When a child in respiratory distress has an oxygen saturation that drops to a severely low level, the priority is to restore oxygen delivery right away to prevent hypoxic injury. Administering additional oxygen directly increases the amount available to the lungs and circulatory system, quickly raising the blood’s oxygen saturation toward normal levels. This immediate intervention can stabilize the child while you continue to assess and address the underlying cause of distress. After starting oxygen, you’ll recheck the saturation to assess the response and ensure the device is functioning and properly applied. If the reading lags or remains low despite adequate oxygen delivery, you’d then pursue further evaluation (such as confirming readings and considering ABGs) and escalate care as needed. The key is to act to improve oxygenation first, then verify and evaluate the next steps.
