Which value represents an abnormal adult oxygen saturation?

Which value represents an abnormal adult oxygen saturation?

• A. 96 percent
• B. 92 percent
• C. 97 percent
• D. 99 percent

Answer: (B)

Normal adult oxygen saturation on room air is typically in the mid to high 90s. Readings below that range indicate hypoxemia, which is abnormal. Among the given values, the reading that falls below the normal range is the lowest one, making it the abnormal saturation. The other readings stay within the expected normal range for a healthy adult. If you see a value that drops below the normal threshold, follow your protocol to reassess, verify the equipment, and provide appropriate oxygen therapy or further evaluation as indicated.
