Which client should be monitored closely and provided with immediate care based on oxygen saturation levels?

Monitoring a client with an oxygen saturation level of 85% is critical, as this indicates a significantly low level of oxygen in the blood. Normal oxygen saturation levels typically range from 95% to 100%, and anything below 90% is often considered a medical emergency, warranting immediate assessment and intervention. An oxygen saturation of 85% suggests that the client's tissues may not be receiving adequate oxygen, potentially leading to serious complications, such as hypoxemia or respiratory failure.

This level of saturation implies the need for immediate care, which may involve supplemental oxygen therapy, further diagnostic evaluation, and potential stabilization measures, such as positioning the client for optimal breathing or preparing for rapid intervention, depending on the underlying cause.

In contrast, a client with 95% oxygen saturation is in a normal range and does not require immediate care, while a respiratory rate of 12 breaths per minute is within the normal range, indicating neither hypoventilation nor respiratory distress. Mild dizziness alone may not be an immediate concern unless accompanied by more alarming symptoms or low oxygen saturation. Thus, close monitoring and prompt care are essential for the client with an 85% oxygen saturation.
