Question

The nurse assesses a patient who is receiving oxygen using a partial rebreather facemask at a flow rate of 12 L/min. The nurse notes the patient's oxygen saturation level is 90%. What is the nurse's next action?

Answer 1

A nurse assessing a patient with oxygen saturation at 90% using a partial rebreather mask should check the mask's fit and function, reassess the patient for respiratory distress, and consider escalating care. Low oxygen saturation can indicate hypoxemia or hypoxia, requiring prompt attention to prevent complications.

Step-by-step explanation:

The question at hand pertains to a nursing intervention for a patient whose oxygen saturation is measured at 90%, despite receiving oxygen through a partial rebreather mask at 12 L/min. Given that normal pulse oximeter readings range from 95-100%, a reading of 90% indicates hypoxemia. It is crucial for the nurse to first ensure that the partial rebreather mask is positioned correctly and functioning properly. If the equipment is functioning correctly and the low oxygen saturation persists, the nurse should assess the patient for any signs of respiratory distress or hypoxia, and prepare to escalate care which may involve notifying a doctor or respiratory therapist for further evaluation and intervention.

Oxygen saturation levels can be crucial indicators of a patient's respiratory function and are typically measured using a pulse oximeter. When patients experience breathing difficulties or have conditions affecting their respiratory systems, supplemental oxygen may be provided. This can increase the rate of oxygen binding to hemoglobin, hence improving the oxygen saturation levels. An oxygen saturation level below the normal range may require immediate medical attention to prevent organ damage and other severe complications arising from oxygen deprivation.
