How should you provide emergency oxygen as part of your care? a. Provide emergency oxygen using a non-rebreather mask with a high flow rate (between 10 and 15 LPM). b. Give emergency oxygen with a nasal cannula and a flow rate of 12 LPM. c. Provide ventilations with a bag-mask device. d. Check for a medical ID tag and have her take deep breaths of room air.
