Answer: The patient's earlobe Q: What should the pulse oximetry reading be? Answer: 95% or higher Q: Why must a provider prescribe the flow rate & method of delivery of oxygen? Answer: Because oxygen is considered a medication Q: cannula Answer: A oxygen-delivery device consisting of a length of tubing with two small prongs for inserting into the nares Q: Safety guidelines during oxygen use include the following: Answer: ~ make sure there is adequate signage in the patient's room ~ avoid using electrical equipment ~ keep oxygen cylinders away from heat sources ~ make sure oxygen tubing has no kinks and is not a tripping hazard ~ know the location of fire extinguishers in your facility Q: What can oxygen cause?
