A nurse is caring for an asthmatic client who requires a low concentration of oxygen. Which delivery device should the nurse use in order to administer oxygen to the client?
face tent
nasal cannula
nonrebreather mask
simple mask
The Correct Answer is B
A. A face tent delivers oxygen but is typically used for clients who cannot tolerate masks and usually provides variable oxygen concentrations.
B. A nasal cannula is appropriate for delivering low concentrations of oxygen (typically 24% to 44%) and allows the client to eat, talk, and move more easily. It is commonly used for clients who need low-flow oxygen therapy, such as those with asthma.
C. A nonrebreather mask delivers high concentrations of oxygen (up to 100%) and is not suitable when only low oxygen concentrations are needed.
D. A simple mask delivers moderate oxygen concentrations (35% to 50%) and is generally used when higher oxygen levels are required than with a nasal cannula.
