A male client abruptly sits up in bed, reports having difficulty breathing and has an arterial oxygen saturation of 88%. Which mode of oxygen delivery would most likely reverse the manifestations?

a. Non-rebreather mask
b. Simple mask
c. Face tent
d. Nasal cannula

A. Non breather mask

Explanation:

Fraction of Inspired oxygen is the term that refers to the volumetric portion of oxygen in any inhaled gas as a result of inhalation.

A non-rebreather mask is the most effective in this case. This is due to it being able to deliver quantities of the fraction of inspired oxygen (FIO2) as high as 100 percent thereby reversing the manifestations observed.

The other modes in the options such as simple mask, face tent and nasal cannula can not deliver such quantity. They usually deliver lower levels of the Fraction of Inspired Oxygen(FIO2).

having the certification could make the person more required to do a certain thing then another.this could also lead to different job offers or opportunities.
