A 56-year-old client with pneumonia is in respiratory distress. The healthcare provider prescribes the client 90% oxygen. How should the nurse administer the oxygen?

a. Non rebreather mask with a flow rate of 10 L/min
b. Venturi mask with a flow rate of 14 L/min
c. Nasal cannula with a flow rate of 6 L/min
d. Simple face mask with a flow rate of 8 L/min


The correct answer is A

Rational

Non rebreather mask with a flow rate of 10 L/min delivers from 80% to 90% oxygen. Venturi mask with a flow rate of 14 L/min delivers 55% oxygen. Nasal cannula with a flow rate of 2 L/min delivers 28% oxygen. Simple face mask with a flow rate of 8 L/min delivers 60% oxygen.

i would like to know if you may know the correct answer to this question. i took a kaplan course and i did 1155+ practice questions and i took my exam for nclex-rn. I recognized some of the topic of my questions from my practice but they were worded differently and i had three types of priority questions repeat but two were med/surg, and the other was psych. i 'm really unsure of the results and i feel as though i should have answered more questions. please reply with some advice ... thank you
