Answer:
0.5
Explanation:
The nurse must ensure that the FIO2 must not be greater than 0.5. This is because if the FIO2 is even slightly greater than than for as little as 16 to 24 hours, it can get really toxic and then diffusion of gas and surfactant activity will be reduced drastically. In ideal circumstances, the oxygen source is expected to be room air and within a range of FIO2 0.18 - 0.21.
It can happen with lung cancer but i dont think breast cancer though.
