What Statement Indicates That an EMT Understands the Appropriate Use

What statement indicates that an EMT understands the appropriate use of supplemental oxygen regarding care of a stroke patient?

A) "In the short time that we provide care to a stroke patient, the benefits of high-concentration oxygen outweigh the risks."
B) "If positive pressure ventilation is required, it should be given with room air and not supplemental oxygen."
C) "Since stroke decreases oxygen delivery to the brain, high-concentration oxygen should always be geared toward achieving an SpO₂ as near to 100% as possible."
D) "Oxygen should be administered at a minimal amount, just enough to get the SpO₂ at or above 94%."
