Re: confuse about an NCLEX question.
I think that disagreements on this subject have to do with a difference in perspectives and training between EMS and nursing.
In prehospital care, we are taught that you can safely administer high-flow oxygen to any potentially hypoxemic patient without worrying about the hypoxic drive theory.
Here is a great article on COPD that supports that view:
http://www.emedicine.com/emerg/topic99.htm
Most of the research into the hypoxic drive theory indicates that, if high-flow oxygen can knock it out at all, it's a process that takes hours or days, far longer than typical EMS transports. But it makes sense that nurses would be trained to avoid high-flow oxygen in these patients, since they likely
are caring for them over hours or days.
Okay - now back to the question. If you have a patient with new-onset chest pain and difficulty breathing, I'm surprised that the answer would be to just monitor. With chest pain, you would anticipate orders (or a protocol) for a 12-lead EKG, ASA, nitro, and possibly other interventions.
