You are assessing a man with suspected hypothermia. the patient is conscious and alert, and is actively shivering. his respiratory rate is increased, but his breathing is unlabored, and the pulse oximeter reads 72%. the pulse oximetry reading is most likely:

the pulse oximetry reading is most likely secondary to decreased perfusion in the extremities.

The patient has no abnormality in breathing beside increased rate so there shouldn't be any issue in oxygen level. 

When your body exposed to cold, the body will respond by constricting peripheral blood vessel. By doing so the body will prevent further heat loss because the blood is not exposed to the cold extremities. But it will reduce blood perfusion in your extremity, therefore the oxygen level might be reduced.

Heyyy! drugs are not good for u. and u should know that! it can injure you or hurt u! drugs itself sounds dangerous! i'm pretty sure u heard many stories about the danger of drugs! even if u are addicted or just want to, pls don't do it! it's harmful even though maybe u don't realize it. until u realize it, it's going to be too late, and i don't want that to happen to u or to anyone. drugs shouldn't be your top priority, just think about it, why do u want to use drugs? u can do so many other things that can relive u, or things u like to do. i might not get what situation u are in, but drugs can't be the thing on your mind all the time, what if the ppl that cares about u gets hurt because, one day they get a call that u are in a hospital; injured or they can have a knock on there door telling them that u past away or something happened. it's not cool and upsetting, obviously i'm not someone who can force u to not do anything u want to do, but pls keep in mind, always think about the people who cares about u, and if u see a child younger than u by a lot, or just younger, u would tell them to not do drugs(maybe) if u do tell them that, u realize it's bad for them, which means u abounds do it either bc its bad. no matter the age, u shouldn't be doing stuff that would hurt u, bottom line is, i can't tell u what to do, u do u, but i'm younger than u, and just want to say pls don't get hurt.

Idont understand what youre askimg
