__________ pressure is also known as the "Sellek maneuver" and is used to PREVENT
VOMITING AND ASPIRATION (helps with visualization, but this is not why we do it on pts at
risk for aspiration) - ......ANSWER........cricoid
__________ safety includes:
-Hazard elimination (get rid of the sharp - use glue/staples) -Engineering controls (ex. blunt
tip suture) -Work practice (ex. use a neutral zone) -Administrative (ex. policies with peer
reviews) -PPE (ex. requiring double gloving - first glove removes 75% of contaminate from
surface of sharp and second glove removes 75% of contaminate from sharp, so even if still
exposed, it's less contaminate) - ......ANSWER........sharps
