Agnus expounds: FYI the hiarcheal order is RN then Paramedic then EMT.
Me: And FYI "hiarcheal" is usually written as hierarchical. Also, there are some who would argue the order should be MD--->God--->Midlevel practitioners (PA/NP/CRNA)--->RN---->LPN---->CNA.
There are also other branches from above God where you have Firefighters and everyone else below them. Another branch starts above God where you have Police Officers and, of course, everyone else below them (the Police and Firefighter brances are often in mortal combat for the elusive taxpayer dollar and have to align their forces in conjunction with political candidates who, of course, are above God but under the Devil.
Branches usually do not intersect as you have suggested. This may occur on a forum, such as this, when the debate over who should work in an ER (paramedic vs RN) and who should be the supervisor of the other's actions, but these are only "pseudo-branches" as they are often just the cogitations of "internet experts" who like to tell stories about their first hand experiences in dealing with the other brances. Thus, the RN vs paramedic battle is usually fought in the small minds of those who often have never worked both jobs, yet think they know all about the other because they spent a few hours in a firehouse or an ER.
Your command of grammar
is a challenge and I had difficulty trying to grasp your somewhat rambling ruminations.
As an RN I'm not impressed with your hypothetical argument of emergency care being "one narrow focus," since emergency medical conditions can be very broad based. Perhaps what you meant was the focus of the paramedics training is on the initial identification of life-threatening conditions and their treatment with stabilization until delivery to an Emergency Dept. You can argue that "definitive" care starts in the hospital, but if all you get are dead bodies...well...might as well call yourself the morgue.
As a paramedic, I'm very impressed with how poorly you make your argument which rings of jealousy from not being able to ride around in the big red trucks with the lights and sirens on. Listen, if you want I'll help you get your paramedic certificate and then you too can join us at the firehouse for a little BS session as we kick back in the La-Z-Boy recliners and eat ice cream...but don't think for a second you get to hold the remote control...
