what are the duties of the ER Rn?

Today I did shadowing with a RN in the Med-surg floor. Basically, we spent the whole day going room to room giving medication (usually thru IV), she also check weight on one patient and checked a bandage on another..... and then she went back and did documentation on a pc.
Would this be similar duties of an RN in an ER setting? I need to know so i can decide on getting into pta or rn program... thanks.
I think you'd be better served doing a web search on the topic. Since the ER deals with any and all problems that walk, are carried through, or left just outside the door, the answers to your question border on infinite.

Ditto above, I would be here all day if I detailed everything In a nutshell, administering meds (sometimes mixing my own drips), assisting the ER physician with laceration repairs and lumbar punctures, running a code, monitoring critically ill patients, splinting, and on and on. I love the ER, such a huge diversity...and you get to learn a little about everything.

Generally, they work triage or one person is assigned that role depending on hospital size, do focused histories and assessments based on the patient's chief complaint, chart (paper or electronic), and then keep doing that. Eventually, the doctor will see the patient, do an even more focused assessment, write an order for a med or procedure, the nurse will administer it or help do it, chart, and then send the patient on their way or arrange for admittance to a floor bed.

Start your own IV'sDraw your own blood plus any redraws from "hemolyzed" (read lost) specimensCollect U/A's and some cases either do you own dip stick or run the U/A as a POC test yourself.Check in the line ambulance patients waiting on a bedMove people out of you room so triage can bring back that "I gotta have a bed now" patientWalk grandma to the bathroomGet the drunk a lunch boxTell the Doc/PA you'll get that accucheck after walking grandma back to bed from BRDo your own EKG'sMix most of your own drugs cause it take's pharmacy 4 hours and 9 phone call reminders to mix a gram of RocephinCheck the restraints on the tweaker in the hallWake up the security guard that is supposed to be watching the tweakerGo out to the lobby/smoking area/parking lot to find the family for grandma cause now she's getting a little agitated. only to find they went home and didn't leave any contact infoWalk back in grandma's room just in time to see her vault over the side rails into the floor (grandma's do bounce)Finally find help to get her back in bedGo clean up the tweaker who decided to have a BM in his pants instead of letting somebody know he had to goHelp hold the 2 month old febrile seizure baby for his LP, IV start, draw blood and straight cath for the septic work upGet the gangbanger that got shot up by "some dude" while "I was just walking down the street" prepped for ORThe Helicopter crew just landed with the meth lab explosion guy that's a crispy critter get him squared away and to the burn unitFinally see one of the 4 techs assigned to your side of the ER and ask them to roll grandma over to CT scan to be told "I'm busy stocking the trauma rooms". Well, I've been in the trauma bay for the past 2hrs with the GSW and the Burn guy and haven't seen you in there doing any stocking. Just get told the helicopter is going out on a 5 car MVA with 3 red tagsAnd all this before midnightGood times

The physical tasks that you see are only half the job. The real skill comes with prioritization, assessing, and coordinating all the resources.

lckrn2p.. said it just about exactly right. Keep in mind, that while this is tedious and sometime a pain, I LOVE working ER and wouldn't trade it for anything in the world. If you get bored easliy or are ADHA, then ER is the place for you!
