I have been a pediatric radiology nurse for 6 year. Depending on where you work, it can involve sedation (which is mostly what I do). There are some nurses that work in Interventional radiology which is more like OR procedures with sterile fields and handing instuments while using fluoroscopy or ultrasound. From a sedation standpoint, the nurse and physician do a presedation history and physical, I draw up the sedation drugs and start the IV, prepare the room with bag/mask/suction, participate with getting the child sedated and on the mri/ct scanner and monitor vs throughout the scan. I also recover the patient and then discharge them or return inpatients to their rooms. I like it because it's fast paced and always different. As with most units, we do get "frequent fliers" that you get to know well and grow close to. I would definitly reccommend it!!
