I have worked 3 1/2 years as a Med/Surg Pediatric nurse and am considering a position in Adult Cardiac Telemetry. Has anyone else made such a big change? With peds most issues are respiratory, so I know I will have to relearn cardiac and adult medications. However I am very excited about learning something new. I also think it will broaden my knowledge of nursing and be extremely beneficial in the informatics field. Has anyone else been successful at switching nursing specialties? If so, how long did it take before you felt confident again?
