How much CNA work should an RN do on a med surg floor of a hospital? Where I work,nurses have 3 to 6 patients and are responsible for taking vitals,physical assessments,wound cares, med passes,starting and d/Cing iv's, foley's and ng tubes;CNA's are responsible for passing trays, taking patients to the bathroom,giving showers. I had a nurse tell me that she's "old school" and does everything an RN would do for her patients, plus assist with all adls and give all showers for her patients. What do you think is fair? Is it ok for an RN to take a break if the CNA is super busy?
