Do not, for any reason, take out your cell phone
and look at it. I know some people say they use them to look up meds, but you can usually look up meds on the hospital's computer system, as well. I makes you look like you are texting friends or just wasting time and can be interpreted as unprofessional, especially by nurses who are not of the same generation as you.
Do not turn your back to the patient when charting on a computer in a patient's room. If you must do so, make sure you turn and look at them before you start talking to them. This was mentioned to us by our clinical instructor. Apparently some students were doing this and it made the patient feel he/she was being ignored.
If you do not work as an aide, really take this opportunity in clinicals to learn how to help a pt to the bathroom, change a bed and give a bath. You WILL have to help with these things at some point if you work as a nurse on a hospital unit. Also, if you are willing to help in these ways, you will be a better team player. (Don't assume you will be done with baths and toileting once you are an RN.)
