Is it common practice to allow SN access to the pixis and not have to have the RN preceptor access the pixis?
When doing anything with any patient, I believe firmly in informing the patient and family, if present, whatever I am doing or preparing to do. This is on patients that are A&Ox4, x1, sedated, in a coma, palliative/hospice, or taking their last breath. You never know what they are able to hear, understand, retain etc. Just a thought.
I would also think about future practice, being a student or professional, and do not do anything without an order or verifying the order, even if the preceptor is telling you to do it. Ask to see the order, use the MAR and go through your patient's medication administration rights, every patient, every time.
I would also be careful on how you are relating your version of events, this is a public forum and could easily be found and read by someone at your school, someone who could be on your appeal committee and puts 2 and 2 together, just another thought.
