1. Remember you are a visitor in your clinical facility. Treat the RNs, CNAs, LPNs - treat everyone as your would want to be treated and/or as if your instructor was immediately over your shoulders. Realize you represent your school to the community (hallway, patients and family). Be on your best behavior. You NEVER know who you will be interviewing with for your first job as a new grad. It's a small world...
2. Introduce yourself to the nurse you are working with. And to the CNA. Discuss your plan for the day. Will you be assessing the patient? Will you be documenting your assessments? Will you be passing medications - if so what types of meds - PO only, PO and SQ - discuss the whole plan. What care will you be providing? Baths, helping to ambulate - make sure you discuss it and document appropriately (as permitted by your facility - in some of my clinicals we only had to have our instructor's co-signature, others required our instructor be right there with us while working on the documentation).
3. Introduce yourself to patients and their visitors. Protect/respect your patient's privacy - it is always best to ask a patient if you can speak to them about their care or medications in front of their visitors. And explain it as such - 'My name is (name), and I am a student nurse, I will be part of your care team today, my instructor (name) is also helping too. I see you have some company. Do you mind if we discuss the medications I have for you with your visitor present? I ask because I value your privacy.'
4. If you are assessing a patient or taking vitals for med administration - if anything is not normal for that patient (pt with a hx of HTN suddenly is hypotensive) - that may require some trouble shooting (check the cuff, check it manual instead of machine etc), your instructor needs to know and the facility's staff assigned to care for that patient needs to know.
