Just started at a SNF and today we got to shadow another nurse for about an hour. In that hour, I saw the nurse draw blood without gloves, give 3 injections without gloves, administer a higher dose of one of those injections than was ordered because "she felt like the patient needed it", check blood sugars without gloves, and not once wash/sanitize her hands in between patients. I am a brand new RN and want to learn as much as I can, but the safe and correct way! Can I please have your opinions on what to do with what I witnessed today and moving forward!? What I saw today really scares me!
