Work in a hospital, not a nurse. Usually nurses bring meds with water and hand then to the pt. They either check on the lines, pumps, etc or chart for a minute or two. Then ask if there’s anything they need. By then they usually have taken the meds and the RN leaves. There’s only so many times you can tell a pt why they need to take them. I work with psychiatric pts and usually, if they refuse the RN just notes that they refused.
