Passing meds on time, doing routine AM care, having good charting and finishing ahead of time is not necessarily above the standard. You're meeting the standard there, you're doing what you're supposed to be doing. Although my hats off to you, four patients is quite a load.
Getting above standards or excellents requires a little more, but is usally situtational, such as talking down a combative patient, recognizing a critical situation and making a difference, helping out with other nurses patients, or going the extra mile with your patients in teaching, etc.
I think you should be very proud of yourself that you are meeting the standards of a good nurse, although "adequate" sounds like a put down it really isn't. I applaud you for striving to do better, that's an excellent attitude and I would give you high marks for that.
I am a generous too. I worked with a BSN student whom I assigned a bath to on her very first clinical. The patient gave me so much praise about her wonderful care, the backrub, etc., I put that in her eval. for the day. Nothing wrong with handing out a few excellents when deserved and to help boost confidence.
