Renee is very nervous/anxious during clinical.  She is not functioning at the same level of her fellow students.  She does not take direction well from her instructor.  She is very defensive, comes up with multiple excuses and does not allow instructor to finish my statement.  I have explained several times that nothing I say at clinical is personal, it is my job to teach her and each clinical day I will be telling her something or correcting her, she replies \"oh no you won\'t\".  Again I explained yes I will, it is why we are here and it is my job to teach.  I have received numerous comments from patients, family members and staff re: her nervousness and lack of confidence. She does not ever seek out my help with questions or concerns.  12/22- observed her asking the cleaning lady around 10 a.m. How to use a shampoo cap for her patient, I confirmed what I saw with the cleaning lady and then questioned Renee, who did not even know she was the cleaning lady, further questioning ranee did not know who aide was or even her nurse was, at 10am.  I discussed my concerns with ranee at the time, reviewing that must meet nurse, get report first thing on floor in morning.  I also discussed my concerns with D Barush.  On 1/21, 8am, I was approached by floor nurse, Charlotte, asking if her student posted was absent today, I said no why, she replied she had not met her yet, doesn\'t know what she looks like and was concerned the student did not come and ask for any report.  I went to ranee to inform her what was said to me, she became nervous, made an excuse had to get her vital signs first and then stated that she did get report from her nurse, I went back to nurse to tell her what student told me and she gasped and said no she should never lie, she did not.  Later in morning student did apologize for her defensive behavior, never admitted to lying to my face, and wanted to start fresh, I told student i would accept her apology but her behavior from day 1 to present would be reflected on eval. I again discussed my concerns with D. Barush and that all would be reflected in mid eval.
