After meeting with Abby on November 7th, she verbalized an understanding of deficiencies in clinical.  On November 10, I spent the day with Abby passing medications on her 2 patients.  At our 10 am med pass, after discussing the actions of the medications as we were preparing them, Abby went to administer a beta blocker to her patient without assessing a blood pressure or heart rate.  I stopped her prior to administration so she could perform the appropriate nursing interventions.  She verbalized an understanding of the error.  At our noon med pass, while preparing to administer a calcium channel blocker, she opened the medication and walked in the patient room and did not check the blood pressure. I again stopped her to assess the blood pressure. Additionally, she admitted to not checking her patient who was in a brief for incontinence from 945 until 1240, despite signing the the paperwork that every hour she was assessing pain, potty, possessions and position.  I notified her this was false documentation. Ms.Ross and I will meet with Abby today November 13 to discuss my repeated concerns.
