The aim of this study is to analyze the quality policy implemented by the hospital management in the central chemistry and the characteristics of the medication activities performed by the nursing assistants (NA).The approach of the French School of Ergonomics was adopted. It was assessed the Hospital working situation and the activity performed by the nursing assistant in real time which have allowed to understand the difficulties faced by the workers and the strategies adopted to overcome them. It was observed that the working activity is part of an organizational paradox where the expected quality to fulfil the medication mission has been difficult to achieve, endangering, ultimately the assistance to the patients.
