Objective: To evaluate adherence to hand hygiene in a nephrology service. Method: Descriptive study, performed in a public hospital in Teresina, Piauí, Brazil. Adherence percentage to five moments of hand hygiene was collected in a database of Center for Patient Safety in the period from March to April 2019. Results: Adherence rate varied in all the periods analyzed, reached 25% of adherence, and there were almost no stabilization periods. By relating the variation of adherence rate with the activities performed in the same period, it may be inferred that the greatest number of professionals who participated in educational activities on hand hygiene influenced in the increased adherence rate. Conclusion: The adherence was low; therefore, it is necessary that educational interventions be constant and not punctual so that hand hygiene becomes routine inherent in care.

Objective: to analyze the biosafety measures adopted by nursing undergraduates in daily activities in spaces of laboratory practices.Method: descriptive, qualitative analysis study performed at a Higher Education Institution in the period from April to June 2018, with 30 students. For the analyses of interviews, Collective Subject Discourse was utilized. Results: as for Personal Protective Equipment (PPE) usage, 24% used gloves, followed by white coat and mask, with 19% and 18% each, respectively. Referring to moments of Hand Hygiene (HH) during the laboratory practices, 32% performed the hygiene before and 26% after the practice. It is observed that the scholars’ knowledge about biosafety is broad but limited to PPE usage. Conclusion: it is verified that the use of biosafety measures in this environment is still a challenge, for it be limited to PPE and HH usage.
