Objective: to characterize the knowledge about the use of potentially dangerous drugs among hospital health care nurses.

Methods: quantitative, descriptive-exploratory research, with the application of a validated questionnaire, translated and adapted in Brazil, on potentially dangerous medications, with 26 nursing assistants in a university hospital. Univariate and bivariate descriptive statistical analysis of the data was performed using the Statistical Package for Social Science, version 20. Scores 70% were considered as sufficient knowledge and insufficient knowledge scores <70%.

Results: in the first domain of the questionnaire, called Medication Administration, the average percentage of correct answers was 64.6%. In the second domain, Clinical procedures, an average of 53.7% of correct answers was found. The use of electrolytes, chemotherapy and insulin were the main weaknesses in the knowledge of professionals.

Conclusion: insufficient knowledge about the administration and clinical procedures of potentially dangerous drugs was identified among hospital care nurses in this scenario. [ABSTRACT FROM AUTHOR]
