    Introduction: The construction and validation of an instrument to evaluate nurses' knowledge about medication administration in patients with acute myocardial infarction can contribute to a safe and quality nursing care. Objective: To construct and validate a questionnaire to evaluate the knowledge of nurses about medications used for the treatment of ST-segment elevation myocardial infarction (STEMI). Methods: A methodological study that involved the construction and validation of the content of a questionnaire, as well as a semantic and idiomatic review. The degree of agreement among judges was assessed by the Content Validity Index (IVC ≥ 0.8). Results: The validated questionnaire consists of 20 questions divided into 4 sessions: I- Expected action of the medication, II- Adverse effects, III- Nursing care, IV- Route of administration and V- Contraindications. In the evaluation of the judges 19 questions obtained IVC≥0.8; 7 questions were corrected and 1 question was reworked as suggested by the judges. Conclusion: The questionnaire constructed in this study provides a validated and reliable data collection instrument for the evaluation of nurses' knowledge on the topic of medications used to treat STEMI.Introdução: A construção e validação de instrumento para avaliar o conhecimento dos enfermeiros quanto ao tema administração de medicamentos em pacientes acometidos por infarto agudo do miocárdio pode contribuir para a busca de uma assistência de enfermagem segura e de qualidade. Objetivo: Construir e validar um questionário para avaliar o conhecimento de enfermeiros sobre os medicamentos utilizados no tratamento de infarto agudo do miocárdio com supradesnível do segmento ST (IAM CSST). Métodos: Estudo metodológico de construção e validação de conteúdo de um questionário, além de revisão semântica e idiomática. O grau de concordância entre juízes foi avaliado pelo Índice de Validade de Conteúdo e considerado ponto de corte (IVC ≥ 0,8). Resultados: O questionário validado está composto de 20 questões, divididas a cada 4 nas sessões: I- Ação esperada do medicamento, II-Efeitos adversos, III-Cuidados de enfermagem, IV- Via de administração e V-Contraindicações. Na avaliação dos juízes, 19 questões obtiveram IVC ≥ 0,8; 7 questões passaram por correções e 1 questão foi reelaborada conforme sugestões. Conclusão: O questionário construído neste estudo fornece um instrumento metodológico de coleta de dados validado e confiável para avaliação do conhecimento de enfermeiros sobre os medicamentos utilizados para tratamento de IAM CSST

    Seasonality of soil water exchange in the soybean growing season in southern Brazil

    The processes of water transfer in the soil-plant-atmosphere system are strongly affected by soil use and management. Differences in the dynamics of soil water transfer between no-tillage (NT) and conventional tillage (CT) practices during a soybean (Glycine max) growing season in southern Brazil were assessed in this study. All the water balance components were analyzed during the soybean growing season (2009/2010). Rainfall, runoff, soil water storage and hydro-physical soil properties were analyzed under two tillage systems. The land-atmosphere water vapor exchanges, obtained from eddy covariance stations, were analyzed with regard to the soybean agroecosystem. Characterizations of soil water storage were also formulated in the 2006/2007 and 2008/2009 soybean growing seasons under the NT system. During the periods without rain, the soil water content under NT was greater than under CT. The soil superficial layer, more porous under NT, contributed to less runoff during rainy events. Moreover, under NT conditions the water supply was always high, between 0.2 - 0.5 m. The total evapotranspiration in the soybean agroecosystem growing season was 410.8 mm
