Prophylaxes are the foundation and prerequisite for any professional care. Trainees gain comprehensive knowledge as an essential basis for their future nursing activities. For nursing practitioners, in-depth knowledge of the application of prophylaxes is the guarantee of demanding professional care. The present expanded and revised second edition of the workbook helps to deepen knowledge of prophylaxes in a clear manner, as it is conveyed in a current, comprehensive, and practice-oriented way. Each chapter addresses a prophylaxis in the form of various types of questions, such as crosswords and case studies. This allows for an engaging and effective deepening of knowledge. In combination with an attached solution chapter, targeted revisions, for example before exams, are possible. For nursing educators, the workbook serves as a resource for lesson planning.
