title: Content validation of the operational definitions of the nursing diagnoses of activity intolerance, excess fluid volume, and decreased cardiac output in patients with heart failure.
abstract: OBJECTIVE
  To consensually validate the operational definitions of the nursing diagnoses activity intolerance, excessive fluid volume, and decreased cardiac output in patients with decompensated heart failure.
  
  
  METHODS
  Consensual validation was performed in two stages: analogy by similarity of defining characteristics, and development of operational definitions and validation with experts.
  
  
  RESULTS
  A total of 38 defining characteristics were found. Operational definitions were developed and content-validated. One hundred percent of agreement was achieved among the seven experts after five rounds. "Ascites" was added in the nursing diagnosis excessive fluid volume.
  
  
  CONCLUSIONS
  The consensual validation improves interpretation of human response, grounding the selection of nursing interventions and contributing to improved nursing outcomes.
  
  
  CONCLUSIONS
  Support the assessment of patients with decompensated heart failure.
