Content Validation of the Nursing Diagnosis 'Risk of Shock' in Individuals with Acute Myocardial Infarction.

ObjectiveTo validate the NANDA-I nursing diagnosis "Risk for Shock" through content analysis and expert evaluation.MethodsThis is a methodological study with a quantitative approach, conducted in two phases: (1) theoretical-causal validation of the nursing diagnosis Risk for Shock in individuals with acute myocardial infarction (AMI), and (2) content validation performed by subject-matter experts was conducted between March and September 2024, involving two rounds of expert assessment based on predefined criteria of expertise. The Delphi technique and the Content Validity Index (CVI) were employed, with a cutoff point of ≥0.80. The definitions, defining characteristics, risk factors, and at-risk populations related to the diagnosis were analyzed.ResultsA total of 62 experts participated in the first round and 51 in the second, predominantly female, with high academic qualifications and substantial experience in intensive care, cardiology, and the nursing process. In the first round, most indicators reached a CVI ≥ 0.80, except for some risk factors that were subsequently revised. In the second round, all diagnostic elements achieved consensus and satisfactory CVI, consolidating the validated diagnostic proposal.ConclusionThe nursing diagnosis "Risk for Shock" was validated in terms of content, presenting refined definitions and indicators for clinical practice, thereby contributing to diagnostic accuracy and patient safety.
