ABSTRACT Objective: To construct and validate nursing diagnoses statements of the International Classification for Nursing Practice (ICNP®) for the person with diabetic foot ulcer being followed up in primary health care. Method: This is a methodological study structured in four stages: identification of terms; cross-mapping of identified terms with ICNP terms®, version 2019/2020; construction of nursing diagnoses statements and organization with Orem’s Theory of Self-care; and content validation by expert nurses working in primary care, with those with Content Validity Index (CVI) ≥ 0.80 being considered valid. Results: Eighty-one diagnostic statements were constructed, five of which were positive, 67 negative, and nine risky. Of these, 58 were included in ICNP® and 23 were not, 51% of which were categorized as self-care requirements related to health changes. Conclusion: ICNP® subsidized the construction of a technical product, which can be consulted and used by nurses and will allow the strengthening of the standardization of a specific language in the context of care for people with diabetic foot ulcers in primary health care.
