ABSTRACT Objectives: to describe the development of an ICNP® terminology subset for Nursing Consultation to infants in Primary Health Care. Methods: a methodological study, described in five stages, carried out from May to September 2018 with 15 nurses who identified diagnoses, results, interventions, and validated the subset content. Results: the subset developed consists of 86 nursing diagnoses and results and 178 interventions, organized in the fields of Theory of Basic Human Needs. Final Considerations: the subset contributed to implement the systematized Nursing Consultation, assisting nurses in decision making. Construction and validation consolidate evidence-based practice, bringing the subset closer to practical reality, in addition to contributing to infant health care qualification.
