Objective: to analyze the correspondence between actions contemplated in the safety protocol on medication prescription, use and administration of the Ministry of Health with interventions of the Nursing Interventions Classification, by means of cross-mapping. Method: a descriptive study developed in four stages: extraction of the protocol’s Nursing actions; identification of the interventions of the Nursing Interventions Classification; cross-mapping; and cross-mapping validation by experts. Results: 61 actions of the protocol and 32 interventions of the Nursing Interventions Classification were identified. After two rounds of mapping analysis by the experts, correspondence was identified between 53 actions and seven interventions. The interventions that presented the highest correspondence were the following: Medication Administration, Medication Management and Medication Prescription. Of the 53 mapped actions of the protocol, 56,6% were considered more detailed and specific than the activities of the interventions, 20,8% were classified as similar in meaning, 17,0% as broader and general, and 5,7% were only mapped with the title and definition of the intervention. Conclusion: the mapped actions of the protocol were considered more detailed and specific in relation to the activities of the interventions of the Nursing Interventions Classification. The unmapped interventions can contribute to elaborating operational protocols that expand the Nursing actions related to the mitigation of medication errors.
