A young female patient was admitted to the ICU in critical condition due to acute pulmonary embolism with hemodynamic instability and severe respiratory impairment.The nurse,as a key member of the interdisciplinary team,recognizes early predictive signs of clinical deterioration and formulates NANDA diagnoses(clinical judgment about a person’s, family’s or community’s responses to actual or potential health problems and life processes)such as “Impaired Gas Exchange”,“Ineffective Cardiopulmonary Perfusion”, “Risk for Bleeding” and “Anxiety”.The ICU nurse, through advanced technical expertise in hemodynamic monitoring, ventilatory support, and the management of complex therapeutic regimens, ensures a safe and highly effective standard of care.The nursing care plan is based on a systematic process that integrates technical and scientific competencies with the ability to recognize and respond to the patient’s psychological and relational needs.Family support constitutes an essential component of the care pathway, contributing to stress reduction, enhanced communication and continuity of therapeutic management.The corresponding NOC(Nursing Outcomes Classification, standardized classification of patient outcomes developed to evaluate the effects of nursing interventions)allows timely and targeted care planning. NIC(Nursing Interventions Classification, standardized classification of evidence-based nursing interventions that describes the treatments nurses perform to enhance patient outcomes)guides acute-phase management,including advanced vital signs monitoring,non-invasive ventilation, management,regulation of anticoagulant therapy and implementation of bleeding and infection prevention strategies.Continuous interaction with the medical team allows immediate life-saving interventions and dynamic evaluation of clinical response.Active listening and empathy play a crucial role in modulating anxiety, supporting coping, and enhancing therapeutic adherence.The nurse facilitates communication between patient and team,contributing to decision-making and personalized care pathways.Progressive respiratory and hemodynamic stabilization,effective management of complications,reduction of oxygen therapy and recovery of autonomy,confirm the achievement of the planned NOC outcomes.The transition to oral anticoagulant therapy marks the end of the care pathway,highlighting the impact of a nursing approach based on diagnosis,planned interventions and outcome evaluation.
