Artifact Description:

This presentation compares Hildegard Peplau’s Interpersonal Relations Theory with Phil Barker’s Tidal Model using a clinical practice scenario. Creating this presentation strengthened my understanding of how nursing theories influence clinical decision-making and reinforced the importance of therapeutic relationships, person-centred care, and recovery-oriented practice. It also helped me recognize that different nursing theories can complement one another while offering unique perspectives on supporting patients.
