Clinical decision making is a core nursing responsibility that requires integrating various sources of knowledge. Nurses must consider evidence-based practices, patient values and preferences, clinical expertise, and other factors. There are several models that provide frameworks to structure clinical decision making processes. One influential model is Gillespie and Paterson's situated clinical decision making model, which identifies five categories of foundational knowledge nurses draw on: knowing the profession, self, case, client, and person. This model emphasizes the importance of considering both clinical factors and the unique attributes of individual patients when making decisions.
