This document provides an overview of NANDA (North American Nursing Diagnosis Association) and functional health patterns. It defines NANDA as clinical judgments about individual, family or community responses to actual or potential health problems. It lists the 12 functional health patterns which are tools for nursing assessment: health perception, nutritional, elimination, activity, sexuality, sleep, sensory, cognitive, role relationships, coping, values and beliefs. For each pattern, it provides examples of subjective and objective data to collect and potential nursing diagnoses. The overall document serves as a guide for nursing students to learn about assessment and formulation of nursing diagnoses.
