Faye Abdellah, a pioneering nurse and theorist, developed a typology of 21 nursing problems that emphasizes the need for patient-centered care across physical, emotional, and sociological dimensions. Her theory suggests that nursing integrates art and science to address comprehensive health needs, focusing on effective communication, emotional support, and the involvement of family in care processes. While her approach is beneficial for structuring nursing education and strategies, it is critiqued for being overly nursing-centered and lacking emphasis on patient outcomes.
