Concept Comparison and Analysis Across Theories
Core concepts embody a theory creating the bases for the theory or model.   In nursing, concepts help in the development of theories.   Theorists have developed different models or theories but have common core concepts.   This paper will identify a core concept that several theorists have in share compare and analyze the concept definitions among the selected theories, and discuss the practical use of the one theory
Common Concept
The core concept common to two or more theories is nursing.   Dorothea Orem’s and Virginia Henderson’s use the nursing concept in their theory to define the role of nursing.   Orem defines nursing as the “actions deliberately selected and performed by nurses to help individuals or groups under their care to maintain or change conditions in themselves or their environments”(Current Nursing, 2010, para. 4).   Henderson defines   nursing as nurses assisting the individual, ill or healthy, in the performing activities   that contribute to the individuals health or recuperation(even a peaceful death)   that the individual performs without help if armed with   strength, resolve or information (Current Nursing, 2010, para. 6).   The concepts are common in that nursing support the patient in recovering their optimal health.   An individual that is experiencing difficulties or self-care deficit Orem defined need nursing interventions.   The difference in Henderson and Orem’s nursing concept is that Henderson’s concept determines that nursing is needed when the individual is healthy or sick.   In contrast, Orem’s nursing concept requires patient to have a self-deficit for nursing support. The concepts are applicable in different nursing settings because the goals of both concepts are the same
