A
According to systems theory, a system is made up of parts that depend on one another, are inter-related, share a common purpose, and together form a whole. A client's interaction with the en-vironment is an example of an open system. The nurse understands that factors that change the environment also can have an impact on the system.
Maslow's hierarchy of human needs is an interdisciplinary theory useful in planning individual-ized care.
Determining a client's attitudes toward health behaviours follows a health and wellness theoreti-cal model.
Focusing on the response of a client to the process of growth and development is consistent with developmental theories.
