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