WITH SOLUTIONS GRADED A+
◉ Dynamic homeostasis. Answer: refers to the processes used by a
system to maintain a steady state or balance. Feedback loop-goal of
maintaining a steady state can affect how clinical settings respond when
changes are made or a new system is implemented.
◉ Equifinality. Answer: is the tendency of open systems to reach a
characteristic final state from different initial conditions and in different
ways. Example: two different clinics with different charting systems
adopt a new system, and end up with the same result.
◉ Entropy. Answer: is the tendency of all systems to break down into
their simplest parts. As it breaks down the system becomes increasingly
disorganized or random.
In data transmission, entropy measures the loss of information when a
signal is transmitted.
All systems eventually must be replaced.
, ◉ Negentropy. Answer: is the opposite of entropy. This is the tendency
of living systems to grow and become more complex.
◉ Reverberation. Answer: is reflected in the intended and unintended
consequences of system change. Chaos theory was developed in the 50s
to explain the phenomena of unintended consequences.
◉ dynamic systems. Answer: chaotic systems. While chaotic systems
vary in their state of stability, they are in a constant state of change. The
change is nonlinear. In a nonlinear system the output of the system is not
proportional to the input.
◉ reiterative feedback loop. Answer: major impact on how imput affects
output. A minor change in input can cause a major change in output
(butterfly effect).
◉ fractal-type patterns. Answer: while the output or behavior of a
chaotic system will appear unstable, aperiodic, and even random, these
systems are deterministic. Their output is determined by the initial input,
reiterative feedback loops, and the dynamic changes that occur over
time. Out of chaos comes order: snowflake
◉ chaos theory. Answer: Both chaos and complexity theory involve the
study of dynamic nonlinear systems that change with time and
demonstrate complex relationships between inputs and outputs due to
reiterative feedback loops. "The quantitative study of these systems is
