The formula for theoretical calculation of attenuation A is the attenuation due to conductors plus attenuation due to the dielectric: As can readily be seen, attenuation would increase as the frequency increases. In a perfect cable, the pattern of increasing attenuation would be exact and regular. However, on the practical side, this is difficult to achieve and for that reason, tolerances are specified.

They are derived through two principal methods; deductive reasoning and inductive reasoning. Objectives to assess the patient condition by the various methods explained by the nursing theory to identify the needs of the patient to demonstrate an effective communication and interaction with the patient.

Definition Nursing theory is an organized and systematic articulation of a set of statements related to questions in the discipline of nursing.

Importance of nursing theories Nursing theory aims to describe, predict and explain the phenomenon of nursing It should provide the foundations of nursing practice, help to generate further knowledge and indicate in which direction nursing should develop in the future.

Theory is important because it helps us to decide what we know and what we need to know It helps to distinguish what should form the basis of practice by explicitly describing nursing. Later in last century nursing began with a strong emphasis on practice.

Following that came the curriculum era which addressed the questions about what the nursing students should study in order to achieve the required standard of nursing. As more and more nurses began to pursue higher degrees in nursing, there emerged the research era.

Later graduate education and masters education was given much importance. The development of the theory era was a natural outgrowth of the research era.

With an increased number of researches it became obvious that the research without theory produced isolated information; however research and theory produced the nursing sciences. Within the contemporary phase there is an emphasis on theory use and theory based nursing practice and lead to the continued development of the theories.

Bases for hypotheses that can be tested. Increasing the general body of knowledge within the discipline through the research implemented to validate them.
