The practice of nursing is defined as diagnosing and treating human response to actual or potential health problems through such services as case finding, health teaching, health counseling and provision of support to or restoration of life and well-being and executing medical regimes prescribed by licensed or otherwise legally authorized physician or dentist. The nursing process is an orderly systematic manner of determining the patient’s problems, making plans to solve them, initiating the plan or assigning others to implement it and evaluating the extent to which the plan was effective in resolving the problems identified.
