Nursing  theorists  have   contributed  towards the  development  of  a  body  of  knowledge to the profession. Benefits of  having  a definite body of  knowledge include quality patient care and improved professional  status. Nurses need to  recognise the need for utilising nursing theories  to  practice. The demand  for  evidence  based  practice  have  gained  great momentum  in  the current  Nursing scenario. A shift  from  theory  development  to  theory  utilisation  has  contributed  to  a variety  of  scholarly  approaches to  practice  of  nursing. The purpose of this article  is  to  illustrate successful use  of  nursing  theories in various practice settings. Nursing  theorists have tried to  explain  nursing in their  own  perspectives and it is the challenge of  individual  nurse  to  utilise the one suited to  their setting.
