RESUMEN
A new perspective developed at Mansoura University Hospital is to provide quality patient care. The responsibility of ensuring quality patient care units falls directly on the shoulders of the head nurses. So, Job description is needed more than ever to have a written statement of: organizational relationships, duties, responsibilities as well as qualifications of the head nurses. Thus, this study aims to develop and validate job description of the head nurses in the surgical units at Mansoura University Hospital. The sample consists of all head nurses [10 head nurses] in the surgical units and 12 nurse supervisors at Mansoura University Hospital. There is also a jury group includes 15 different levels of nurse managers working at Mansoura University Hospital and 15 academic staff from Faculty of Nursing at Mansoura, Ain shams, and Cairo Universities. Three tools were used for data collection, namely: an observation sheet [activity analysis], a job description questionnaire, and opinionnaire sheet. The study findings indicated that the proposed job description is valid to be used in the general surgical inpatient units at Mansoura University Hospital. It is recommended to be applied and to be up dated periodically
