Part of the power of a healthcare system which emphasizes preventative medicine is in regular checkups Many patients arent equipped to sufficiently monitor all the facets of their own health and the quotidian requirements that are necessary to maintain it Doctors take measurements and keep records of numerous statistics such as blood pressure which can be used to establish a history. The nurse is usually responsible, along with other health care professionals, for the treatment, safety and recovery of acutely or chronically ill or injured people. A nurse also cares for the health maintenance of the healthy patient and treatment of life-threatening emergencies in a wide range of healthcare settings. Nurses may also be involved in medical and nursing research and perform a wide range of non-clinical functions necessary to the delivery of health care. Nurses are also instrumental in providing care during the birthing process and death.
