The Roles & Responsibilities of Licensed Practical Nurse Research Paper

The Roles & Responsibilities of Licensed Practical Nurse - Research Paper Example Apart from this, LPNs also perform the basic duty of gathering and collecting the information from the patients who are going to be admitted to the hospital or medical healthcare facility. This is one of the primary responsibilities of LPNs to collect correct and accurate information in order to provide the doctors with correct information in assisting best course of action for a patient. LPNs also are also required to administer any injections or medications which have been prescribed by the doctors. Dressing up of the physical wounds as well as helping doctors in other similar tasks. (Duncan & DePew, 2010) It is, however, important to note that over the period of time, the demarcation line between the roles of LPNs and RN’s have blurred a lot. There are a lot of overlapping roles and responsibilities which are performed by both. This evolution in the roles and responsibilities of the LPNs has now become one of the permanent factors of the practice which is now being considered. One of the major force which is reshaping the roles and responsibilities of the LPNs is the major health care reforms. Health care reforms have changed the way nurses now actually view their roles in the overall larger context of the organization. Healthcare organization, in order to meet the changing healthcare needs as well as meet with the skill shortages, have actually allowed LPNs to evolve and expand their roles to accommodate those changes. Another important force which is shaping the way the overall roles of LPNs is changing is the improvements in the overall study and curriculum which has greatly enhanced the overall scope of the nursing practices. Over the period of time, research on the subject of Nursing has actually expanded the scope of the profession and has added some additional roles and responsibilities which have now been additionally added to the traditional roles of the LPNs.

Environment and Evolution of human being Research Paper

Environment and Evolution of human being - Research Paper Example nce has been collected through considerations of facts like fossils of the early human skull and concurrent bone structure that indicated the presence of the differences in the structure of human with respect to respective age period in the past. Such differences were notable in the human skull morphology, for instance, in some human species like Lucy. The stand has been further supported by Adrienne Zihlmans article regarding "paleosols" that hugely back up the relationship between environment and human evolution (Penna, 2010). According to (Haviland, 2007), the current theory and entailed elaborations on the evolution of man attains its backing from a set of independently notable observations well placed in the fields of anthropology, molecular biology and other sectors like paleontology. All the three segments outline or exhibit life originating from a common point of ancestor and then branching into various categories under a gradual and progressive genetic changes spanning millions of years in a "tree of life" that is hugely influenced by environmental variations. Evolution of man similar to other animals in the ecosystem has been impacted by the environment that has consecutively acted in the formats of three main principles. The first principle is through microevolution that refers to the presence or the occurrence and establishment of build-up of mutations acting on the genetic sequence of an organism. The environment created huge impacts on established of the new establishment of build-up of mutati ons acting on the genetic sequence from the historic ancestor of man. Though the change can equally occur naturally. Several environmental effects have been linked to the microevolution of the mankind especially those originating from different geographical regions. The main environmental variations includes existent chemicals and varied earth radiations notable in various parts of the earth. Environmental radiations is believed to contribute to the difference
