EXERCISE 2 My involvement in the drug error is as follows. I was working on the night shift as the only qualified nurse with 2 nursing assistants. The late shift decided to administer the 10pm medications as a way of helping me. This however was key in me making the error that I did. If I had been left to do the 10pm medications by myself‚ this error would not have occurred. Patient PF was given her medication by the late staff‚ however she had spat them out. On going to give her these

concentration to an area of low concentration across a semi permeable membrane. An osmotic system is established when a semi-permeable membrane is placed between two solutions. In this biological systems context‚ osmosis is the exchange of water between the potato cell and the surrounding medium of varying sucrose concentrated solutions‚ with the plasma membrane being the semi- permeable membrane. Because water molecules have kinetic energy‚ they are constantly moving around in gaseous or liquid form‚ moving

Abstract Molar volume is the volume that one mole of gas occupies when temperature and pressure are kept constant. The molar volume of a gas can be determined through evaluating how much gas is given off when the number of moles of the substance is known. To find the volume of gas that will be used to calculate the molar volume‚ the process of water displacement can be used. Reference Citation Cesa‚ J. (2002).

Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more

With reference to research discuss two errors in attributions. (22 marks) The Attribution Theory is a concept of social psychology that makes reference to how individuals feel the need to provide ‘cause to the events around us’. Fritz Heider first proposed the theory ‘The Psychology of Interpersonal Relations (1958)‚ which was later developed by others such as Harold Kelley and Bernard Weiner. The developed definition of this theory refers to the role of our minds in relation to our social behaviour

Unlike Incident Management metrics like "percentage solved within target time"‚ Problem Management metrics are typically not included explicitly in Service Level Agreements (SLAs). Setting up a Known Error Database (KEDB) is another key activity. A Known Error is a Problem that has a documented root cause and workaround or solution. The KEDB maintains information about problems (i.e.‚ isolation and resolution procedures) and the appropriate workarounds‚ scripts‚ references to

The Portrayal of Women in The Comedy of Errors Through the centuries‚ women have tried to be equal to men. From their position in the place of work to voting rights‚ women have struggled to gain equal rights. In Shakespeare’s play The Comedy of Errors‚ women are very present. Shakespeare presents two important women: Adriana and Luciana. They are each portrayed differently. Adriana represents the feminist point of view and Luciana‚ the anti-feminist. To begin‚ Adriana is the most present female
