Assignment 2 - Differentiating age changes from pathological changes

2 - Differentiating age changes from pathological changes - Assignment Example It also causes profuse sweating, increased breathing and pulse rate (Nadel, 2008). A bluish colour may appear in the lips and nails due to the reduce oxygen in the blood. This causes confused and delirious mental state to the patient. Coughs- this because of reduced output of the respiratory system causing abnormal respiratory responses. This is because chest bones become thinner which causes a shape change of the ribcage. Thus the ribcage expands less during breathing. This can also be attributed to changes in the immune system thus the lungs recover less from exposure to harmful particles (Cook, Zumla, A & Manson, 2009). Chills- metabolism becomes slower as one ages therefore heat generation by the body is low thus muscles have to provide alternative means to generate heat. This reduction in metabolism is due to the thyroid becoming lumpy thus affecting the production of hormones that are responsible for metabolism. Shortness of breath and tiredness- as one grows older; muscles that support the diaphragm are weakened. This causes the airways to lose their ability of keeping the airways open. Causing them to close easily. This can be attributed to loss of shape and bagginess of the alveoli. All these changes in lung tissue causes air to get trapped in the lungs thus not enough oxygen reaches the capillaries. Removal of carbon IV oxide is reduced making breathing hard. Headache – headaches maybe more frequent as one ages because of a number of reasons. One is that due to reduction in blood pressure that can prevent enough blood reaching the brain thus causing dehydration of brain cells causing minor headaches and light headiness. Drop in blood pressure can occur also due to the reduction in aldosterone hormone which in turn can indirectly or directly cause headaches. Fatigue – can be caused by the various factors. One key factor is the reduction of central nervous system functionality. This can also be attributed to reduced metabolism and

Problem Formulation and Identification - Essay Example This reduces the cognitive demands involved in making decisions by restricting the range of issues that must be considered. Typically, past experience in similar situations provides guidance in framing situations. Without prior experiences, decision makers must consider a large array of issues to evaluative standards and derive an appropriate interpretation. Computer supported decision making allows to identity the process of determining what knowledge is relevant. It is made in order to act upon the world, to make sure that the future does not look like the past. This process helps to save time and avoid anxiety, delays in decisions and action. Also, computer supported decision making is about making the best decision at given conditions at the moment; it is specifically about process and only indirectly about outcome. In a computer service support organization, decision makers go to great lengths to insure that they have the ability to control key future events, and controllability is factored into their decisions. The main problem is that observed that corporate decision makers usually rely on their "subjective mode" to make decisions, even when extensive, computerized technology is available. Critics explain that because the databases for deriving probabilities and projecting trends consist of records of past events, the probabilities and trends are "backward looking" and therefore of questionable pertinence to decisions that often concern time frames projecting 20 years or more into the future. A decision making expert system allows managers to solve day-to day problems. By the same token, reliance upon data about the past assumes that the world is static; the data are useful only for predicting what will happen if the future looks a great deal like the past, or if identified trends continue (Decision Making Techniques n.d.). For problem identification and formulation, the organization can use balanced scorecard analysis. One first identifies
