24hrs Urinary Urea Nitrogen Practical - Essay Example For example, a patient with a pathologically low blood pressure develops diminished urine flow. Nitrogen balance involves comparing nitrogen intake from foods and fluids with nitrogen excretion. Thus, nitrogen balance provides the clinician with an index of protein catabolism and a basis for assessing the adequacy of protein intake (Skipper, 1995; p. 86). In order to determine the nitrogen balance for each student in the group, data on the protein intake of these students must be acquired (Barakat et al., 2009) and inputed into the following formula: The dietary protein intake is best measured if the individual follows a standardized diet, that is, all the food that the individual eats must be measured before consumption, and duplicate meals must be prepared and analyzed for their nitrogen content (Manore et al., 2009; pp. 112-113). A minimum daily protein requirement is needed by the body to maintain its structural proteins, visceral proteins and immune competence. Conversely, when the body encounters certain stresses, its proteins also suffer level discrepancies. For example, starvation needs a progressive selection of fat as body fuel. Muscles stop utilizing glucose as soon as a meal is over and instead, fatty acids are used (Cahill, 1976). Ketoacid levels in blood become elevated over the first week, and the brain preferentially uses these instead of glucose. The net effect is to spare protein even further, as the brain further decreases the rate of using glucose. Nevertheless, there is still net negative nitrogen balance, but this can be nullified by amino acid or protein supplementation. In addition, protein kinetics are known to be accelerated in severe trauma. In fact, critically ill patients with major trauma demonstrate catabolism resulting in a net loss of body mass. Thus, the patient loses more nitrogen than is provided from nitrogen / protein sources (Wiliams & Shchlenker, 2003). The literature has varying ranges for the 24 hr UUN

Theories in Information Systems - Coursework Example The behavior of actors like a particular individual or a whole organization upholds these institutions. One cognitive view advocates that a socialization process encodes a particular institution into a given actor. When the actor internalizes it, this transforms into a patterned behavior (script). Then the institution is reflected in this patterned behavior of the actor. This leads to the continuous reproduction of the institutions. When these institutions are enacted through the behavior of the actors, then other actors are able to witness this. This is the external manifestation of the institution which gives rise to a new process of socialization. However, after the passage of time, this externalization of the institutions through the behavior of its actors becomes an accepted fact. Then, the actors sometimes fail to realize their own behavior is actually reflective of an institution. Persons sharing the institution view it as perfectly logical for the behavior of the actors to be influenced by the institution.Organizational Learning Theory: This theory states that â€Å"in order to be competitive in a changing environment, organizations must change their goals and actions to reach those goals.† There are certain actions that the firm must consciously undertake to foster learning.
