Evaluating nursing practice through theories and models Essay

Evaluating nursing practice through theories and models - Essay ExampleModels become necessary when representations of several(a) interactions among different concepts needs to be shown and patterns established. Theories should be able to give nursing practice the foundation it needs in order to develop more intimacy in the area and provide the direction such a nursing professional practice needs to take (Alligood & Tomey, 2002, pp.56-78). The paper looks at these nursing models and theories and in particular addresses the Florence Nightingales Legacy of Caring Orem Theory and Paplaus Theory and points out their at a lower placelying theoretical and evidence base for each of them. The strengths and weakness of each of these theories are likewise discussed. A case study will be carried out on one of these models and theories to help illustrate its application further. This case study involves how to take treat of peripherally inserted central catheter paediatric patients for chem o therapy purpose long term care. The peripheral IV devises are those cannula that are inserted into a peripheral vein that is small for purposes of therapy in cases where medications, blood products or fluids need to be administered to patients. The peripherally inserted central catheter devices or PICC are usually inserted into brachial veins or basilica or cephalic veins and do get into the large vein or superior vena cava. Little is however known regarding the risk of complications in applying these devices to paediatric patients with crabmeat who are under chemotherapy (Callaghan, et al., 2002, pp.256-64). This will be further illustrated by taking into account the metaparadigms in nursing application such as infection Control of this condition, relevant gentility that is needed, health situation, the environmental setting, and the kind of nursing required. A... The objective of this research is to acquire a better insight of nursing models and theories. There are various mod els that have a bun in the oven been put forward in the nursing profession to help in the evidence based practices. Some of these models and theories include, but not limited to, Florence Nightingales Legacy of Caring, Orems Theory, Paplaus Theory, Neumanss Health Care System Model, Myra Estrin Levines The conservation model, and Patricia Benners Primacy of caring, among others. Indeed the importance of models and theories in nursing profession cannot be overemphasized because they hold a critical point in the evidence-based nursing practice which cannot be ignored if professional practice is to be upheld. These concepts are very useful in the success of any nursing professional in providing healthcare to his or her patients. The theoretical models discussed above have been used in various medical settings in assisting patients recognise and deal with their conditions.Paediatric patients on chemotherapy need special care. PICCs are a choice for patients who need long-term IV acce ss and many practitioners would choose PICCs imputable to the fact that they are durable and pose fewer problems when it comes to insertion and their removal after use. There is however a high rate of complication with cancer patients when PICCs are used, especially during chemotherapy. But that aside, the fact that these PICCs do not require a surgical procedure, less pain experienced during insertion, and ease of removing them after use, reap PICCs preferred for patients especially paediatric patients under chemotherapy.
