Critique of Clinical Skill - Essay Example Critical appraisal is a systematic process utilized to identify research strengths and weaknesses inherent in a research article. This is done with an aim of assessing the validity, reliability and usefulness of research findings. The primary components of critical appraisal include the evaluation of the study design’s appropriateness for the research questions used, and the careful assessment of key methodological design features. Other factors that should be taken into consideration while critically appraising an article are such as the examination of the suitability of the statistical methods used to analyze data, potential conflict of interest and the research relevance to an individual practice. Thus, the purpose of this paper is to appraise the below named article on wound management. Article: Annells, M., O’Neill, J., & Flowers, C. (2008). Compression bandaging for venous leg ulcers: the essentialness of a willing Patient. Journal of Clinical Nursing, 17(3), 350- 359.doi 10.1111/j. 1365-2702.2007.01996.x Analyzing whether the Research Study Questions Are Relevant A research can be of the highest methodological rigor but it may be of little value if it does not address a significant topic or add value to the already existing knowledge about the subject under discussion (Mays & Pope, 2000). The article sought to find answers to the following question â€Å"why do or why don’t district nurses use compression bandaging as a component of the management of venous leg ulcers?† The aim of the study was to help identify both constraints and enablers. The research question is relevant because it seeks to explain why some and not all nurses utilize compression management to manage venous leg ulcers. In addition to that, the study findings contribute to the existing knowledge because less has been documented as to why compression bandaging is not often used by district nurses in the treatment of venous leg ulcers. Furthermore, the research question is relevant to the clinical practice. As a result of the study, factors that might constrain the willingness of the patient to apply compression bandaging in the treatment and maintenance of the venous leg ulcer were identified. Then, the actions that need to be performed to facilitate patient willingness were recommended. Does the Study Add Anything New? Any scientific research aims at developing new knowledge and ideas on the basis of work done previously (Hawking, 2003). As a result of this particular research, district nurses were made aware of the significance of evidence-based practice. Proper understanding of the findings of the study will support the planning carried out by the district nursing organization. As a result, there will be an improvement in the rate of appropriate use of compression bandage on venous leg ulcers. The increased use will be facilitated via the provision of relevant resources and the needed education. Moreover, the research findings will up date nurses on how to appropriately asses venous leg ulcer patients. Similarly, the nurses are able to plan and implement strategies for best practice care which is sustainable and patient driven. The research adds new knowledge to the work done previously. The Type of Questions Posed By the Study The most significant task of critical appraisal is the identification of the specific research questions being addressed by the article.

Volcano Probe Essay Example | Topics and Well Written Essays - 1000 words

Volcano Probe - Essay Example Pressure and temperature changes in a volcano leads to its structure and its overall behavior in regard to the period of formation to the eruption period. It is pressure and temperature that explains how a volcano is formed and how it erupts on to the earth surface in the long run (Beatty, 1998, p. 67). In general volcanoes normally occur in areas where tectonic plates diverge or converge or where the earth crust stretch or thin as in the case of African Rift Valley. Similarly, volcanoes can arise as a result of mantle plumes or hotspots which may occur far from the platonic plate's boundaries. Where volcanoes occur due to divergence of platonic plates, new oceanic crust is formed by hot molten lock or the magma which slowly cool and solidify. In essence, the crust is very thin at these ridges as a result of tectonic plates pull. Pressure resulting from the crust thinning gives rise to adiabatic expansion with a new oceanic crust forming as a result of partial melting of the mantle. In regard to converging platonic plates, the collision of a continental plate and an oceanic plate results into a subduction zone which by extension results into the submersion of the oceanic plate under the continental plate. The subducting layer releases water which lowers the temperature of the mantl e wedge above the result of which is magma creation. On the other hand, hotspots which are commonly located above mantle plumes where there is convection of the mantle of the earth results into a column of hot material that rises up to the earth crust. Plume temperature causes the crust to melt forming pipes useful in venting magma (Beatty, 1998, p. 98). Following the above discussion, designing a volcano probe would require one to properly analyse the factors and forces behind volcano formation. In essence, one would be required to put into consideration the thermal forces involved and it is at this point that knowledge of thermal physics becomes essential. In this case, one would be required to design a temperature and pressure measuring system that is compatible with changes in the two parameters and which can withstand huge changes for that matter. As such, one would be required to consider the materials with which the pressure and temperature measuring system is built from as some materials may not be able to withstand huge changes in these two parameters. For example, metals are known to melt under different temperatures with some melting at lower temperatures than the others. Still, some of these metals when exposed to high pressures react or behave differently from the others (A.I.P. 2000, p. 56). Any component designed to study the behavior of a volcano will have to put into consideration all the thermal physics aspects of pressure and temperature among other things. Such things include the permissible pressure range of the pressure sensor and the temperature range of the temperature sensor to be used in the measuring instrument. Equally important is the pressure and temperature range of the outer structure inhibiting the sensors. Moreover, the data collected by these sensors will need to be transmitted to a receiver through a transmitter.
