The document provides guidelines for use in the right diagnosis and the proper treatment of children between ages 2 months to 12 years with symptoms of AOM. The source is just a guideline meant to provide some basis or framework when coming up with clinical conclusions about making correct clinical decisions. The source does not provide full details of evidence and nurses cannot use it as the only source to guide them during management of children with AOM. The source is also an evidence-based guideline compiled by different experts creating a comprehensive report. Even though it lacks the specific research details, it is very helpful since it provides important information for nurses on pain management, observation, antibacterial treatment, and preventive measures. The practical guidelines of the article, supported with adequate reasons, and summaries of findings of the study, makes this article very resourceful and appropriate for this nursing practice situation. Block, S. L. (1997). Causative pathogens, antibiotic resistance, and therapeutic considerations in acute Otitis media. Pediatric Infectious Disease Journal, 16, 449- 456. This source of evidence can be classified as unfiltered resource because its source comes from the research studies of the author. The recommendations and views of the work are typically those of the author and since most of the information in the article particularly in the conclusion part represents views and recommendations of the author, it is certainly un-filtered. The resource nature makes it an evidence summary, because the authors made a summary from existing evidence. The source gives a clear-cut specific evidence of the pathogens that cause Acute Otitis Media (AOM) and the effectiveness of various antibiotics for treatment. Its drawback is that it does not provide a detailed report about other lines of treatment or alternative approach in treating AOM. In such a case, the nurses may miss some important information on treatment therefore; some more important and relevant research findings should be included. The fact that this resource paper is an evidence summary then the details missing makes it to be less helpful to the nurses. It is therefore not a proper guideline for use by the nurses in such a situation. Kelley, P. E., Friedman, N., Johnson, C. (2007). Ear, nose, and throat. In W. W.Hay, M. J. Levin, J. M. Sondheimer, & R. R. Deterding (Eds.), Current pediatric diagnosis and treatment (18th ed., pp. 459±492). New York: Lange Medical Books/McGraw-Hill. The source of evidence is an incomprehensive resource because it provides research work of the author. The source gives a comprehensive report on various causes of ear infections, antibiotic resistance in the treatment of AOM and the challenges doctors face when looking for alternative treatment choices. The source therefore addresses specific issues, which nurses can find to very resourceful, relevant, and helpful when dealing with a situation at hand. The author’s recommendations and conclusions will be of great help to the nurses too. The resource falls under the category of summary of evidence since the authors used the actual research work of the author to create the summary. Even though the source is quite narrow and specific, the results and conclusions are very relevant and this makes it appropriate for this nursing practice situation.
