Depending on the requirements of the research, methodology can be given either qualitative or quantitative approach. Qualitative approach looks at why a certain trend is taking place (Minichiello, Aroni, Timewell, and Alexander, 1995). It explains reasons as to why a certain behavioural pattern is taking a certain shape, and the forces behind that particular trend. Quantitative research on the other hand looks at the magnitude of a specific phenomenon. It is a deductive process that estimates the quantities of the items involved in the study. It measures the extent to which the involved items in the research affect or are affected by other variables in the study. Most scientific research demands for both types of research methodologies as there may be the need to measure the extent to which the variables involved affect each other and the level of relevance for each (Mould, 1998). An investigation into decision making in health professional’s treating traumatically injured Jehovah’s Witnesses will demand for a qualitative approach to the investigation. This research involves explanation as to why a healthcare professional needs to take care of the patients’ interests in regard to their cultural and other beliefs. This may not be explained quantitatively as the data will be given a detailed explanation other than providing statistical overview. When a health professional is dealing with a patient, there are decisions that must be made, some of which may be against the beliefs of the patient. The main objective of this professional will be to ensure that the life of the patient is saved at all cost (Grbich, 1999). To have a full insight into the stages that are involved in this process of making decision during treatment, a qualitative method will be the most appropriate approach. French, Reynolds and Swain, (2001) assert that qualitative research into a topic provides a detailed knowledge into the subject matter, especially when it involves question of why a certain activity or action has taken place in a certain manner. 2.0 Annotated Bibliography Menezes MA., 2010. Life on the front line: exploring personal and professional Impacts on healthcare professionals working with fetal anomaly. Ph D Thesis, The University of Melbourne. Web. 9th January, 2012. In this article, the author explains that currently, health professionals are able to conduct both antenatal screening for pregnant women. This process may reveal certain anomalies in the foetus. In case such a professional detects such a case in a patient, then the professional must strive to rescue such a patient because such anomalies may be fatal if not treated in time. The concerned health professional must therefore make a quick decision on how to approach the issue in order to save the patients life. The main objective of the health expert is to save the life of the patient at all cost, irrespective of beliefs of either the health expert or the patient.

This article talks about the management of mass casualty events through adoption of grander scale. Most health experts are faced with very many cases of emergency that require urgent attention.
