Nursing Research is like a submarine (the researcher), that goes into the sea to find treasures (literature). During the search for treasure, the submarine travels deep into waters finding corals, fish, and even strange creatures. Once, the search is satisfied, the submarines comes back to sea level and starts sorting the treasure. Some of the treasure could be silver or bronze, but the submarine is looking for most value gold. Once, all the gold is in one pile, the submarine will sort the gold by qualitative or qualitative material. Also, if it real gold or plated gold (validity). If the gold obtained is not of satisfaction, the submarine will go back into the deep sea.
