Pleаse reаd the clinicаl scenariо, and then answer the 3 questiоns that fоllow to become familiar with the traditional NCLEX question format. Bear Grylls is a 35-year-old male who just spent a week camping in the mountains on a lake. He was not ill at all on the trip, but it seemed like he developed a severe watery diarrhea as soon as he came back. He does not think he contracted it on the trip because “all I ate was prepackaged food, and the only water I drank was fresh mountain lake water.” He appeared to have a moment of realization when you asked him how he treated his water before he used it. He informs you that he did not purify or even filter the water, because he thought that mountain lakes and streams were inherently pure. 1. What are potential causes of Bear’s diarrhea? [1] A. Shigellosis B. Giardiasis C. Pseudomembranous colitis 2. A stool culture is taken, and protozoa are noted upon microscopic examination. Which of the following microbes is the probable cause of Bear’s diarrhea? [2] A. Shigella B. Clostridium difficile C. Giardia lamblia 3. Bear Grylls tells you that he should have known better than to drink untreated lake water. He had always heard that mountain streams were fresh. He then asks you to tell him why the lake water caused his diarrhea. What is the most likely source of this protozoan in lake water? [3] A. Since the human GI tract is used to chlorinated water, it does not have the capacity to deal with foreign organisms. B. Stagnant water sources are literal cest-pools for microorganisms, and any outdoor water source should be suspected. C. Some protozoa are found in the GI tracts of many animals, and their stool often ends up in lakes and streams.
