A 94-year-old woman went to her local hospital emergency department in mid-November 2001 complaining of a 5-day history of weakness, fever, nonproductive cough, and generalized myalgia (muscle aches). Otherwise, for a person her age she was fairly healthy, although she did suffer from chronic obstructive pulmonary disease, hypertension, and chronic kidney failure.
On physical examination, her heart rate was above normal and she had a fever of 102.3F (39.1C). The rest of her physical examination was normal. Initial laboratory studies of blood cell count, blood chemistries, and chest X ray were also normal except for the chemical urine testing. This finding along with the fever suggested an infection, so the patient was admitted to the hospital. Samples of blood and urine were sent to the microbiology laboratory and set up appropriately.
The next day, microscopic evaluation of the urine culture revealed rod-shaped bacteria that stained red, and the blood culture revealed rods that stained purple. The liquid blood culture was then transferred to appropriate solid media. This finding in the blood was unusual, so a sample culture was sent to the state health department laboratory. Antibiotic therapy was adjusted, yet the patients condition deteriorated. Her most serious symptoms localized to her chest, and she was transferred to the intensive care unit. Four days after admission, the health department announced that the bacteria found in the patients blood were Bacillus anthracis. She was suffering from inhalation anthrax. Further testing showed these bacteria to be of the same strain that had been involved in the recent bioterrorist attack. Despite treatment, the patient died on the fifth day after admission.

Guidelines
In each Module you are assigned a case study write-up that is due(suggestive date) by the end of Day 3 that constitute 16% of your final grade. Each case write-up is an individual assignment and no collaboration is allowed among students. Cheating of any form or plagiarism will result in receiving zero for the corresponding case write-up and you must address to the best of your abilities what the question is asking for.
All case write-ups must be submitted to Turnitin, which is a built-in feature of the course Canvas site. Study the case study carefully and then proceed to answer the question(s). Try to justify your responses by drawing from the Modules material and be concise and to the point. Your responses should not exceed 350 words, and AI red flag.
The purpose of the Case Write-Ups is to get you acquainted with and internalize the taught concepts, and be able to apply them in order to solve various cases that medical professionals are faced with on an everyday basis.
