Write answer in between .Q:A 26-year-old woman presents to the emergency department with fever, chills, lower quadrant abdominal pain, and urinary frequency for the past week. Her vital signs include temperature 38.9C 102.0F, pulse 110min, respirations 16min, and blood pressure 12278 mm Hg. Physical examination is unremarkable. Urinalysis reveals polymorphonuclear leukocytes PMNs 10 cellsHPF and the presence of bacteria 105 CFUmL. Which of the following is correct concerning the most likely microorganism responsible for this patients condition?? A: Nonmotile, pleomorphic rod-shaped, gram-negative bacilli , B: Pear-shaped motile protozoa, C: Gram-negative rod-shaped bacilli, D: Gram-positive cocci that grow in clusters, E: Gram-positive cocci that grow in chains,  <response>: This is a clinical vignette describing a 26-year-old woman with symptoms and findings consistent with an acute urinary tract infection UTI. The key findings are fever, chills, lower abdominal pain, urinary frequency, pyuria 10 PMNsHPF on urinalysis, and bacteriuria 105 CFUmL. Based on the patients age, gender, and localization of symptoms to the lower urinary tract, the most likely diagnosis is acute cystitis. The most common cause of acute cystitis is uropathogenic Escherichia coli, a gram-negative rod-shaped bacterium. The answer choices describe different types of bacteria. Choice A describes Proteus species, which can cause UTIs but is less likely than E. coli. Choice B describes a protozoan parasite not typically found in urine. Choices D and E describe gram-positive cocci in clusters or chains, characteristic of Staphylococcus and Streptococcus species, which are uncommon causes of uncomplicated cystitis.Therefore, based on the clinical presentation and microbiologic findings, the most likely organism is choice C, gram-negative rod-shaped bacteria, consistent with E. coli.C: Gram-negative rod-shaped bacilli
