The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 39-year-old woman is brought to the emergency department because of fevers, chills, and left lower quadrant pain. Her temperature is 39.1°C (102.3°F), pulse is 126/min, respirations are 28/min, and blood pressure is 80/50 mm Hg. There is blood oozing around the site of a peripheral intravenous line. Pelvic examination shows mucopurulent discharge from the cervical os and left adnexal tenderness. Laboratory studies show: Platelet count 14,200/mm3 Fibrinogen 83 mg/mL (N = 200–430 mg/dL) D-dimer 965 ng/mL (N < 500 ng/mL) When phenol is applied to a sample of the patient's blood at 90°C, a phosphorylated N-acetylglucosamine dimer with 6 fatty acids attached to a polysaccharide side chain is identified. A blood culture is most likely to show which of the following?"   (A) Coagulase-positive, gram-positive cocci forming mauve-colored colonies on methicillin-containing agar   (B) Encapsulated, gram-negative coccobacilli forming grey-colored colonies on charcoal blood agar   (C) Spore-forming, gram-positive bacilli forming yellow colonies on casein agar   (D) Lactose-fermenting, gram-negative rods forming pink colonies on MacConkey agar
