He says that the week prior he slipped while hiking and scraped his left leg. Over the course of the next week, he noticed redness and swelling of the scraped area and the development of a nodule that eventually ulcerated. On exam, his temperature is 99.5F 37.5C, blood pressure is 13692 mmHg, pulse is 88min, and respirations are 12min. Over his left lateral leg is an erythematous patch with a 2-cm nodule with central ulceration. Staining of a sample from the nodule demonstrates gram-positive organisms that are also weakly acid-fast. Morphologically, the organism appears as branching filaments. Which of the following should be used to treat this infection?? A: Clindamycin, B: Doxycycline, C: Penicillin, D: Streptomycin, E: Trimethoprim-sulfamethoxazole,  <response>: This is a patient with an ulcerating skin lesion after a hiking injury that is showing signs of infection. The description of gram-positive, weakly acid-fast, branching filamentous organisms indicates an infection with Nocardia species. Nocardia is typically treated with trimethoprim-sulfamethoxazole, making choice E the correct answer. Choices A, B, C, and D are incorrect as clindamycin, doxycycline, penicillin, and streptomycin are not first-line agents for treating Nocardia infections.E: Trimethoprim-sulfamethoxazole
