For each of the following classic clinical presentations of infectious diseases, select the most appropriate first-line targeted antimicrobial therapy.
- A 20-year-old male notes a single, indurated, painless ulcer on his glans penis. He has bilateral rubbery inguinal lymph nodes. Point-of-care darkfield microscopy shows spirochetes.Intramuscular benzathine penicillin G
- A 22-year-old female college student complains of painful urination and increased urinary frequency for two days. She is afebrile and has no costovertebral angle tenderness.Oral nitrofurantoin
- A 54-year-old male develops a 10-cm annular rash with central clearing on his lower extremity two weeks after a camping trip in Connecticut.Oral doxycycline
- A 32-year-old female presents with a profuse, malodorous, yellow-green vaginal discharge and vulvar irritation. Wet mount microscopy reveals motile, flagellated protozoa.Oral metronidazole
Cevap
Primary syphilis matches with intramuscular benzathine penicillin G. Uncomplicated acute cystitis matches with oral nitrofurantoin. Early localized Lyme disease matches with oral doxycycline. Trichomoniasis matches with oral metronidazole.
Each specific clinical scenario presents classic pathognomonic signs of an infectious disease that corresponds directly to a well-established, first-line antimicrobial therapy per current medical guidelines.
