Match each clinical presentation of a common infectious disease with the most appropriate first-line pharmacotherapy.
- A 24-year-old woman with dysuria, urinary frequency, and suprapubic pain; urinalysis reveals nitrites and leukocyte esterase without systemic symptoms.Oral nitrofurantoin
- A 30-year-old man with an expanding, painless, target-like erythematous rash on his leg after a camping trip in Massachusetts.Oral doxycycline
- A 19-year-old man with a painless, 1.5-cm indurated genital ulcer and bilateral firm, non-tender inguinal lymphadenopathy.Intramuscular benzathine penicillin G
- A 22-year-old woman with exudative pharyngitis, fever, tender anterior cervical adenopathy, absence of cough, and a positive rapid antigen detection test.Oral amoxicillin
Cevap
The correct pairings match uncomplicated cystitis with oral nitrofurantoin, early localized Lyme disease with oral doxycycline, primary syphilis with intramuscular benzathine penicillin G, and confirmed Group A streptococcal pharyngitis with oral amoxicillin.
Each clinical scenario represents a highly classic, uncomplicated presentation of a common infection for which there is a clear, guideline-directed first-line therapy. Using narrow-spectrum agents ensures efficacy while adhering to strict antibiotic stewardship principles.
