A sexually active 23 year old woman presents with dysuria, hematuria, and frequency. What is the first step in her assessment?

Choice A rationale While a pregnancy test is important in a sexually active woman presenting with urinary symptoms to rule out ectopic pregnancy or potential teratogenic antibiotic exposure, the initial step must be to gather comprehensive data. A pregnancy test is a diagnostic tool, and its necessity follows the initial data collection for context. Choice B rationale A thorough history and physical examination is the fundamental first step in evaluating any patient, regardless of the chief complaint. This process allows the healthcare provider to gather subjective and objective data, assess risk factors, narrow the differential diagnosis for the dysuria, hematuria, and frequency, and guide appropriate diagnostic testing, such as a urine sample. Choice C rationale A urine culture is a specific diagnostic test used to identify the causative organism in a suspected urinary tract infection. Although a urine sample collection will likely follow the initial assessment, ordering the culture before a thorough history and physical is premature and does not follow the standard, systematic approach to patient care. Choice D rationale Starting empiric antibiotics without a thorough assessment and potential diagnostic confirmation is poor medical practice. Although the symptoms strongly suggest a urinary tract infection, a course of antibiotics should only be initiated after a history and physical and, ideally, after obtaining a urine sample for testing to ensure appropriate, targeted therapy. —.
