In a reproductive-age woman with dysuria and a new sexual partner, which single initial test is most important to order?

• A. Pregnancy test
• B. Urinalysis
• C. Chlamydia trachomatis screen
• D. Neisseria gonorrhea screen

Answer: (A)

The most important first step is to determine whether the patient is pregnant. In a reproductive-age woman with dysuria and a new sexual partner, pregnancy status directly shapes what you can safely do next. A pregnancy test is quick, inexpensive, and noninvasive, and its result changes management right away: it guides safe antibiotic choices, avoids giving teratogenic or contraindicated medications, and informs whether further obstetric evaluation or special imaging is needed. While UA and STI screening provide useful information, they do not influence immediate safety and treatment decisions as much as confirming pregnancy status.
