✍️ Sample NBME Questions & Answers
1. The cloacal membrane divides into the urogenital membrane and anal membrane at approximately which embryonic week?
The urorectal septum divides the cloaca into the urogenital sinus and anorectal canal by the end of the 7th week, separating the urogenital and anal membranes.
2. During eukaryotic DNA replication, which enzyme complex synthesizes the RNA primer at origins of replication?
DNA polymerase alpha associates with primase to synthesize short RNA primers that provide the 3'-OH needed by replicative DNA polymerases.
3. A 36-year-old woman with hypertension well-controlled on lisinopril asks about contraception. Which method is CONTRAINDICATED in this patient?
Combined oral contraceptives are contraindicated in women with hypertension due to increased risk of stroke and myocardial infarction, especially over age 35.
4. A disease has a prevalence of 50 per 1,000 and an incidence of 10 per 1,000 per year. What is the average disease duration?
Using the steady-state formula Prevalence = Incidence × Duration: Duration = 50/10 = 5 years.
5. A 40-year-old woman with lupus has been on hydroxychloroquine for 5 years. Which monitoring study is most important to perform annually?
Hydroxychloroquine can cause irreversible retinal toxicity that is dose- and duration-dependent, requiring annual ophthalmologic screening after 5 years.
