Isotretinoin is used to treat severe cystic acne. It is a teratogen. Can cause multiple severe birth defects. Contraception is mandatory. RXR is a retinoid X receptor.


the question was very poorly worded in my opinion, anybody else agree?

niboonsh  yea it was a dumbass question, whoever is writing these questions is undoubtedly a crazy genius but homeboy (or homegirl...homeperson?) needs a few grammar lessons. +1  
yex  I agree. We know that it is a teratogen, but how does that question directs you to think about teratogenic effects instead of something physiologic? +2  
dr_jan_itor  The questions in the NBMEs by default are reject questions. So highly selective to be awful questsions. I am recieving regular heads up that the stems on the real thing lately are like 10-12 lines long. So these questions are not anywhere near like the test. NBME has f'd us good for this particular round of practice forms. +
