Just took it today:
no calculations. I had no questions on developmental milestones, surprisingly. I had lots and lots of ID questions, four or five color pictures of exanthems or anomalies (very common ones, easy answers).
I had over 6 questions on "kid w/ limp" or kid w/ joint pain .. etc. About five questions on hematology at the end that dealt w/ anemia -- know the different anemias in kids! post-viral syndome questions .. about three.
Acne tx, not very many questions (if at all) on drug side effects. Oh, RTA .. just be able to recognize it by electrolyte numbers. Rickets ..
Pre-test, FA for Wards (peds section), and BP were just fine for this exam. Best of luck!
