ed, as usual, is right.
i am currently licensed for "medicine and surgery". it says so right on my license
we've admitted 28 yr olds to the ward before. i just took care of a 29 year old in a top ten children's hospital PICU. we have several CFers in their 20's as well.
not to mention-- a medical license is a medical license, regardless of residency/fellowship/etc. The army routinely sends pediatricians, pediatric subspecialists (even neonatologists
) to iraq/afghanistan as general medical (read: basic FP urgent care-ish stuff) officers. Not the best model, i agree (54 yo with chest pain? ekg, MONA . . then. . . ummmm . . .) but for most things it works-- mainly because of basic medical knowledge and augmentation with references (and google if ya got internet access).
