I actually had a medical resident who would always just jump in and help- lifiting patients up in bed, placing foley catheters with out even a blink, etc.
It turns out he was a medic in the Army, had the military, "I am here to help," attitude, and the discipline to go along with it. He respected nurses, because in the military, all RNs are officers, and undoubtedly, they ALL outranked him! It was a refreshing change!
So, yes, there are doctors who do help out, and do "nurse things", but I agree, they are few and far between in the real world!
