Missed it by that much!:doh:
Take the railroad tracks (Captains Bars and) rotate them 90 degs. to the right so that the bars are parallel with the bottom of the the collar. Rotate the caduceus (branch insignia which BTW should have an N in the middle of it for Nurse
Nurses Corps Insignia) 90 degs to the left so it points to the railroad tracks.
This is a picture of 2LT rank without out the branch insignia but just replace rank on the left hand side with the branch and you get the idea.
