Just make sure you have an organizied search pattern, and comment on normal and abnormal as you go. Everybody has a differenct search pattern, but make sure that yours covers the ENTIRE film. Even if you miss something, you will impress with that kind of approach - just dont miss the bowling ball in the chest and you'll be fine. Good luck!
Don't go too much into describing normals, keep it to the pertinent issues:
- ET tube position
- NG/OG tube position
- chest tubes/mediastinal drains
- pneumothorax yes/no
- lobar collapse ?
- briefly compare to last prior.

Don't try to hunt down small effusions on the half-erect portable films.
