Umm, that's an odd interview for a job. Levophed, Dopamine, Dobutamine, heparin, beta blockers, ACEIs, ARIIbs, calcium channel blockers, Nipride, Cardene, propofol, precedex, various electrolyte boluses, etc. Pretty much everything is used in the unit drug wise.
As far as the swan....know your normals. Know your abnormals and what they mean. Know how to shoot your numbers (if you don't have CCO swans).
You might want to review from your medsurg books the sections about recovering hearts, lungs, etc. Care of the IABP, Vents, A-lines, Swans.
Good luck on your interview!
