Returning to work after Lipo and breast exchange?

Your activity limitations depends on how far out from your procedure you are. I encourage my patients to not lift more than a gallon of milk for 6 weeks after most procedures.  Your breast implant exchange and lipo would be a typical procedure that I recommend light activity for 6 weeks.  My patients who are nurses are encouraged to keep light duty without lifting patients for 6 weeks and wear their compression garments at all times.
After the 6 weeks post-op period, if certain activities cause discomfort I encourage them not to do those activities until they can do so comfortably. 
Each patient is different and some need longer recovery than others.
In your case I would consult your plastic surgeon to discuss your specific post-op plan.

It's best to follow the advice of your surgeon. After breast implant surgery it's strongly recommended to avoid lifting and other strenuous activity for about 4 weeks (at least 2 weeks). Subsequently, you can gradually increase your activity level.Pejman Aflaki, M.D.Johns Hopkins-trained plastic surgeon
