Delta H and q are the same assuming constant PRESSURE. Delta E is reserved for internal energy, and is the sum of the heat at constant pressure, hence we use q.....and the work done. For your purposes, use delta H and q interchangeably. For a nice discussion on this, Brown and LeMay General text does a nice job, as well as David Klein Organic Chemistry.

Hope this helps.
