P(k) and P(q)

If we were calculating a reaction with multiple phases (i.e. solid, liquid, aqueous, gas), will calculating P(q) and P(k) only deal with the gases?

When calculating K(p) and Q(p), solids and liquids(solvents) are not included but both aqueous species and gases are included.

To clarify for both Q (initial conditions) and K (equilibrium conditions): when the compounds are gases use P for partial pressure and when the compounds are in aqueous state use the concentration (brackets). Disregard compounds in solid or liquid phase. Don't use partial pressure and concentration in the same Q/K expression... I don't think we're ever given problems like that.
