Your question is unclear, do you have a Q dimensional array that you are extracting elements from, or a 1 dimensional array that you are extracting the P^Qth element from? Incidentally you probably should use lower case variables. If it's the first case just use Table arr[[Sequence@@Table[p,{q}]]] will extract the element p,p,...p repeated q times of arr.
