We are using a POSCAR file with a single atom. Sufficiently large lattice parameters are selected so that no (significant) interactions between atoms in neighbouring cells is present.

For atoms or molecules a single k point is sufficient. When more k-points are used only the interaction between atoms (which should be zero) is described more accurately.
