A relativistic finite nucleus calculation using a Dirac optical potential is used to investigate the importance of final state interactions (FSI) at large momentum transfers in inclusive quasielastic electronuclear reactions. The optical potential is derived from first-order multiple scattering theory and then is used to calculate the FSI in a nonspectral Green's function doorway approach. At intermediate momentum transfers excellent predictions of the quasielastic [sup 56]Fe([ital e],[ital e][prime]) experimental data for the longitudinal response function are obtained. In comparisons with recent measurements at [vert bar][ital [rvec q]][vert bar]=1.14 GeV/[ital c] the theoretical calculations of [ital R][sub [ital L]] give good agreement for the quasielastic peak shape and amplitude, but place the position of the peak at an energy transfer of about 40 MeV higher than the data.
