An impulse approximation with relativistic corrections is derived to incorporate the fact that each constituent nucleon of the target nucleus is moving in an average local central potential generated by the other nucleons. The constraint imposed by current conservation is described. An application of the resultant impulse approximation to reanalyze symmetry tests in the $A=12\mathrm{}$ nuclei induces a few subtle changes but does not upset the standard interpretation of these experimental results.
