In this work the hydrodynamic approximations in the cold nuclear matter are analyzed and compared to the zero sound solution in the long wavelength limit. It is shown that the hydrodynamical hierarchy can reasonably approximate the zero sound solution only in the case of strongly repulsive interaction parameters. When the zero sound mode is damped, the hydrodynamical approximations beyond the first sound are shown to have no physical meaning.
