In context to what you're responding to I must assume, anyway, I'm pretty sure that between the time of requesting your lawyer and that lawyer appearing to advise you then you keep your mouth shut. Refuse to answer any questions until your lawyer is there to advise you. Once the lawyer is present and questioning resumes, you may be advised to invoke the fifth.

Nope, once you have requested a lawyer to be present they cannot question you until you get one (or they get one for you). Of course they never actually go get a lawyer because it's expensive and any lawyer will just instruct you not to answer any questions anyways.
