(b) Failure to Comply With Order.

(ii) An order...prohibiting (the disobedient party)...from introducing evidence of physical or mental condition;

(iii) An order striking out pleadings or parts thereof, or staying further proceedings until the order is obeyed, or dismissing the action or proceeding or any part thereof, or rendering a judgment by default against the disobedient party;

(iv) In lieu of any of the foregoing orders or in addition thereto, an order directing the arrest of any party or agent of a party for disobeying any of such orders except an order to submit to a physical or mental examination.
