    You are doing a pre-op for a pt who will be coming in next Tuesday for spinal surgery. This patient has a history of HTN and wants to know when he should stop taking his medication for the surgery. What do you say?

    • Take your last dose the night before since you must remain NPO for 8 hours prior to surgery.

    • Take a double dose of medication the night before, this way it will last until surgery.
