Rationale: The correct answer is C: 'The stomach contents and air must be drained first.' Before starting feedings through a gastrostomy tube, it is essential to drain the stomach contents and air. This process helps prevent complications and ensures the proper functioning of the tube after placement. Choice A is incorrect because initiating feedings within 5 to 7 days may lead to complications if the stomach is not adequately prepared. Choice B is incorrect as feeding should not begin immediately to allow for proper preparation of the tube and the stomach. Choice D is incorrect because although incision healing is important, draining the stomach contents and air is a more immediate concern to prevent complications.
