If a vacuum tube has not been what, the blood will what and the what will be incomplete?

sealed, dry, record

opened, spill, process

mixed, invert, clot

When a vacuum tube is not properly mixed and inverted after drawing blood, the anticoagulant in the tube will not be distributed evenly and the blood will not be prevented from clotting. This can lead to an incomplete sample for the desired analysis. Option A is incorrect because the blood should not be dry when drawn. Option B does not mention the importance of mixing and inverting, making it incorrect. While option D touches on preventing coagulation, it does not mention the need for proper mixing and inversion.
