The grid is nothing more then simply dividing one of the blank Kardex pages into 12 seperate squares. In the top left square you write you mneumonice for entering the room. Going to the right the next square you write the mneumonic for 20 minutes checks H,I,D,S is sufficient for the 20 minute checks. H is hydration status, I is Intake and Output, D is Drip rate verified, S is Site check (IV). The next grid is the VS grid, you write the VS's you are assigned and you highlight it on the Kardex and the PCS recording form as a checks and balance system. The next block you write the mneumonic for Mobility. These top four left to right boxes are areas that will be assigned on every patient. The remaining blocks will be filled with the areas of care you will be assigned for that patient. This system worked very well for me. I just checked it off as I completed it. The grid will keep you on track and helps keep you from making mistakes. Your mnuemonics are you critical elements for each area of care. The best thing for you to do is pay a little extra money to attend a workshop. They will explain it and show it to you. Not just the grid, but what to expect during the entire test. I had to test twice and that extra $2000 hurt. Greg
