No offense meant, but if a cordis is in a patient that is even semi-stable and on the floor, then it needs to be D/C'd ASAP. There is no indication for these in stable patients. If they need a central line, then fine, insert a TLC or QLC over the wire and pull the cordis regardless.
The McGuffey Readers were designed to be used by frontier Americans, who often did not have access to a full time teacher. Because of this, the books are very self supporting, and, to a great extent allow the student to teach themselves, once they have learned to read. Will run on any computer.
It is estimated that at least 120 million copies of McGuffey's Readers were sold between 1836 and 1960, placing its sales in a category with the Bible and Webster's Dictionary. Since 1961 they have continued to sell at a rate of some 30,000 copies a year.
