I've got a book called Memory Notebook of Nursing: Pharmacology & Diagnostics
by Tom Gaglione, JoAnn Zerwekh, Jo Carol Claborn and C. J. Miller (Nursing Educational Consultants) (about $22). This group does NCLEX review courses and this book which is part of a series of 3 is a compilation of drawings and cartoons specifically about drugs and their side effects or actions and lab tests. They use mneumonics in some cases, clever associations or cartoons to help you remember the important concepts. For example, on the page for NSAIDS (pg. 73) it has a cartoon of a gym with a sign that says:
No Pain, No Flame. . .And
No Heat When We Meet.
Analgesic, Anti-inflammatory Antipyretic
There is a tablet of ibuprofen lifting an 800mg weight saying "One, two, three, four. . .oof! That's all I can do in one day!" On the other side of the page is a tablet of Naproxen lifting a 500mg weight saying "Onnnnne, twooooooo, That's all I can do in one day!" These, of course, are illustrating the maximum doses of these two drugs. Two guys in the lower part of the page are talking. One says, "Watch out for: GI distress, dizziness, rash, heartburn, & occult blood loss." And, the other replies, "Okay, 'nuff said about NSAID's!"
Considering that most of this stuff is pretty cut and dry they've worked hard to try to spice it up. I just happened to cite one example that stuck out at me. The last part of the book focuses on labwork and collection of specimens. Much of this probably translates better when it is presented in their seminars. The main point, however, is that they hit on the major drugs and drug classifications and what you need to know about them.
The book is 126 pages.
