Does anyone know of this type of LPN book?

My sister, who is an LPN, said she remembers looking at some type of practical nursing book at Barnes and Noble a few months back that she thinks would be of great help to me. However, we went there tonight and she didn't see the book she was thinking of. She can't remember the name, but she said they are smaller books (in size) and they are made for practical nursing. She said each book deals with a certain subject like electrolytes, med surg, etc. They are suppose to have just a couple of multiple choice questions on each page to help you study. She can't remember if it is an Nclex-pn review book, or what. However, she said they only deal with one subject area in each book. Does this sound like a book any of you might recognize? If so, please let me know what they are called or even the author. Thanks a bunch!
