An inventive advisor across many professional fields, author Djanie here focuses on assisting those studying and practicing nursing. His method involves a simple mathematical formula. He begins with an example asking how many cents are in two dollars, something that any reader can grasp. In each case, the basic unit sought must always be placed in the numerator position, then treated with the appropriate arithmetical steps of multiplication and division to arrive at the correct solution.

This straightforward process, illustrated numerous times throughout Djanie's guide, can be used in a range of medical contexts. If a doctor orders 250 mg of a medication, for instance, and each recommended tablet contains 0.5 grams of the substance required, the nurse would work from their given knowledge that one gram equals 1,000 mg, applying the formula accordingly. The data offered becomes increasingly complex, amplified by a listing of "Medical Administration Terminologies and Standard Tables": "H" or "hr" stands for the Latin "hora" meaning "hour'; "PO" or "per os" means "by mouth."

Djanie's text offers helpful multiple-choice tests focusing on the administration of medications. The author, who also counsels through spheres such as increasing income through various means, devised this practical "one touch" formula when faced with medical questions on an unexpected exam at a hospital. Failure to pass the exam would have been ruinous, so he developed this useful method and later used it successfully for every subsequent nursing exam. Though his didactic treatise concentrates on the formulaic aspect, it also evokes images of the complicated, often on-the-spot knowledge and decision-making required by nurses and medical personnel as they administer needed help quickly and with total accuracy. His method provides crucial instruction to nursing staff and can potentially save lives.
