Calculate with Confidence
Morris · 8th Edition
Complete chapter-by-chapter study guide aligned with Calculate with Confidence (8th Edition). Includes summaries, learning objectives, and NCLEX-style practice questions for all 24 chapters.
Overview
A single dosage error can harm a patient, which is why Calculate with Confidence (8th Edition) is a rite of passage in nursing school — and this study guide follows its workbook structure chapter for chapter so the math finally clicks. It tracks the 8th Edition through its five units, from the math review that rebuilds your foundation, through systems of measurement, methods of administration and calculation, oral and parenteral dosage forms with insulin and pediatric dosing, and finally intravenous, heparin, and critical care calculations. For each of the 24 chapters you get a plain-English summary of the method, the chapter's learning objectives stated up front, and NCLEX-style practice problems with a full worked rationale for every answer, so you see each step rather than just a final number. You will drill the three calculation methods — ratio and proportion, the formula method, and dimensional analysis — then apply them to reading medication labels, calculating oral and parenteral doses, reconstituting solutions, drawing up insulin, setting IV flow rates, titrating heparin, and computing weight-based pediatric doses. Because the guide preserves the Morris organization, your practice matches the course, and the build from basic math to high-stakes critical care calculations lets you gain confidence before the numbers get hard. Whether you are preparing for a dosage-calculation proficiency exam, reviewing before medication administration in clinical, or shoring up the pharmacology math that runs through the NCLEX, each rationale reinforces safe, careful, double-checked calculation. It is printable and made to be worked by hand, so you can practice setting up problems the way you will on a timed exam. Use it to make dosage math a strength instead of a fear. Original, independently written, and not affiliated with the publisher.
Aligned with dosage-calculation proficiency exams and written in an NCLEX-RN style, the practice problems mirror how medication math is tested on course competency exams and the licensure exam.

Does this match the 8th Edition specifically?
Yes — it is built around the 8th Edition and its 24 chapters across five units. Earlier editions teach the same three calculation methods, though some chapters were reordered or expanded in this edition.
Which calculation method does this use?
It practices all three the book teaches — ratio and proportion, the formula method, and dimensional analysis — so you can use whichever your program requires and check your work with a second method.
Will it match my edition?
This guide is built around the 8th Edition. If your class uses a different edition, chapter numbering may shift slightly, but the topics and learning objectives are usually unchanged.
Do I still need the textbook?
The study guide is a companion, not a replacement — it helps you study efficiently and review fast, but you'll still want the textbook for full depth and any assigned readings. You can buy new, rent, or find a used copy through the price links on this page.
