Calculation of Drug Dosages: A Work Text
Ogden, Fluharty · 12th Edition
Complete chapter-by-chapter study guide aligned with Calculation of Drug Dosages: A Work Text (12th Edition). Includes summaries, learning objectives, and NCLEX-style practice questions for all 19 chapters.
Overview
Dosage calculation is where a lot of nursing students lose points they never needed to lose, and this study guide is built to make sure that is not you. It follows Ogden and Fluharty's Calculation of Drug Dosages: A Work Text (12th Edition) chapter for chapter, so you review in the same order the work text teaches, starting with the math review of fractions, decimals, percents, ratios, and proportions before you ever touch a live drug order. For each of the 19 chapters you get a plain-English summary of the key concepts, the chapter's learning objectives laid out up front so you know exactly what to master, and a bank of NCLEX-style practice questions with a full rationale for every answer, so you learn why a setup works and not just what number to write down. You will work through metric and household measurements, safe medication administration, reading medication labels and prescriber orders, and then the calculation chapters themselves: oral and parenteral dosages, dosages measured in units, reconstitution, intravenous flow rates, critical care drips, and pediatric and obstetric dosages. Every section mirrors the 12th Edition's numbering and its Part structure, so you can jump straight to the topic your instructor assigned and check your work against the same method the book uses. Whether you are drilling before a dosage-calculation competency exam, rebuilding confidence after a rough quiz, or reviewing the whole sequence before the NCLEX, this printable companion is something you can highlight, annotate, and keep for the rest of your program. It keeps the focus on the small, repeatable habits, labeling units, canceling, and double-checking, that turn calculation from a source of anxiety into easy points. Original, independently written, and not affiliated with the publisher.
Built for dosage-calculation competency exams and written in an NCLEX-RN style, with worked practice questions and rationales that mirror how medication math is tested in course check-offs and on the licensure exam.
