Calculate with Confidence

Calculate with Confidence, 8th Edition, by Deborah C. Morris is a nursing textbook that prepares nursing students and healthcare learners to perform precise clinical math across varied practice settings. The volume builds fundamental mathematical understanding by presenting three primary calculation methods: ratio and proportion, the formula method, and dimensional analysis.

The thematic scope progresses from basic math review to specialized clinical subjects, including pediatric and adult weight-based dosage calculations, fluid administration, and critical care math. Client safety is emphasized throughout the text, with Quality and Safety Education for Nurses (QSEN) principles integrated directly into Unit One Math Review to support error prevention.

To align with modern licensure requirements, this edition introduces five newly added single-episode Next Generation NCLEX (NGN) case studies aimed at strengthening clinical reasoning and judgment. Published by Elsevier Health Sciences, the text was selected for Doody's Core Titles 2024 in Pharmacology.
