Summary

The Dosage Calculations text has set the standard in teaching dosage c alculation and now, for the first time, a ratio and proportion method is available. It incorporates the strengths of the original, clear wri ting style, extensive math review, beginning to advanced concepts pres ented in manageable segments, and hundreds of practice problems. This edition includes actual drug labels, equipment photos, and illustratio ns to help students learn. The ratio and proportion edition is a compr ehensive learning system that includes an interactive CD-ROM. The CD-R OM encourages self-paced learning in a low anxiety environment that re inforces the classroom material.
