Summary

Arm yourself with the knowledge and skills to succeed in today's challenging health care environment. Allow Math and Meds for Nurses to equip you with the tools to understand calculation through utilization of the three major methods: formula, ratio & proportion, and dimensional analysis. The second edition covers a breadth of dosage calculation topics, from measuring systems to intravenous medications. Special VIP (very important principle) boxes also teach important safety consideration such as prevention of medication errors.
