Known for its exclusive coverage of the ratio and proportion method, this student-friendly text/workbook presents clear, step-by-step explanations and examples of how to perform drug calculations. Problems in each section progress from simple to complex, and an Answer Key offers proofs that show how to work out each step of the problem and verify the answer. Worksheets in every chapter provide a series of practice problems to reinforce and evaluate learning, now with multiple-choice questions that mimic the NCLEX exam. Full-colour drug labels and equipment illustrations familiarize students with everything they'll encounter in practice, and Clinical Alerts emphasize critical dosage and calculation information. A companion CD-ROM provides additional practice problems. Plus, a new multiple-choice final exam has been added in addition to the original short-answer final exam.
