The administration of drug treatments in hospitals has become increasingly complex. It sometimes involves potent drugs that may be fatal if administered incorrectly. The ability to perform drug calculations accurately is therefore paramount to prevent placing patients at risk. Drug Calculations for Nurses: A Step-by-Step Approach teaches healthcare professionals how to perform drug calculations with confidence and competence. It provides step-by-step guidance to carry out accurate drug calculations, with units and drug strengths clearly explained. This bestselling pocket-size book begins with the basic mathematical skills required to perform calculations, including tips on estimating answers. It then covers drug strengths and concentrations, dosage calculations, IV infusion therapies, and pharmacodynamics and pharmacokinetics. Two separate chapters focus on children and the elderly, addressing specific challenges encountered in these populations. Helpful worked examples, key points, and objectives are included in every chapter. Useful tables with common prescription ab
eviations, estimation of renal function, and body surface area estimates are easily accessible through the appendices. This new edition comes with an online pre-test enabling readers to benchmark their knowledge. Specific weaknesses can then be identified and addressed in the printed book. Also included is a revision test that allows readers to assess their ability to perform drug calculations after completing the book.
