Nursing-focused and easy-to-read, this handbook delivers all of the information you need to understand how tests work, interpret their results, and provide quality patient care—pre-test, intra-test, and post-test. The 5th Edition is completely updated and revised to reflect the most current information. You'll find new discussions of age-specific concerns in the front matter, along with 'image gently' pediatric guidelines and move-to-track/limit dosages in adults, standardized terminology in the 'Indications' and 'Results' sections, as well as more nursing diagnoses terminology in the 'Nursing Implications and Procedure' sections, SI units in the 'Laboratory Critical Values' sections, and much more. As a bonus, you'll find a wealth of learning activities and reference tools online at DavisPlus, including a student workbook, interactive exercises, monograph search, laboratory and diagnostic critical findings, and much more.
