This text is part of the "NCLEX-RN PreTest" package which should help nursing students prepare for their licensing exams. This review book consists of: common medications; lab values; common illnesses in infants, children and adults; and test-taking tips for the written tests in the book. Study outlines by system or by disease state allow students to review the material quickly and comprehensively. Each section is followed by tests and explanations in a unique format: test questions are on the left side of the book and the corresponding explanation is shown on the right side. Students are instructed to use one of the perforated answer sheets to cover the right-hand page as they test themselves; then they are be able to see the correct answer and full rationale when they go through again to grade the exam.
