Book excerpt: The most effective study guide for the Critical Care Nursing Certification Exam—now with all- new artwork! Critical Care Nursing Certification Review is a comprehensive, single-source review that covers everything you need to know to excel on the examination administered by the American Association of Critical Care Nurses (AACN).

Following the CCRN blueprint, coverage of each subject is weighted to reflect its level of importance on the actual exam.

Chapters cover all the systems and topics you need to master, including: •Cardiovascular •Pulmonary •Endocrine •Immunology and Hematology •Neurology •Gastroenterology •Renal •Multi-organ Problems •Professionalism, Ethics, and Synergy •Behavior
