Chronic Kidney Disease (CKD) is a condition that requires continuous and specialized care and support in medical settings due to the large number of patients and the high risk of severe progression. The "Certified CKD Care Manager" is gaining attention as a qualification that plays a central role in this. This problem set has been created as a set of exam preparation questions (300 questions in total) corresponding to the Certified CKD Care Manager certification exam. It is organized around areas that are frequently tested, from basic knowledge of CKD to dietary and drug therapy, patient guidance, and multidisciplinary collaboration. Rather than simply memorizing knowledge, "What kind of judgment and support is required as a care manager?" The content is structured with an emphasis on this perspective, aiming to balance practical application and exam preparation. ⸻ Content Structure of This Book • Definition, pathophysiology, and severity classification of Chronic Kidney Disease (CKD) • Kidney function assessment (eGFR, urinalysis, imaging tests) • Hypertension and Diabetic Kidney Disease (DKD) • Dietary therapy and nutritional management • Pharmacotherapy (RAS inhibitors, SGLT2 inhibitors, etc.) • Complications associated with CKD (anemia, CKD-MBD, etc.) • CKD in the elderly, dialysis, and kidney transplantation • Patient education and behavioral change support • Multidisciplinary collaboration and the role of the care manager While keeping the exam scope in mind, it focuses on points that tend to be ambiguously understood. ⸻ Features • Sufficient practice with a total of 300 questions • Question design prioritizing frequently tested themes • Includes answers and explanations, suitable for self-study • Considers the perspectives of medical professionals (nurses, registered dietitians, pharmacists, etc.) • Can be used for a wide range of purposes, from knowledge confirmation to last-minute preparation
