Chronic Kidney Disease (CKD) is a disease that requires continuous and specialized medical support in clinical settings due to the large number of patients and the high risk of severity. The "Certified Chronic Kidney Disease Care Instructor" is attracting attention as a core qualification in this field. This problem collection has been created as a test preparation problem set (300 questions in total) corresponding to the Certified Chronic Kidney Disease Care Instructor certification exam. It covers the basic knowledge of CKD, dietary and drug therapy, patient guidance, and collaboration with multiple professionals, focusing on areas that are likely to be tested. Rather than simply memorizing knowledge, it emphasizes the perspective of "what kind of judgments and support are required as a care instructor," and is structured with the aim of balancing practical work and the exam. ⸻ Contents of this book • Definition, pathology, and severity classification of Chronic Kidney Disease (CKD) • Renal function evaluation (eGFR, urine tests, imaging tests) • Hypertension and Diabetic Kidney Disease (DKD) • Dietary therapy and nutritional management • Drug therapy (RAS inhibitors, SGLT2 inhibitors, etc.) • Complications associated with CKD (anemia, CKD-MBD, etc.) • Elderly CKD, dialysis, and kidney transplantation • Patient education and behavior change support • Multidisciplinary collaboration and the role of care instructors While considering the scope of the exam, it focuses on points that are often difficult to understand. ⸻ Features • Sufficient practice with a total of 300 questions • Problem design prioritizing frequently tested themes • Self-study support with answers and explanations • Considers the perspectives of medical professionals (nurses, registered dietitians, pharmacists, etc.) • Can be used widely, from knowledge confirmation to last-minute preparation
