Certified Nephrology Nurse Certification (CNN) Practice Exam

The acronym "CKD" stands for "Chronic Kidney Disease." This term is widely used in nephrology to describe a long-term condition where the kidneys progressively lose their ability to function effectively. Chronic kidney disease can be classified into five stages based on the severity and progression of kidney damage, which is particularly significant for identifying patient management and treatment strategies.

This condition encompasses a variety of pathophysiological processes that can lead to kidney damage over time, often as a result of factors such as diabetes mellitus and hypertension. Understanding CKD is crucial for healthcare providers as it allows for early intervention, better management of complications, and education regarding lifestyle changes that patients can make to slow the progression of the disease. In contrast, the other options do not accurately represent established medical terminology used in nephrology and are less recognized in the context of kidney health.
