HESI Chronic Kidney Disease Case Study Practice Test

In CKD, limiting sodium helps control fluid balance and blood pressure because the kidneys struggle to excrete excess sodium. Reducing sodium intake decreases fluid retention, lowers extracellular fluid volume, and reduces cardiovascular strain, making it easier to manage edema and hypertension who often accompany CKD. A typical goal is about 2 to 3 grams of sodium per day, which aligns with keeping fluid under control while still being realistic for long-term adherence. Much lower restrictions (around half a gram daily) are usually too restrictive for most people and hard to maintain, while no restriction can lead to worsening edema and high blood pressure. A higher intake would similarly worsen fluid overload and BP control. Individual plans may adjust this target, but 2–3 grams daily is the common benchmark.
