In Concepts of Kidney Disease, a core objective is recognizing pathologic processes and complications of CKD progression. As GFR declines below 30 mL/min (stage 4), the kidneys produce less erythropoietin, leading to normocytic normochromic anemia. This causes fatigue. Fluid retention from reduced excretion leads to edema. Other common issues include hyperphosphatemia (not hypophosphatemia), hyperkalemia, and metabolic acidosis. Anemia management often involves ESA therapy like epoetin alfa, with monitoring for iron stores (TSAT, ferritin). Nurses must teach patients about symptom recognition, dietary modifications (e.g., protein, sodium, potassium, phosphorus control), and BP management to slow progression. Preserving residual kidney function through ACE/ARB use (if tolerated), avoiding nephrotoxins (NSAIDs), and lifestyle changes (smoking cessation, exercise) are key interventions. Regular monitoring of labs (CBC, electrolytes, PTH, vitamin D) and staging per KDIGO guidelines helps plan timely modality education. This question tests pathophysiology linkage to clinical presentation, a frequent CNN objective. Early intervention prevents worsening quality of life and cardiovascular complications associated with anemia. Multidisciplinary care involving dietitians and nephrologists is essential for holistic management.
