This assignment is a comprehensive analysis of chronic renal failure, focusing on a 55-year-old patient, Melanie Johnson. The paper begins with an overview of renal anatomy and physiology, followed by an in-depth exploration of the pathophysiology of chronic renal failure, including risk factors like age, hypertension, and anemia, as well as potential complications and treatment options. The assignment differentiates between acute and chronic renal failure and discusses renal replacement therapy, specifically hemodialysis, including the creation of an AV fistula. Furthermore, it examines two medications, Valsartan and Eprex, detailing their uses, side effects, and crucial nursing considerations for Melanie. The paper also explains the significance of GFR and Hb blood tests in diagnosing and monitoring the condition, concluding with a discussion on the teach-back method for patient education, particularly regarding dietary fluid management.
