What is a key focus in the treatment of renal failure?

• A. Focus on BP control alone
• B. Aggressive diuresis without monitoring labs
• C. Carefully monitor I&O, electrolytes, and watch for signs of CHF
• D. Frequent antibiotic therapy

Answer: (C)

Managing renal failure centers on maintaining fluid and electrolyte balance and watching for complications from fluid overload. The key is to carefully track intake and output to guide fluid therapy and to monitor electrolytes regularly, since the kidneys’ inability to regulate fluids and ions can quickly lead to dangerous disturbances like hyperkalemia, acidosis, or volume mismanagement. Frequent labs reveal trends in electrolytes, BUN, and creatinine, helping to tailor treatments and prevent complications. Because excess fluid can push the heart toward congestive failure, clinicians stay alert for signs such as weight gain, edema, crackles in the lungs, and shortness of breath, adjusting fluids and therapies accordingly. While blood pressure control matters, it doesn’t replace the need to vigilantly monitor I&O, electrolytes, and cardiac signs. Aggressive diuresis without lab supervision can cause electrolyte shifts or hypoperfusion, and antibiotic therapy is not a universal focus unless an infection is present.
