What are the goals of electrolyte management in PD?

• A. Increase phosphate with high phosphorus diet
• B. Ignore metabolic acidosis
• C. Minimize protein intake
• D. Maintain phosphate/calcium balance, correct metabolic acidosis, and ensure adequate protein intake

Answer: (D)

Managing minerals, acid-base status, and nutrition is central to PD electrolyte management. The goal is to keep phosphate and calcium in balance because phosphate tends to rise in kidney failure and can bind calcium, fueling bone disease and vascular calcifications; dialysis helps remove phosphate and medications or dietary adjustments manage calcium balance to avoid too much calcium or too little. Correcting metabolic acidosis is another key aim, since PD solutions provide bicarbonate and maintaining a normal acid-base state supports protein synthesis, reduces protein breakdown, and generally improves energy and well-being. Ensuring adequate protein intake is essential because dialysate losses can lead to protein wasting; enough protein helps preserve muscle, immune function, and overall nutritional status. The other options would worsen outcomes: increasing phosphate intake worsens mineral balance, ignoring acidosis allows decline in health, and reducing protein intake worsens nutrition and recovery.
