Problem: The nurse understands that metabolic acidosis develops in kidney failure as result of?
1. Inability of the tubules to secrete hydrogen ions and conserve bicarbonate
2. Inability of the renal tubules to reabsorb water; to dilute the acid contents of the blood
3. Impared glomerular filtration; causing retention of sodium and metabolic waste products
4. Depressed respiratoryrate by metabolic wastes; causing carbon dioxide retention
