Final answer:
The recommended treatment approach for ethylene glycol intoxication in the intrinsic setting is to perform dialysis or use NaHCO3 if the pH is less than 7.2. Intravenous fluids should also be administered.
Step-by-step explanation:
The recommended treatment approach for ethylene glycol intoxication in the intrinsic setting is to perform dialysis or use NaHCO3 if the pH is less than 7.2. This is because ethylene glycol poisoning can lead to metabolic acidosis, primarily due to the accumulation of glycolic acid. Dialysis helps remove the toxic metabolites from the blood, while NaHCO3 can be used to correct the acid-base imbalance. Additionally, administering intravenous fluids is important to maintain hydration and support kidney function.
