[{'content': 'Why is citrate phosphate dextrose (CPD) is better than acid citrate dextrose (ACD) for storage of blood? \nSelect and explain. \nA. Because it is less acidic, B. Improves oxygen transpo, C. Hypeonicity of blood, D. More citrate ions', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Citrate dextrose phosphate adenine (CDPA-1) helps in improving ATP synthesis during storage, thus increasing the shelf-life of storage up to35 days. Disadvantage of CDPA-1:Increases uric acid stone formation. Citrate phosphate dextroseImproves oxygen transpo Shelf life of the blood after adding above chemicals: - Acid citrate dextrose -> 21 days Citrate phosphate Dextrose -> 21 days Citrate phosphate Dextrose Adenine -> 35 days Saline Adenine Glucose Mannitol -> 42 days.', 'role': 'assistant'}]
