參考: The Washington Manual of Endocrinology Subspecialty Consult
1. Bicarbonate should not be routinely administered to patients in DKA unless
the serum pH is < 7.0 or the patient had life-threatening hyperkalemia
2. Do not decrease or discontinue the insulin infusion when glucose levels
approach the normal range.
3. Patient recovering from DKA may develop a transient non-anion gap
hyperchloremic metabolic acidosis that occurs due to urinary loss of
"potential bicarbonate" in the form of ketoanions and their replacement by
chloride ions from IV fluids. This non-anion-gap acidosis is transient and
has not been shown to be clinically significant except in renal failure.
治療DKA，要monitor"酸"，理論上，應該要看AG的變化....
題目少了Cl-, 因此，無從得知是怎麼酸法。
(舉例，若一開始直接打鹼，雖然pH會往正常跑，但只是把酸鹼狀態變成了
"mixed AG acidosis and metabolic alkalosis")
治療"酸"，大多都是治underlying，很少是直接補鹼的(paradoxical intracellular
acidosis)。
看起來，我會選擇half saline + KCl + RI + D5W....

DKA處理的principle，我是根據2004 ADA的guideline來處理的
請上pubmed找 "Hyperglycemic crises"相關的文章應該可以找到
簡單講幾個原則
1. Insulin要給到ABG已經不酸了，也就是ketoacidosis已經correct
如果glucose已經回到正常範圍，請用兩條以上的IV line
一條可調整insulin，一條keep sugar，或者給病人feeding
2.Sodium要特別注意，記得要先算出Corrected Na
病人來的時候可能測得的Na在normal range，但是correct後反而是hypernatremia
Na高的時候請用HNS
3.Potassium的補充應該不用講了吧
4.Bicarbonate的給予只有在severe acidosis: PH<7.0在給
針對你的問題，我的答案是A
