25.有關TPN nitrogen balance之敘述，下列何者錯誤？
(A)對於negative nitrogen balance之病人，可以試著增加calories及protein的攝取量
(B)nitrogen balance＝nitrogen intake－nitrogen losses
(C)nitrogen balance之計算需要收集24小時之尿液
(D)經由糞便、呼吸及皮膚排出之氮無法計算，故使用估計值每天0.5～1.8 g

補充--1克氮=6.25克蛋白質
TPN中加蛋白質的功能 : 提供組織修復所需要的氮 提供熱量
誰需要 : 敗血症、燒燙傷病人 ⮕他們處於高代謝狀態(蛋白質分解加劇)

(C)
A 24-h urine collection was conducted in all patients according to the nutritional support service protocol. Urine
collection was generally performed within 24 h of initiation of specialized nutritional support and approximately weekly thereafter while the patient resided in the trauma intensive care unit.

所以是需要計算的
(D)
Nitrogen balance (g ⁄ d) = nitrogen intake (g ⁄ d) -TUN (g ⁄ d) -2 (g ⁄ d)
The constant of 2 g of nitrogen in the nitrogen balance computation was an assumption of stool, integumentary,
and other insensible nitrogen losses.

註：可以用UUN(urinary urea nitrogen)來初步評估TUN(total urinary nitrogen)
