问题 健康足月男婴,6个月,体重8kg,采用人工喂养,该小儿每日除8%糖牛奶外,还需要喂水的量为
选项 A、660ml B、320ml C、780ml D、880ml E、1200ml
答案 B
解析 根据小儿每日所需能量为110kcal/kg·1克糖可产生4kcal热量,100ml牛奶可产生66kcal热量进行计算。该小儿每日需热量为110×8=880kcal,100ml8%糖牛奶可产生热量:66+100×8%×4-98kcal,可列方程100:98=X:880,得出该小儿每日需8%糖牛奶880ml。而小儿每日需水为150ml/kg,因此该小儿每日需水150×8=1200ml,除去牛奶,还需水1200-880=320ml。
