“发汗多，若重发汗者，亡其阳”（《伤寒论》），其病机是

A.津亏气耗
B.津随气脱

解析：
气随液脱主要指由于津液大量丢失，气失其依附而随津液外泄，从而导致阳气爆脱亡失的病理状态。多由于大汗伤津，或严重吐泻，耗伤津液所致。《伤寒论·阳明病脉证并治》中说：“发汗多，若重发汗者，亡其阳”。
可出现黄腻苔的是

A.痰热内阻证
B.湿热内蕴证
C.痰饮化热证
D.食积化热证
答案：A,B,C,D
解析：
腻苔主痰浊、食积，多由湿浊内蕴，阳气被遏，湿浊痰饮停聚舌面所致。舌苔薄腻，多为食积，或脾虚湿困，阻滞气机；苔白腻而滑，为痰浊、寒湿内阻，阳气被遏。黄苔主热证、里证。故痰热、湿热、食积等邪内蕴化热可出现黄腻苔。
