下面小编为大家准备了 研究生入学 的相关考题,供大家学习参考。

患者胁肋刺痛,痛有定处,痛处拒按,入夜痛甚,胁肋下或见有癜块,舌质紫暗,脉象沉涩。治宜选用

A.膈下逐瘀汤
B.鳖甲煎丸
C.桃核承气汤
D.血府逐瘀汤
答案:D
解析:
上述症状属于胁痛之瘀血阻络证。其病机为瘀血停滞,肝络痹阻。治宜祛瘀通络。代表方为血府逐瘀汤或复元活血汤。

该患者不,出现的心音变化是
A.心尖?部一心音增强 B.心尖部第一心音可呈拍击性
C.肺动脉瓣区第二心音增强 D.心尖部第二心音增强

答案:D
解析:
患者呼吸困难,双下肢水肿,肝瘀血,表明为右心衰竭。从76题给出的4个答案项 来看,最可能为二尖瓣狭窄,因此心尖部可听到舒张期杂音。若将答案选为D(主动脉瓣狭窄),则与题意 不符。二尖瓣狭窄由于左心房大,不会出现心尖搏动向左下移位及靴形心。二狭为梨形心。②二狭患者 由于舒张期左心室充盈不足,导致第一心音亢进。若瓣叶柔顺,活动度好,则心尖部第一心音可呈拍击 性。由于二狭患者常有肺动脉高压,因此肺动脉瓣区第二心音增强,不会出现心尖部第二心音增强。

CO2由血液进入肺泡属于
A.单纯扩散 B.易化扩散 C.原发性主动转运 D.继发性主动转运

答案:A
解析:
Na快速跨越质膜是经NaH通道的易化扩散。Na +-K+-ATP 酶将Na+移出胞外是经钠泵进行的原发性主动转运。Na +-Ca2+交换所需的能量并不直接来自ATP的分 解,而是利用细胞膜两侧Na'的浓度差将细胞内的Ca2+排出细胞,属于继发性主动转运。二氧化碳的跨 膜转运方式是单纯扩散。
