问题 单项选择题 B型题

诱发心绞痛的是()

A.碘化物

B.β受体拮抗剂

C.甲状腺激素

D.反射性I

E.硫脲类

答案

参考答案:C

解析:应用碘化物可在用药后立即或几小时后发生急性反应,主要表现为血管神经性水肿,上呼吸道水肿及严重喉头水肿;过量的甲状腺激素可引起甲状腺功能亢进的临床表现,在老人和心脏病患者中,可发生心绞痛和心肌梗死,可用β受体阻断药对抗,停用甲状腺激素;服用硫脲类常见的不良反应有瘙痒、药疹等过敏反应,严重不良反应有粒细胞缺乏症,一般发生在治疗后的2~3个月内,故应定期检查血象,若用药后出现咽痛或发热,立即停药则可恢复;I辐射只限与甲状腺内,易致甲状腺功能低下,故应严格掌握剂量和密切观察有无不良反应,一旦发生甲状腺功能低下可补充甲状腺激素对抗之;长期服用碘化物可诱发甲亢。
