这些不是英语缩写，而是拉丁语缩写 花了很长时间。让我们加一些点 呵呵呵呵 Definition of q.d. (on prescription) q.d. (on prescription): Seen on a prescription, q.d. (or qd) means one a day (from the Latin quaque die). The abbreviation is sometimes written without a period in capital letters as 'QD'. However it is written, it is one of a number of hallowed abbreviations of Latin terms that have been traditionally used in prescriptions to specify the frequency with which medicines should be taken. Other examples include: b.i.d. (bid or BID) is twice a day; b.i.d. stands for 'bis in die' (which means, in Latin, twice a day). t.i.d. (or tid or TID) is three times a day ; t.i.d. stands for 'ter in die' (in Latin, 3 times a day). q.i.d. (or qid or QID) is four times a day; q.i.d. stands for 'quater in die' (in Latin, 4 times a day). q_h: If a medicine is to be taken every so-many hours, it is written 'q_h'; the 'q' standing for 'quaque' and the 'h' indicating the number of hours. So, for example, '2 caps q4h' means 'Take 2 capsules every 4 hours.' 饭前接通每台交流电 点。A.s.t !皮肤试验 aq.dest。蒸馏水，2h。每2小时一次 每日两次。 急速地!很快! d。s。做标记 g 当h.s.睡着的时候 皮内注射，皮下注射 肌肉注射静脉注射 静脉滴注 静脉滴注 借!慢慢的! 指示：根据医生的指示指示md的用法 M.f.pl的混合物。是制成粉末的吗 毫克。毫克。毫升 这是医生的医嘱 paaa用于受灾地区 P单位p.c饭后 pg.
