Answer 1

. Available dose = 20 mg/ml oodered dose = 30 mg solution If 20 mg in 1 ml Then x mg in 12 ml 12 x 20 XX1 i X = 240 mg 2 If 20mg in 1 ml Then 30mg in xml . XX 20 = 30x1 ai x = 30 = 1.5 - 20 15 ml will be administered IV rate = volume in mi Time in min = 1,5 -0.5 3 IV Flow rate = 0.5 ml / min

4 IV factor. rate = volume x Drop - Time 0.5 = 01.5 xx - = x 3X0.5 15 x = 1 drop/ min 20 mg in 1 ml x mg in 0. 5ml 20x0.5 = xxl 10mg = x . 10 mg/min will be administered . © Ordered dose = 30 mg BD (twice a day) Dose = 30x 2 required = 60 mg/day
