Answer 1

Given as weight of patient = 53 lbs. - = 24.0404 (As 1 lbs = 0.453 kg) Sate range of drug : 1-2 mcg/kg. i safe dose = ? Dose = Weight & available dose = 24.09X 1 OR 24.04 x 2 = 24.04 mcg OR 48.08 mcg Sake dose = 24.04 - 48.08 mcg Ans. - range lly ordered dose = 42 mcg Yes this is within sate range. y Available dose in = 50 mcg/ml ampule Ordered dose - 42 mcg It 50 mcg in 1 ml Then 42 mcg in xml 1 x x 50 = 1x42 - 2 = 42 ÷ 50 = 0.84 ml 1 ml - x = 0.01 m Ans (Round in 100thplace) -0.01ml would be administered

iry ordered dose = 0.68 mg Available dose = 5 mg 15 ml Given dose in ml = ? - If 5mg contains 5 ml Then 0.68 mg in xml . xx5 = 58 0.68 i x = 580.68 x= 0.68 ml Ž 1 ml x=0.01 mi (round to 100th place) Available. Lasix dose - lomg/ml prescribed dose - 25 mg weight of patient = 9.5 kg. Safe Range of drug = 1-6 mg/kgl day. If 10mg in 1 m) Then 25 mg in xml 10xx 0 = 25% I : x=25 + 10 = 2.5ml Dose = weight x ordened range of drug. = 9.5x2.5 = 23.75 mg day (calculated as taking i ng 1kg Iday)
