1. Order: amoxicillin (Amoxil) 60 mg po q8h Child: Weight 20 lb Supply: amoxicillin (Amoxil) 125 mg/5 mL Recommended dose: 20 to 40 mg/kg/day in divided doses q8h What is the maximum recommended dose for the child's weight? number) How much will you administer per dose? mg/dose (round to the whole ml.

Answer 1

Child weight = 20lb ( 1kg = 2.2 lb)

So child weight = 9.09 kg

Recommended dose = 20 to 40 mg/kg/day

Maximum recommended dose for the child = 40*9.09

= 363. 6mg/day

= 364 mg/day ( approximately )

q8h = 364/3

= 121.3mg/dose

= 121mg ( approximately )

= 121mg q8h is the maximum dose recommended for the child.

Available Amoxycilline = 125mg/5ml

Given order is 60mg q8h

1ml = 25 mg

1 ml * 2.4 = 25 mg* 2.4

2.4 ml = 60 mg

Therefore we have to administer 2.4ml per dose to deliver 60mg of Amoxycilline .
