Question

- The healthcare provider prescribes Amoxicillin 500 mg PO every 8 hours for a child who weighs 77 lbs. The available suspension is labeled, amoxicillin suspension 250 mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child’s weight?

Answer #1

Ordered dose= 500mg/8hr

Available dose = 250mg/5ml

Weight of child = 77 lbs **( 1 lbs = 0.454 kg
) **

Weight of child in kg = 35 kg ( 0.454 kg × 77lbs = 34.9kg )

Maximum dose in 24 hrs = 50mg/kg/24hr

Dose according to the age = **50mg × 35kg = 1750
mg**

Single dose in mg =**=
583.3mg**

**SINGLE DOSE
BASED ON CHILD WEIGHT**

*=***= 11.66 ml**

So the nurse must administer approximately
* 12ml* (of suspension ) single dose based
on the childs weight.
