Answer 1

A nurse is preparing to administer amoxicillin 100 mg PO. Available is 210 mg/4mL. How many mL should the nurse administer?

answer:1.9ml

Solution with formula and calculation:

As the nurse is preparing to administer amoxicillin 100 mg PO,the desired dose is 100mg.

Desired dose D=100mg PO

Available is 210 mg/4mL

dose at hand H=210mg

volume at hand V= 4ml

Formula:

dose= (desired dose D / dose at hand H ) * Volume V

Calculation of the dose :

dose= (desired dose D / dose at hand H ) * Volume V

dose=[100mg/210mg] * 4ml

dose=400/210 ml

dose=1.90ml

answer: The nurse should administer 1.9ml of amoxicillin PO.
