Question

A 22-pound child was admitted with acute bronchitis. Her medical orders include Garamycin 2.5 mg/kg q 8h. You receive Garamycin from the pharmacy in a vial labeled 10 mg/ml. Determine the number of milliliters required per dose.

Answer 1

Answer:

2.4948ml

Step-by-step explanation:

First, we change the child's weight into kilograms:

$22pounds=9.9790kgs$

From the info, the dose is recommended as 2.5mg/kg. Let x be the number of mg administered to the child:

$1kg=2.5mg\\9.9790kg=x\\\\x=2.5\times9.9790\\\\x=24.9475mg$

#The drug contains 10mg/ml . Let y be the dose size administered, equate and solve for y:

$10mg=1ml\\24.9475mg=y\\\\\thereforey= \frac{1ml\times24.9475mg}{10mg}\\\\y=2.4948$

Hence, the dose required is 2.4948ml
