1.The label on a 30 mL aminophylline vial indicates a strength of 500 mg/20 mL. How many mL of aminophylline would contain 225 mg of the drug?

2.The order reads to give 0.375 grams of amoxycillin trihydrate every 8 hours. On hand you have 125 milligrams in 5 milliliters. How many milliliters will you administer?

Expert Solution

Question no 1

Let us consider the ordered dose as 225mg

Ordered dose(D) = 225 mg

Dose in hand ( H) = 500 mg

Quantity it is in ( Q) = 20 ml

Amount to be administered (A) = ?

A= D×Q/ H

A= 225×20/ 500= 9

So 9 ml is required

Question no 2

Ordered dose(D) = .375 grams , conversation to mg ,0.375 gram =375 milligrams( × 100)

Dose in hand ( H) = 125mg

Quantity it is in ( Q) = 5 ml

Amount to be administered (A) = ?

A= D×Q/ H

A=375× 5/ 125

= 15 ml
