Question

A dose of 156 mg of acetaminophen is prescribed for a 13−kg child. If one teaspoon contains 5.0 mL, how many teaspoons of Children’s Tylenol (80. mg of acetaminophen per 2.5 mL) must be administered?

Answer 1

Just under 1 tsp

Step-by-step explanation:

This is a situation where dimensional analysis is helpful....

156 mg / (80 mg / 2.5 ml * 5 ml / tsp ) =

156 mg / ( 160 mg/tsp) = .975 tsp ~~~ 1 tsp
