Question: A certain medication is given according to body weight. Dosage is 1/2 tsp for every 15 pounds of body weight. Set up and solve a proportion to determine the number of teaspoons to administer a patient weighing 120 pounds.

Answer: Method I

1/2 teaspoon for every 15 pounds of body weight.

Patient body weight = 120pounds

Dosage = 120pounds / 15pounds 1/2 teaspoon

= 8 times 1/2 teaspoon(8 1/2)

= 4 teaspoons

Method II

1teaspoon = 5ml

  1/2 teaspoon = 2.5ml

2.5ml for every 15 pounds of body weight.   

Patient body weight = 120pounds

Dosage = 120pounds / 15pounds 2.5ml

= 8 2.5ml

= 20ml

Number of teaspoons = total / 1teaspoon

= 20ml / 5ml

= 4 teaspoon
