Answer to Question 1

2

Rationale 1: Because the frequency of the medication has changed begin by determined the total daily dosage of the medication. When the client was receiving 75 mg of the medication every 8 hours the client received 25 x 3 or 75 mg of the medication. When the order changed, the client is receiving 15 mg x 2 or 30 mg of the medication. Now using the equation Fraction of Change = Change/Original, the equation will be Fraction of Change = 30/75 or 6/15. Convert this fraction into a decimal number by dividing 6 by 15 or 0.4 which is 40. The medication dosage was decreased by 40.

Answer to Question 2

3

Rationale 1: Using the equation Fraction of Change = Change/Original, calculate the equation Fraction of Change = 75/125 or 3/5. Change the fraction to a decimal by dividing 3 by 5 or 0.6 or 60. The dosage was changed by 60.
