Answer to Question 1

2

Rationale 1: mg/dose = 0.6 mg/1 kg x 1 kg/2.2 lbs x 55 lbs/8 hours x 4 hrs/dose. Multiply the numerators and then divide by the denominators. The client can receive 15 mg/8 hours. The client will receive 7.5 mg/dose.

Answer to Question 2

3

Rationale 1: First, determine the safe dose range for this medication. Mg/day = 25 mg/1 kg x 1 kg/2.2 lbs x 44 lbs = 500 mg/day; mg = 50 mg/1 kg x 1 kg/2.2 lbs x 44 lbs = 1000 mg. The one dose that is within the parameters is 400 mg PO q 12 hours.
