Answer to Question 1

4

Rationale 1: mL/dose = 1 mL/0.25 mg x 1 mg/1000 mcg x 25 mcg/1 kg x 1 kg/2.2 lbs x 33 lbs/d. The child will receive 1.5 mL of medication per dose.

Answer to Question 2

4

Rationale 1: mL/dose = 5 mL/250 mg x 7.5 mg/1 kg x 1 kg/2.2 lbs x 66 lbs/1 dose. Multiply the numerators and then divide by the denominators. The client will receive 4.5 mL/ dose.
