Answer to Question 1

2

Rationale 1: mL/dose = 20 mL/1 g x 1 g/1000 mg x 30 mg/1 kg x 1 kg/2.2 lb x 44 lb/day x 1 day/4 doses. Multiply the numerators and the divide by the denominators. The client will receive 3 mL of medication at each dose; therefore, the nurse will need to add 97 mL of fluid to the volume controlled chamber.

Answer to Question 2

1

Rationale 1: First determine the child's body surface area by using the equation, BSA = 96 lbs. x 50 in/3131 = 4800/3131 = 1.15330565 = 1.24 m2. mL/dose = 0.5 mL/100 mcg x 50 mcg/m2 x 1.24/1 dose. Multiply the numerators and then divide by the denominators. The client will receive 0.31 mL of medication.
