Answer to Question 1

3

Rationale 1: mL/dose = 10 mL/500 mg x 150 mg/dose. Multiply the numerators and then divide by the denominators. The client will receive 3 mL/dose. This dose must be diluted in 100 mL of NS; therefore, the nurse will infuse 103 mL/dose.

Answer to Question 2

2

Rationale 1: The child's weight in kg = 33 lbs./2.2 = 15 kg. For the first 10 kg, multiply 10 100 mL/kg x 10 kg = 1000 mL. For the remaining 5 kg, multiply 50 mL/kg x 5 kg = 250 mL. The total fluid intake should be 1250 mL. Then, divide this amount by 24 or 1250/24 hr = 52.08 or 52 mL/hr.
