Answer to Question 1

3

Rationale 1: mL/dose = 5 mL/120 mg x 10 mg/1 kg x 1 kg/2.2 lbs x 44 lbs/1 dose. Multiply the numerators and then divide by the denominators. The child receives 8.3 mL of medication per dose.

Answer to Question 2

3

Rationale 1: First, convert the client's weight in lbs to kg. kg = 1 kg/2.2 lbs x 99 lbs. Multiply the numerators and then divide by the denominators. The client weight is 45 kg. To determine the client's fluid needs:
mL = 100 mL/1 kg x 10 kg. Multiply the numerators and then divide by the denominators. For the first 10 kg of weight, this child requires 1000 mL of fluid.
mL = 50 mL/1 kg x 10 kg. Multiply the numerators and then divide by the denominators. For the second 10 kg of weight, this child requires 500 mL.
mL = 20 mL/1 kg x 25 kg. Multiply the numerators and then divide by the denominators. For the second 10 kg of weight, this child requires 500 mL.
The client requires a total of 2000 mL/24 hrs, or 83 mL/hr. To determine gtts/min = 15 gtts/1 mL x 83 mL/1 hr x 1 hr/60 min. The nurse sets the infusion at 21 gtts/min.
