Answer to Question 1

1

Rationale 1: First, convert the client's weight in lbs to kg. kg= 1 kg/2.2 lbs x 77 lbs. Multiply the numerators and then divide by the denominators. The client weight is 35 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 15 kg. Multiply the numerators and then divide by the denominators. For the second 10 kg of weight, this child requires 300 mL.
The client requires a total of 1800 mL/24 hrs and will receive 75 mL/hr.

Answer to Question 2

Rationale 1: mL/dose = 5 mL/5 mg x 0.1 mg/1 kg x 1 kg/2.2 lbs x 110 lbs/dose. Multiply the numerators and then divide by the denominators. The client will receive 5 mL of medication per dose. In order for the nurse to have 50 mL in the chamber, 45 mL of fluid must be added.
