Question 1

A pediatric client weighing 77 lbs.is prescribed fluid maintenance.How many mL per hour will the nurse set the infusion pump?
1)75 mL

Answer 1

1
Explanation: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.

Question 2

Answer 2

4.4 mL/dose
Explanation:mL/dose = 5 mL/105 mg x 27 mg/1 kg x 1 kg/2.2 lbs x 45 lbs/1 day x 1 day/6 doses.Multiply the numerators and then divide by the denominators.The nurse will administer 4.38 or 4.4 mL per dose.

Answer 3

3
Explanation: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.
