Ati dosage calculation lpn paediatrics nursing proctored assessment 3.2 ( 35 Questions)
A nurse is preparing to administer prednisolone 2 mg/kg/day PO divided in equal doses every 12 hr to a toddler who has acute asthma and weighs 26lb. Available is prednisolone syrup 15 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 3.9
Step-by-Step Solution:
Convert the toddler's weight from pounds to kilograms.
1 pound= 0.453592 kilograms.
26 pounds = 26 x 0.453592 = 11.793592 kilograms.
Calculate the total daily dose of prednisolone.
The prescribed dose is 2 mg/kg/day.
The toddler weighs 11.793592 kg.
Total daily dose = 2 mg/kg/day x 11.793592 kg = 23.587184 mg/day.
Determine the dose per administration.
Total daily dose is divided into two equal doses (every 12 hours).
The dose per administration = 23.587184 mg/day / 2 = 11.793592 mg per dose.
Calculate the volume of prednisolone syrup to administer.
The available prednisolone syrup is 15 mg/5 ml.
To find the volume, we can set up a proportion:
15 mg / 5 ml = 11.793592 mg / x ml
Cross-multiplying:
15x = 5 x 11.793592
Solving for x:
x = (5 x 11.793592) / 15 = 3.931197 ml
Round the answer to the nearest tenth.
3.9 mL
