A nurse is reviewing a prescription for ibuprofen 150 mg PO with the parent of a child. Available is ibuprofen suspension 100 mg/5 mL. How many tsp should the nurse advise the parent to administer to the child? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
Step-by-step calculation:
The desired dose of ibuprofen is 150 mg.
The available medication concentration is 100 mg/5 mL.
We need to convert mL to tsp.
Calculating the volume to administer in mL:
Use the concentration of the medication: 150 mg ÷ (100 mg/5 mL) = 150 mg ÷ 20 mg/mL = 7.5 mL
Converting mL to tsp:
1 tsp = 5 mL
7.5 mL ÷ 5 mL/tsp = 1.5 tsp

Correct Answer is ["15"]
Explanation
Step-by-step calculation:
The child's weight is 55 lb.
The medication dosage is 15 mg/kg.
The available medication concentration is 125 mg/5 mL.
Calculating the total dose in mg:
Convert the child's weight to kg: 55 lb ÷ 2.2 lb/kg = 25 kg
Calculate the total dose: 25 kg × 15 mg/kg = 375 mg
Calculating the volume to administer:
Use the concentration of the medication: 375 mg ÷ (125 mg/5 mL) = 375 mg ÷ 25 mg/mL = 15 mL
Correct Answer is ["3.5"]
Explanation
Convert the child’s weight from pounds to kilograms:
52 lb÷2.2=23.6 kg.
Calculate the total daily dose in micrograms (mcg):
7.5 mcg/kg/day×23.6 kg=177 mcg/day.
Determine the volume in mL to administer:
The elixir concentration is 50 mcg/mL
177 mcg÷50 mcg/mL=3.54 mL.
Round to the nearest tenth:
3.54 rounds to 3.5 mL.
