Question

Order: tylonel elixir 10mg / kg every 4 hours prn for fever. supply: tylonel elixir 160 mg/ 5 ml. patient's weight: 17.6 lbs.

How many mL will you give? __________

Answer 1

To calculate the Tylenol elixir dosage, convert the patient's weight to kilograms, calculate the dose in mg, and convert that to mL using the medication's concentration. The result is to give 2.495 mL of Tylenol elixir.

Step-by-step explanation:

The student's question involves calculating the dosage of Tylenol elixir based on the patient's weight and the concentration of the medication. To find the correct dose in mL, we need to convert the patient's weight from pounds to kilograms, calculate the dose in mg, and then use the elixir concentration to convert the dose from mg to mL.

Step-by-step Calculation:

1. Convert weight from pounds to kilograms: 17.6 lbs × 0.453592 = 7.983 kilograms.
2. Calculate the dose in mg: 7.983 kg × 10 mg/kg = 79.83 mg.
3. Convert the dose to mL using the supply concentration: (79.83 mg × 5 mL) / 160 mg = 2.495 mL.

Therefore, you would give 2.495 mL of Tylenol elixir to the patient.
