A healthcare provider prescribes amoxicillin oral suspension for a toddler weighing $14\text{ kg}$ to treat acute otitis media. The prescription is for $30\text{ mg/kg/day}$ divided into two equal doses administered every 12 hours. The medication label indicates a concentration of $250\text{ mg}/5\text{ mL}$ . How many mL will the practical nurse administer for one dose? Record your answer to the nearest tenth. Do not include units in your answer.

Cevap: 4.2 mL

Cevap

4.2

To find the correct volume for one dose, first calculate the total daily requirement:

14\text{ kg} \times 30\text{ mg/kg/day} = 420\text{ mg/day}

. Next, divide this by

2

for the every-12-hour dosing schedule:

420\text{ mg/day} \div 2 = 210\text{ mg/dose}

. Finally, determine the liquid volume using the supplied concentration:

\frac{210\text{ mg}}{250\text{ mg}} \times 5\text{ mL} = 4.2\text{ mL}

Adım Adım Çözüm

Determine the total daily dose of the medication.

420\text{ mg/day}

The prescription is weight-based at

30\text{ mg/kg/day}

. Multiplying the weight (

14\text{ kg}

) by the dose per kg (

30\text{ mg}

) gives the total daily requirement.

Calculate the amount of medication needed for a single dose.

210\text{ mg/dose}

The daily dose is divided into two equal doses administered every 12 hours. Dividing the daily total (

420\text{ mg}

) by

2

gives the single dose amount.

Calculate the volume of liquid required for the single dose.

4.2\text{ mL}

Using the dosage formula

\frac{\text{Desired Dose}}{\text{Available Dose}} \times \text{Volume} = \frac{210\text{ mg}}{250\text{ mg}} \times 5\text{ mL} = 4.2\text{ mL}
