A practical nurse is preparing to administer a prescribed dose of oral amoxicillin suspension to a pediatric client who weighs $14 \text{ kg}$ . The provider's prescription states: amoxicillin $40 \text{ mg/kg/day}$ by mouth divided into two equal doses every $12$ hours. The pharmacy dispenses amoxicillin suspension at a concentration of $250 \text{ mg}/5 \text{ mL}$ . How many $\text{mL}$ should the nurse administer per dose? (Record your answer to the nearest tenth. Do not include units in your answer.)

Cevap: 5.6 mL

Cevap

The nurse should administer 5.6 mL per dose.

To ensure safe medication administration, the nurse must accurately convert the prescribed weight-based parameter into a measurable fluid volume. By calculating the total daily dose (

560 \text{ mg}

), dividing it into the specified two doses (

280 \text{ mg}

each), and applying the concentration formula (

\frac{\text{Desired}}{\text{Have}} \times \text{Volume}

), the correct verifiable dose is

5.6 \text{ mL}

Adım Adım Çözüm

Determine the total daily dose in milligrams based on the client's weight.

14 \text{ kg} \times 40 \text{ mg/kg} = 560 \text{ mg/day}

Weight-based prescriptions require calculating the total 24-hour medication allowance before determining individual dose amounts.

Determine the individual dose amount in milligrams.

560 \text{ mg} \div 2 = 280 \text{ mg/dose}

The prescription specifies that the total daily amount must be divided into two equal doses administered every 12 hours.

Calculate the liquid volume to administer per dose using the supplied concentration.

(\frac{280 \text{ mg}}{250 \text{ mg}}) \times 5 \text{ mL} = 5.6 \text{ mL}

This converts the required milligram dose into the measurable milliliter volume provided by the pharmacy.
