A client is prescribed ibuprofen $400\text{ mg}$ orally every $6$ hours for musculoskeletal pain. The available medication is an oral suspension labeled $100\text{ mg}/5\text{ mL}$ . How many milliliters ( $\text{mL}$ ) should the practical nurse administer per dose? Record your answer as a whole number. Do not include units in your answer.

Cevap: 20 mL

Cevap

To calculate the correct volume to administer, use the standard formula:

(\frac{\text{Desired dose}}{\text{Dose on hand}}) \times \text{Volume}

. The desired dose is

400\text{ mg}

and the dose on hand is

100\text{ mg}

per

5\text{ mL}

. Substituting these values into the formula gives

(\frac{400\text{ mg}}{100\text{ mg}}) \times 5\text{ mL}

. Dividing

400

100

equals

4

. Multiplying

4

5\text{ mL}

yields the correct administration volume of

20\text{ mL}

Adım Adım Çözüm

Identify the desired dose prescribed by the provider.

Desired dose =

400\text{ mg}

This is the target amount of medication the client needs to receive.

Identify the dose on hand (concentration) and its corresponding volume.

Have =

100\text{ mg}

, Quantity =

5\text{ mL}

This establishes the ratio of medication weight to liquid volume available from the pharmacy.

Apply the dosage calculation formula.

Formula:

(\frac{\text{Desired}}{\text{Have}}) \times \text{Quantity}

This formula converts the prescribed milligrams into the administrable milliliters.

Substitute the values into the formula and perform the calculation.

(\frac{400}{100}) \times 5 = 4 \times 5 = 20\text{ mL}

Completing the math yields the exact volume to administer per dose.
