Question

a nurse is preparing to administer amoxicillin 250 mg po to a school-age child. the amount available is amoxicillin oral suspension 200 mg/5 ml. how many ml should the nurse administer per dose? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Identify the given parameters

The prescribed dose of amoxicillin is \(250\text{ mg}\). The available concentration of amoxicillin oral suspension is \(200\text{ mg}/5\text{ mL}\).

Calculate the volume to administer

Using the formula:

$$ \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Have (mg)}} \times \text{Quantity (mL)} $$

Substitute the given values:

$$ \text{Volume} = \frac{250\text{ mg}}{200\text{ mg}} \times 5\text{ mL} = 1.25 \times 5\text{ mL} = 6.25\text{ mL} $$

Round to the nearest tenth

Rounding \(6.25\text{ mL}\) to the nearest tenth yields \(6.3\text{ mL}\).
