A primary care provider prescribes amoxicillin 500 mg500\text{ mg} orally for a client. The pharmacy dispenses an oral suspension with a concentration of 250 mg250\text{ mg} per 5 mL5\text{ mL}. How many milliliters (mL\text{mL}) should the practical nurse administer per dose?

  2. B
    5 mL5\text{ mL}
  3. 10 mL10\text{ mL}Cevap
  4. D

Cevap

The nurse should administer 10 mL10\text{ mL} of the oral suspension per dose.
To find the correct volume, the prescribed dose (500 mg500\text{ mg}) must be divided by the available dose (250 mg250\text{ mg}), and then multiplied by the available volume (5 mL5\text{ mL}). The calculation is (500/250)×5=2×5=10 mL(500 / 250) \times 5 = 2 \times 5 = 10\text{ mL}.

Adım Adım Çözüm

1
Identify the desired dose prescribed by the provider.
The desired dose is 500 mg500\text{ mg}.
This is the target amount of medication the client needs to receive.
2
Identify the available concentration dispensed by the pharmacy.
The available dose is 250 mg250\text{ mg} in a volume quantity of 5 mL5\text{ mL}.
This determines the ratio of medication to liquid.
3
Calculate the volume to administer using the formula: (DesiredHave)×Quantity(\frac{\text{Desired}}{\text{Have}}) \times \text{Quantity}.
(500 mg250 mg)×5 mL=2×5 mL=10 mL(\frac{500\text{ mg}}{250\text{ mg}}) \times 5\text{ mL} = 2 \times 5\text{ mL} = 10\text{ mL}.
This provides the precise liquid volume needed to deliver the prescribed milligram dose.

This calculation can also be solved using ratio and proportion: 250 mg5 mL=500 mgX mL\frac{250\text{ mg}}{5\text{ mL}} = \frac{500\text{ mg}}{X\text{ mL}}. Cross-multiplying yields 250X=2500250X = 2500, resulting in X=10 mLX = 10\text{ mL}.
