Cevap

The nurse should administer

10

mL for a single dose.

Using the standard formula

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

, the calculation is

(\frac{250 \text{ mg}}{125 \text{ mg}}) \times 5 \text{ mL}

. This simplifies to

2 \times 5 \text{ mL}

, which equals exactly

10 \text{ mL}

Adım Adım Çözüm

Identify the desired dose ordered by the provider.

250

This establishes the target amount of medication the client must receive.

Identify the concentration of the medication on hand.

125

mg in every

5

This establishes the relationship between the drug weight and the liquid volume.

Set up the dosage calculation formula:

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

(\frac{250}{125}) \times 5

This standard formula converts the prescribed weight into the correct physical volume to administer.

Perform the mathematical operation to determine the final volume.

2 \times 5 = 10

This calculation ensures the client receives exactly the

250

mg ordered.
