Calculate the dosage in mL if the order is for 250 mg of medication that comes in a concentration of 100 mg/mL.

Calculate the dosage in mL if the order is for 250 mg of medication that comes in a concentration of 100 mg/mL.

• A. 2.5 mL
• B. 3.0 mL
• C. 2.0 mL
• D. 1.5 mL

Answer: (A)

To determine the correct dosage in mL for the medication, you can use the formula that relates dosage, concentration, and volume: \[ \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}} \] In this case, the desired dose is 250 mg, and the concentration of the medication is 100 mg/mL. Plugging in the values gives: \[ \text{Volume (mL)} = \frac{250 \text{ mg}}{100 \text{ mg/mL}} \] When you perform the division: \[ \text{Volume (mL)} = 2.5 \text{ mL} \] Thus, the correct dosage to administer is 2.5 mL. This aligns with the concentration provided, as for every 100 mg of medication, there is 1 mL of solution. Therefore, to achieve a total of 250 mg, you indeed need 2.5 mL of the solution.

To determine the correct dosage in mL for the medication, you can use the formula that relates dosage, concentration, and volume:

[ \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}} ]

In this case, the desired dose is 250 mg, and the concentration of the medication is 100 mg/mL.

Plugging in the values gives:

[ \text{Volume (mL)} = \frac{250 \text{ mg}}{100 \text{ mg/mL}} ]

When you perform the division:

[ \text{Volume (mL)} = 2.5 \text{ mL} ]

Thus, the correct dosage to administer is 2.5 mL. This aligns with the concentration provided, as for every 100 mg of medication, there is 1 mL of solution. Therefore, to achieve a total of 250 mg, you indeed need 2.5 mL of the solution.
