If a patient needs 1050 mg of medication and the vial contains 350 mg in 5 mL, how many mL should be administered?

• A. 5 mL
• B. 10 mL
• C. 15 mL
• D. 20 mL

Answer: (C)

To determine how many mL should be administered to achieve a dosage of 1050 mg when the vial contains 350 mg in 5 mL, start by figuring out the concentration of the medication in the vial. The vial contains 350 mg in 5 mL. This can be expressed as: 350 mg / 5 mL = 70 mg/mL. Next, to find out how many mL are needed for the required 1050 mg, you can set up the following calculation: Desired dosage (1050 mg) divided by the concentration (70 mg/mL): 1050 mg / 70 mg/mL = 15 mL. This means that to administer a total of 1050 mg, you would need to provide 15 mL of the medication from the vial. Therefore, the correct answer is the amount calculated: 15 mL. This correctly reflects the dosage needed based on the concentration in the vial.

To determine how many mL should be administered to achieve a dosage of 1050 mg when the vial contains 350 mg in 5 mL, start by figuring out the concentration of the medication in the vial.

The vial contains 350 mg in 5 mL. This can be expressed as:

350 mg / 5 mL = 70 mg/mL.

Next, to find out how many mL are needed for the required 1050 mg, you can set up the following calculation:

Desired dosage (1050 mg) divided by the concentration (70 mg/mL):

1050 mg / 70 mg/mL = 15 mL.

This means that to administer a total of 1050 mg, you would need to provide 15 mL of the medication from the vial.

Therefore, the correct answer is the amount calculated: 15 mL. This correctly reflects the dosage needed based on the concentration in the vial.
