A nurse has to administer 17.1 mg of ondansetron to a client before chemotherapy. The 10 mL vial contains 3 mg/mL.
How much solution should the nurse withdraw from the vial?

1.71 mL

5.7 mL

10 mL

17.1 mL

Answer and Explanation

The Correct Answer is B

The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:

Amount of solution = Amount of medication needed / Concentration of medication in the solution.

In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:

Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL

Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.

It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.
