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
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.
