Question 1 of 5

The healthcare provider prescribes lamivudine oral solution 150 mg twice daily for a client who is HIV positive. The available bottle contains 240 mL of lamivudine labeled, '10 mg/mL.' How many mL should the nurse administer in a 24 hour period?(Enter numeric value only.)

Correct Answer: 30

Rationale: The correct answer is 30 mL.
To find the answer, we can use the following steps: Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations. Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (total daily dose in mg) = (150) x (2) = 300 mg. (volume to be administered in mL) = (300) / (10) = 30 mL. (rounded volume to be administered in mL) = 30 mL.
Therefore, the nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.
