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.)
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.
