A nurse is preparing to administer lamivudine 150 mg PO BID. Available is lamivudine 100 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
1.5 tablets
Rationale
The correct answer is 1.5 tablets. To calculate this, we first need to determine the total dosage required per dose, which is 150 mg. Since each tablet is 100 mg, we divide 150 mg by 100 mg to find out how many tablets are needed. 150 mg ├À 100 mg = 1.5 tablets. Therefore, the nurse should administer 1.5 tablets per dose.
Choice A (1 tablet) is incorrect because it does not provide the full dosage of 150 mg per dose. Choice B (2 tablets) is incorrect because it would exceed the required dosage. Choices C-G are also incorrect for the same reason. The correct answer of 1.5 tablets balances the need for the full dosage while avoiding overdosing.
