A nurse is preparing to administer lorazepam 2 mg PO.
Available in lorazepam 1 mg tablets.
How many tablets should the nurse administer?
1.
2.
3.
4.
The Correct Answer is B
The nurse should administer 2 tablets of lorazepam 1 mg to give a total dose of 2 mg.
This is calculated by dividing the desired dose (2 mg) by the available dose (1 mg/tablet) to get the number of tablets needed: 2 mg / (1 mg/tablet) = 2 tablets.
Choice A, 1 tablet, is not the correct answer because it would only provide a total dose of 1 mg.
Choice C, 3 tablets, is not the correct answer because it would provide a total dose of 3 mg.
Choice D, 4 tablets, is not the correct answer because it would provide a total dose of 4 mg.
