A nurse is preparing to administer lorazepam 1 mg PO at bedtime. The amount available is lorazepam 2 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.)

Answer and Explanation

The Correct Answer is ["0.5"]

To administer the correct dose of lorazepam, which is 1 mg, when only 2 mg tablets are available, the nurse should administer half a tablet. This is because each tablet contains 2 mg of lorazepam, and the prescribed dose is 1 mg. Therefore, dividing the tablet into two equal parts will provide the necessary 1 mg dose. The answer, rounded to the nearest tenth as per the instruction, is 0.5.
