A nurse is preparing to administer lorazepam 2 mg PO. Available is lorazepam 1 mg tablets.
How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
Step 1 is to determine the amount of lorazepam needed, which is 2 mg as prescribed.
Step 2 is to calculate the number of tablets required. Since each tablet contains 1 mg, we divide the prescribed dose by the strength per tablet:
2 mg ÷ 1 mg per tablet = 2 tablets
Therefore, the correct answer is 2 tablets.

Correct Answer is C
Explanation
Choice A rationale:
The client should maintain a normal fluid intake while taking lithium, not limit it to 800 ounces per day.

Lithium can be taken with or without food. This instruction is not necessary.
Choice C rationale:
It can indeed take up to 3 weeks to see the full effects of lithium. This is a correct instruction.

The client should maintain a normal sodium diet while taking lithium, not a low-sodium diet.
So, the correct answer is C, after analyzing all choices.
