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 ["6"]
Explanation
Step 1 is to calculate the volume of medication to administer. The formula is desired dose ÷ available dose × available volume. So, (300 mg ÷ 250 mg) × 5 mL = 6 mL.
So, the correct answer is 6 mL.
Correct Answer is D
Explanation
Choice A rationale:
Treating nasal rhinitis with an over-the-counter antihistamine is not directly related to neostigmine use or myasthenia gravis.
Choice B rationale:
If a medication dose is missed, wait until the next scheduled dose to take the medication is not the best advice. Neostigmine should be taken at regular intervals for maximum effectiveness.
Choice C rationale:
Expecting diaphoresis as a side effect of the neostigmine is not accurate. Diaphoresis is not a common side effect of neostigmine.
Choice D rationale:
Taking the medication 45 minutes before eating is correct. This timing helps maximize the medication’s effectiveness during meals, when muscle strength for swallowing is crucial.
So, the correct answer is,
D.
