Correct Answer is B

Explanation

Choice A rationale:

Acamprosate is used to help manage alcohol dependence, but it’s not typically used for acute withdrawal symptoms.

Choice B rationale:

Lorazepam is a benzodiazepine, which is the first-line treatment for alcohol withdrawal delirium due to its efficacy in reducing withdrawal symptoms and preventing complications.

Choice C rationale:

Disulfiram is used as a deterrent for alcohol consumption, not for managing withdrawal symptoms.

Choice D rationale:

Methadone is used for opioid dependence, not alcohol withdrawal.

So, the correct answer is B. Lorazepam.

Correct Answer is ["0.5"]

Explanation

Step 1 is to determine the amount of lorazepam that needs to be administered, which is 1 mg.

Step 2 is to calculate the volume of lorazepam oral solution needed to deliver this dose. This is done using the formula:

Dose (mg) ÷ Concentration (mg/mL)

Given that the solution has a concentration of 2 mg/mL, we calculate:

1 mg ÷ 2 mg/mL = 0.5 mL

Therefore, the nurse should administer 0.5 mL of lorazepam oral solution.
