A nurse is preparing to administer haloperidol lactate 12 mg PO for a client who has schizophrenia and who cannot swallow tablets.

Available is haloperidol 2 mg/mL oral solution.

How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies.)

Answer and Explanation

The Correct Answer is ["6"]

Step 1 is to determine the amount of haloperidol lactate that needs to be administered, which is 12 mg.

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

Dose (mg) ÷ Concentration (mg/mL)

Given that the available concentration is 2 mg/mL, we calculate:

12 mg ÷ 2 mg/mL = 6 mL

Therefore, the nurse should administer 6 mL of the haloperidol oral solution.

So, the correct answer is 6 mL.

A. "Plan to relax in a hot tub spa each day.”. B. "Implement a schedule to include periods of rest.”. C. "Wait to perform difficult tasks until later in the day.”. D. "Limit your intake of dairy products.”.

Correct Answer is B

Explanation

Choice A rationale:

Relaxing in a hot tub spa each day is not recommended for MS patients as heat can exacerbate symptoms.

Choice B rationale:

Implementing a schedule to include periods of rest is beneficial as fatigue is a common symptom of MS12.

Choice C rationale:

Waiting to perform difficult tasks until later in the day is not necessarily beneficial as fatigue can occur at any time.

Choice D rationale:

Limiting intake of dairy products is not specifically related to managing MS12.

So, the correct answer is B.
