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.

Correct Answer is ["10"]

Explanation

Step 1 is to calculate the amount of hydroxyzine HCL in each mL of the oral suspension. This is done by dividing the total amount of hydroxyzine HCL (25 mg) by the total volume (5 mL), which gives us 5 mg/mL. Step 2 is to calculate the volume of oral suspension that contains 50 mg of hydroxyzine HCL. This is done by dividing the prescribed dose (50 mg) by the concentration of the oral suspension (5 mg/mL). So, 50 mg ÷ 5 mg/mL = 10 mL.

So, the correct answer is 10 mL.

Correct Answer is A

Explanation

Choice A rationale:

Developing a respiratory infection can indeed trigger a myasthenic crisis. Any form of stress on the body, including infections, can exacerbate symptoms.

Choice B rationale:

Taking too much prescribed medication is not typically a cause of myasthenic crisis. However, medication changes should always be managed carefully.

Choice Crationale:

Insufficient sleep can contribute to overall stress and fatigue, potentially exacerbating symptoms, but it is not a primary cause of myasthenic crisis.

Choice Drationale:

Insufficient exercise is not a known trigger for myasthenic crisis. While regular exercise can help manage symptoms, lack of exercise is not a direct cause.
