A nurse is preparing to administer lorazepam 1 mg PO to an older adult client who has insomnia and who cannot swallow oral tablets.

Available is lorazepam oral solution 2 mg/mL. How many mL should the nurse plan to administer?
(Round to the nearest tenth. Use a leading zero if it applies.)

Answer and Explanation

The Correct Answer is ["0.5"]

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.

Correct Answer is A

Explanation

Choice A rationale:

Risperidone can indeed increase triglyceride levels. The nurse should monitor this.

Choice B rationale:

Risperidone is more likely to cause weight gain, not weight loss. This is not a common adverse effect.

Choice C rationale:

Risperidone does not typically elevate blood pressure. This is not a common adverse effect.

Choice D rationale:

Risperidone does not typically decrease blood glucose levels. This is not a common adverse effect.

So, the correct answer is A, after analyzing all choices.

Correct Answer is ["3"]

Explanation

Step 1 is to determine the total amount of medication needed, which is 750 mg. Step 2 is to convert the medication needed into mL using the medication’s concentration. So, 750 mg ÷ (250 mg/5 mL) = 15 mL.

So, the correct answer is 15 mL.
