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.)

Choice A rationale:

Switching brands of phenytoin can lead to variations in drug absorption and serum drug levels, potentially leading to a loss of seizure control or toxicity. Therefore, this is not a correct instruction.

Choice B rationale:

Altering the phenytoin administration regimen each week can lead to fluctuations in serum drug levels, potentially leading to a loss of seizure control or toxicity. Therefore, this is not a correct instruction.

Choice C rationale:

Phenytoin does not turn urine blue. This is a side effect associated with some other medications, but not phenytoin. Therefore, this is not a correct instruction.

Choice D rationale:

Alcohol can increase serum phenytoin levels, potentially leading to toxicity. Therefore, this is a correct instruction.

So, the correct answer is D. Alcohol increases the chance of phenytoin toxicity.

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.
