A nurse is reinforcing discharge teaching with a client who has a prescription for phenytoin.
Which of the following instructions should the nurse include in the teaching?.

Switch phenytoin brands with each refill.

Alter the phenytoin administration regimen each week.

Phenytoin turns urine blue.

Alcohol increases the chance of phenytoin toxicity.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is B

Explanation

Choice A rationale:

Fresh fish is not a food that needs to be eliminated from the diet of a client taking an MAOI like selegiline. It does not contain tyramine, which can cause a hypertensive crisis in clients taking MAOIs.

Choice B rationale:

Cheddar cheese is a food high in tyramine and should be eliminated from the diet of a client taking an MAOI. Consuming foods high in tyramine can lead to a hypertensive crisis in these clients.

Choice C rationale:

Cherries are not a food that needs to be eliminated from the diet of a client taking an MAOI. They do not contain tyramine.

Choice D rationale:

Chicken is not a food that needs to be eliminated from the diet of a client taking an MAOI. It does not contain tyramine.

So, the correct answer is B. Cheddar cheese.

Correct Answer is ["3.5"]

Explanation

Answer and explanation

Step 1 is to calculate the volume of haloperidol lactate oral solution that contains 7 mg of haloperidol lactate. This is done by dividing the prescribed dose (7 mg) by the concentration of the oral solution (2 mg/mL). So, 7 mg ÷ 2 mg/mL = 3.5 mL.

So, the correct answer is 3.5 mL.
