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.
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 ["10"]
Explanation
Step 1 is to calculate the number of tablets needed to administer 225 mg of desipramine. This is done by dividing the prescribed dose (225 mg) by the strength of each tablet (75 mg). So, 225 mg ÷ 75 mg/tablet = 3 tablets.
So, the correct answer is 3 tablets.
Correct Answer is C
Explanation
Choice A rationale:
The client should indeed notify their provider before taking any other medications, as phenytoin can interact with many other drugs. This statement does not indicate a need for further teaching.
Choice B rationale:
Regular dental appointments are important as phenytoin can cause gum hyperplasia. This statement does not indicate a need for further teaching.
Choice C rationale:
This statement indicates a misunderstanding. Phenytoin is used to control seizures, not cure them. The client should not stop taking the medication when their seizures stop.
Choice D rationale:
Phenytoin can be taken with or without food, but it should be taken consistently in the same manner. This statement does not indicate a need for further teaching.
So, the correct answer is C, after analyzing all choices.
