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.
