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?.
Explanation & Rationale
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.
