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 A
Explanation
Choice A rationale:
Dantrolene is a muscle relaxant used for relief of cramping, spasms, and tightness of muscles caused by multiple sclerosis. So, it should be taken regularly, not just when spasms are bad.
Choice B rationale:
While it’s important to communicate with the healthcare provider about the effectiveness of the medication, three months is a long time to wait without relief. The timeline should be discussed with the healthcare provider.
Choice C rationale:
The safety of dantrolene during pregnancy is not explicitly stated in the sources. It’s crucial to consult with a healthcare provider about this.
Choice D rationale:
There’s no specific mention of needing to check calcium levels while on dantrolene. Regular follow-ups for overall health monitoring are necessary, but this statement is not directly related to dantrolene use.
So, the correct answer is A.
Correct Answer is C
Explanation
Choice A rationale:
The client should maintain a normal fluid intake while taking lithium, not limit it to 800 ounces per day.
Choice B rationale:
Lithium can be taken with or without food. This instruction is not necessary.
Choice C rationale:
It can indeed take up to 3 weeks to see the full effects of lithium. This is a correct instruction.
Choice D rationale:
The client should maintain a normal sodium diet while taking lithium, not a low-sodium diet.
So, the correct answer is C, after analyzing all choices.
