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?.

A.

Switch phenytoin brands with each refill.

B.

Alter the phenytoin administration regimen each week.

C.

Phenytoin turns urine blue.

D.

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.

Explanation

Choice A rationale:

Slow pulse is not a common side effect of benztropine.

Choice B rationale:

Difficulty voiding is a known side effect of benztropine due to its anticholinergic effects.

Choice C rationale:

Excessive salivation is not a common side effect of benztropine, dry mouth is more common.

Choice D rationale:

So, the correct answer is B.

Correct Answer is A

Explanation

Choice A rationale:

Withholding the dose if having a fine hand tremor is not recommended. Hand tremors are a common side effect of lithium, but they can be managed by adjusting the dose.

Choice B rationale:

Avoiding foods with a high tyramine content is not necessary for lithium users. This dietary restriction is typically associated with certain antidepressants, not lithium.

Choice C rationale:

Limiting daily fluid intake is incorrect. Lithium can cause increased thirst and urination, so it’s important to maintain adequate hydration.

Choice D rationale:

Following a low-sodium diet is not advised. Both salt and fluid can affect the levels of lithium in your blood, so it’s important to consume a steady amount every day.

So, the correct answer is, none of the above.
