Quizlet NCLEX PN 2023 - Nurselytic

Correct Answer: D

Rationale: Phenytoin is incompatible with dextrose solutions as they will precipitate when mixed together.
Therefore, it should not be piggybacked into the D10W solution or given through the same port. Instead, normal saline should be used to flush before and after administering phenytoin to prevent any interaction with the dextrose solution. Delaying the administration of an antiepileptic drug like phenytoin to maintain therapeutic blood levels is not recommended, so it should not be given after the D10W is finished or based on the medication port closest to the client.
Choice A is incorrect because administering phenytoin after the D10W is finished is not the correct approach due to the incompatibility with dextrose solutions.
Choice B is incorrect as the timing of phenytoin administration should not be based on the medication port closest to the client but on compatibility considerations.
Choice C is incorrect as piggybacking phenytoin into the D10W solution is not advisable due to the incompatibility issue.
