A 34-year-old woman residing in a long-term care facility has a seizure disorder and recently began using a walker after a fall-related hip fracture. She has a documented sulfa allergy that caused hives and facial swelling. The prescriber's order reads: "Phenytoin extended-release 300 mg PO once daily at bedtime for seizure prophylaxis, Dr. Alvarez, today 2000." The medication administration record confirms this order, and the client's morning phenytoin level was therapeutic. The LPN/VN prepares the 2000 dose from the medication cart, which contains 100 mg extended-release capsules. Two client identifiers are verified against the MAR. What should the LPN/VN do next?
- Open the capsules and mix the contents with applesauce before giving the dose.
- Administer 30 mg of phenytoin, calculating the dose as 300 mcg converted to mg.
- Give sulfamethoxazole-trimethoprim instead, since it is also stocked for prophylaxis.
- Administer three 100 mg extended-release capsules whole with water as ordered.
