At 1200, the practical nurse (PN) learns that a client's 0900 dose of an anticonvulsant was not given. The next scheduled dose is at 2100. Which action should the PN take?

A. Administering half of the missed dose is not generally recommended because it could lead to inconsistent drug levels and potential for breakthrough seizures. The standard practice is to follow the dosing schedule unless otherwise instructed by the healthcare provider. B. Giving the missed dose with the next scheduled dose may lead to double dosing and could increase the risk of side effects or toxicity. The missed dose should be addressed as soon as possible but not in combination with the next dose. C. Withholding the missed dose unless seizure activity occurs could put the client at risk for seizures. Anticonvulsants should be administered as per the prescribed schedule to maintain therapeutic drug levels and prevent seizures. D. Administering the missed dose as soon as possible is the correct approach, following standard guidelines for missed medications. The missed dose should be given promptly unless it is close to the time of the next dose, in which case the next dose should be given as scheduled.
