Regarding the treatment of HHNC, which statement is correct?

In the context of treating Hyperglycemic Hyperosmolar Nonketotic Coma (HHNC), the statement regarding the effectiveness of phenytoin for seizures is correct. It is important to recognize that patients experiencing HHNC may often exhibit neurological complications, including seizures. Phenytoin is a commonly used antiepileptic medication that works by stabilizing neuronal membranes and preventing the propagation of abnormal electrical discharges in the brain, thus it can be effective for managing seizures in this patient population.

Patients with HHNC often have markedly elevated glucose levels and may present with altered mental status or seizures due to severe hyperosmolarity and dehydration. Managing these symptoms is crucial, and administering phenytoin can help control seizure activity while the underlying hyperglycemic state is addressed.

Addressing the other options, correcting fluid deficits appropriately is critical in the management of HHNC, and hence the statement regarding this correction only being half in the first hour might lead to inadequate rehydration. Monitoring glucose levels is essential even in non-acidotic patients, as fluctuations can still occur, reflecting ongoing metabolic disturbances. Additionally, hyperosmolarity requires careful correction; doing so too quickly can lead to complications such as cerebral edema. Thus, all these factors underline
