If a seizure persists for more than 5 minutes, what medication can be administered?

• A. Oral phenobarbital
• B. IV lorazepam or diazepam
• C. IM epinephrine
• D. Intranasal fentanyl

Answer: (B)

In the context of managing prolonged seizures, particularly status epilepticus, administering intravenous (IV) lorazepam or diazepam is the standard approach when a seizure lasts longer than 5 minutes. These medications are both benzodiazepines, which work quickly to enhance the inhibitory effects of gamma-aminobutyric acid (GABA) in the central nervous system, leading to rapid seizure cessation. Lorazepam is often preferred because it has a longer duration of action and a greater efficacy in stopping seizures compared to other options. Diazepam, while effective, has a shorter half-life and might require more frequent dosing. Administering these medications intravenously facilitates faster absorption and onset of action, critical in emergency scenarios to prevent potential complications from prolonged seizures, such as neuronal injury or increased morbidity. Other options provided do not serve as first-line treatments for this scenario. Oral phenobarbital is an anticonvulsant but is typically not used in acute settings due to its slower onset. Intramuscular (IM) epinephrine is not used for seizures and is more relevant in the context of anaphylactic reactions. Intranasal fentanyl is an opioid and is not indicated for seizure management; it primarily addresses severe pain. Therefore,
