If a patient has a hypoglycemic reaction and is seizing, what should be administered?

1. Glucose gel

2. 50% dextrose IV

3. Oral potassium

4. Adrenaline injection

The correct answer is: 50% dextrose IV

Administering 50% dextrose IV is the appropriate response in the event of a hypoglycemic reaction accompanied by seizures. This response is critical because hypoglycemia can lead to severe neurological impairment, including seizures, due to insufficient glucose supply to the brain, which relies on glucose as its primary energy source. Intravenous dextrose provides a rapid and direct way to elevate blood glucose levels, quickly addressing the underlying cause of the patient's condition. The concentrated solution allows for prompt absorption into the bloodstream, thereby increasing the glucose levels more effectively than other methods, especially if the patient is unable to take oral medications due to the ongoing seizure. The other options, while potentially useful in different contexts, do not address the immediate need for raising blood sugar levels as effectively. For instance, glucose gel would not be suitable during a seizure, as the patient may not be able to swallow or protect their airway. Oral potassium does not relate to hypoglycemia; it is more relevant in cases of hyperkalemia or conditions affecting potassium balance. Adrenaline injections are typically used for anaphylaxis or severe asthma attacks and would not counteract the effects of hypoglycemia. Thus, intravenous 50% dextrose is the most effective and appropriate
