In a hypoglycemic emergency, which action is the best initial step for an unresponsive patient?

• A. Open airway and assess breathing
• B. Check for a medical identification tag
• C. Administer 100% oxygen via nonrebreathing mask
• D. Administer oral glucose between cheek and gum

Answer: (A)

In an unresponsive person with a suspected hypoglycemic event, the first priority is the airway and breathing. Ensuring a clear airway and confirming that the person is ventilating is essential because without enough oxygen, brain damage can occur quickly. Oral glucose is only appropriate if the patient is conscious and able to swallow, so giving it to someone who is unresponsive risks choking or aspiration and won’t address any breathing problems. Checking for a medical ID tag is helpful for diagnosis but doesn’t save the person’s life in the moment. Oxygen therapy is important only if there’s inadequate breathing or proven hypoxia, but you don’t initiate it before confirming the airway and breathing status. Once you’ve opened the airway and confirmed they’re breathing, you can proceed with the appropriate next steps based on their responsiveness.
