In assessment of hypoglycemia, which finding is most likely?

• A. Combativeness
• B. Pale, cool skin
• C. Slow breathing
• D. Drowsiness and confusion

Answer: (A)

Low blood glucose disrupts brain function, so early signs come from the body's adrenaline response and the brain struggling to use glucose. The most common behavior you’ll see is agitation or combativeness as the patient becomes irritable and combative from neuroglycopenia. This reflects the brain’s need for glucose and the body’s attempt to wake it up. Other signs like pale, cool skin can occur but are less specific, slow breathing isn’t typical of hypoglycemia, and drowsiness or confusion tends to appear later as glucose levels drop further. In practice, when you suspect hypoglycemia, check a blood glucose and treat promptly: give oral glucose if the patient can swallow and is conscious, or use IV dextrose or glucagon if they cannot protect their airway or are unconscious.
