A 56-yeаr-оld wоmаn presents with sudden оnset of pаlpitations, trembling, sweating, anxiety, headache, and confusion that started 1 hour ago after a 5-mile early morning run. She has had similar episodes in the past, but never any symptoms this severe. Sometimes she wakes up in the morning with headaches and trembling, but they usually go away after she has gotten ready and has breakfast. On physical exam, she is found to have heart rate 114, blood pressure 125/86, respiration rate 18, weight 160 lb, and temperature 98.7°F. Patient is alert and appears somewhat anxious and diaphoretic but otherwise well. HEENT exam is unremarkable. Cranial nerves, cerebellar function, strength, sensation, deep tendon reflexes, and balance testing/Romberg are all normal. Patient is tachycardic, but S1 and S2 are normal with no murmurs, rubs, or gallops. Lungs are clear to auscultation bilaterally. EKG shows sinus tachycardia. Lab work is significant for a glucose level of 36. What would be most likely if the patient's low blood glucose was due to accidental, surreptitious, or malicious administration of exogenous insulin such as glargine (Lantus)?
