Scenаriо 11 | Mild Hypоcаlcemiа A 21-year-оld college student presents to the clinic after experiencing intermittent episodes of muscle twitching and brief tingling sensations in his hands and feet over the past several weeks. He reports that the symptoms are more noticeable during periods of stress and after consuming large amounts of caffeine. He denies any loss of consciousness or weakness but notes that his reflexes feel “more jumpy” than usual. On neurological examination, muscle strength is normal, but there is mild hyperreflexia and occasional spontaneous muscle fiber twitches. Sensory testing reveals heightened sensitivity to light touch in the fingertips. Laboratory results show slightly decreased plasma calcium levels, while other electrolytes are within normal limits. The clinician explains that calcium plays an important role in stabilizing neuronal and muscle membrane excitability by influencing the threshold for action potential generation. A decrease in extracellular calcium lowers the threshold for voltage-gated sodium channel activation, increasing the likelihood of spontaneous depolarization in both peripheral nerves and skeletal muscle fibers.

Scenаriо 2 | Pооrly Controlled Type 1 Diаbetes A 19-yeаr-old college athlete with a history of type 1 diabetes mellitus presents to the emergency department with confusion, abdominal pain, and rapid breathing. His roommate reports he has been ill with a respiratory infection and has not been taking insulin regularly. On exam, he is dehydrated, tachycardic (elevated HR), and breathing deeply and rapidly. Laboratory studies reveal hyperglycemia, ketonemia (elevated blood ketones), and slightly acid blood pH. Upon being admitted, he is given 0.9% NaCl saline solution in his IV.
