    Anorexic Ava — Anorexia Nervosa: Starvation, Bradycardia & Refeeding Syndrome

    She is freezing in a warm room, her heart beats in the 40s — and the danger begins the moment she starts eating again

    Anorexic Ava, the MnemoNurse character for Anorexia Nervosa: Starvation, Bradycardia & Refeeding Syndrome

    Ava is admitted with a heart rate of 42 and a temperature of 96.1. She insists she is fine. On day two of nutrition her phosphorus falls and the monitor starts to change.

    Ava restricts her intake because of an intense fear of gaining weight and a distorted body image, even though her weight is dangerously low. Starvation slows the whole body: bradycardia, hypotension, hypothermia, amenorrhea, dry skin and fine lanugo hair. The exam's favorite twist is refeeding syndrome — when nutrition restarts, insulin rises and drives phosphorus, potassium and magnesium into the cells, dropping serum levels fast enough to cause dysrhythmias, heart failure and seizures. Calories are restarted slowly with daily electrolyte monitoring.

    The story arc

    1. The setup

      Ava is admitted after fainting at school. She is wrapped in two blankets, wears baggy clothes, and tells the nurse she 'already ate.'

    2. The turn

      Her heart rate sits in the 40s, her blood pressure drops when she stands, and her potassium comes back low.

    3. The crisis

      Two days after nutrition is restarted, Ava becomes confused and weak, and her phosphorus, potassium and magnesium have all fallen.

    4. The save

      The team slows the calorie advance, replaces electrolytes, monitors her heart continuously, and a dietitian and therapist join her plan with supervised meals and bathroom monitoring.
