A 16-year-old girl presents with peptic ulcers, constipation, low self-esteem, irregular menstrual cycle, and dental erosion. Her weight has fluctuated between 96 and 128 pounds over the past year. The nurse suspects the girl is suffering from

  1. binge eating disorder.
  2. bulimia nervosa.
  3. pernicious anemia.
  4. anorexia nervosa.
Number 2 is correct.
Rationale: Signs and symptoms of bulimia nervosa include peptic ulcers, constipation, low self-esteem, irregular menstrual cycle, and dental erosion. Gastric reflux, electrolyte imbalance, swollen salivary glands, and depression may also be seen. A client with bulimia nervosa may have a normal weight, but can also be underweight or overweight depending on diet, exercise, and binge habits.
