A nurse is caring for a female client who has bulimia nervosa and reports frequent self-induced vomiting. Which of the following findings should the nurse expect?

A. Hyperkalemia is incorrect. Frequent vomiting causes loss of gastric acid and potassium, leading to hypokalemia, not hyperkalemia. Hypokalemia can result in muscle weakness, arrhythmias, and fatigue. B. Lower than normal expected reference range of body weight is more characteristic of anorexia nervosa. Clients with bulimia typically maintain a normal weight or may fluctuate slightly above or below normal. Severe underweight is less common. C. Dental decay is correct. Repeated exposure of the teeth to stomach acid from vomiting erodes enamel, leading to dental erosion, sensitivity, and increased cavities, making dental problems a hallmark physical finding in bulimia nervosa. D. Amenorrhea is more associated with anorexia nervosa due to extreme weight loss and hormonal disruption. Although menstrual irregularities can occur in bulimia, they are less consistent than in anorexia.
