A nurse is collecting data from a client who has anorexia nervosa. Which of the following findings should the nurse identify as a positive outcome of treatment?

A. The client's potassium level is 2.7 mEq/L is incorrect. A potassium level of 2.7 mEq/L is low and indicates hypokalemia, which is a life-threatening condition that can occur in anorexia nervosa, particularly if the client is engaging in behaviors like purging. This level should be addressed immediately, not considered a positive outcome. B. The client resumes menstruation is correct. The resumption of menstruation is a positive outcome of treatment for anorexia nervosa. It indicates that the client's nutritional status has improved and that the body is starting to regain normal function after addressing issues like malnutrition and hormonal imbalances. C. The client's pulse rate is 44/min is incorrect. A pulse rate of 44/min is bradycardia, which is a common sign of anorexia nervosa due to malnutrition and the body's attempt to conserve energy. While it may improve with treatment, this finding would not be considered a positive outcome. D. The client develops lanugo is incorrect. Lanugo (fine, soft hair) typically develops in severe anorexia nervosa due to malnutrition and is a sign of starvation. The appearance of lanugo is not a positive outcome but rather a compensatory mechanism to retain heat, indicating that the client is still in a malnourished state.
