A nurse is collecting data for a health history from a client who has bulimia nervosa. Which of the following laboratory findings should the nurse expect?

Choice A reason: Hypokalemia, or low potassium levels in the blood, is a common finding in individuals with bulimia nervosa, especially those who engage in frequent vomiting or use laxatives. Purging behaviors can lead to significant electrolyte imbalances, including potassium depletion, which can cause muscle weakness, cramps, and cardiac arrhythmias. Monitoring potassium levels is crucial in managing the health of individuals with bulimia nervosa. Choice B reason: Leukopenia, or a low white blood cell count, is not typically associated with bulimia nervosa. While malnutrition and other complications of eating disorders can affect the immune system, leukopenia is more commonly linked to conditions such as infections, autoimmune disorders, or certain medications. Choice C reason: Decreased serum amylase is not a typical finding in bulimia nervosa. In fact, elevated serum amylase levels are more commonly observed due to the stress on the salivary glands from frequent vomiting. Hyperamylasemia can be an indicator of purging behaviors and should be monitored in individuals with bulimia nervosa. Choice D reason: Hematuria, or the presence of blood in the urine, is not commonly associated with bulimia nervosa. While hematuria can result from various conditions, including urinary tract infections, kidney stones, or other renal issues, it is not a typical finding in individuals with bulimia nervosa.
