Final answer:
Diagnostic tests for eating disorders include blood pressure measurements, bone density scans, and dental check-ups to detect signs of physical complications associated with anorexia nervosa or bulimia nervosa.
Step-by-step explanation:
The diagnostic tests that may be used in the diagnosis of an eating disorder include blood pressure measurement, bone density scan, and dental check-up. Blood pressure measurement helps in detecting electrolyte imbalances that are common in disorders like bulimia nervosa. A bone density scan is used to check for signs of osteoporosis, which may occur due to malnutrition associated with anorexia nervosa. Dental check-ups can reveal enamel erosion or tooth decay, which are signs that may be present in individuals with bulimia nervosa due to repeated vomiting. Eye color examination is not a diagnostic test for eating disorders. Eating disorders like anorexia nervosa, bulimia nervosa, and binge-eating disorder can have serious consequences on physical and mental health, and thus, it is crucial to diagnose and treat them properly.
