These assessment findings are most consistent with the medical diagnosis of:
Correct Answer: B
Rationale: The correct answer is B: Anorexia nervosa. The assessment findings align with the diagnostic criteria for anorexia nervosa, including significant weight loss, restrictive eating patterns, distorted body image, amenorrhea, and physical signs like poor skin turgor and lanugo. The patient's extreme weight loss, restrictive calorie intake, dissatisfaction with weight despite being underweight, and other physical and psychological symptoms are classic indicators of anorexia nervosa.
Incorrect Choices:
A: Bulimia nervosa involves binge eating followed by compensatory behaviors, which are not evident in this case.
C: Binge-eating disorder involves recurrent episodes of binge eating without compensatory behaviors, which are not present here.
D: Disturbed body image may be present in anorexia nervosa, but the key features of weight loss, restrictive eating, and amenorrhea are more indicative of anorexia nervosa.
