Final answer:
Psychosis is a mental health condition where a person experiences a loss of contact with reality, which is not the same as bulimia nervosa, an eating disorder characterized by binge eating and purging (c).
Step-by-step explanation:
A disorder in which a person loses contact with reality and experiences irrational ideas and disordered perceptions is known as psychosis. This mental health condition is characterized by symptoms such as hallucinations, delusions, and incoherent thought processes, which significantly impair an individual's ability to function. Psychosis is a symptom rather than a diagnosis in itself and can occur within the context of several psychiatric illnesses, including schizophrenia and bipolar disorder.
Bulimia nervosa, on the other hand, is an eating disorder marked by recurrent episodes of binge eating followed by compensatory behaviors to avoid weight gain such as self-induced vomiting, misuse of laxatives or diuretics, fasting, or excessive exercise. People with bulimia nervosa may have a normal or fluctuating weight range, and it is not characterized by loss of contact with reality as seen in psychosis. Co-occurrence of eating disorders, like bulimia nervosa or anorexia nervosa, with body dysmorphic disorder is common.
