Question 1

Which of the following represents the typical profile of a patient with either anorexia nervosa or bulimia nervosa?

Accepted Answer

Anorexia nervosa and bulimia nervosa are more common among young females, especially those who are in socially competitive environments such as those involving sports, modeling or dance. While depression may be a factor, it is not necessarily a typical profile for these disorders. Bulimia can also affect males and females in their mid to late twenties. Lack of friends is not a determining factor for these disorders. Therefore, choice A is the most accurate answer.

Question 2

Individuals who experience loss of control of their eating and consume great quantities of food but do not engage in any attempts to compensate for their binge would be diagnosed with

Accepted Answer

Individuals who experience loss of control of their eating and consume great quantities of food but do not engage in any attempts to compensate for their binge would be diagnosed with binge eating disorder.

Question 3

When individuals with anorexia nervosa have been evaluated over long periods of time, it has been found that the percentage of individuals who die as a result of their disorder is ____.

Accepted Answer

The mortality rate for individuals with anorexia nervosa over long periods of time is approximately 20%. This high rate reflects the serious health risks associated with the disorder, including complications from starvation, metabolic disturbances, and the potential for suicide.

Question 4

Which of the following statements is true?

Accepted Answer

According to research, over 80% of people with bulimia had an anxiety disorder at some point in their lives. Option A is incorrect because although eating disorders can co-occur with depression, they are not always an expression of depression. Option B is incorrect because although there is a high co-occurrence of eating disorders and PTSD, it is not specifically with bulimia. Option D is incorrect because the percentage of people with bulimia who meet the criteria for a mood disorder during the course of their eating disorder is higher, at around 50 to 70%.

Question 5

The males most likely to develop an eating disorder such as bulimia nervosa are those who are

Accepted Answer

Research has shown that homosexual and bisexual males are at a higher risk for developing eating disorders such as bulimia nervosa than heterosexual males. This may be due to societal pressure to conform to certain body ideals within the LGBTQ+ community. Overweight and depression may contribute to the development of an eating disorder, but they are not exclusive risk factors. Being an only child has not been found to be a significant risk factor for developing an eating disorder.

Question 6

Most individuals with bulimia nervosa

Accepted Answer

Purging by self-induced vomiting is the most common form of purging behavior in individuals with bulimia nervosa, as it allows them to rid their bodies of the calories and guilt associated with binge eating. While exercise and fasting may also be used as compensatory measures, they are not as common as vomiting.

Question 7

As many as ____ of anorexia nervosa deaths are due to suicide.

Accepted Answer

Research suggests that up to 20% to 30% of individuals who suffer from anorexia nervosa may die by suicide, making it the primary cause of death associated with this eating disorder.

Question 8

The chief motivating factor in both anorexia nervosa and bulimia nervosa is

Accepted Answer

Both anorexia nervosa and bulimia nervosa are primarily characterized by an intense fear of gaining weight and a desire to be thin. This drive to achieve an unrealistic thinness is the chief motivating factor behind these disorders, leading to behaviors such as restrictive eating, excessive exercise, and purging. While the other options may play a role in some cases, they are not the primary underlying motivators for these disorders.

Question 9

Eating disorders are most prevalent in

Accepted Answer

Eating disorders are most prevalent in Western cultures where food is plentiful due to the widespread availability of high-energy foods and a cultural emphasis on thinness as a symbol of beauty and success. While eating disorders can occur in non-Western cultures, they are less prevalent due to different cultural values and attitudes towards food and body image.

Question 10

Amy is a young woman who is very competitive and comes from a high-achieving, wealthy family. She is very social and likes the fact that she is quite popular. She believes that her popularity is dependent on the weight and shape of her body. Amy has a boyfriend but worries that she may care more about their relationship than he does. The feature that puts Amy most at risk for an eating disorder is her

Accepted Answer

Amy's belief that her popularity is dependent on her weight and shape puts her at risk for developing an eating disorder such as anorexia or bulimia. This belief can lead to a preoccupation with body weight, restrictive dieting, and excessive exercise in an effort to maintain or achieve a certain body shape or weight. Amy's competitive nature and successful family may also contribute to feelings of pressure and perfectionism, which can exacerbate the risk of developing an eating disorder. However, A is the most significant risk factor based on the information provided.

Question 11

Recent research suggests that the restricting and bingeing/purging subtypes of anorexia nervosa

Accepted Answer

Recent research indicates that the restricting and bingeing/purging subtypes of anorexia nervosa show few differences in severity of symptoms or personality, suggesting that these subtypes may not be as distinct as previously thought.

Question 12

The most common reason that people with anorexia nervosa generally do not seek treatment on their own is that they

Accepted Answer

People with anorexia nervosa often do not recognize or admit that they are too thin, which is a significant barrier to seeking treatment. They may see themselves as overweight or of normal weight despite being underweight, leading to a lack of perceived need for treatment.

Question 13

Susan, a woman of relatively normal weight, sometimes eats huge quantities of junk food with no ability to stop herself. She follows this with long periods of complete fasting. Based on this information, Susan would

Accepted Answer

Susan exhibits symptoms of binge eating followed by fasting, which are key features of bulimia nervosa. Purging (such as vomiting or laxative use) is not required for a diagnosis of bulimia nervosa. Additionally, one can have a normal weight and still be diagnosed with an eating disorder.

Question 14

Jody sometimes eats more than just about any other girl that you know. You wonder if her eating sometimes could be considered bingeing. In order to determine this, you would have to know

Accepted Answer

The defining feature of binge eating is that it involves eating in an uncontrollable manner, regardless of the types or amounts of food consumed. Thus, in order to determine if Jody's eating could be considered bingeing, it would be most important to assess whether she feels out of control while she eats.

Question 15

A binge-eating episode is characterized by food intake of at least how many calories?

Accepted Answer

The number of calories consumed during a binge-eating episode can vary from person to person and is not a defining factor in diagnosing binge eating disorder. It is more important to focus on the psychological and behavioral aspects of the disorder.

Question 16

The approximate percentage of patients with eating disorders who will experience depression at some point in their lives is approximately ____.

Accepted Answer

Research studies show that approximately 71% of individuals with eating disorders experience depression at some point in their lives. Depression can often lead to increased symptoms of the eating disorder, making it important to address both simultaneously in treatment.

Question 17

The hallmark of anorexia nervosa is

Accepted Answer

The hallmark of anorexia nervosa is a morbid fear of gaining weight and relentlessly pursuing thinness. While food refusal and a low weight are often present, they are not unique to anorexia nervosa and can be present in other eating disorders as well. The binge-purge cycle is a characteristic of bulimia nervosa, not anorexia nervosa.

Question 18

Since about 1960, most Westernized countries have experienced a dramatic

Accepted Answer

Most Westernized countries have experienced an increase in the incidence of anorexia nervosa and bulimia nervosa since 1960, likely due to increased societal pressure to meet unrealistic beauty standards and a rise in diet and fitness culture. However, it's worth noting that there has been some variation in the prevalence of these disorders across different countries and time periods.

Question 19

Which of the following statements is true regarding the effectiveness of purging for reducing caloric intake?

Accepted Answer

Vomiting reduces approximately 50% of calories consumed, but the effectiveness decreases if delayed after eating. Laxatives do not reduce calories as they do not prevent absorption in the small intestine, so option B is incorrect. Option A is incorrect as vomiting does not reduce almost 100% of calories consumed even if done immediately after eating.

Question 20

Patients with bulimia nervosa often present with additional psychological disorders, particularly ________ and ________.

Accepted Answer

Patients with bulimia nervosa commonly have co-occurring anxiety disorders and mood disorders. These can include generalized anxiety disorder, panic disorder, and major depressive disorder. While substance disorders and body dysmorphic disorder may also be present, they are not as common as anxiety and mood disorders. Sexual disorders and obsessive-compulsive disorder may also occur, but with less frequency than anxiety and mood disorders.
