Question 1

Use the information below to answer questions 
In 2007, Swedish researchers published results from a study in which they followed about 2000 obese patients who had undergone weight-loss surgery-either gastric bypass or surgical banding-over 15 years and compared them with about 2000 similarly obese people who didn't have surgery but who were counseled in diet and exercise. One goal of the study was to determine whether bariatric surgery led to greater weight loss than diet and exercise counseling.
-In this study,the control group was made up of _________.

Accepted Answer

The control group in the study was made up of about 2000 similarly obese people who did not have surgery but were counseled in diet and exercise.

Question 2

How does gastric banding surgery differ from gastric bypass surgery?

Accepted Answer

The answer of How does gastric banding surgery differ from...

Question 3

A person who has had her gallbladder removed will need to limit the amount of which macromolecule in her diet?

Accepted Answer

The gallbladder is responsible for storing bile that helps in the breakdown and absorption of fats. Without a gallbladder, the liver still produces bile, but it cannot be stored and released in response to meals. Therefore, a person who has had her gallbladder removed will need to limit the amount of fats in her diet to reduce digestive symptoms such as diarrhea and abdominal pain.

Question 4

Weight-loss surgery has _________.

Accepted Answer

Weight-loss surgery has been shown to significantly reduce the risk of death compared to remaining obese. It can also potentially improve or resolve health conditions associated with obesity such as diabetes and high blood pressure.

Question 5

Gastric banding is _________ than gastric bypass surgery.

Accepted Answer

Gastric banding is somewhat less effective than gastric bypass surgery, but it is more easily reversible.

Question 6

The following five questions  require interpretation of the graph below:
 
-The graph illustrates some of the study's results.From it,you can conclude that _________.

Accepted Answer

The graph shows the percentage of initial body weight lost by patients who underwent gastric banding or gastric bypass at different points in time. At the end of 15 years, the gastric banding group had lost about 15% of their initial body weight, while the gastric bypass group had lost about 25%, making option B the correct choice. Option A is incorrect because the graph shows percentage of weight lost, not actual pounds lost. Option C is incorrect because the graph does not indicate weight regain. Option D is incorrect because the control group is not mentioned in the graph or the given information.

Question 7

The following five questions  require interpretation of the graph below:
 
-The graph illustrates some of the study's results.The vertical lines at each data point are called error bars.As a general rule,when the error bars from two different data points or lines overlap,we can conclude that the two points or lines are not significantly different from one another.Or,put another way,we can conclude that any difference we see is due to chance,not to any real difference in the data.Given this information,which of the following best describes the results?

Accepted Answer

The error bars for the gastric bypass group do not overlap with those of the two banding groups or the control group, indicating that the weight loss in the gastric bypass group is significantly different from that of the other groups. However, the error bars for the two banding groups and the control group overlap, indicating that there is no significant difference in weight loss between those three groups.

Question 8

Gastric banding surgery is __________.

Accepted Answer

Gastric banding surgery is similar to gastric bypass surgery in that it reduces the size of the stomach, but it uses a removable band to achieve this instead of permanently rerouting the digestive system. The other options either include incorrect information or are too general.

Question 9

Traditional gastric bypass surgery __________,whereas gastric banding __________. reduces the volume of the stomach
Prevents food from entering the upper part of the small intestine
Allows food to pass through the stomach normally

Accepted Answer

Traditional gastric bypass surgery reduces the volume of the stomach and prevents food from entering the upper part of the small intestine, while gastric banding only reduces the volume of the stomach and allows food to pass through the stomach normally. Therefore, statement I is true for both procedures, statement II is true only for gastric bypass surgery, and statement III is true only for gastric banding. Choice A accurately reflects this information.

Question 10

The following two questions  require interpretation of the graph below:
 
-Interpret the data in the graph.

Question 11

The following two questions  require interpretation of the graph below:
 
-In 2007,Swedish researchers published results from a study in which they followed about 2000 obese patients who had undergone weight-loss surgery-either gastric bypass or surgical banding-over 15 years and compared them with about 2000 similarly obese people who didn't have surgery but who were counseled in diet and exercise.One goal of the study was to determine whether bariatric surgery saved lives as a consequence of reducing patients' weights.This graph illustrates some of their results.Based on these results and what you know about the pros and cons of bariatric surgery,would you recommend it as a good treatment for morbid obesity? Explain.

Accepted Answer

The answer of The following two questions  require interpretation...

Question 12

Both gastric bypass and gastric banding surgery lead to weight loss by reducing the number of calories a person absorbs from his food.Gastric bypass surgery accomplishes this by __________.

Accepted Answer

Gastric bypass surgery both reduces the volume of food the stomach can hold (as the stomach is made smaller) and reduces the amount of nutrients absorbed by the small intestine (as a portion of the small intestine is bypassed).

Question 13

The following five questions  require interpretation of the graph below:
 
-Which group regained the most weight 15 years after the surgery?

Accepted Answer

Question 15

Both gastric bypass and gastric banding surgery lead to weight loss by reducing the number of calories a person absorbs from her food.Gastric banding surgery accomplishes this by __________.

Accepted Answer

Gastric banding surgery reduces the volume of food the stomach can hold by placing a band around the upper part of the stomach, creating a small pouch. This limits the amount of food a person can eat, leading to a reduction in calorie intake and weight loss. Gastric bypass surgery, on the other hand, reduces calorie absorption by rerouting food to bypass a section of the small intestine.

Question 16

Does food bypass the stomach after gastric bypass surgery? Explain.

Question 17

Use the information below to answer questions 
In 2007, Swedish researchers published results from a study in which they followed about 2000 obese patients who had undergone weight-loss surgery-either gastric bypass or surgical banding-over 15 years and compared them with about 2000 similarly obese people who didn't have surgery but who were counseled in diet and exercise. One goal of the study was to determine whether bariatric surgery led to greater weight loss than diet and exercise counseling.
-In this study,the independent variable was ________,and the dependent variable was _________.

Accepted Answer

The independent variable in this study was the intervention, which was either surgery or diet/exercise counseling. The dependent variable was weight loss, as this was the outcome that the researchers were measuring and comparing between the two groups. Therefore, choice A is the correct answer.

Question 18

The following five questions  require interpretation of the graph below:

...

Question 20

Beside most of the stomach,the part of the digestive system that is bypassed in a gastric-bypass procedure is the _________.

Accepted Answer

The duodenum is the first part of the small intestine and is bypassed in a gastric-bypass procedure. This means that food does not enter the duodenum and instead goes directly into the jejunum, the second part of the small intestine. This can lead to changes in the absorption of nutrients and contribute to weight loss. The esophagus, colon, appendix, and liver are not bypassed in this procedure.
