A.

Metabolism

B.

Anabolism

C.

Catabolism

D.

Health promotion

Answer and Explanation

The Correct Answer is A

A. Metabolism

Metabolism is the sum of all chemical reactions in the body that maintain life, including those that break down nutrients for energy and those that build new cellular components.


 

B. Anabolism

Anabolism refers to the building up of complex molecules from simpler ones (e.g., protein synthesis), but it is just one part of overall metabolism.

C. Catabolism

Catabolism is the breakdown of molecules to release energy (e.g., digestion), but it’s also just one half of metabolism.

D. Health promotion

Health promotion refers to activities that improve health and prevent disease, not chemical changes in the body.

Correct Answer is B

Explanation

A. Storing bile

Bile is stored in the gallbladder, not the small intestine.

B. Digesting/absorbing food

The small intestine is the primary site for digestion and absorption of nutrients. A large resection would significantly impair these functions, leading to malabsorption.

C. Producing chyme

Chyme is produced in the stomach, not the small intestine.

D. Secreting pepsin

Pepsin is secreted by the stomach, not the small intestine.

Correct Answer is B

Explanation

A. "You must try medication and diet changes for at least two years before surgery is considered.”

The OMA and ASMBS guidelines recommend considering bariatric surgery in patients with a BMI ≥30 with comorbidities like type 2 diabetes when lifestyle and medical therapies are insufficient. There is no strict 2-year requirement.

B. "You may be a candidate for bariatric surgery because of your BMI and type 2 diabetes."

The OMA supports considering bariatric surgery for individuals with a BMI ≥30 who also have comorbidities like type 2 diabetes, especially if other treatments have failed.

C. "Bariatric surgery is only recommended for individuals with a BMI of 40 or higher."

Surgery is also considered for patients with a BMI ≥35 with comorbidities, and in some cases, ≥30 with significant health issues like diabetes.

D. "Bariatric surgery is not appropriate for people under the age of 30."

Age alone is not a disqualifier for bariatric surgery. Candidates are evaluated on BMI, comorbidities, and failure of other treatments.
