Question 4: What is the primary purpose of the pre-operative liquid diet prescribed before bariatric surgery?
- Reduce operative time
- Shrink the liver to improve surgical access (Correct answer)
- Eliminate the need for general anesthesia
- Prevent post-operative nausea
Correct answer: Shrink the liver to improve surgical access
The pre-operative liquid diet reduces liver glycogen and fat stores, shrinking the liver and improving the surgeon's access to the stomach.

- IQ testing
- Psychiatric clearance to assess mental health readiness (Correct answer)

A psychiatric or psychological evaluation is required to assess a patient's mental health, motivation, and readiness to comply with post-surgery lifestyle changes.

- Colonoscopy
- CT scan of the abdomen
- Upper endoscopy (EGD) (Correct answer)

Correct answer: Upper endoscopy (EGD)
Upper endoscopy (esophagogastroduodenoscopy) allows direct visualization of the esophagus and stomach to detect ulcers, hiatal hernias, or H. pylori before surgery.
Question 7: Which of the following conditions is generally considered an absolute contraindication for bariatric surgery?
- Controlled type 2 diabetes
- Uncontrolled substance abuse disorder (Correct answer)
