CBE Preoperative Education & Patient Selection 2 — Questions and Answers
Question 1: Which preoperative laboratory workup is most critical for identifying nutritional deficiencies before bariatric surgery?
- Complete blood count only
- Thyroid function panel only
- Comprehensive nutritional panel including vitamins and minerals (Correct answer)
- Basic metabolic panel only
Correct answer: Comprehensive nutritional panel including vitamins and minerals
A comprehensive nutritional panel detects existing deficiencies that must be corrected preoperatively to prevent worsening after surgery alters absorption.
Question 2: How far in advance of bariatric surgery should a patient ideally achieve smoking cessation?
- 1 week before surgery
- The night before surgery
- At least 4–8 weeks before surgery, ideally 6 months (Correct answer)
- Smoking cessation is only recommended, not required
Correct answer: At least 4–8 weeks before surgery, ideally 6 months
Smoking cessation at least 4–8 weeks before surgery significantly reduces risks of pulmonary complications, anastomotic leaks, and impaired wound healing.
Question 3: Which patient behavior is the best indicator of readiness for bariatric surgery?
- Attending required appointments but continuing the same eating habits
- Demonstrating consistent dietary changes and full attendance at preoperative visits (Correct answer)
- Losing 50 lbs independently through dieting before the surgery date
- Having strong family pressure encouraging them to undergo the procedure
Correct answer: Demonstrating consistent dietary changes and full attendance at preoperative visits
Consistent behavioral changes prior to surgery are the strongest predictor of long-term postoperative compliance and successful weight management.
Question 4: What is the primary purpose of the preoperative low-calorie liquid diet typically prescribed 2–4 weeks before bariatric surgery?
- To test the patient's willpower and discipline
- To reduce liver size and improve laparoscopic surgical access (Correct answer)
- To achieve maximum body weight loss before the procedure
- To simulate the dietary pattern required after surgery
Correct answer: To reduce liver size and improve laparoscopic surgical access
A low-calorie liquid diet reduces hepatic steatosis, shrinking the enlarged fatty liver and improving the surgeon's laparoscopic access to the stomach.
Question 5: When educating a patient about dumping syndrome preoperatively, which key message should be emphasized?
- It only occurs with gastric bypass and cannot be managed once it starts
- It can be minimized by eating small, frequent meals and avoiding high-sugar foods (Correct answer)
- It is a temporary side effect that resolves completely within the first week
- Every episode requires immediate emergency department evaluation
Correct answer: It can be minimized by eating small, frequent meals and avoiding high-sugar foods
Dietary modifications—small frequent meals and avoidance of high-sugar, high-fat foods—significantly reduce the frequency and severity of dumping syndrome.
Question 6: Which statement most accurately describes informed consent for bariatric surgery?
- Informed consent is complete once the patient signs the consent form
- Informed consent must include risks, benefits, alternatives, and realistic expected outcomes (Correct answer)
- Informed consent is solely the surgeon's legal responsibility
- Informed consent is only required for patients covered by Medicare
Correct answer: Informed consent must include risks, benefits, alternatives, and realistic expected outcomes
Complete informed consent requires that patients understand and acknowledge the procedure's risks, benefits, alternatives, and realistic expectations before agreeing to surgery.
Question 7: What role does the bariatric educator play in helping patients navigate insurance authorization?
- The educator has no role in insurance matters
- The educator helps patients gather required documentation such as diet records and medical history (Correct answer)
- The educator directly contacts insurers to negotiate surgical coverage on the patient's behalf
- The educator determines whether a patient qualifies for insurance coverage
Correct answer: The educator helps patients gather required documentation such as diet records and medical history
While educators do not make insurance decisions, they assist patients in understanding requirements and compiling necessary documentation to support authorization requests.
