Easy
Which description best defines obesity as recognized in medical literature?
Excess accumulation of body fat that may compromise health
A psychological state characterized by emotional overeating
A condition solely determined by genetic predisposition with no lifestyle factors
A temporary weight gain due to dietary indiscretion
The correct answer emphasizes that obesity involves an excess accumulation of body fat that can lead to health complications. This definition is widely accepted in medical literature, unlike the other options which misrepresent the chronic and multifactorial nature of obesity.
In a multidisciplinary preoperative assessment for bariatric surgery, which professional's role is most vital for evaluating nutritional status and dietary habits?
Registered Dietitian
Physical Therapist
Radiologist
Anesthesiologist
A registered dietitian is crucial in assessing a patient's nutritional status and guiding dietary modifications before surgery. The other professionals contribute to different aspects of preoperative evaluation but do not primarily focus on nutritional assessment.
Which bariatric surgical procedure involves creating a small stomach pouch and rerouting the small intestine?
Roux-en-Y Gastric Bypass
Adjustable Gastric Banding
Vertical Sleeve Gastrectomy
Biliopancreatic Diversion
Roux-en-Y gastric bypass involves creating a small pouch from the stomach and rerouting the small intestine, thereby limiting both food intake and absorption. The other procedures work through different mechanisms and do not include both pouch creation and intestinal rerouting.
Which of the following is most important for sustaining weight loss and overall health after bariatric surgery?
Lifelong dietary changes and regular physical activity
Immediate postoperative medication use
Strict bed rest during recovery
Avoidance of follow-up appointments
Adopting lifelong dietary modifications and regular physical activity is key to maintaining weight loss and improving overall health after bariatric surgery. Other options either focus on short-term measures or detrimental practices not conducive to long-term success.
Which factor is commonly implicated in the pathophysiology of obesity?
Insulin resistance
Hypothyroidism only
Acute inflammation
Decreased cortisol levels
Insulin resistance is a well-recognized factor that contributes significantly to the development of obesity and its associated metabolic dysfunction. While other conditions may influence weight, they are not as commonly implicated in the primary pathogenesis of obesity.
Medium
Which cytokine is often elevated in obesity and contributes to chronic low-grade inflammation?
TNF-alpha
Interferon-gamma
Erythropoietin
Brain-derived neurotrophic factor
TNF-alpha is a pro-inflammatory cytokine that is commonly elevated in the state of obesity, contributing to insulin resistance and chronic inflammation. The other options are either associated with different physiological processes or are not primarily linked to obesity-related inflammation.
Which preoperative evaluation is most critical to identify potential cardiac risks before bariatric surgery?
Comprehensive cardiac evaluation including stress testing
Routine dental examination
Pulmonary function tests
Abdominal ultrasound
A comprehensive cardiac evaluation, often including stress testing, is essential in identifying underlying heart conditions that could complicate bariatric surgery. While pulmonary and other evaluations are important, they do not directly assess cardiac risk.
Which factor is considered a contraindication to performing bariatric surgery?
Active, untreated psychiatric illness impairing decision-making
Controlled type 2 diabetes
Obesity-related hypertension
History of failed weight loss attempts
Active, untreated psychiatric illnesses can jeopardize postoperative adherence and affect outcomes, making them a contraindication to bariatric surgery. The other conditions, when properly managed, do not usually preclude a patient from surgical intervention.
Which surgical procedure primarily restricts stomach volume without significantly altering gastrointestinal anatomy?
Adjustable Gastric Banding
Vertical Sleeve Gastrectomy
Roux-en-Y Gastric Bypass
Biliopancreatic Diversion
Adjustable gastric banding limits the stomach's capacity by using a band without making permanent anatomical changes to the gastrointestinal tract. In contrast, procedures like the vertical sleeve gastrectomy and Roux-en-Y gastric bypass involve irreversible alterations.
Which of the following is a common postoperative complication specific to bariatric surgery, particularly after procedures like gastric bypass?
Dumping syndrome
Wound dehiscence
Deep vein thrombosis
Pulmonary embolism
Dumping syndrome is a well-recognized complication of bariatric surgeries such as the Roux-en-Y gastric bypass, where rapid gastric emptying leads to symptoms like nausea and dizziness. The other complications, although possible, are not as specifically associated with bariatric procedures.
How does bariatric surgery contribute to the improvement of type 2 diabetes?
Through hormonal changes and rapid weight loss that improve insulin sensitivity
By directly removing the pancreas
By increasing carbohydrate absorption in the intestines
By reducing physical activity demands
Bariatric surgery improves type 2 diabetes mainly through significant weight loss and hormonal changes, including increased incretin secretion, which together enhance insulin sensitivity and glycemic control. The other options do not accurately describe the metabolic mechanisms involved.
Which preoperative test is most valuable in assessing sleep apnea in obese patients being considered for bariatric surgery?
Polysomnography
Electrocardiogram (ECG)
Chest X-ray
Complete blood count (CBC)
Polysomnography is the gold standard diagnostic test for sleep apnea, a condition commonly associated with obesity. The other tests do not provide the comprehensive assessment of sleep patterns necessary to diagnose sleep apnea.
Which of the following best explains the role of the gut hormone ghrelin in obesity?
Ghrelin increases appetite and food intake, potentially contributing to obesity.
Ghrelin suppresses appetite and promotes satiety.
Ghrelin regulates insulin secretion exclusively in the pancreas.
Ghrelin is unrelated to energy homeostasis.
Ghrelin is commonly known as the 'hunger hormone' because it stimulates appetite and promotes food intake, factors that can contribute to obesity. The other statements either contradict its established function or misrepresent its role in energy balance.
In long-term postoperative follow-up for bariatric patients, which nutritional deficiency is most commonly observed?
Vitamin B12 deficiency
Vitamin C deficiency
Vitamin A deficiency
Vitamin K deficiency
Vitamin B12 deficiency is commonly seen after bariatric surgery due to altered gastric anatomy and reduced intrinsic factor production, impairing its absorption. Other nutritional deficiencies may occur but are not as frequently encountered in the postoperative period.
Which of the following factors most significantly influences patient eligibility for bariatric surgery?
A BMI ≥40 or ≥35 with obesity-related comorbidities
Patient age over 65 years only
Previous weight loss diet attempts only
History of cosmetic procedures
Eligibility for bariatric surgery is primarily determined by BMI criteria, typically a BMI of 40 or a BMI of 35 accompanied by obesity-related comorbidities. The other options are not central factors in determining surgical candidacy.
