Certified Bariatric Nurse (CBN) Practice Exam 2
Questions and Answers with Rationales Latest
Versions Top Rated A+
1. Which statement best describes the role of a bariatric nurse?
A. Focus exclusively on postoperative wound care
B. Provide only dietary education
C. Provide comprehensive care addressing medical, nutritional,
behavioral, and psychosocial needs
D. Focus only on weight measurements
Answer: C
Rationale: Bariatric nursing encompasses comprehensive care across
the continuum, including assessment, patient education, perioperative
management, nutrition, medication management, complication
recognition, behavioral health, and long-term follow-up.
2. Which factor is considered a contributor to obesity?
A. Genetics
B. Environment
C. Medications
D. All of the above
Answer: D
Rationale: Obesity is multifactorial. Genetic predisposition,
environmental influences, medications, metabolic factors, sleep,
socioeconomic conditions, behavior, and other factors can contribute.
,3. Which statement about BMI is correct?
A. BMI directly measures body-fat percentage.
B. BMI is one screening measure used to classify weight status.
C. BMI independently diagnoses all obesity-related disease.
D. BMI determines the exact amount of visceral fat.
Answer: B
Rationale: BMI is useful for population-level and clinical screening but
does not directly measure body composition, fat distribution, or
individual metabolic health.
4. Which condition is commonly associated with severe obesity?
A. Obstructive sleep apnea
B. Type 2 diabetes
C. Hypertension
D. All of the above
Answer: D
Rationale: Severe obesity is associated with numerous comorbidities,
including obstructive sleep apnea, type 2 diabetes, hypertension,
dyslipidemia, cardiovascular disease, and musculoskeletal conditions.
5. Which statement about obesity-related inflammation is most
accurate?
A. Adipose tissue is completely metabolically inactive.
B. Excess adipose tissue can contribute to chronic low-grade
inflammation.
,C. Inflammation occurs only after bariatric surgery.
D. Obesity has no relationship with inflammatory pathways.
Answer: B
Rationale: Adipose tissue is metabolically active and can contribute to
inflammatory signaling. Chronic low-grade inflammation is associated
with several obesity-related metabolic complications.
6. Which bariatric procedure involves removal of a large portion of
the stomach?
A. Sleeve gastrectomy
B. Roux-en-Y gastric bypass
C. Adjustable gastric band
D. Biliopancreatic diversion only
Answer: A
Rationale: Sleeve gastrectomy removes a substantial portion of the
stomach, creating a narrow gastric sleeve and producing restrictive and
metabolic effects.
7. Roux-en-Y gastric bypass produces weight loss through:
A. Restriction only
B. A combination of restriction and altered gastrointestinal physiology
C. Removal of the pancreas
D. Elimination of intestinal absorption
Answer: B
Rationale: Roux-en-Y gastric bypass creates a small gastric pouch and
reroutes food through part of the small intestine, producing restriction
, along with important hormonal and metabolic effects and some degree
of altered nutrient absorption.
8. Which procedure is primarily restrictive?
A. Adjustable gastric band
B. Roux-en-Y gastric bypass
C. Biliopancreatic diversion with duodenal switch
D. Intestinal bypass alone
Answer: A
Rationale: Adjustable gastric banding primarily restricts food intake by
creating a small gastric pouch. It does not intentionally bypass the
intestine.
9. Which bariatric procedure generally carries substantial
nutritional monitoring requirements because of its malabsorptive
component?
A. Biliopancreatic diversion with duodenal switch
B. Adjustable gastric band
C. Behavioral therapy
D. Dietary counseling alone
Answer: A
Rationale: Procedures with greater intestinal bypass can substantially
affect nutrient absorption and therefore require careful, lifelong
nutritional monitoring and supplementation.
