INTRODUCTION:
This Certified Bariatric Nurse (CBN) intensive practice set is designed to strengthen clinical
reasoning across the major areas of bariatric nursing care. The questions emphasize
assessment, patient education, perioperative management, nutrition, postoperative
complications, psychosocial considerations, long-term follow-up, and interdisciplinary care.
Rather than relying on memorization alone, the scenarios require the learner to identify
priorities, interpret clinical findings, recognize complications, apply evidence-informed
nursing principles, and select the safest intervention. Bariatric nursing requires
understanding how surgical procedures, altered gastrointestinal anatomy, nutrition,
medication management, behavior change, and chronic disease interact throughout the
patient journey. This review therefore emphasizes both immediate postoperative safety and
long-term patient-centered management. Each question includes a detailed rationale
explaining the reasoning behind the correct response and why the alternatives are less
appropriate. The material is intended to complement current institutional protocols,
professional guidance, and the candidate’s formal CBN preparation resources.
Core Domains Covered:
1. Bariatric Surgery and Patient Selection — Understanding common metabolic and bariatric
procedures, indications, contraindications, surgical anatomy, and expected outcomes.
2. Preoperative Assessment and Preparation — Evaluating medical, nutritional, behavioral,
psychosocial, and educational readiness before surgery.
3. Perioperative and Postoperative Nursing Care — Recognizing priorities involving airway,
circulation, mobility, pain, hydration, wound care, and early complication detection.
4. Nutrition and Micronutrient Management — Applying principles of staged dietary
progression, protein intake, hydration, vitamin supplementation, and laboratory monitoring.
5. Postoperative Complications — Identifying and responding appropriately to bleeding, leaks,
obstruction, dehydration, thromboembolic events, nutritional deficiencies, and other
complications.
6. Psychosocial and Behavioral Health — Supporting behavioral change, coping, body-image
adjustment, adherence, eating behaviors, and appropriate mental-health referral.
,7. Long-Term Follow-Up and Chronic Disease Management — Monitoring weight trajectory,
comorbidities, nutritional status, medication effects, and lifelong follow-up needs.
Questions 1–100
Question 1: A patient is preparing for Roux-en-Y gastric bypass and asks why the procedure can
improve type 2 diabetes before substantial weight loss occurs. Which explanation is most
appropriate?
A) The procedure permanently eliminates pancreatic beta cells.
B) Changes in gut hormones and nutrient signaling can improve glucose regulation rapidly
after surgery.
C) The procedure prevents all dietary carbohydrate absorption.
D) Improved glycemic control occurs only after complete resolution of obesity.
Rationale: The correct answer is B because metabolic surgery can produce significant changes
in incretin signaling, insulin sensitivity, hepatic glucose metabolism, and other metabolic
pathways soon after surgery. A is incorrect because pancreatic beta cells are not intentionally
eliminated. C is incorrect because carbohydrate absorption is not completely prevented. D is
incorrect because improvements in glycemic control may occur before major weight loss.**
Question 2: During the preoperative assessment, a patient reports frequent episodes of eating
unusually large amounts of food accompanied by a sense of loss of control. What is the nurse's
priority?
A) Tell the patient that surgery will automatically eliminate the behavior.
B) Recommend skipping meals before surgery.
C) Communicate the finding to the bariatric team for further behavioral assessment and
intervention.
D) Cancel the procedure immediately without further evaluation.
Rationale: The correct answer is C because problematic eating behaviors should be assessed
and addressed as part of comprehensive bariatric care. A is incorrect because surgery does not
automatically resolve maladaptive eating behaviors. B may worsen disordered eating patterns.
D is inappropriate because the finding requires assessment and treatment planning rather than
an automatic cancellation.**
Question 3: A patient is one day after laparoscopic bariatric surgery and develops persistent
tachycardia, increasing abdominal pain, and a temperature elevation. Which complication should
the nurse consider most urgently?
A) Expected postoperative discomfort
B) Mild constipation
C) Anastomotic or staple-line leak
D) Long-term vitamin deficiency
,Rationale: The correct answer is C because persistent tachycardia accompanied by worsening
abdominal symptoms and fever can be an early warning pattern for a postoperative leak. A and
B do not adequately explain the concerning combination of findings. D develops over a longer
period and does not explain acute postoperative deterioration.**
Question 4: A patient after gastric bypass asks why lifelong vitamin and mineral
supplementation is necessary. Which response is best?
A) Supplements are necessary only during the first week.
B) Supplements replace the need for protein-containing foods.
C) Altered intake and gastrointestinal anatomy can increase the risk of long-term
micronutrient deficiencies.
D) Supplements prevent all possible postoperative complications.
Rationale: The correct answer is C because reduced intake, altered digestion, and altered
absorption can contribute to deficiencies involving nutrients such as iron, vitamin B12, folate,
calcium, and vitamin D. A is incorrect because supplementation is generally a long-term
component of bariatric care. B is incorrect because supplements do not replace adequate dietary
protein. D is too broad because supplementation cannot prevent every complication.**
Question 5: A patient immediately after bariatric surgery is prescribed early ambulation. What is
the primary rationale?
A) To increase appetite
B) To accelerate gastric emptying
C) To reduce postoperative complications such as venous thromboembolism and
pulmonary complications.
D) To increase caloric intake
Rationale: The correct answer is C because early mobility promotes circulation, reduces venous
stasis, supports pulmonary function, and contributes to recovery. A, B, and D are not the
principal reasons for early ambulation.**
Question 6: A patient who underwent sleeve gastrectomy reports persistent vomiting and
inability to maintain adequate fluid intake. Which assessment finding is most concerning?
A) Mild transient nausea after eating
B) Temporary reduced appetite
C) Decreased urine output with dizziness and orthostatic symptoms
D) Preference for small meals
Rationale: The correct answer is C because oliguria, dizziness, and orthostatic symptoms
suggest clinically significant dehydration. A and B can occur during recovery without
necessarily indicating a serious complication. D is expected after restrictive surgery.**
, Question 7: Which patient statement demonstrates correct understanding of postoperative eating
behavior?
A) “I should eat as quickly as possible before I feel full.”
B) “Large meals are preferable because I have fewer opportunities to eat.”
C) “I should eat slowly, chew thoroughly, and stop when I experience comfortable satiety.”
D) “Drinking large amounts during meals will help food pass through.”
Rationale: The correct answer is C because slow eating, thorough chewing, and attention to
satiety help reduce discomfort and support postoperative dietary adaptation. A and B increase
the risk of overeating and intolerance. D is incorrect because many bariatric programs advise
separating fluids from meals according to the program's protocol.**
Question 8: A patient six months after gastric bypass reports fatigue, pallor, and reduced
exercise tolerance. Which deficiency should the nurse suspect first?
A) Sodium excess
B) Iron deficiency
C) Vitamin C excess
D) Excess calcium
Rationale: The correct answer is B because iron deficiency can occur after gastric bypass and
may cause anemia, fatigue, pallor, and reduced exercise tolerance. The other choices do not best
explain the clinical presentation. Laboratory assessment is required to confirm the deficiency.**
Question 9: Which assessment is most important when evaluating a bariatric patient for
postoperative pulmonary complications?
A) Hair texture
B) Food preferences
C) Respiratory rate, oxygen saturation, breath sounds, and respiratory effort
D) Long-term weight history only
Rationale: The correct answer is C because respiratory assessment helps identify
hypoventilation, atelectasis, pneumonia, or other acute complications. A, B, and D may have
relevance in broader care but are not the priority for acute respiratory assessment.**
Question 10: A patient asks why the bariatric team emphasizes adequate protein intake after
surgery. Which response is best?
A) Protein is required only to prevent hunger.
B) Protein completely prevents weight regain.
C) Protein supports preservation of lean tissue and helps meet nutritional requirements
during rapid weight loss.
D) Protein eliminates the need for vitamin supplementation.
