CERTIFIED BARIATRIC NURSE (CBN)
ORIGINAL PRACTICE EXAM [QUESTIONS 1–100]
AND ANSWERS UPDATED 2026/2027 | DETAILED
RATIONALES | STUDY PREPARATION
Introduction:
**This original Certified Bariatric Nurse (CBN) practice set is designed to help nurses prepare
for specialty certification in metabolic and bariatric nursing. The questions emphasize clinical
judgment, patient safety, evidence-informed care, interdisciplinary collaboration, and quality
improvement across the continuum of obesity and metabolic and bariatric surgery care. The
content follows the current publicly available CBN examination framework, which covers
preoperative clinical management, perioperative clinical management, post-hospital follow-up,
professional and community collaboration, and program quality. The practice questions are
intentionally scenario-based so that candidates must apply concepts rather than rely on
memorization. Topics include patient assessment, informed decision-making, nutritional and
behavioral considerations, postoperative complications, medication considerations, long-term
follow-up, psychosocial care, communication, and quality improvement. Candidates should use
these questions alongside the current CBN Candidate Handbook, examination content outline,
and authoritative clinical references. This material is independently written practice content and
is not reproduced from or predictive of secure CBN examination questions. It is intended to
strengthen reasoning and identify areas requiring further study rather than guarantee
examination success.**
Core Domains Covered:
1. Clinical Management: Preoperative — Pre-hospital: Assessment, education, risk
identification, treatment options, psychosocial considerations, informed decision-making, and
preparation for metabolic and bariatric surgery.
2. Clinical Management: Perioperative — Hospital: Immediate postoperative assessment,
surgical nursing care, complication recognition, pain management, mobility, respiratory care,
nutrition progression, and discharge preparation.
3. Clinical Management: Follow-up — Post-hospital: Long-term monitoring, nutritional
adequacy, supplementation, weight-management behaviors, medication considerations,
complications, psychosocial needs, and follow-up care.
4. Professional and Community Collaboration: Interdisciplinary communication, patient
advocacy, education, referral, community resources, professional responsibilities, and
coordination of care.
,5. Program Quality: Quality improvement, patient safety, outcomes measurement, risk
management, evidence-based practice, documentation, accreditation-related processes, and use
of data to improve bariatric services.
QUESTIONS 1–100
Question 1
A 42-year-old patient with severe obesity is being evaluated for metabolic and bariatric surgery.
Which assessment finding is most important for identifying an immediate factor that could affect
surgical readiness?
A) Preference for a particular postoperative diet
B) Uncontrolled medical or psychiatric condition requiring stabilization
C) Interest in attending a support group
D) Previous participation in a commercial weight-loss program
Rationale: The correct answer is B because uncontrolled conditions can increase perioperative
risk and may require stabilization before surgery. A, C, and D may be relevant to planning but
do not represent the same immediate safety concern.
Question 2
A patient states, “I thought surgery would guarantee that I never regain weight.” What is the
nurse's best response?
A) “Weight regain does not occur after bariatric surgery.”
B) “Surgery works independently of eating and activity behaviors.”
C) “Surgery is an important treatment tool, but long-term outcomes also depend on ongoing
behavioral and medical management.”
D) “You should avoid surgery if you are concerned about weight regain.”
Rationale: The correct answer is C because metabolic and bariatric surgery is part of a long-
term disease-management strategy. A and B provide false reassurance, while D unnecessarily
discourages an established treatment option.
Question 3
During preoperative assessment, a patient reports previous abdominal surgery. Which
information is most useful to obtain?
A) Favorite foods
B) Operative history and postoperative complications
C) Preferred exercise environment
D) Current clothing size
,Rationale: The correct answer is B because previous abdominal operations may influence
operative planning, adhesions, anatomy, and risk. The other information can be useful for
broader assessment but is less directly relevant to operative planning.
Question 4
A patient expresses uncertainty about whether to proceed with surgery. What is the nurse's
priority action?
A) Persuade the patient to proceed
B) Provide balanced education and support informed decision-making
C) Tell the patient that hesitation means surgery is contraindicated
D) Ask the family to make the decision
Rationale: The correct answer is B. The nurse supports informed decision-making by ensuring
the patient understands benefits, risks, alternatives, and expectations. A and D undermine
autonomy, while C is an unsupported conclusion.
Question 5
Which finding should prompt the bariatric nurse to explore psychosocial readiness more
thoroughly?
A) Patient asks detailed questions about postoperative nutrition
B) Patient demonstrates understanding of expected follow-up
C) Patient expects surgery to resolve all interpersonal and emotional problems
D) Patient has arranged transportation home
Rationale: The correct answer is C because unrealistic expectations can interfere with
adaptation and long-term outcomes. The other findings indicate preparation and engagement.
Question 6
A patient says, “I have tried many diets, so surgery is my only option.” Which response is best?
A) “Correct; surgery is always the final option.”
B) “Let's discuss the range of evidence-based treatment options and how surgery fits into your
overall treatment plan.”
C) “Dieting is ineffective for everyone with obesity.”
D) “You should decide based only on your current weight.”
Rationale: B supports shared decision-making and recognizes obesity as a chronic disease
requiring individualized treatment. A and C are overly absolute, while D ignores comorbidities
and other clinical factors.
Question 7
, Which preoperative teaching point is most important regarding postoperative medication
management?
A) Every medication will remain unchanged
B) Some medications may require formulation, dose, timing, or monitoring changes after surgery
C) Prescription medications are unnecessary after surgery
D) All medications should automatically be stopped
Rationale: B is correct because altered gastrointestinal anatomy and postoperative changes can
affect medication absorption and clinical response. A, C, and D are unsafe generalizations.
Question 8
A patient reports loud snoring, witnessed pauses in breathing during sleep, and daytime fatigue.
What should the nurse recognize?
A) These findings are unrelated to obesity
B) Possible obstructive sleep apnea requiring evaluation
C) Normal findings before surgery
D) Evidence of postoperative dumping syndrome
Rationale: B is correct. The described symptoms are characteristic of possible obstructive sleep
apnea, which has important perioperative implications. The other options do not explain the
presentation.
Question 9
Which approach best demonstrates culturally responsive preoperative education?
A) Use identical teaching for every patient
B) Ask about cultural beliefs, food practices, language needs, and health preferences
C) Avoid discussing cultural factors
D) Require the patient's family to interpret all education
Rationale: B promotes individualized and culturally responsive care. A ignores individual
differences, C can create barriers, and D may compromise accurate communication when
qualified interpretation is needed.
Question 10
A patient with obesity reports using nicotine products before planned surgery. What is the nurse's
priority?
A) Ignore the information because it does not affect surgery
B) Provide education about surgical risks associated with nicotine use and reinforce the
program's cessation requirements
