Domain: Preoperative Management
1. A 45-year-old patient with a BMI of 51 kg/m² asks about the risks of
bariatric surgery. What is the most accurate response regarding 30-day
mortality?
A) "There is virtually no risk of death from this procedure."
B) "The 30-day mortality risk is approximately 0.1-0.5% for most
procedures."
C) "The mortality risk is over 5%, so it's a very high-risk surgery."
D) "Mortality is only a concern for patients over 60 years old."
Correct Answer: B
Rationale: The 30-day mortality risk for bariatric surgery is generally low,
estimated between 0.1% and 0.5%, although it can be slightly higher for
certain high-risk patients. It is important to be honest and transparent with
the patient while providing accurate context .
,2. A patient with a history of gout is being evaluated for surgery.
Which statement is most accurate regarding the effect of surgery on
their condition?
A) Gout is a contraindication to bariatric surgery.
B) Gout will be completely cured by the surgery.
C) Gout may temporarily worsen postoperatively due to rapid weight
loss.
D) Gout is not affected by bariatric surgery.
Correct Answer: C
Rationale: During the rapid weight loss phase, uric acid levels in the blood
can increase, potentially triggering a gout flare. Patients should be
educated about this possibility and may require prophylactic treatment .
Domain: Perioperative (Hospital) Management
3. A patient is 4 hours post-operative from a Roux-en-Y gastric bypass.
The nurse should monitor for which early sign of a potential
anastomotic leak?
A) A fever of 100.4°F (38°C).
B) Nausea without vomiting.
C) Tachycardia (heart rate 115 bpm).
D) Mild abdominal discomfort.
Correct Answer: C
Rationale: Tachycardia is often one of the most reliable and earliest signs
of an anastomotic leak or internal hemorrhage, sometimes appearing
before fever or overt abdominal pain .
4. The nurse is preparing to care for a patient post-bariatric surgery.
Which intervention is most critical for preventing venous
thromboembolism (VTE)?
A) Strict bed rest for the first 24 hours.
B) Administration of a sequential compression device (SCD) only.
, C) A combination of early ambulation, SCDs, and pharmacologic
prophylaxis.
D) Ensuring the patient is well-hydrated with a full liquid diet.
Correct Answer: C
Rationale: Bariatric patients are at high risk for VTE. A multimodal
approach is the standard of care, combining early mobilization, mechanical
prophylaxis (SCDs), and anticoagulant medications (e.g., heparin or
enoxaparin) .
Domain: Follow-up (Post-hospital) Management
5. A patient presents to the clinic 6 months post-surgery and reports
symptoms of severe abdominal cramping, diaphoresis, and tachycardia
shortly after eating a meal. What is the most likely diagnosis?
A) Anastomotic stricture.
B) Gastric outlet obstruction.
C) Dumping syndrome.
D) Marginal ulcer.
Correct Answer: C
Rationale: This is a classic presentation of early dumping syndrome, which
occurs when hyperosmolar food boluses rapidly enter the small intestine,
causing a fluid shift and sympathetic nervous system activation .
6. A patient who underwent Roux-en-Y gastric bypass is in the
emergency department with signs of a bowel obstruction. Which
historical factor is the most important for the emergency department
nurse to communicate to the provider?
A) The patient's pre-operative BMI.
B) The patient's current dietary intake.
C) The patient's altered gastrointestinal anatomy.
D) The patient's history of psychiatric medication use.
, Correct Answer: C
Rationale: It is critical that healthcare providers unfamiliar with bariatric
patients recognize their altered anatomy. An internal hernia is a life-
threatening complication of RYGB that can cause a bowel obstruction .
Domain: Preoperative Management (continued)
7. A patient with a BMI of 48 kg/m² and obstructive sleep apnea (OSA)
is scheduled for bariatric surgery. Which preoperative intervention is
most critical?
A) Prescribing a high-protein liquid diet for 2 weeks.
B) Referring the patient for a sleep study and CPAP titration.
C) Starting the patient on an anticoagulant.
D) Ordering a cardiac stress test.
Correct Answer: B
Rationale: Undiagnosed or poorly managed OSA significantly increases
perioperative risks, including hypoxemia and cardiac arrhythmias.
Optimizing CPAP therapy preoperatively is essential for patient safety.
8. Which laboratory finding would be a relative contraindication to
proceeding with bariatric surgery?
A) Hemoglobin A1c of 7.2%
B) Vitamin D level of 15 ng/mL
C) Hemoglobin of 9.5 g/dL
D) Potassium of 4.0 mEq/L
Correct Answer: C
Rationale: Significant anemia (Hb <10 g/dL) may indicate underlying
bleeding, nutritional deficiency, or bone marrow suppression that should be
evaluated and corrected before surgery to reduce operative risk.
