Question 1
A 42-year-old patient with a BMI of 46 kg/m² is admitted for evaluation
of severe obstructive sleep apnea and hypertension. During the nursing
assessment, which finding most strongly indicates increased risk for
obesity-related hypoventilation?
A. Resting heart rate of 92 beats/minute
B. Daytime somnolence with chronic hypercapnia
C. Mild bilateral ankle edema after prolonged standing
D. Occasional snoring during sleep
Answer: B. Daytime somnolence with chronic hypercapnia
Rationale: Obesity hypoventilation syndrome is characterized by
obesity accompanied by awake alveolar hypoventilation, typically
manifested by elevated arterial carbon dioxide levels after other causes
of hypoventilation have been excluded. Excessive daytime sleepiness,
morning headaches, hypoxemia, and hypercapnia are important
clinical clues. Snoring alone is more characteristic of obstructive sleep
apnea and does not establish hypoventilation.
Question 2
1
,A bariatric nurse is assessing a patient who is being considered for
metabolic and bariatric surgery. The patient states, "I know surgery will
make me lose weight, so I won't need to change anything about what I
eat." What is the nurse's best response?
A. "That is correct because surgery permanently prevents weight gain."
B. "You will need to avoid all carbohydrates permanently."
C. "Surgery changes your gastrointestinal anatomy and physiology, but
long-term success requires sustained nutritional, behavioral, and lifestyle
changes."
D. "You should postpone surgery until you can independently maintain a
normal BMI."
Answer: C. "Surgery changes your gastrointestinal anatomy and
physiology, but long-term success requires sustained nutritional,
behavioral, and lifestyle changes."
Rationale: Bariatric surgery is a powerful treatment for obesity, but it
is not a substitute for long-term behavioral and nutritional
management. Patients must understand postoperative dietary
progression, physical activity, vitamin and mineral supplementation,
follow-up, and behavioral adaptation. Surgery does not guarantee
permanent weight loss without ongoing participation in care.
Question 3
A patient is two days postoperative following Roux-en-Y gastric bypass.
The patient reports increasing abdominal pain, tachycardia, and left
shoulder discomfort. The nurse notes a temperature of 38.3°C (100.9°F).
Which complication should the nurse suspect first?
A. Dumping syndrome
B. Anastomotic leak
2
,C. Lactose intolerance
D. Iron deficiency
Answer: B. Anastomotic leak
Rationale: Tachycardia, fever, abdominal pain, referred shoulder
pain, and clinical deterioration during the early postoperative period
are concerning for an anastomotic or staple-line leak. A leak can
rapidly progress to peritonitis, sepsis, and shock and requires
immediate evaluation. Dumping syndrome generally occurs after
eating and is not typically characterized by persistent postoperative
tachycardia and fever.
Question 4
A patient who underwent Roux-en-Y gastric bypass reports dizziness,
diaphoresis, palpitations, abdominal cramping, and diarrhea
approximately 20 minutes after eating a meal high in simple
carbohydrates. Which condition is most likely?
A. Early dumping syndrome
B. Late dumping syndrome
C. Bowel obstruction
D. Cholecystitis
Answer: A. Early dumping syndrome
Rationale: Early dumping syndrome usually occurs within minutes
after eating and results from rapid delivery of hyperosmolar gastric
contents into the small intestine. Symptoms can include abdominal
cramping, diarrhea, nausea, vasomotor symptoms, tachycardia,
diaphoresis, and weakness. Late dumping occurs later, often one to
three hours after eating, and is primarily related to postprandial
hypoglycemia.
3
, Question 5
A patient develops confusion, tremors, diaphoresis, and weakness
approximately two hours after consuming a sweetened beverage
following gastric bypass surgery. Which mechanism best explains the
symptoms?
A. Excessive gastric acid production
B. Reactive hypoglycemia caused by rapid glucose absorption and
insulin release
C. Acute vitamin B12 toxicity
D. Delayed intestinal obstruction
Answer: B. Reactive hypoglycemia caused by rapid glucose
absorption and insulin release
Rationale: Late dumping syndrome is associated with rapid
carbohydrate absorption, a rapid rise in blood glucose, and an
exaggerated insulin response that can subsequently cause
hypoglycemia. Symptoms include weakness, tremor, sweating,
palpitations, confusion, and sometimes syncope. Dietary management
generally emphasizes smaller meals and avoidance of concentrated
simple sugars.
Question 6
A patient with a BMI of 52 kg/m² is being prepared for surgery. Which
nursing intervention is particularly important for reducing postoperative
pulmonary complications?
A. Encourage prolonged bed rest before surgery
B. Avoid incentive spirometry because obesity restricts lung expansion
C. Encourage preoperative respiratory exercises and postoperative
pulmonary hygiene
D. Restrict ambulation until all postoperative pain has resolved
