& NCLEX-Style Questions
Question 1: A nurse is performing an abdominal assessment on a
client. Which of the following sequences should the nurse use?
A. Inspection, Palpation, Percussion, Auscultation
B. Inspection, Auscultation, Percussion, Palpation
C. Auscultation, Inspection, Palpation, Percussion
D. Palpation, Percussion, Auscultation, Inspection
CORRECT ANSWER: B. Inspection, Auscultation, Percussion,
Palpation
Rationale: For abdominal assessment, auscultation must be performed
before percussion and palpation because physical manipulation can
stimulate peristalsis and alter bowel sound frequency, leading to inaccurate
findings.
Question 2: A client with gastroesophageal reflux disease (GERD)
reports that symptoms worsen when bending over. The nurse
should identify that this occurs due to which mechanism?
A. Increased gastric acid production during physical activity
B. Decreased lower esophageal sphincter pressure from position change
C. Compression of the stomach increasing intra-abdominal pressure
D. Delayed gastric emptying caused by positional changes
CORRECT ANSWER: C. Compression of the stomach increasing
intra-abdominal pressure
Rationale: Bending over increases intra-abdominal pressure, which
compresses the stomach and forces gastric contents upward past a
incompetent lower esophageal sphincter, exacerbating reflux symptoms.
,Question 3: A nurse is providing discharge teaching to a client with
GERD. Which statement by the client indicates understanding of
dietary modifications?
A. "I will eat three large meals per day to reduce acid exposure."
B. "I will drink peppermint tea after meals to aid digestion."
C. "I will avoid eating within three hours of bedtime."
D. "I will lie down for 30 minutes after eating to rest my stomach."
CORRECT ANSWER: C. "I will avoid eating within three hours of
bedtime."
Rationale: Eating close to bedtime increases gastric acid production while
lying flat, worsening reflux. Clients should remain upright for at least 2-3
hours after meals and avoid late evening meals.
Question 4: A client with peptic ulcer disease (PUD) asks the nurse
which diagnostic test is most accurate for identifying Helicobacter
pylori infection. The nurse should identify which test?
A. Abdominal X-ray
B. Barium swallow
C. Urea breath test
D. Serum amylase
CORRECT ANSWER: C. Urea breath test
Rationale: The urea breath test is a highly accurate, non-invasive method
for detecting active H. pylori infection by measuring exhaled carbon
dioxide produced when the bacterium metabolizes ingested urea.
Question 5: A client with peptic ulcer disease is prescribed triple
therapy. Which combination of medications should the nurse
expect?
A. Omeprazole, sucralfate, and misoprostol
B. Amoxicillin, clarithromycin, and omeprazole
C. Metronidazole, cimetidine, and aluminum hydroxide
D. Pantoprazole, loperamide, and ondansetron
,CORRECT ANSWER: B. Amoxicillin, clarithromycin, and
omeprazole
Rationale: Triple therapy for H. pylori eradication typically consists of two
antibiotics (such as amoxicillin and clarithromycin) plus a proton pump
inhibitor (omeprazole) to promote ulcer healing and reduce recurrence.
Question 6: A nurse is assessing a client with a suspected
perforated peptic ulcer. Which finding should the nurse expect?
A. Hyperactive bowel sounds in all quadrants
B. Rigid, board-like abdomen
C. Pain relieved by food intake
D. Increased flatulence and belching
CORRECT ANSWER: B. Rigid, board-like abdomen
Rationale: Perforation of a peptic ulcer leads to peritonitis, which causes
involuntary guarding and a rigid, board-like abdomen due to peritoneal
irritation. This is a surgical emergency.
Question 7: A client with cirrhosis develops hepatic
encephalopathy. Which medication should the nurse anticipate
administering to reduce ammonia levels?
A. Furosemide
B. Propranolol
C. Lactulose
D. Spironolactone
CORRECT ANSWER: C. Lactulose
Rationale: Lactulose is a synthetic disaccharide that traps ammonia in the
colon and promotes its excretion through the stool by creating an acidic
environment that converts ammonia to ammonium.
Question 8: A client is recovering from a liver biopsy. In which
position should the nurse place the client immediately after the
procedure?
, A. High-Fowler's position
B. Left-side lying position
C. Right-side lying position
D. Supine with legs elevated
CORRECT ANSWER: C. Right-side lying position
Rationale: Placing the client on the right side applies direct pressure over
the biopsy site in the right upper quadrant, compressing the liver capsule
against the abdominal wall to prevent hemorrhage.
Question 9: A nurse is monitoring a client with acute pancreatitis.
Which laboratory finding is most specific to this condition?
A. Elevated serum albumin
B. Decreased white blood cell count
C. Elevated serum lipase
D. Decreased blood glucose
CORRECT ANSWER: C. Elevated serum lipase
Rationale: Serum lipase is more specific to pancreatic injury than amylase
and remains elevated longer (up to 14 days), making it a reliable diagnostic
marker for acute pancreatitis.
Question 10: A client with acute pancreatitis should be maintained
on which initial dietary status?
A. High-fat, high-protein diet
B. NPO status with IV hydration
C. Clear liquid diet with caffeine-free beverages
D. Small frequent meals every 2 hours
CORRECT ANSWER: B. NPO status with IV hydration
Rationale: NPO status rests the pancreas by reducing stimulation of
pancreatic enzyme secretion, which decreases autodigestion and
inflammation. IV hydration maintains hemodynamic stability.
