Reasoning & Detailed Rationales
Question 1: A nurse is caring for a client who has been admitted
with a suspected upper gastrointestinal bleed. The client vomits
bright red blood and reports feeling lightheaded. Which of the
following assessment findings should the nurse identify as the
priority cue?
A. Heart rate of 118/min
B. Hemoglobin of 9.2 g/dL
C. Blood pressure of 88/56 mm Hg
D. Reports of nausea and abdominal cramping
CORRECT ANSWER: C. Blood pressure of 88/56 mm Hg
Rationale: In a client with active upper GI bleeding, hypotension indicates
significant volume loss and impending hypovolemic shock. While
tachycardia and falling hemoglobin are concerning, a systolic BP below 90
mm Hg represents a direct threat to organ perfusion and requires
immediate intervention to restore circulating volume.
Question 2: A nurse is teaching a client who has a new diagnosis of
celiac disease about dietary management. Which of the following
statements by the client indicates an understanding of the
teaching?
A. "I can eat rye bread as long as I toast it first."
B. "I need to avoid products containing wheat, barley, and rye."
C. "I should increase my intake of oat products to improve digestion."
D. "I can resume a regular diet once my symptoms resolve."
CORRECT ANSWER: B. "I need to avoid products containing wheat,
barley, and rye."
,Rationale: Celiac disease is an autoimmune disorder triggered by gluten,
which is found in wheat, barley, and rye. Strict lifelong avoidance of these
grains is essential to prevent inflammation and damage to the small
intestine.
Question 3: A nurse is assessing a client who reports burning
epigastric pain that worsens when lying down and improves with
sitting upright. The nurse should suspect which of the following
conditions?
A. Duodenal ulcer
B. Gastric ulcer
C. Gastroesophageal reflux disease (GERD)
D. Acute pancreatitis
CORRECT ANSWER: C. Gastroesophageal reflux disease (GERD)
Rationale: GERD is characterized by retrosternal burning that worsens with
recumbency and bending over because gravity no longer helps keep gastric
contents below the lower esophageal sphincter. Duodenal ulcers typically
cause pain relieved by food, while gastric ulcers cause pain worsened by
food.
Question 4: A nurse is caring for a client who has a nasogastric
(NG) tube connected to low intermittent suction. The client reports
nausea and the nurse notes decreased drainage. Which of the
following actions should the nurse take first?
A. Increase the suction setting
B. Irrigate the tube with normal saline
C. Administer a prescribed antiemetic
D. Reposition the client on the left side
CORRECT ANSWER: B. Irrigate the tube with normal saline
Rationale: When an NG tube is not draining adequately and the client
reports nausea, the nurse should first check patency by irrigating with
normal saline. This helps identify whether the tube is blocked or kinked,
which if unresolved would lead to gastric distention and vomiting.
Question 5: A nurse is reviewing laboratory results for a client who
has acute pancreatitis. Which of the following findings should the
nurse expect?
,A. Decreased serum amylase
B. Decreased serum lipase
C. Increased serum lipase
D. Increased serum albumin
CORRECT ANSWER: C. Increased serum lipase
Rationale: Acute pancreatitis causes inflammation and autodigestion of the
pancreas, leading to release of pancreatic enzymes into the bloodstream.
Lipase rises significantly and remains elevated longer than amylase, making
it a key diagnostic marker.
Question 6: A nurse is assessing a client who has peritonitis. Which
of the following findings should the nurse expect?
A. Hyperactive bowel sounds
B. Board-like abdomen
C. Bloody diarrhea
D. Periumbilical cyanosis
CORRECT ANSWER: B. Board-like abdomen
Rationale: Peritonitis causes severe inflammation of the peritoneal lining,
resulting in involuntary guarding and rigidity of the abdominal muscles,
described as a board-like abdomen. Bowel sounds are typically diminished
or absent due to paralytic ileus.
Question 7: A nurse is caring for a client who is 2 days
postoperative following a colostomy creation. The stoma appears
dark purple and dusky. Which of the following actions should the
nurse take first?
A. Document the finding as expected
B. Apply a warm compress to the stoma
C. Notify the provider immediately
D. Increase the frequency of stoma assessments
CORRECT ANSWER: C. Notify the provider immediately
Rationale: A healthy stoma should be pink to red and moist. A dusky, dark
purple, or black stoma indicates ischemia or necrosis due to compromised
blood supply. This requires immediate provider notification to prevent
further tissue damage.
, Question 8: A nurse is providing teaching to a client who has
cirrhosis and a new prescription for lactulose. Which of the
following statements by the client indicates an understanding of
the teaching?
A. "I should expect my stools to become firm and formed."
B. "I will need to monitor my blood glucose levels closely."
C. "I should report any confusion or increased drowsiness."
D. "This medication will help reduce my abdominal swelling."
CORRECT ANSWER: C. "I should report any confusion or increased
drowsiness."
Rationale: Lactulose is prescribed to reduce serum ammonia levels in
clients with hepatic encephalopathy. Expected effects include loose stools.
Increased confusion or drowsiness indicates worsening encephalopathy
and inadequate ammonia clearance, requiring provider notification.
Question 9: A nurse is assessing a client who reports severe right
lower quadrant pain with rebound tenderness at McBurney's point.
Which of the following conditions should the nurse suspect?
A. Cholecystitis
B. Diverticulitis
C. Appendicitis
D. Gastroenteritis
CORRECT ANSWER: C. Appendicitis
Rationale: Appendicitis classically presents with periumbilical pain that
migrates to the right lower quadrant, with rebound tenderness at
McBurney's point. This pattern of pain migration and localized tenderness
is highly specific for appendiceal inflammation.
Question 10: A nurse is caring for a client who has a small bowel
obstruction. Which of the following findings should the nurse
expect?
A. Absent bowel sounds in all quadrants
B. Hyperactive bowel sounds above the obstruction
C. Passage of flatus and formed stool
D. Bradycardia and hypertension
