PRACTICE EXAM 100 HIGHLY
CHALLENGING QUESTIONS WITH DEPTH
RATIONALES.
Question 1
A nurse is performing an abdominal assessment on a client
admitted with suspected acute small bowel obstruction. Which of
the following sequences must the nurse utilize to avoid altering
the baseline physical findings?
A. Inspection, palpation, percussion, auscultation
B. Inspection, auscultation, percussion, palpation
C. Auscultation, inspection, percussion, palpation
D. Palpation, percussion, auscultation, inspection
CORRECT ANSWER: B
RATiONAlE: To obtain accurate abdominal assessment data,
the nurse must perform inspection first, followed immediately by
auscultation. Palpation and percussion stimulate bowel motility
and can artificially alter the frequency and character of bowel
sounds if performed prior to auscultation.
Question 2
A nurse is caring for a client who is 1 hour postoperative following
an esophagogastroduodenoscopy (EGD). Which of the following
assessment findings requires immediate notification of the
provider?
,A. Sore throat and mild hoarseness when speaking
B. Absence of the gag reflex upon stimulation
C. Sudden onset of sharp, radiating substernal pain
D. Diffuse abdominal bloating and mild belching
CORRECT ANSWER: C
RATiONAlE: Sharp, sudden, or radiating substernal,
epigastric, or back pain can indicate systemic perforation of the
esophagus or stomach, which is a life-threatening emergency. A
sore throat and bloating are expected side effects. The gag reflex
is expected to be absent for 1 to 2 hours due to topical local
anesthetics used during the procedure.
Question 3
A nurse is providing discharge teaching to a client who underwent
a subtotal gastrectomy for gastric cancer. To prevent the onset of
dumping syndrome, which dietary instruction should the nurse
include?
A. Drink 8 ounces of water concurrently with each meal.
B. Consume high-carbohydrate, simple sugar foods for rapid
energy.
C. Remain in an upright, sitting position for 60 minutes after
eating.
D. Eat small, frequent meals that are low in carbohydrates and
high in protein.
CORRECT ANSWER: D
RATiONAlE: Dumping syndrome is prevented by consuming
small, frequent meals high in protein and fat, and low in simple
carbohydrates. Clients should avoid fluids with meals (drinking
,them 30–60 minutes before or after instead) and should lie down
or recline for 30 minutes after eating to slow gastric emptying.
Question 4
A nurse is reviewing the laboratory results of a client admitted 24
hours ago with severe acute pancreatitis. Which of the following
findings poses the highest risk for neuromuscular instability and
requires immediate intervention?
A. Serum amylase 320 U/L
B. Serum lipase 410 U/L
C. Total serum calcium 7.2 mg/dL
D. Blood urea nitrogen (BUN) 28 mg/dL
CORRECT ANSWER: C
RATiONAlE: Hypocalcemia (calcium < 8.5 mg/dL) is a
critical complication of acute pancreatitis caused by fat necrosis
and saponification. It can lead to tetany, prolonged QT intervals,
seizures, and laryngospasm. Amylase and lipase elevations
confirm the diagnosis but do not cause immediate
neuromuscular instability.
Question 5
A nurse is assessing a client with a history of a peptic ulcer who
presents to the emergency department reporting sudden,
excruciating abdominal pain. The nurse notes a rigid, board-like
abdomen with severe rebound tenderness. Which complication
should the nurse suspect?
A. Gastrointestinal hemorrhage
B. Gastric outlet obstruction
, C. Peritonitis secondary to perforation
D. Acute mechanical bowel obstruction
CORRECT ANSWER: C
RATiONAlE: A sudden onset of severe abdominal pain
accompanied by a rigid, board-like abdomen, guarding, and
rebound tenderness are hallmark signs of peritonitis, typically
occurring after a peptic ulcer perforates into the peritoneal
cavity.
Question 6
A nurse is reviewing the medical records of several clients on a
medical-surgical unit. Which finding is uniquely characteristic of
Crohn's disease rather than ulcerative colitis?
A. Continuous inflammation localized strictly to the mucosa of the
rectum and colon
B. Transmural inflammation with a "cobblestone" appearance and
skip lesions
C. Profuse, bloody diarrhea containing mucus occurring 15–20
times per day
D. High incidence of cure following a total proctocolectomy with
ileostomy
CORRECT ANSWER: B
RATiONAlE: Crohn's disease features transmural (all layers
of the bowel wall) inflammation, skip lesions (patchy areas of
disease separated by normal tissue), and a cobblestone mucosal
appearance. Ulcerative colitis is continuous, affects only the
mucosa/submucosa, is confined to the colon/rectum, and
features prominent bloody diarrhea.
