A nurse is reviewing the pathophysiology of gastric mucosal protection. Exposure to
which substance is known to protect the mucosal barrier of the stomach?
a. Helicobacter pylori
b. Aspirin
c. Prostaglandins
d. Regurgitated bile
✔️ Correct Answer: C
Rationale:
Prostaglandins and enterogastrones, including gastric inhibitory peptide, somatostatin,
and secretin, play a protective role by inhibiting gastric acid secretion and maintaining
mucosal integrity. Option A is incorrect because H. pylori is a pathogenic organism that
contributes to mucosal damage and ulcer formation. Option B is incorrect because aspirin
is a known mucosal irritant that can disrupt the gastric barrier. Option D is incorrect
because regurgitated bile is harmful to the gastric mucosa and can cause chemical
gastritis.

A nurse is monitoring a client with uncontrolled diabetes mellitus. At what plasma
glucose level does the renal threshold for glucose typically become exceeded?
a. 126 mg/dL
b. 150 mg/dL
c. 180 mg/dL
d. 200 mg/dL
✔️ Correct Answer: C
Rationale:
When plasma glucose reaches approximately 180 mg/dL, the renal threshold for glucose
reabsorption is exceeded, resulting in glucosuria. This is commonly observed in
individuals with uncontrolled diabetes mellitus. Option A is incorrect because 126 mg/dL
is the diagnostic threshold for diabetes mellitus but does not represent the renal
threshold. Option B is incorrect as 150 mg/dL is below the typical renal threshold. Option
D is incorrect because 200 mg/dL exceeds the threshold but is not the standard value
used to define threshold achievement.
A nurse is educating a client about the pathophysiology of gastroesophageal reflux
disease. Which mechanism is identified as the primary cause of this condition?
a. Excessive production of hydrochloric acid
b. Zone of low pressure of the lower esophageal sphincter
c. Presence of Helicobacter pylori in the esophagus
d. Reverse muscular peristalsis of the esophagus
✔️ Correct Answer: B
Rationale:
Gastroesophageal reflux disease (GERD) primarily results from a zone of low pressure in
the lower esophageal sphincter (LES), which normally maintains a high-pressure zone to
prevent reflux. In individuals with GERD, this pressure is lower than normal due to
transient relaxation or weakness of the sphincter. Option A is incorrect because excessive

acid production may contribute to symptoms but is not the primary cause. Option C is
incorrect because H. pylori is associated with peptic ulcers, not GERD. Option D is
incorrect because reverse peristalsis is not the primary mechanism of GERD.
A nurse is assessing a client who has undergone a partial gastrectomy. The client presents
with increased pulse rate, hypotension, weakness, pallor, sweating, and dizziness. Which
mechanism is responsible for these clinical manifestations?
a. Anaphylactic reaction with chemical mediators causing vasodilation and shock
b. Postoperative hemorrhage with significant blood loss and compensatory tachycardia
c. Concentrated bolus moving from stomach to small intestine causing hyperglycemia
and hypovolemic shock
d. Rapid gastric emptying creating a high osmotic gradient in the small intestine, causing
fluid shift from blood vessels to intestinal lumen
✔️ Correct Answer: D
Rationale:
These manifestations are characteristic of dumping syndrome, which occurs in 5% to 10%
of individuals following partial gastrectomy or pyloroplasty. Rapid gastric emptying
creates a high osmotic gradient in the small intestine, causing a sudden shift of fluid from
the vascular compartment to the intestinal lumen. This results in decreased plasma
volume and vasomotor responses including tachycardia, hypotension, weakness, pallor,
sweating, and dizziness. Option A is incorrect because this is not an anaphylactic reaction.
Option B is incorrect because this is not primarily due to hemorrhage. Option C is
incorrect because the mechanism involves osmotic shifts rather than hyperglycemia.
A nurse is evaluating the pathophysiology of intestinal obstructions. By which mechanism
does intussusception cause an intestinal obstruction?
a. Telescoping of part of the intestine into another section, usually causing strangulation
of the blood supply
b. Twisting of the intestine on its mesenteric pedicle, causing occlusion of the blood

supply
c. Loss of peristaltic motor activity in the intestine, causing an adynamic ileus
d. Formation of fibrin and scar tissue attaching to the intestinal omentum, causing
obstruction
✔️ Correct Answer: A
Rationale:
Intussusception involves the telescoping of one segment of the intestine into an adjacent
segment, which typically results in strangulation of the blood supply to the affected
bowel. Option B describes volvulus, not intussusception. Option C describes adynamic
ileus. Option D describes adhesions, which can cause obstruction but are not the
mechanism of intussusception.
A nurse is caring for a client with a small intestinal obstruction. What is the most
immediate physiologic result of this condition?
a. Vomiting
b. Electrolyte imbalances
c. Dehydration
d. Distention
✔️ Correct Answer: D
Rationale:
Distention begins almost immediately following a small intestinal obstruction as gases
and fluids accumulate proximal to the obstruction. Within 24 hours, up to 8 liters of fluid
and electrolytes may enter the lumen from saliva, gastric juice, bile, pancreatic juice, and
intestinal secretions. Option A, vomiting, may occur but is not the most immediate result.
Option B and C develop over time as a consequence of fluid sequestration and vomiting.
A nurse is analyzing the acid-base balance of a client with an intestinal obstruction at the
pylorus. Which mechanism leads to metabolic alkalosis in this condition?
