Upper GI Bleeding and Peptic Ulcer Disease

Medical-Surgical · Gastrointestinal (GI)·Updated 2026-10-28

What it is

Peptic ulcer disease is erosion of the gastric or duodenal mucosa when acid and pepsin overcome the mucosal barrier; the two main causes are Helicobacter pylori infection and NSAID or aspirin use. Hemorrhage is the most common complication, followed by perforation and gastric outlet obstruction. Upper GI bleeding presents as hematemesis or melena and quickly leads to hypovolemic shock, so care centers on airway, volume replacement and stopping the source.

What the NCLEX focuses on

Gastric ulcer pain occurs 1 to 2 hours after meals and food worsens it; duodenal ulcer pain occurs 2 to 5 hours after meals or at night and food or antacids relieve it.
Upper GI bleeding: coffee-ground or bright red emesis, black tarry stool (melena), tachycardia, orthostatic hypotension, pallor and dizziness; BUN rises as blood is digested.
The first hemoglobin can be near normal; it falls only after fluid shifts or IV fluids dilute the blood.
Perforation: sudden severe epigastric pain spreading across the abdomen, rigid boardlike abdomen, absent bowel sounds, and a client lying still with knees drawn up; this is a surgical emergency.
Endoscopy within 24 hours diagnoses and treats the bleeding site; an IV proton pump inhibitor (PPI) reduces rebleeding.
H. pylori is diagnosed by urea breath test, stool antigen or biopsy, and treated with a PPI plus two or more antibiotics (often with bismuth) for 14 days; eradication is confirmed afterward.
Sucralfate is taken on an empty stomach 1 hour before meals and at bedtime, separated from other drugs; misoprostol is contraindicated in pregnancy.

Priority nursing actions

Assess airway, vital signs and level of consciousness; raise the head of the bed or turn the vomiting client to the side to prevent aspiration.
Insert two large-bore IV catheters and start isotonic crystalloid as prescribed.
Obtain CBC, type and crossmatch, coagulation studies and BUN; give packed red blood cells as prescribed.
Keep the client NPO, give the prescribed IV PPI and maintain the NG tube if one is prescribed.
Prepare the client for endoscopy.
Monitor vital signs, hourly urine output, hemoglobin and the amount and color of emesis and stool.

Numbers to know

Value	Normal or target	Why it matters
Transfusion threshold	Hemoglobin below 7 g/dL (70 g/L) in most clients	Restrictive transfusion improves outcomes
BUN	10 to 20 mg/dL (3.6 to 7.1 mmol/L)	Rises from digested blood in upper GI bleeding
Urine output	At least 0.5 mL/kg/h (about 30 mL/h)	Shows adequate perfusion during resuscitation
IV access	Two catheters, 18 gauge or larger	Allows rapid fluid and blood replacement
H. pylori treatment	14 days	Shorter courses fail more often
Test of cure	At least 4 weeks after therapy, PPI stopped 2 weeks before	Prevents a false-negative result

Common exam traps

Choosing iron supplements to explain black tarry stool with pale conjunctiva and tachycardia: wrong because these findings point to upper GI bleeding.
Choosing to keep a vomiting client supine: wrong because it raises aspiration risk.
Choosing iced saline lavage to stop bleeding: wrong because it is no longer recommended and causes hypothermia.
Choosing oral antacid for sudden severe pain with a rigid abdomen: wrong because perforation requires NPO status and emergency surgery.
Choosing to stop the antibiotics once ulcer pain resolves: wrong because incomplete therapy fails to eradicate H. pylori and breeds resistance.

What to teach

Take every H. pylori medication for the full 14 days and return for the test of cure.
Avoid NSAIDs and aspirin unless prescribed with a protective drug; use acetaminophen for pain; stop smoking and limit alcohol.
Take the PPI 30 to 60 minutes before breakfast.
Report black stools, vomiting blood or coffee-ground material, dizziness, or sudden severe abdominal pain right away.

Question 1 · QID 9AF00855

The nurse assesses clients with suspected gastrointestinal bleeding.

For each finding, identify the most likely bleeding pattern.

	Upper GI bleeding pattern	Lower GI bleeding pattern	Not enough to localize
A: Coffee-ground emesis
B: Black tarry stool with epigastric discomfort
C: Bright red blood coating stool with known hemorrhoids
D: Occult blood positive stool without symptoms
E: Bright red blood mixed throughout stool with left lower quadrant cramping

Question 2 · QID 6775C382

A client with peptic ulcer disease is prescribed a proton pump inhibitor and antibiotics for Helicobacter pylori. Which statement by the client indicates correct understanding?

Select the best answer.

A. I should take the medications exactly as prescribed even if symptoms improve.
B. I should test for H. pylori immediately after the last antibiotic dose.
C. If I miss one antibiotic dose, I should take two doses at the next scheduled time.
D. If my symptoms resolve, I do not need testing to confirm that H. pylori was eradicated.
