Gastritis nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated September 2026
Short answer
Gastritis nursing care starts with identifying and removing the cause: NSAIDs, alcohol, or H. pylori infection. Assess for epigastric pain, nausea, and signs of bleeding, then support the stomach lining while the trigger is addressed rather than only masking symptoms with acid suppression.
The pathophysiology in one pass
Gastritis is inflammation of the gastric mucosa, and the exam wants you to know it breaks down into three named causes. NSAIDs inhibit prostaglandin synthesis, which strips away the mucosal layer that normally protects the stomach from its own acid. Alcohol directly irritates and erodes the mucosa. H. pylori burrows into the mucus layer and triggers a chronic inflammatory response that can persist for years if untreated.
Acute gastritis tends to follow a clear trigger, a course of ibuprofen or a heavy drinking episode, and resolves once the irritant is removed. Chronic gastritis, especially from H. pylori, develops more quietly and carries a real risk of progressing to peptic ulcer disease or, over decades, gastric cancer. Knowing which type you're dealing with changes both the urgency and the teaching.
Assessment findings that matter
Epigastric pain or burning, often described as gnawing, is the leading complaint, along with nausea, vomiting, and a feeling of fullness after small amounts of food. Ask specifically about NSAID use, including over-the-counter ibuprofen or aspirin the patient may not think to mention, and about alcohol intake in honest terms rather than a yes-or-no question.
Check for signs of bleeding at every assessment: coffee-ground emesis, melena, or a drop in haemoglobin on recent labs. Chronic gastritis can be silent for a long time, so a patient with vague dyspepsia and unexplained fatigue deserves a closer look rather than a quick reassurance. Palpate the epigastric region gently and note any guarding, which can suggest a more advanced process.
What the exam asks about this
NCLEX questions on gastritis usually test whether you can match the cause to the intervention: stopping NSAIDs for drug-induced gastritis, reducing alcohol for alcohol-induced gastritis, and starting triple or quadruple therapy for H. pylori. You'll also be asked to recognise upper GI bleeding as a complication and prioritise it over routine comfort measures.
Expect questions that present a patient on long-term NSAID therapy for arthritis and ask what to assess or teach, testing whether you connect chronic use to mucosal damage rather than treating the pain complaint in isolation. Questions may also test medication timing, such as taking a proton pump inhibitor before meals, or the correct sequence of H. pylori eradication therapy.
Nursing interventions in priority order
Remove or reduce the cause first. That means holding NSAIDs and discussing alternatives with the prescriber, counselling on alcohol reduction, and initiating H. pylori testing and treatment where indicated. This is the intervention that actually changes the disease trajectory, not an adjunct to it.
Alongside that, manage symptoms: administer acid-reducing medication as ordered, encourage small bland meals, and avoid caffeine, spicy food, and further alcohol while the mucosa heals. Monitor for bleeding with every shift assessment in acute cases. Educate on avoiding future NSAID use for minor aches once discharged, since recurrence is common if the original trigger returns unchanged.
Medications and monitoring
Proton pump inhibitors, such as omeprazole, reduce acid production and are typically given thirty to sixty minutes before the first meal of the day for best effect. H2 blockers like famotidine are an alternative or adjunct. Antacids can be used for quick symptom relief but should be spaced apart from other medications since they alter absorption.
H. pylori eradication uses combination therapy, commonly a proton pump inhibitor with two antibiotics, given for the full course even after symptoms improve, since stopping early risks resistance and treatment failure. Monitor haemoglobin and haematocrit in patients with suspected bleeding, and reinforce that NSAIDs, including combination cold and flu products, need to stay off the table during treatment.
When to escalate
Escalate immediately for haematemesis, melena, a sudden drop in blood pressure, or tachycardia, which point to active upper GI bleeding rather than simple inflammation. Severe, sudden epigastric pain with a rigid abdomen raises concern for perforation and needs urgent medical review, not another dose of antacid.
Also escalate when symptoms persist despite appropriate treatment, since this can indicate an incorrect diagnosis, treatment failure, or progression to peptic ulcer disease. A patient who can't tolerate oral intake, is dehydrated, or shows signs of anaemia from chronic occult bleeding needs prompt reassessment rather than being managed on the original plan alone.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our gastrointestinal practice questions are the closest set to what this page covers.
Common questions
What are the three main causes of gastritis nursing exams focus on?
NSAIDs, alcohol, and H. pylori infection. Each has a distinct mechanism of mucosal damage, and each calls for a different primary intervention: stopping the drug, reducing alcohol intake, or starting eradication therapy.
Why is removing the cause prioritised over giving antacids?
Antacids and acid suppressants relieve symptoms but don't stop ongoing mucosal damage if the trigger is still present. Removing NSAIDs, alcohol, or treating H. pylori addresses the actual process causing the inflammation.
What's the biggest complication to watch for in gastritis?
Upper GI bleeding. Watch for coffee-ground emesis, melena, a falling haemoglobin, or haemodynamic instability, and treat any of these as urgent rather than routine findings.
Can gastritis become chronic or lead to cancer?
Yes, particularly with untreated H. pylori infection, which can persist for years and is a recognised risk factor for peptic ulcer disease and gastric cancer. This is why eradication therapy is completed in full rather than stopped once symptoms ease.
How should proton pump inhibitors be timed for gastritis?
They're generally most effective when given thirty to sixty minutes before the first meal of the day, since they need to be active in the bloodstream when acid production ramps up with eating.
