Nursing study guide
Gastrointestinal nursing
Assess bleeding, obstruction, inflammation, nutrition, fluid loss, liver function, pancreas, and ostomy care.
Nursing filter
Assess the patient first, recognize time-sensitive change, prevent harm, and trend the response.
Connect systems
Symptoms, laboratory patterns, medications, nutrition, function, and psychosocial needs interact.
Safety boundary
Use current orders, facility policy, clinical supervision, and emergency pathways.
Assessment
Location, output, intake, and systemic effect organize the GI picture
Describe symptoms precisely and connect them to perfusion and hydration.
History
Onset, location, radiation, quality, meals, stool, emesis, weight, alcohol, medications, surgery, travel, infection, and prior disease.
Examine
Appearance, vital signs, hydration, abdomen, distention, bowel sounds in context, tenderness, guarding, output, skin, and mental status.
Escalate
Shock, rigid abdomen, severe pain, hematemesis, large melena/hematochezia, persistent vomiting, jaundice with confusion, or rapid deterioration.
GI bleeding
Treat blood loss and the cause
Bleeding can be occult, slow, or rapidly life-threatening.
Clues
Hematemesis, coffee-ground emesis, melena, hematochezia, dizziness, syncope, tachycardia, hypotension, pallor, fatigue, or falling hemoglobin.
Priorities
ABCs, hemodynamics, access, ordered labs/type and screen, NPO status, medication review, output measurement, preparation for endoscopy or intervention, and frequent reassessment.
Medication risk
Anticoagulants, antiplatelets, NSAIDs, steroids, alcohol, and liver disease affect risk and response; do not independently stop prescribed therapy without the urgent plan.
Bowel obstruction
Nothing moving can become ischemia or perforation
Mechanical obstruction and ileus require different evaluation, but both can cause fluid shifts and aspiration risk.
Pattern
Cramping or constant pain, distention, vomiting, reduced stool/flatus, altered bowel sounds, dehydration, and electrolyte changes.
Nursing priorities
NPO, aspiration precautions, IV fluid/electrolyte support, ordered decompression, accurate output, pain/nausea control, abdominal and perfusion trends, and surgical preparation.
Red flags
Continuous severe pain, peritoneal signs, fever, tachycardia, lactate rise, shock, or sudden worsening may signal strangulation, ischemia, or perforation.
Liver disease
Synthesis, detoxification, portal flow, and bile can all fail
Laboratory values and symptoms reflect different liver functions.
Assess
Jaundice, pruritus, bruising/bleeding, ascites, edema, nutrition, stool/urine color, infection, cognition, sleep, asterixis, and medication/substance exposure.
Complications
Variceal bleeding, encephalopathy, spontaneous bacterial peritonitis, hepatorenal dysfunction, severe coagulopathy, and acute liver failure are urgent.
Nursing priorities
Trend mental status, glucose, bleeding, fluid/weight/abdominal girth, renal function, electrolytes, infection, bowel plan, skin, fall/aspiration risk, and treatment response.
Pancreatic disease
Pancreatitis can drive severe pain, inflammation, and fluid loss
The cause, severity, and organ response determine care.
Acute pattern
Severe epigastric pain often radiating to the back, nausea/vomiting, tenderness, and elevated pancreatic enzymes in clinical context.
Priorities
ABCs, fluid/perfusion, pain and nausea control, glucose and electrolytes, oxygenation, nutrition plan, organ-failure surveillance, and cause-specific management.
Escalate
Hypotension, hypoxemia, oliguria, confusion, fever, increasing abdominal findings, bleeding, or organ dysfunction.
Ostomy care
A healthy stoma and intact skin support function
Type and location predict output and dehydration risk.
| Assess | Expected / goal | Report promptly |
|---|---|---|
| Stoma | Moist and pink/red with expected mild early edema | Dusky, pale, black, deeply retracted, severe bleeding, or abrupt change. |
| Output | Expected amount and consistency for the ostomy type | No output with cramping/nausea, very high watery output, or abrupt change. |
| Peristomal skin | Intact, dry, and protected by a correctly fitted barrier | Leak, denudement, infection, ulceration, or persistent pain. |
Nutrition + delegation
Protect intake without missing aspiration, obstruction, or refeeding risk
Nutrition plans are diagnosis- and patient-specific.
RN assessment
Swallow safety, GI function, access, tolerance, weight trend, electrolytes, glucose, hydration, stool/output, and cultural or access needs.
Delegate
Stable intake/output, weights, hygiene, ambulation, and specimen collection may be assigned with clear parameters.
Cross-reference
Review replacement and acid-base consequences in the related Nurse Arcade guide.
