7 Integrated Gastrointestinal Nursing Practice

Prioritize threats and reassess

Across gastrointestinal disorders, first identify immediate threats: airway compromise, shock, peritonitis, sepsis, aspiration, and rapidly worsening mental status. Stabilization and focused assessment often proceed at the same time. Reassess vital signs, perfusion, urine output, pain, abdominal findings, and laboratory trends, and escalate promptly if the patient deteriorates. Implement medications and procedures according to orders and local protocols.

Respond to hematemesis in cirrhosis

Treat large-volume Hematemesis in a patient with cirrhosis as a life-threatening upper gastrointestinal hemorrhage with possible variceal bleeding. Immediately call for emergency assistance, assess airway and breathing, provide oxygen as indicated, and initiate hemodynamic support under protocol.

Establish large-bore intravenous access, obtain ordered blood tests and a type-and-crossmatch, keep the patient NPO, and prepare for urgent endoscopic evaluation after resuscitation. Confusion and active bleeding increase aspiration risk. Worsening perfusion, reduced urine output, or ongoing bleeding requires immediate escalation; do not delay stabilization for diagnostic procedures.

Suspected variceal hemorrhage commonly prompts provider-ordered vasoactive medication and antibiotic prophylaxis, along with early endoscopy. An elevated INR in cirrhosis does not by itself mean plasma should automatically be given; treatment decisions belong to the clinical team.

Assess hematochezia with instability

Do not assume that Hematochezia with hemodynamic instability is from a lower gastrointestinal source. Brisk upper gastrointestinal bleeding can cause hematochezia, particularly in a patient with peptic ulcer or portal-hypertension risk.

Notify the provider, support circulation under protocol, obtain ordered laboratory tests and a crossmatch, and anticipate evaluation for an upper source as clinically indicated. Resuscitation and source assessment occur together. If bleeding remains hemodynamically significant, CT angiography may help localize active bleeding. Colonoscopy is generally not the first step before stabilization and appropriate preparation. Escalate immediately for sudden vital-sign changes or recurrent bleeding.

Recognize complications of bowel obstruction

Cramping abdominal pain, distention, vomiting, and no passage of stool or flatus can occur with Bowel obstruction. In a patient with Crohn’s disease, a change to constant severe pain, fever, tachycardia, and a rigid, tender abdomen raises concern for bowel ischemia, strangulation, or perforation rather than uncomplicated obstruction. Notify the provider or emergency response team immediately and prepare for urgent surgical evaluation.

Do not give food, drink, laxatives, or medications that could worsen the condition unless specifically directed. For a stable obstruction without signs of ischemia or peritonitis, initial management may include NPO status, nasogastric decompression, intravenous fluids, correction of electrolyte abnormalities, aspiration precautions, and serial reassessment. Crohn’s-related strictures may require specialist and surgical assessment.

Manage severe ulcerative colitis

Nine bloody stools in twenty-four hours, fever, tachycardia, and worsening abdominal distention during a hospitalized ulcerative colitis flare are concerning for acute severe disease and possible Toxic megacolon. Promptly report systemic signs and increasing distention. Assess vital signs, stool frequency and blood, abdominal tenderness, and serial laboratory trends as ordered.

The care team should evaluate for C. difficile and assess for colonic dilation. Avoid opioids and anticholinergic medications in suspected severe colitis or toxic megacolon because they can worsen colonic motility and dilation. Assess hospitalized patients with acute severe disease for venous thromboembolism prevention unless contraindicated. Perforation, toxic megacolon, severe refractory bleeding, or failure to respond to therapy requires urgent specialist and surgical involvement.

Reassess pancreatitis and fluid needs

With Acute pancreatitis, persistent vomiting and poor oral intake can accompany worsening perfusion. Falling urine output and rising BUN require attention, while new crackles and increasing oxygen needs during intravenous fluid administration also raise concern for fluid overload or evolving respiratory complications.

Reassess airway, breathing, oxygenation, lung sounds, vital signs, urine output, and fluid balance. Promptly report deterioration and anticipate a provider-directed reassessment of fluid therapy and level of care. Do not independently increase the fluid rate. Care uses intravenous crystalloid, often lactated Ringer’s, with frequent reassessment, especially early in the course. Antibiotics are not routine unless infection is suspected. When mild disease allows, oral feeding can resume early as tolerated rather than being unnecessarily delayed.

Evaluate confusion in decompensated cirrhosis

New confusion in a patient with cirrhosis may represent Hepatic encephalopathy, but do not attribute the change to liver disease alone. Search for precipitating causes, including infection and gastrointestinal bleeding. Fever and abdominal discomfort in a patient with ascites raise concern for infection, including spontaneous bacterial peritonitis. Promptly report fever, abdominal symptoms, and mental-status change; anticipate urgent provider evaluation, including diagnostic paracentesis when indicated.

Follow the prescribed Lactulose plan and document stool output and mental status. Lactulose is generally titrated to about two to three soft bowel movements daily. Excessive diarrhea can cause dehydration and electrolyte disturbances and may worsen the patient’s condition. Use fall and aspiration precautions as appropriate for the patient’s alertness.
