NCLEX-RN cheat sheet · Gastrointestinal
Lower GI, gallbladder and pancreas
IBD, diverticulitis, obstruction and NG tubes, appendicitis, ostomies, cholecystitis, pancreatitis
AI-checkedChecked by AI against current guidelines, with spot-checks by a registered nurse.
Lower GI problems range from colitis flares to a ruptured appendix, and many clients go home with a stoma. The gallbladder and pancreas both help digest fat, and both can flare with severe, sudden belly pain.

At a glance
Ulcerative colitis or Crohn's disease
| Ulcerative colitis | Crohn's disease | |
|---|---|---|
| Where | Colon only | Anywhere in the gut |
| Pattern | Spreads evenly up from the rectum | Jumps, with skip lesions |
| Stool | Bloody diarrhea with mucus | Diarrhea, usually not bloody |
| Pain | Often on the left | Right lower belly |
| Also | Removing the colon can cure the bowel symptoms | Weight loss, fistulas, abscesses and narrowing |
Both: Fever, a fast heart rate and dehydration; both flare and settle. Diarrhea drains potassium and magnesium; blood loss causes anemia. Drugs are individualized: mesalamine for selected colitis, not Crohn's, plus steroids, immune modifiers and biologics. Many raise the risk of infection.
IBD nursing care
- Track intake and output, stools, daily weight, potassium and magnesium.
- Fever, a rising pulse, more pain or a rising white count can mean perforation.
- Severe flare: IV fluids or parenteral nutrition may be needed.
- In a flare, avoid dairy, caffeine, alcohol, and high-fat and high-fiber foods.
- Teach: no anti-inflammatory pain relievers; regular colonoscopies for cancer risk.
Diverticulitis
- Pouches where the colon wall is weak. Often silent, but they can bleed.
- Inflamed: left lower belly pain, fever, nausea, a high white count.
- A CT scan confirms it. Colonoscopy waits 6 to 8 weeks: it could perforate the colon.
- Bowel rest, fluids, antibiotics, pain control: NPO in hospital, clear liquids at home.
- No fiber during the flare; once it settles, a high-fiber diet helps prevent more pouches.
Bowel obstruction
- Contents back up; the bowel swells and leaks fluid: dehydration, electrolyte loss and, if blood flow fails, perforation.
- Pain, distension, vomiting that may smell like stool. No gas, and no stool or only liquid stool.
- Bowel sounds may be loud early, then quiet or absent later.
- Potassium falls with vomiting. A high white count or lactic acid suggests necrosis or perforation.
- NPO, IV fluids, electrolytes, walking, fewer opioids. Some need surgery, which may create a stoma.
- Signs of improvement: bowel sounds return and the client passes gas.
NG decompression (Salem sump)
- Decompresses the stomach, prevents vomiting and measures the output.
- Large double-lumen tube; drains by gravity or suction, as ordered.
- The blue pigtail is the vent: never instill anything through it.
- Check placement before using the tube. Document drainage amount and color every shift.
- Turn the suction off before listening for bowel sounds.
- Suction drains sodium, potassium and magnesium: watch the labs. Frequent mouth care; check the skin where the tube rests.
Appendicitis or peritonitis
| Appendicitis | Peritonitis | |
|---|---|---|
| Cause | Appendix blocked, often by hardened stool, and it swells | Inflamed belly lining: perforation, rupture, or infection after surgery |
| Pain | Starts all over, then moves to the right lower belly; rebound tenderness | Very tender, worse with movement; may feel firm, like a board |
| Other signs | Loss of appetite, nausea and vomiting, fever | Fever, chills, a racing heart, nausea; little gas, stool or urine; curls up and guards the belly |
| Care | CT preferred (ultrasound for children and in pregnancy). Surgery; until then, NPO, IV fluids, antibiotics | An emergency: surgery, antibiotics, or both |
Before appendectomy: Urgent evaluation comes first: comfort measures like ice must not delay care, and heat is avoided. No enemas or laxatives. Rupture risk rises sharply 24 to 36 hours after symptoms start: report a change in pain or vital signs.
Ostomy care
| Care and teaching | |
|---|---|
| Colostomy | Colon through the belly wall, usually on the left; soft stool. Temporary (reconnected after about 12 weeks) or permanent |
| Ileostomy | End of the small intestine; watery output, so dehydration comes easily |
| Healthy stoma | Pink or red, moist, a little shiny. Swollen after surgery, shrinks over weeks; may bleed a little when cleaned |
| Report | Stoma turns purple, black or white, or pulls in below the skin. Frequent leaks, raw skin, foul discharge, bulging around it |
| Pouch | Empty at one third to one half full. Change per the system, the skin and the ostomy nurse's plan; at once for itching or leaks |
| Skin and fit | Mild soap and water, pat dry; no alcohol or oily products. Size the opening close to the stoma, not touching it |
| Ileostomy teaching | Follow the prescribed fluid plan; monitor urine and output; oral rehydration when indicated. Chew well: nuts, seeds, popcorn, corn and raw pineapple can block the stoma |
Gallbladder or pancreas?
| Cholecystitis | Acute pancreatitis | |
|---|---|---|
| Pain | Right upper belly, sometimes into the back or shoulder; trouble with fatty food | Upper middle (epigastric), often into the back |
| Key finding | Ultrasound shows stones. Murphy's sign: the breath stops short as the right upper belly is pressed | High lipase and amylase |
| Causes | Gallstones | Gallstones and heavy alcohol use |
| Treatment | Most need removal, usually by laparoscopy. Selected duct stones may come out first by ERCP | Monitored IV fluids, pain relief and early feeding, not prolonged NPO |
After gallbladder surgery
- Low-fat diet before and soon after surgery.
- Right shoulder pain after laparoscopy is common, from the gas. Walking helps; it eases within 2 to 3 days.
- Report jaundice: yellow eyes, light stools or dark urine can mean a stone was left behind.
Pancreatitis
- Mild: low-fat solid food usually within 24 to 48 hours, in small, frequent meals. Can't eat: nutrition by tube.
- Chronic: greasy, foul-smelling stools and weight loss; diabetes can develop. Give enzyme pills and vitamins A, D, E and K.
- Teach every client to stop alcohol completely, even after a mild attack, and to stop smoking.
Priority and safety calls
- ★ Day after colostomy surgery, the stoma is dark purple: report it to the surgeon now. Swelling is expected; a color change isn't.
- ★ Suspected appendicitis, and he asks for a heating pad: no heat; urgent evaluation comes first.
- Sudden cramping, a swollen stoma, vomiting and very watery output can mean a blockage.
- Pancreatitis with worsening pain, breathlessness or jaundice can mean infection or blockage, which can be fatal.
How the NCLEX tests it
- Colitis is even and bloody; Crohn's skips and forms fistulas.
- Diverticulitis: bowel rest and no fiber in a flare; fiber afterward.
- Traps: heat for appendicitis, laxatives before surgery, fiber in a flare, calling a purple stoma normal.
- Cholecystitis: right upper pain after fat, Murphy's sign. After surgery, jaundice is reported.
- Pancreatitis: epigastric pain to the back, high lipase, IV fluids, early feeding. Routine prolonged NPO is a trap.
