Colorectal Cancer — NCLEX Cheat Sheet
Colonoscopy at age 45Also known as: colon cancer · bowel cancer · CRC
Use this quick-reference guide to spot, treat, and prevent Colorectal Cancer on the NCLEX. Keep it handy during review and on exam day!
🩺📒 The 1-minute cheat sheet
🩺 Signs
- Change in bowel habits, narrow stool
- Rectal bleeding, blood in stool
- Unexplained anemia, weight loss
📌 Risk
- ↑ red/processed meat, low fiber
- FAP, IBD, family hx, age >50
📌 Dx
- Colonoscopy = gold standard
- CEA tumor marker → track recurrence
- FOBT/FIT screening, screen at 45
✅ Do
- Post-op colostomy → stoma pink/moist
- Dusky/black stoma → report NOW
📚 Colorectal Cancer — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Key points
Understand these first- Most colorectal cancers develop from adenomatous polyps, making screening and polyp removal highly preventive.
- Classic warning signs are a change in bowel habits (caliber/frequency), rectal bleeding, blood in the stool, and unexplained anemia.
- Right-sided tumors tend to cause occult bleeding and anemia; left-sided tumors more often cause obstruction and a change in stool shape.
- Risk factors include age over 50, family history, familial polyposis, inflammatory bowel disease, and a high-fat/low-fiber diet.
- Colonoscopy is the gold-standard screening and diagnostic test; CEA is used to monitor treatment response and recurrence.
- Treatment may involve surgical resection (sometimes with colostomy), chemotherapy, and radiation.
Nursing priorities
What to do, in order- Assess bowel elimination patterns and monitor stools for blood; track for obstruction or perforation.
- Provide preoperative bowel preparation and postoperative monitoring for ileus and anastomotic leak.
- Provide ostomy care and stoma assessment when a colostomy is created; the stoma should be pink/red and moist.
- Support nutrition and monitor for anemia, weight loss, and dehydration.
- Offer emotional support and body image/coping help, especially for ostomy adjustment.
Red flags — report now
Escalate immediately- A dusky, dark, or blue/black stoma indicates ischemia and must be reported immediately.
- Signs of bowel obstruction or perforation (severe abdominal pain, distension, rigidity, no stool/flatus, fever) require urgent action.
- Significant rectal bleeding or signs of acute blood loss need prompt evaluation.
Labs & values
Numbers to know- CEA (carcinoembryonic antigen): used to monitor treatment/recurrence, not screening
- Fecal occult blood / FIT: positive may indicate bleeding
- Hemoglobin/hematocrit: may be low from chronic bleeding
- Colonoscopy with biopsy: diagnostic
Patient teaching
What patients must know- Follow recommended screening (colonoscopy starting at age 45-50 or earlier with risk factors).
- Eat a high-fiber, low-fat diet; limit red and processed meats; maintain a healthy weight and stay active.
- Report any change in bowel habits, rectal bleeding, blood in stool, or unexplained weight loss.
- For an ostomy, teach pouch care, skin protection, and to report a dusky stoma or no output.
- Limit alcohol and avoid smoking, which raise colorectal cancer risk.
❓ Colorectal Cancer: NCLEX FAQs
What are the priority nursing interventions for Colorectal Cancer?
Assess bowel elimination patterns and monitor stools for blood; track for obstruction or perforation. Provide preoperative bowel preparation and postoperative monitoring for ileus and anastomotic leak. Provide ostomy care and stoma assessment when a colostomy is created; the stoma should be pink/red and moist. Support nutrition and monitor for anemia, weight loss, and dehydration.
What are the warning signs of Colorectal Cancer a nurse must report?
A dusky, dark, or blue/black stoma indicates ischemia and must be reported immediately. Signs of bowel obstruction or perforation (severe abdominal pain, distension, rigidity, no stool/flatus, fever) require urgent action. Significant rectal bleeding or signs of acute blood loss need prompt evaluation.
