NCLEX Question of the Day
Review the question, check the correct answer, and read the rationale before tomorrow's prompt arrives.
Which of the following is a primary prevention measure for colorectal cancer?
-
Genetic testing for familial risk
-
FOBT (Fecal Occult Blood Test) annually
-
Colonoscopy at age 50
-
Correct answer Dietary modification to include more fiber
Rationale
Primary prevention aims at preventing the disease before it occurs. Dietary modification to include more fiber can help prevent colorectal cancer by promoting regular bowel movements and reducing the risk of constipation, which could irritate the colon lining. Colonoscopy, FOBT, and genetic testing are secondary or tertiary preventive measures aimed at early detection or management of the disease.
