A 77-year-old male who is otherwise healthy presents for his routine exam. His last colonoscopy was at age 70 years with no polyps detected. He asks the nurse practitioner when he should have his next colonoscopy. The NP discusses the risk versus the benefits of continued screening with the patient and advises:

Choice A reason: While colonoscopy every 10 years is standard for average-risk individuals, continued screening in older adults should be individualized. Automatically scheduling another colonoscopy may not be necessary without considering life expectancy and prior results. Choice B reason: Guidelines suggest that adults aged 76–85 may choose to continue or discontinue colorectal cancer screening based on overall health, prior screening history, and personal preferences. Since this patient had a normal colonoscopy at age 70 and is otherwise healthy, shared decision-making is appropriate. Choice C reason: Scheduling a colonoscopy at age 80 is arbitrary and not guideline-based. Screening intervals should be based on prior findings and individualized risk assessment. Choice D reason: Blanket cessation of screening at age 77 is not recommended. Decisions should be personalized, especially in healthy individuals with a long life expectancy.
