護理師為一群成人規劃健康促進活動。針對 50 歲以上個體，大多數機構建議進行哪項篩檢？
A nurse is planning health promotion for a group of adults. Which screening is recommended by most agencies for individuals over age 50?
- ATesticular exam睪丸檢查
- BLead level screening鉛含量篩檢
- CColonoscopy✓ 正解大腸鏡檢查
- DScoliosis screening脊椎側彎篩檢
健康促進與篩檢（Health Promotion & Screening）是預防醫學的基石。針對 50 歲以上的成人，美國預防服務工作小組（USPSTF）建議將大腸直腸癌篩檢列為常規項目。大腸鏡（Colonoscopy）不僅是診斷工具，還具備切除癌前病變（息肉）的治療功能，能顯著降低大腸癌發生率與死亡率，是此年齡層護理指導的優先事項。
Health promotion and screening are cornerstones of preventive medicine. For adults aged 50 and older, the U.S. Preventive Services Task Force (USPSTF) recommends colorectal cancer screening as a routine measure. Colonoscopy is both a diagnostic tool and a therapeutic procedure capable of removing precancerous lesions (polyps), substantially reducing the incidence and mortality of colorectal cancer, and is therefore a priority for nursing education in this age group.
美國大腸癌篩檢年齡建議已下修至 45 歲。台灣國民健康署目前的篩檢建議仍以 50-74 歲為主要對象，進行每兩年一次的糞便潛血檢查，若異常再安排大腸鏡。
