一位50歲且具有強烈早發性心血管疾病家族史的男性至社區診所就診。他最近剛被發現血壓為 145/90 mmHg。他告訴護理師：「既然我是高風險群，我想執行初段預防。我開始每天服用低劑量阿斯匹靈，並直接報名了心臟復健課程以防萬一。」根據公共衛生框架，護理師的哪段敘述準確釐清了預防的三段層次？
A 50-year-old male with a strong family history of premature cardiovascular disease visits a community clinic. He was recently found to have an initial blood pressure of 145/90 mmHg. He tells the nurse, "Since I'm high risk, I want to practice primary prevention. I started taking a daily baby aspirin and signed up for a cardiac rehabilitation class just in case." Based on public health framework, which statement by the nurse accurately clarifies the levels of prevention?
- A“Because you already possess uncontrolled hypertension, all measures including a healthy diet are now considered strictly tertiary prevention.”「因為你已經患有未控制的高血壓，所有措施包括健康飲食現在都被視為嚴格的最終預防。」
- B“Taking aspirin daily is actually secondary prevention because you are screening for side effects, while cardiac rehab is primary prevention.”「每天服用阿斯匹靈實際上屬於次級預防，因為你在篩檢副作用，而心臟復健屬於初級預防。」
- C“Both taking an aspirin to prevent clots and exercising in a rehab class successfully demonstrate the definition of primary prevention before a heart attack happens.”「服用阿斯匹靈預防血栓和在復健班運動成功展示了心臟發作前初級預防的定義。」
- D“Primary prevention involves lifestyle changes like a low-sodium diet; routine blood pressure screenings are secondary, and cardiac rehab is tertiary prevention.”✓ 正解「初級預防涉及生活方式的改變，如低鈉飲食；常規血壓篩檢屬於次級預防，而心臟復健屬於最終預防。」
本題測驗社區照護與健康衛教的核心觀念：疾病預防的三個層段（Levels of Prevention）。初段預防 (Primary Prevention) 發生在「罹病之前」，專注在防止疾病發生，如推廣低鈉飲食、運動習慣、以及施打疫苗。次段預防 (Secondary Prevention) 專注在「早期發現（篩檢）與早期治療阻止惡化」，例如常規測量血壓、乳房攝影，或在已有心血管風險但尚未發病時服用阿斯匹靈。末段預防 (Tertiary Prevention) 的重點在於「復健與減少永久失能」，例如心肌梗塞後參與心臟復健課程 (Cardiac rehab)、中風後物理治療等。選項D完美地將這三者的層級區分開來。選項B與C將屬於Tertiary的復健誤歸為初段或次段。選項A亦屬錯誤觀念，因為即使有高血壓，採取健康飲食仍然可視為阻止中風的預防手段，不代表所有行為全成了末段預防。
This item tests the three levels of prevention in community health. Primary prevention occurs before disease develops (e.g., low-sodium diet, exercise, vaccination). Secondary prevention focuses on early detection through screening (e.g., routine blood pressure checks, mammography) and may include prophylactic aspirin in those with risk factors but no disease. Tertiary prevention aims at rehabilitation and minimizing permanent disability after disease (e.g., cardiac rehab after MI, post-stroke physical therapy). Option D correctly distinguishes all three tiers.
三段五級的概念在台美社區護理常規中皆為核心基石（Leavell & Clark 理論）。對於篩檢（Screening）永遠隸屬於第二段的考試邏輯，更是兩邊國考的共同默契。
