護理師在兒童保健門診評估一名 4 歲幼童。下列哪項臨床發現需要針對健康維護進行立即的追蹤？
A nurse is assessing a 4-year-old child during a well-child visit. Which clinical finding requires immediate follow-up related to health maintenance?
- AThe child is unable to ride a tricycle.該兒童無法騎三輪車。
- BThe child cannot spell their last name.該兒童無法拼寫自己的姓氏。
- CThe child’s Body Mass Index (BMI) is at the 97th percentile for age and sex.✓ 正解該兒童的身體質量指數（BMI）位於同齡同性別的第 97 百分位。
- DThe child has not yet lost any primary teeth.該兒童尚未掉任何乳牙。
4 歲幼童的評估重點包含生長發育與生活形態。選項 C（BMI 在第 97 百分位）屬於「肥胖」（Obesity），這在健康促進中是一個嚴重的警訊，預示未來心血管疾病、糖尿病及社交心理問題的風險，必須立即進行飲食與活動習慣的介入。選項 A（騎三輪車）通常在 3 歲發展，4 歲若不會雖需關注，但不若肥胖問題對長期健康影響深遠；選項 B（拼寫姓氏）對於 4 歲孩子來說尚非必備的認知里程碑（通常是幼兒園大班或小一）；選項 D 正確，4 歲尚未換牙是完全正常的（通常 6 歲開始）。臨床決策應優先處理會導致慢性病發展的生理指標。
Assessment of a 4-year-old child includes growth, development, and lifestyle. Option C (BMI at the 97th percentile) is classified as obesity, which is a major warning sign in health promotion and predicts future risks of cardiovascular disease, diabetes, and psychosocial problems; immediate intervention in diet and activity habits is required. Option A (riding a tricycle) is typically a 3-year-old milestone; while inability at age 4 warrants attention, it is less significant for long-term health than obesity. Option B (spelling a last name) is not a required cognitive milestone for a 4-year-old (this typically occurs in late preschool or first grade). Option D is correct: not yet having lost any primary teeth at age 4 is entirely normal (loss usually begins around age 6). Clinical decision-making should prioritize physiologic indicators that may lead to chronic disease.
美國非常重視 BMI 繪製與早期肥胖介入，因為其兒科肥胖盛行率極高。台灣近年來兒科肥胖率也攀升，護理師在衛教時需特別注意含糖飲料（手搖飲文化）對幼童 BMI 的負面影響，並納入家庭衛教重點。
