一位母親帶著她完全健康的 2 個月大女兒來到公共衛生診所進行排定的嬰幼兒健檢。女嬰出生時已接種了第一劑 B 型肝炎疫苗。母親緊張地看著時程表並問：「今天有太多針了。她小小身體一次承受不了。她今天到底『應該』接種哪些疫苗？」根據 CDC 的標準預防接種時程表，護理師應準備在 2 個月大的訪視中施打哪些疫苗？
A mother brings her perfectly healthy 2-month-old daughter to the public health clinic for a scheduled well-baby visit. The infant received her first dose of the Hepatitis B vaccine at birth. The mother nervously looks at the schedule and asks, "There are so many shots today. Her tiny body can't handle all these at once. Which ones is she actually supposed to get today?" Based on the standard CDC immunization schedule, which vaccines should the nurse prepare to administer at the 2-month visit?
- AMMR (Measles, Mumps, Rubella), Varicella, and the first dose of DTaP combined.MMR（麻疹、腮腺炎、德國麻疹）、水痘疫苗，以及第一劑 DTaP 合併疫苗。
- BSecond dose of Hep B, and the first doses of RV, DTaP, Hib, PCV, and IPV.✓ 正解B 型肝炎第二劑，以及 RV、DTaP、Hib、PCV 和 IPV 的第一劑。
- CThird dose of Hep B, and the second doses of RV, DTaP, and Hib only.B 型肝炎第三劑，以及僅 RV、DTaP 和 Hib 的第二劑。
- DFirst dose of the live-attenuated Influenza vaccine along with the second dose of IPV.減毒活株流感疫苗第一劑，連同 IPV 第二劑。
本題測驗 CDC 最新發布的幼兒預防接種時程表（Immunization schedule）。2個月大是嬰兒首次面臨大量常規疫苗的經典時機。記憶口訣為『B-DRHIP』。在 2 個月時，嬰兒應接種：第二劑 B 型肝炎（Hep B）、第一劑輪狀病毒（RV）、第一劑白喉-破傷風-非細胞性百日咳（DTaP）、第一劑 B 型嗜血桿菌（Hib）、第一劑肺炎鏈球菌（PCV）以及第一劑不活化小兒麻痺（IPV）。因此選項B是正確的完整清單。選項A的 MMR (麻疹/腮腺炎/德國麻疹) 與 Varicella (水痘) 屬於活性減毒疫苗，根據規定「必須」等到嬰兒滿 1 歲（12個月大）時才能施打，2個月打會被母嬰抗體中和而無效。選項D的流感疫苗 (Influenza) 最快要到 6 個月大時才能開始施打。選項C的劑次描述錯誤，第三劑 Hep B 通常在 6 個月大才給予。
This tests the latest CDC childhood immunization schedule. Age 2 months is the classic time for an infant to face multiple routine vaccines. A useful mnemonic is 'B-DRHIP.' At 2 months, infants receive: 2nd dose of Hepatitis B (Hep B), 1st Rotavirus (RV), 1st DTaP, 1st Hib, 1st PCV, and 1st IPV. Therefore B is the correct complete list. A's MMR and Varicella are live attenuated and must wait until at least 12 months because of maternal antibody neutralization. C's Influenza vaccine is not given before 6 months. D's dose numbers are wrong; the 3rd dose of Hep B is usually at 6 months.
世界大部分國家依照 WHO/CDC 指引，2 個月大都是所謂「五合一」或「六合一」疫苗的大關卡。台灣目前的五合一 (DTaP-Hib-IPV) 加上 PCV 與 RV，施打週期為第 2, 4, 6 個月，這規則與 NCLEX 美國 CDC 時程重疊度達 95%。
