代謝性酸中毒的特徵是血中碳酸氫根離子(HCO3-)濃度下降(正常值約 22-26 mEq/L),導致 pH 值降低。選項 A 的 HCO3- 偏低符合酸中毒定義。pH 7.48 為鹼中毒,PaCO2 48 mmHg 為呼吸性酸中毒補償表現,PaO2 95 mmHg 則為正常氧合指標。
The USPSTF recommends biennial screening mammography for women aged 50 to 74 years to effectively detect breast cancer early and reduce mortality. While annual screening may be considered for some, the standard guideline supports every two years for this age group.
