4.臨床看護学
答え: A · A fall in blood pressure
これが答えになる理由
Young adults compensate for blood loss with tachycardia and vasoconstriction, so blood pressure may stay normal until a large volume is lost. Hypotension is therefore a late and serious sign.

15.感染管理と患者の安全
答え: C · Around the patient’s waist, over clothing
これが答えになる理由
The gait belt goes snugly around the waist over clothing, close to the center of gravity, with room for the nurse’s fingers underneath. Holding it gives control without pulling on the arms.
Coagulase-negative staphylococci are common skin flora. Growth in only one of several bottles, without a catheter or implant, most often reflects contamination during collection. Good skin antisepsis reduces contamination, which can lead to unnecessary antibiotics.確認に用いた資料:Blood culture · MedlinePlus (NIH) (2025)
