A nurse is caring for a patient with multisystem organ failure (MSOF) in the intensive care unit. Which assessment finding would be the MOST critical indicator requiring immediate intervention?
1Serum creatinine level of 3.2 mg/dL with oliguria
2Mean arterial pressure (MAP) of 55 mmHg with weak peripheral pulses✓ 정답
3Platelet count of 85,000/μL with petechiae on extremities
4Arterial blood gas showing pH 7.32 with HCO3- of 18 mEq/L
해설
MAP below 60 mmHg indicates inadequate tissue perfusion requiring immediate intervention to prevent organ damage in MSOF. Other findings are concerning but less immediately life-threatening.

この問題は、多臓器不全 (Multiple System Organ Failure: MSOF)の患者において、最も緊急性が高く、直ちに介入を要するアセスメント所見を特定する能力を問うています。MSOFは、全身性炎症反応症候群 (SIRS) や敗血症 (Sepsis) などが進行し、2つ以上の臓器系が機能不全に陥った状態です。このような患者の看護では、ABC(気道・呼吸・循環)の優先順位に基づき、生命を直接脅かす状態を最優先で見極めることが求められます。
