嗎啡（Morphine sulfate）為鴉片類藥物，主要作用於中樞神經系統，具有顯著的呼吸抑制（Respiratory depression）副作用。在給藥前，護理師必須評估呼吸速率與深度，這是確保病人用藥安全最重要的指標。若呼吸速率過低（通常定義為成年人 < 12 次/分），必須暫停給藥並報告醫師，以避免致命性的呼吸暫停。
Respiratory depression is the most serious and potentially fatal side effect of morphine sulfate administration. Therefore, assessing the respiratory rate and depth is the highest priority before giving the next dose to ensure patient safety. Although pain levels and consciousness are important, preventing respiratory arrest takes precedence over other assessments.
