病人被給予靜脈注射 Gentamicin。哪項副作用需要立即介入？

Gentamicin 屬於氨基糖苷類（Aminoglycosides）抗生素，具有明確的耳毒性（Ototoxicity）與腎毒性（Nephrotoxicity）。耳毒性通常是累積性且可能為永久性的。耳鳴（Tinnitus）是聽神經受損的早期臨床警訊，一旦出現，護理師必須立即停藥並通知醫師，以防止聽力損失進一步惡化為不可逆的耳聾。臨床思路中，藥物副作用造成的器官功能損傷屬於優先處理事項（Safety）。

Gentamicin is an aminoglycoside antibiotic with well-documented ototoxicity and nephrotoxicity. Ototoxicity is typically cumulative and may be permanent. Tinnitus is an early clinical warning sign of auditory nerve injury; once it appears, the nurse must immediately stop the medication and notify the physician to prevent progression to irreversible hearing loss. Clinically, organ damage caused by medication adverse effects is a safety priority.
