正确答案是 C。A： 仅仅因为受伤导致工作变慢或效率下降，并不构成 OSHA 记录标准。除非该受伤导致了误工、限制性工作或医疗处置。B： 仅进行急救（First aid-only）处理的伤害，如创可贴包扎、冰敷等，明确被 OSHA 定义为“非记录性”伤害。C (正确项)： 根据 OSHA 标准，任何超出简单急救范畴的“医疗处置”（Medical treatment）均需记录。这包括处方药使用、缝合、骨折固定等正式医疗干预。D： 员工的持续抱怨（Constant complaints）属于管理沟通或人力资源范畴，除非涉及确诊的医疗状况且满足上述记录标准，否则不属于强制记录事项。A: A slower work pace due to injury does not automatically trigger an OSHA record. The injury must result in days away from work, restricted work duty, or specific medical treatment.B: Injuries treated solely with first aid—such as using bandages, splints, or cleaning minor wounds—are specifically exempted from OSHA recording requirements.C (Correct): Any injury requiring "medical treatment beyond first aid" is recordable. This includes formal medical intervention such as prescription medications, stitches, casts for fractures, or surgery.D: Constant employee complaints are administrative or interpersonal issues. They do not constitute a recordable illness unless a physician or licensed healthcare professional diagnoses a work-related condition.
