物件、调整航向减小横摇、检查排水系统。错误项C：人员集中在船首会改变稳性且危险；错误项E：关闭主机随风漂流失去控制，易横浪倾覆。"},{"id":287,"type":"single","stem":"渔船在海上航行时，值班船员发现艏部甲板上一名船员突然倒地不省人事，此时最优先的处置动作是","options":["先将其扶起靠坐在舱壁上并喂水","立即呼叫救援并检查其呼吸和意识","马上背起伤者送往驾驶台找船长","原地等待其他船员一起商量怎么办"],"answer":[1],"explanation":"知识点：海上急救的现场处置原则。发现人员倒地应先评估意识与呼吸并呼救，这是急救链条的起点；扶起喂水可能造成误吸，背起搬运可能加重损伤，原地等待会延误救援。"},{"id":288,"type":"single","stem":"渔船消防中，机舱油类着火时，向火焰上喷射水柱这种做法的问题在于","options":["水会与燃油发生化学反应产生毒气","水会使油温快速升高引发爆燃","水柱会把浮油冲散扩大火面","水的温度太低无法接触火焰"],"answer":[2],"explanation":"知识点：油类火灾的扑救原理。油浮于水，用水柱冲击会使油层散开、火面扩大；水与燃油不会产生该类化学反应，喷水也一般不会直接使油温升高，更不是温度低的问题。"},{"id":289,"type":"single","stem":"渔船在能见度不良水域航行时，普通船员在瞭望岗位上应当做到的是","options":["站在驾驶台内透过玻璃窗观察海面","到船首等视线开阔位置加强目视瞭望","用手机播放音乐以保持清醒","每隔十分钟才到甲板查看一次"],"answer":[1],"explanation":"知识点：雾航瞭望要求。能见度不良时应到视线开阔的船首位置加强目视和听觉瞭望；在驾驶台内隔玻璃观察受限，播放音乐会掩盖声响信号，间隔查看无法及时发现来船。"},{"id":290,"type":"single","stem":"渔船锚泊时，普通船员在锚机操作附近配合抛锚，听到驾驶台发出抛锚指令后应先","options":["直接松开锚机刹车让锚自由下落","确认锚链附近无人并观察锚链走向","用手拉住锚链控制下落速度","先把锚链全部倒出再刹住锚机"],"answer":[1],"explanation":"知识点：抛锚作业安全程序。抛锚前必须确认锚链周围无人并观察锚链走向，防止人员被锚链带伤；直接松刹车自由落锚会失控，手拉锚链极其危险，先倒空锚链更不可能控制。"},{"id":291,"type":"single","stem":"船员在渔船上进行舷外作业时，按规定应穿戴的个体防护用品是","options":["普通棉质工作服和安全帽","救生衣和防滑工作鞋","雨衣和橡胶手套","隔热服和防尘口罩"],"answer":[1],"explanation":"知识点：舷外作业防护要求。舷外作业有落水风险，应穿救生衣并穿防滑鞋；棉工作服加安全帽不防落水，雨衣手套不解决落水防护，隔热服口罩与舷外作业无关。"},{"id":292,"type":"single","stem":"渔船发生碰撞后，船员发现舱壁出现裂缝并有海水涌入，此时正确的处置是","options":["立即用木楔和堵漏器材进行堵漏","打开进水舱室的门窗通风排水","先启动消防泵向进水舱室注水","等待船舶自然进水平衡后再处理"],"answer":[0],"explanation":"知识点：破损进水应急堵漏。发现进水应立即用堵漏器材控制进水；开门窗通风、向舱内注水都会加重进水，等待进水平衡会加速沉没风险。"},{"id":293,"type":"single","stem":"渔船在夜间航行时，普通船员发现船首方向有他船显示的两盏白灯上下垂直排列，这通常表示该船","options":["是一艘正在拖网的渔船","是一艘操纵能力受限的船舶","是一艘锚泊中的船舶","是一艘正在从事捕鱼的船舶"],"answer":[1],"explanation":"知识点：船舶号灯识别。垂直两盏白灯是操纵能力受限船（或吃水受限船等）的号灯；锚泊船显示锚灯，拖网渔船显示拖网号灯组合，普通捕鱼船显示红白捕鱼号灯，均与上下两白灯不同。"},{"id":294,"type":"single","stem":"渔船在海上遇到他船遇险需要施救，放救生艇前应首先确认的是","options":["遇险船是否已发出求救信号","本船救生艇的释放装置是否正常","遇险船员是否穿好救生衣","海面风浪是否已经减弱"],"answer":[1],"explanation":"知识点：救生艇施放程序。放艇前必须先确认释放装置正常，确保放艇过程本身安全；遇险船是否发信号、遇险人员是否穿救生衣、风浪是否减弱都不是放艇前本船首要确认项。"},{"id":295,"type":"single","stem":"普通船员在渔船厨房使用液化气灶后，正确的安全做法是","options":["先关灶具阀门再关钢瓶角阀","先关钢瓶角阀再关灶具阀门","只关灶具阀门不关钢瓶角阀","同时快速关闭两个阀门"],"answer":[0],"explanation":"知识点：液化气使用安全。正确顺序是先关灶具阀门使管内余气燃尽，再关钢瓶角阀；先关钢瓶会使软管内残气留存，只关灶具则钢瓶仍处于开启状态，同时快关不能排尽余气。"},{"id":296,"type":"single","stem":"渔船在港内加油时，甲板普通船员发现输油软管接头处有轻微渗油，正确处置是","options":["用棉纱缠紧接头继续加油","立即通知停止加油并报告船长","把渗油擦掉后继续观察","将软管接头抬高减少渗漏"],"answer":[1],"explanation":"知识点：加油作业的基本安全程序。发现渗漏必须立即停止作业并报告，防止溢油引发火灾。用棉纱缠紧继续加油属于带隐患作业；擦掉继续观察不能消除渗漏源；抬高接头不能解决密封失效。"},{"id":297,"type":"single","stem":"渔船航行中值班船员接到舵机失灵报告，在驾驶台未给出进一步指令前应","options":["立即减速并挂出失控信号","先维持原航向再报告轮机部","立即抛锚控制船位","先关闭主机再等船长"],"answer":[0],"explanation":"知识点：舵机失灵时的应急值班处置。舵机失灵应立即减速并显示失控信号，提醒周围船舶注意。维持原航向会继续偏航扩大危险；立即抛锚在航速下可能损坏锚机；先关主机失去动力反而更难控制。"},{"id":298,"type":"single","stem":"渔船在夜间航行时，普通船员发现左舷有一艘船显示红、绿两盏舷灯和两盏白灯，本船应判断该船","options":["正在锚泊且船长超过50米","正在航行且拖带长度超过200米","正在航行且长度小于50米","正在捕鱼且网具伸出超过150米"],"answer":[1],"explanation":"知识点：号灯识别。红绿舷灯加两盏白灯表示在航机动船，垂直两盏白灯为拖带长度超过200米的拖带船。锚泊船显示锚灯；小型船号灯配置不同；捕鱼船显示捕鱼号灯。"},{"id":299,"type":"single","stem":"渔船在海上遇到他船遇险，本船前往救助并接近遇险船时，普通船员应","options":["站在船首用探照灯直射遇险船","在驾驶台协助瞭望并准备救生器材","先放下救生艇再通知驾驶台","集中在船尾等待对方抛缆"],"answer":[1],"explanation":"知识点：海上救助接近遇险船的值班配合。应协助瞭望、准备救生器材并听从驾驶台指挥。探照灯直射会干扰对方视线；擅自放艇缺乏指挥；集中在船尾不利于应急反应。"},{"id":300,"type":"multi","stem":"渔船在雾中航行时，值班普通船员应做到的值班要求包括","options":["保持视觉和听觉瞭望并报告信息","按驾驶台指令协助鸣放雾号","擅自打开航行灯提高能见度","发现来船回波及时报告驾驶员","在雷达上锁定目标后即可离开瞭望位置"],"answer":[0,1,3],"explanation":"知识点：雾航值班的瞭望与协助要求。保持瞭望、协助鸣放雾号、及时报告回波都是正确值班行为。擅自开灯可能干扰号灯显示；锁定目标后离开瞭望位置违反持续瞭望原则。"}]}
