【简答题】
患者男性，66岁，因“受凉致发热、咳嗽、打喷嚏、胸闷、呼吸频率增加3日”来诊。患者有多年哮喘史，一直服用氨茶碱（每日3次，每次0.2g）和气雾剂。诊断：细菌性上呼吸道感染。给予口服红霉素抗菌治疗，服药2日后，出现烦躁、呕吐、心悸、血压下降现象，疑为氨茶碱中毒，临床医师申请对该患者进行治疗药物监测。该患者疑似茶碱中毒，治疗药物监测的依据是A、烦躁 B、咳嗽 C、血压下降 D、发热 E、心悸 F、呕吐 提示采用紫外分光光度（UV）法测定氨茶碱的血药浓度。与荧光偏振免疫分析（FPIA）法相比较，叙述正确的是A、UV法设备投入较FPIA法少，测试费用较低，更易普及 B、血样都需要做复杂的前处理 C、代谢物对两种方法都可能带来干扰 D、UV法测定的是吸收光谱的强度变化，FPIA法是测定发射光谱的变化 E、可以通过增加入射光强度提高UV法的灵敏度 F、两种方法都需要做质控 提示茶碱的有效血药浓度为10.0～20.0μg/ml，实验室的测定结果为25.4μg/ml。应做的处理是A、实验室高年资人员应该对结果进行复核，确保其准确、可信 B、结合症状，可以判断为茶碱中毒 C、建议立即停止使用红霉素，改用其他抗菌药 D、茶碱血药浓度升高的原因可能为红霉素使茶碱代谢减慢 E、不需知晓血样采集的准确时间 F、建议调整氨茶碱剂量，并继续定期进行血药浓度测定

【多选题】Which three IP multicast related statements are true？ （Choose three.）  （）
A.
Multicast addresses 224.0.1.0 through 238.255.255.255 are called globally scoped addresses. They are used to multicast data between organizations and across the Internet
B.
The multicast address 224.0.0.1 is a globally scoped address that has been reserved for the Network  Time Protocol （NTP） by the IANA
C.
Multicast addresses 239.0.0.0 through 239.255.255.255 are called limited scope addresses. They are  constrained to a local group or organization
D.
Multicast addresses 224.0.0.5 and 224.0.0.6 are limited scoped addresses that have been reserved for  OSPF
E.
Multicast addresses 224.0.0.0 through 224.0.0.255 are used for network protocols on local LAN segments. Because they are always transmitted with a Time to Live （TTL） of 1， they are never forwarded  by a router
