我们逐题结合语境和语法知识点分析：
1. 第1题：接电话的固定表达是answer the telephone，hurry to后接动词原形，此处it指代电话，直接用answer，不需要加to，tell（告诉）不符合语境，选A。
2. 第2题：固定句型it takes sb. some time 表示“做某事花费某人多长时间”，主语it是第三人称单数，动词用takes；spend的主语必须是人，use不符合此处用法，选B。
3. 第3题：固定表达something is wrong with sb. 表示“某人出了状况/不对劲”，结合后文孩子吞了笔的情节，是发现孩子状态不对，选C。
4. 第4题：结合后文孩子指着自己的嘴、吞了笔的情节，可知两岁的孩子没法正常告诉妈妈发生了什么，can't表示“不能”，选B。
5. 第5题：“疑问词+不定式”结构中what to do表示“该做什么”，what在句中作do的逻辑宾语，符合“她不知道该怎么办”的语境，选C。
6. 第6题：后文紧接着是她打电话和对方对话的内容，可知她跑向电话求助，不是直接去医院，选C。
7. 第7题：后文提到医生两三个小时之后才回来，说明医生现在外出了，be out表示“外出、不在家/办公室”，选A。
8. 第8题：knowledge是不可数名词，little修饰不可数名词，表示“几乎没有”，符合“新助理几乎没有医药知识、帮不上忙”的语境；few/a few只能修饰可数名词，选C。
9. 第9题：孩子误吞了笔，现在急需医生的帮助，help符合语境，选C。
10. 第10题：固定表达I am sorry about that 用于告知对方不便的消息时表达歉意，符合助理告知怀特夫人医生不在的语境，选B。
